1 Introduction
The Telemisis Telemetry Solution, branded SiteWatch or GenTrak enables remote monitoring and control of fixed or mobile equipment and unmanned sites containing technical equipment e.g. generators, cellular basestations, water pumping stations etc. It uses the mobile „phone network GPRS and Text Messaging Services for communication and, optionally, GPS (Global Positioning System) for location tracking. All data is channelled to the Telemetry server via the cellular data network or, optionally, the Iridium satellite network. For convenience we will use the term SiteWatch throughout this document but note that the majority of the content of this manual relates to both SiteWatch and GenTrak. SiteWatch GTT3 telemetry units interface with a range of equipment including Intelligent Generator Controllers, compressors, chillers, air-conditioning equipment, security devices and other devices via analogue and digital connections.
Please refer also to specific site commissioning procedure if applicable.
Note: this manual no longer includes any specific instructions for GTT2 units.

2 GTT Units
2.1 How the Telemetry Units Work
The Generic Telemetry Terminal (GTT3) includes four main components:
Main circuit board including ARM7 microprocessor, memory, power supply and physical interfaces
GPS unit (incorporated in XT65 module).
GSM/GPRS interface module including programmable Java processor.
Lithium-polymer battery.
Integrated inputs, outputs and communications interfaces (RS232/RS485)
Optional, additional I/O daughterboard module.
The GTT3 derives its primary power from an external DC supply in the range 6-30V. The power supply would normally be provided by the equipment already on site, for example, a rectifier, generator starter battery or battery bank. If the external DC power supply should fail, the unit will continue to operate until its internal battery is exhausted. Typically, this would be a period of 6-10 hours.
If the unit stops operating due to low battery then it will restart automatically when the external power is re-applied.
At start-up, the GSM/GPRS module and the ARM microprocessor both initialise and their respective installed firmware communicate over an internal connection. The unit then establishes and maintains communication with the SiteWatch server. The start sequence is as follows:
1. Power applied or unit started using the START button when hibernated. 2. ARM microprocessor enters its “bootloader” program and waits for up to ten minutes whereupon it
will reset the cellular module if there has been no communication 3. Startup delay for cellular module – usually programmed at the factory to 20-60 seconds. This delay
allows a short period for the connection of a laptop to reprogram the cellular module. 4. Cellular module starts up. 5. ARM microprocessor is commanded to start its firmware 6. ARM and cellular module communicate and the ARM is “configured” with configuration settings
stored in flash memory of the cellular module. Note: During this initialisation process the STAT/SYS LED will output code 7 for a period of time.
7. Cellular module establishes connection with the server and downloads any configuration changes
If communication between the ARM and the cellular module fails then after 10 minutes the ARM will physically reset the cellular module and vice-versa. This is known as a Watchdog function.
When a GTT3 is connected to the SiteWatch server it becomes a SiteWatch Unit. In the SiteWatch system a SiteWatch Unit is a collection of features, functions and data related to that unit i.e. much more than just the GTT3 hardware itself.

3 Installation Overview and Pre-Planning
3.1 Before You Visit Site
Test the SIM card you intend to use
Test your SiteWatch unit
Ensure that you have all the correct tools
3.2 Explanation of GTT Cellular Module Operating Sequence
When the cellular module powers up it operates as follows. Note that you should follow the documented installation and power-up procedures when on-site or the GTT test procedures as defined in section 3.5.
1. Internal hardware tests are executed
2. The internal cellular module and ARM microprocessor start and synchronise with each other. The installed firmware in the cellular module starts.
3. The GTT sends a registration request via text message to the SiteWatch server address that is included in the firmware (actually this is the „phone number of a cellular GSM modem attached to the server). You may have a special version of firmware that bypasses this stage and connects directly to a designated server in which your unit will be marked with a sticker specifying the server‟s IP address. Alternatively, the default registration server provides details of the network GPRS settings and the server IP address in the response to the registration request.
4. The GTT saves the network settings information and attempts to establish a connection to the SiteWatch server over the GPRS network. If this process fails repeatedly then the unit will attempt to connect after half an hour or so to the designated server using SMS text messaging.
5. If this process fails then there are various means of troubleshooting and re-configuration steps that can be taken to solve the connection problems. Please refer to the troubleshooting section for further help.
6. Once the unit has successfully connected to the SiteWatch server it will be hosted on the default node in the system hierarchy until configured and associated with an Asset.
At all times during this process you may observe the LED states and/or examine the debug output from the GTT debug port to determine what, if anything is going wrong.
3.3 SIM Card/Subscription Requirements
Your SIM Card subscription must be provisioned at a minimum with text messaging sending and receiving capability. If the registration server is in another country from where the unit is being installed then the ability to send international text messages must also be enabled if the unit has been provisioned with firmware that carries out a registration procedure. In addition, if you wish your GTT unit to use the GSM/GPRS packet data network to communicate with the SiteWatch server then the subscription should be enabled for GPRS Internet access. Note that WAP access via GPRS is not sufficient; general internet access must be provided.
The following outgoing TCP ports 8080 (GTT connection to server) and 9056 (GTT remote firmware update) should be enabled for the GPRS connection. You may need to check with your cellular operator that these ports are not blocked by their firewall.
3.4 Testing a SIM Card and Cellular Subscription
If you are using a new type of SIM card or a SIM card from a different network operator than you have tested before then it is imperative that you confirm basic operation of the cellular subscription linked to the SIM card before proceeding further.
Page 12 of 81 Version 3.2
3.4.1 PIN Code Check
First, insert the SIM card [A] into a mobile „phone and check that the „phone registers with the local network as expected. If a PIN code is required by the SIM then you must ensure that this PIN code lock setting is removed. It does not matter if a lock code is applied to the „phone; it‟s the SIM card that matters.
3.4.2 Text Messaging (SMS) Tests
Text messaging is used for number of purposes by the SiteWatch unit:
Initial registration with the SiteWatch server in the UK (or elsewhere by special agreement). Registration may be omitted for certain firmware builds but this is normally only done by special arrangement with the customer.
Sending commands to and from the SiteWatch unit from mobile „phones
Sending alarms to mobile „phones
Communications (optional, according to defined system configuration) with the SiteWatch server if the GPRS connection mode fails.
With the SIM card [A] in a mobile „phone, first send the text message “Test” (without the “ characters) to the „phone number of the GSM modem connected to the SiteWatch server (default unless you have been informed otherwise is +447833256997). You should receive a text message response “OK”. This step proves that the GTT should be able to send the registration text message to the SiteWatch registration server and that the server can successfully respond. If you do not receive the OK response then try sending a text message from the „phone with SIM [A] to another GSM „phone on the local network. If this test passes, try sending the same message to a UK „phone in the UK and ask that person to send a reply. If this test passes but you still do not get a response from the Telemisis Server then please contact Telemisis for further advice.
If SMS sending from SIM [A] fails completely then check that the correct SMSC address is configured for the SIM card [A]. Most GSM „phones allow this to be checked and modified in the Message Settings. If you do not know the correct SMSC address to use then contact your SIM card supplier or local network operator. For most networks the correct SMSC address can be found on the web at http://www.g24.li/smsclist.
If SMS receiving to SIM [A] is failing completely then contact your network operator.
If SMS sending from SIM [A] to the UK or to SIM [A] from the UK is failing completely then contact your network operator.
3.4.3 GPRS Data Checks
Once you have proven text messaging capability you should prove that the subscription is configured correctly for GPRS internet access by using the „phone itself or a connected laptop to prove that the SiteWatch server can be accessed. If you cannot for instance access www.google.com then you must resolve this problem before proceeding unless you intend to operate the SiteWatch units using text messaging alone.
Proving basic internet access using these procedures is particularly important if you are using a roaming SIM card.
If your units will be connecting to one of Telemisis‟ SiteWatch servers, enter the following URL into your mobile or laptop:
http://test.telemisis.com:8080
Version 3.2 Page 13 of 81
If you receive back a simple web page containing the text “Test Successful” then you can be nearly sure that your SIM card subscription should enable your SiteWatch unit to connect with the Telemisis server. However, there still remains a small chance that your chosen cellular network can block connections to the SiteWatch server. Should you see the Error Code 4 on the GTT SYS LED when you have inserted the SIM card, then contact Telemisis support for further help.
For a final definitive test you can carry out the instructions below for testing the connection using telnet.
If your units will be connecting to your own SiteWatch server, you should check that the SIM card subscription will enable the GTT to connect to the server by attempting to establish a telnet connection to the server using the SIM card in a data card or mobile „phone and attached to a laptop or desktop computer. Once you have established a GPRS connection to the mobile network through your data card or mobile „phone, start the Windows command line application “cmd” and enter the following command:
telnet <SiteWatch public IP address> <SiteWatch Connection Port>
The public IP address will have been allocated by your ISP or by your mobile network‟s IT department in the case that your SiteWatch server is connected to a mobile network‟s internal data network. The SiteWatch Connection Port will be configured in your SiteWatch system; by default it will be either 82 or 8080.
If the connection cannot be established from the mobile device to the SiteWatch server then you will see the message “Connection failed”. In these circumstances you should contact the provider of the SIM card or their roaming partner to determine the reason for the failure.
3.5 Testing a SiteWatch Unit Before Installation
Once you have proven the basic network services provided by the local operator and their SIM card, you can proceed with the testing of the SIM card in the SiteWatch unit.
Connect a dual-technology antenna and ensure that it is placed in a position that has a good view of the sky.
Plug in the SIM card with the cut corner facing inwards and the contacts upwards. Ensure that it is firmly located in the slot.
Warning: take care when inserting the SIM card to ensure that it locates directly into the SIM card carrier. It is possible if the SIM is inserted at a slight angle to the horizontal that it may miss the carrier and fall into the internals of the GTT. If this happens you will need to remove the front panel of the unit to retrieve the SIM card.
Warning: if you insert a SIM card into a live unit you must restart the unit after inserting the SIM. To restart the unit, press and hold the STOP button for 2-3 seconds until all of the LEDs go OFF except for the red POWER LED. In some circumstances the unit may restart when you release the STOP button but in other circumstances you will need to press either the START or RESET button.
If you know that the internal battery is connected then there is no need to undo the front panel. GTT units are normally shipped with the battery connected. If the GTT unit has been without external power for a reasonable period then there is a chance that the battery is exhausted. This doesn‟t matter, except that you will need to have a power supply to get started with further tests.
The GTT may be in “hibernation” mode if it is fresh from the production line. Using a fine screwdriver or other small, rigid device press the START button. If the LEDs start flashing then the battery has some charge. If the LEDs don‟t flash then connect a power supply and press the START button if the LEDs don‟t start flashing by themselves. Note that the unit will operate without the internal battery being connected and it is not possible to determine from the LEDs whether the battery is connected or not. Refer later, if necessary, to the GTT battery status on the SiteWatch server or remove the front panel and check or wait five minutes to give the battery time to charge and then remove the power. If the LEDs remain active then you know that the battery is installed correctly.
Page 14 of 81 Version 3.2
If your unit is installed with firmware which executes a registration process then, if the registration process fails the code 2 or 3 will be displayed on the STATus LED.
Once registered, or if your firmware is configured with the settings for the SiteWatch server already, the unit should attempt to connect to the server using the GPRS network. If the connection cannot be established then code 4 will be displayed on the STATus LED.
If you cannot resolve the communications issues and get to the point where the unit has not connected to the SiteWatch server then you should not proceed with on-site installation before the problem has been resolved.
3.6 Tools for GTT Installation
Be sure that you have the following tools:
1. Laptop with USB port and mini USB cable. A suitable cable is available from Telemisis. Laptop loaded with:
a. Bray v 1.9b terminal program or equivalent e.g. Windows HyperTerminal
b. Cinterion Module tools
c. N-link ARM JTAG programming unit and software
2. GTT3 debug cable (mini USB)
3. T10 Torx driver in case you need to open the GTT unit
4. HSS drill bits and power drill
5. General toolkit
6. Multi-meter
3.7 Planning
Plan in advance what cables and connectors will be required
Plan the cable runs to provide maximum protection from pinching, crushing and overheating.
Locate suitable locations for each SiteWatch/GenTrak unit.
Find suitable locations for antennas
Note that the power supply cable to the GTT must not be longer than 3 metres.

Connect the USB cable to the USB mini connector on the front of the GTT and directly to the laptop.
Using either Bray Terminal or Windows HyperTerminal, configure a serial connection and open the connection. The first example shown uses Bray Terminal program and the second, Windows Hyperterminal:
Note: If the GTT3 or the internal XT65 module restarts for any reason then you may need to follow this procedure to enable your terminal program to start logging data again:
Disconnect USB cable
Click disconnect button or icon in your terminal program
Reconnect the USB cable
Click connect
4.1.1 Bray Terminal
Configure as shown below using a baud rate of 115200. Note that you must install the Cinterion USB port drivers before connecting the GTT3 debug cable and you should determine the serial port to use as described in section 15.3.
Click “Connect” to start monitoring the data. Click Start Log if you need to collect a debug log to send to Telemisis.
Page 16 of 81 Version 3.2
4.1.2 HyperTerminal
Note that HyperTerminal is not as reliable as Bray. Also, HyperTerminal is not included with Windows Vista so we normally recommend that Bray is used where possible.
4.1.3 Some Sample Debug Output
This is what you will see if there is no SIM installed or if the GTT cannot read the SIM because of dirty contacts for instance.
This is what you will see if the SIM is installed but the stored GPRS settings are incorrect or if the SIM is not enabled for GPRS network access. Note also, that you can see the signal level of the local network “+CSQ=13”, where 0 means no signal and 63 is excellent. Note also the warning that the SIM card has changed. If the installed firmware includes the GTT registration option then a change of SIM will force a re-registration to occur.
Version 3.2 Page 17 of 81
4.1.4 Increasing the Level of Debug
You may increase the information level of the debug output by sending a DEBUG SMS command to the unit but only if the mobile „phone that you are sending the message from is configured in the SMS Administration list for that unit. For your number to have been configured in the GTT, the unit must have been connected to the Server at some point after the number was configured in the SMS administration list.

1. Follow the mounting instructions provided with the antenna.
2. Mount antenna within 5 metre cable run (or less if you have purchased a shorter cable) from the GTT unit. When routing the antenna cable you should never loop or coil the cable.
3. Connect the Antenna cable(s) to the GTT unit as shown in Figure 8. Finger-tighten the connections carefully, taking care not to twist the cables themselves. The connectors twist independently of the cable.
Figure 8 Antenna Connections
5.3 Inserting SIM and Connecting Internal Battery
Before mounting a GTT unit;
1. If necessary remove the front cover by undoing the Torx screws and connect the red, black and white battery lead to its connector. To check whether the battery is connected you must either remove the front cover or log on to the SiteWatch server and check the GTT battery status. The latter may be difficult is the unit has not yet been commissioned! Note, however, that GTT units are always shipped from the factory with the battery connected.
2. Insert SIM card.
3. Replace the front cover.
4. Connect the antennas.
5. Connect external DC power.
After approximately 3 minutes, check that the LEDs display as follows:

The System Status LED may report a problem by means of a flashing code as described in Table 22. If the GTT unit has been configured to expect connection of, for example, a certain type of controller then if that controller is not yet connected an error code will be shown at this stage.
5.4 Mounting GTT Units
First you must locate suitable mounting points that are free from moisture, excessive fine dust and not subject to high temperatures above the operating range of the hardware. Note that sustained high temperatures may result in intermittent operation of the GTT and may cause long-term damage to the hardware and battery. Mount the GTT unit using one of the following methods:
Double-Sided Adhesive Pad
1. Thoroughly clean the mounting surface and the back of the GTT with degreaser and allow to dry. A degreasing wipe is supplied along with each adhesive pad.
2. Fit pad to GTT unit (do not touch pad surface)
3. Fix GTT unit to mounting surface as shown in Figure 9
Figure 9 Mounting GTT with Adhesive Pad
Mounting Brackets with Screws, Bolts or Rivets
1. Slide the mounting brackets onto the GTT chassis. Note that you will have to remove and replace the front cover to do this.
2. Using the GTT Unit as a template, mark the positions of the holes on the mounting surface.
3. Centre-punch the spots you have marked.
4. Drill holes of relevant size taking care to avoid equipment on the reverse side of mounting point.
Page 22 of 81 Version 3.2
5. Secure the mounting bracket using the relevant fixings with appropriately sized retaining washers.

Version 3.2 Page 23 of 81
6 Cable Installation
Telemisis recommends that the following practices are adopted in the site installation:
Use a separate fused power source for each piece of equipment that requires DC power
Monitored equipment and circuits such as motion sensors, gate sensors, tamper circuits etc should be supplied with circuit voltage from a separate fused supply source
Ensure that all power circuits use suitably dimensioned power wiring
Where possible use Latch-Low type circuits for monitoring. This ensures that breaks in the wiring are detected as well as the circuit alarm condition
Wherever possible use connector blocks or cage clamps to connect circuits to the GTT and power supplies
Route external wiring through conduits or ducting and do not expose wires to prolonged sunlight or heat
Never run signal cables such as analog or digital signals, RS232 or RS485 links etc in the same ducting as cables carrying alternating current (AC)
Always connect wiring with power off and then check the circuits using a multi-meter before connecting power
6.1 Cable Running and Planning
Cables must be run either through ducting or PVC pipes to protect them. All such ducting and pipe work must be installed level and square. When cables have been pulled through, label them with the destination.
Note: The GTT unit MUST only be operated in negative ground electrical systems. Check the ground polarity before installation.
Note: Under no circumstances must the antenna cable or cables be looped or coiled.
6.2 Screened Cable
Where screened cable is available for use in SiteWatch installations then it is good practice to ground the screening.
Attach the screening where best site ground is afforded.
Screening should be attached to site ground at one end of each cable length only. If screening is grounded at each end then it can become a conduction path of electrical noise and interference.
With the outer insulation of the cable stripped back from the conducting cores, the foil screening and its drain wire (conducting core) will be visible.
Trim back the foil screening.
At the required end of termination, attach the drain wire to site ground insulating any exposed drain wire to avoid possible short circuits.
The drain wire can be extended where required.

6.8 GTT COM Ports and Their Assignments
GTT3 units are equipped with either two or three COM ports depending upon the factory options ordered. The standard configuration however is for COM1 to be RS232, COM2 is RS232 and COM3 is RS485. The SiteWatch server will automatically assign these COM ports according to options selected in the Unit Configuration.
GTT COM ports will be automatically configured with communication interface settings to match the most
commonly found default settings of the attached device. Refer to Table 16 for a list of equipment controllers and their normal interface settings. Note: if your controller uses different interface settings and you cannot change them to match the Telemisis settings then you may modify the specific interface settings in the Unit Configuration page of the SiteWatch server.
GTT3 Port Name Notes
COM1/RS232 RS232 Connection of an RS232 capable intelligent equipment controller.
COM2/RS232 RS232 Connection of an external serial modem.
COM3/RS485 RS485 For connection of an intelligent RS485 based equipment controller dependent upon unit configuration.
Table 7 GTT3 COM Ports
6.8.1 RS485 Connection for Intelligent Controller (IC)
If you are connecting an IC to the GTT via RS485 then you will probably have purchased a special cable from Telemisis. It may not be necessary to connect Ground between the GTT and the IC; you should consult the instructions from your IC supplier for clarification.
Note: You may need to fit a terminating resistor to the connection. Refer to IC supplier’s instructions.

7 Power Supply
Note: if you use an alternative power source than the Telemisis site power supply, you MUST ensure that it can deliver at least 1A at 12VDC. Less powerful supplies may cause intermittent faults with your GTT under some circumstances.
Figure 21 Site PSU in Context
7.1 Power Supply Installation
Before mounting the Telemisis Power Supply, decide on the mounting point and the routing of input and output cables to the supply. Knock out one or two cable routing holes and install the supplied grommet(s).
Install the power supply on a flat, vertical surface near to the GTT mounting point if possible. Bolt or screw securely to the surface.
Install the battery inside the PSU but do not yet connect the terminals. Ensure that the terminals are located at the right-hand side of the PSU and away from the main transformer otherwise there is a chance of short-circuit.
Locate the Fused Output Module (FOM) on the lid or adjacent to the battery using the sticky mounting feet. Ensure that the lid will close.
7.2 Cable Routing
Remove the cartridge fuse and connect the main supply cable from the site mains supply. The main supply should be rated at least 2Amps.
Route the power cables from each of the fused outputs to the Wago cage blocks or other connector bank. A single multi-core cable can be used for this purpose or separate cables but ensure that each cable core is correctly sized for the required application.
The power cable to the GTT must be connected to a FOM output equipped with a 2A fuse. If necessary, replace the standard 500mA fuse with a 2A fuse. Note that the power supply cable to the GTT must not be longer than 3 metres.
Wire the tamper circuit to the GTT as shown in your site schematics

8.3 Analogue Inputs
The analogue inputs work by virtue of a voltage divider. This allows for any signal up to 15v to be monitored. The input impedance is 56.3 kOhm which should be borne in mind when coupling the device to sources. Typical output impedance of devices like voltage based fuel sensors is 100 Ohms which works perfectly.
Note: take great care not to plug analog inputs cable into the digital inputs or digital outputs positions otherwise permanent damage to your GTT may be caused.
Version 3.2 Page 33 of 81
8.4 Rugged Digital Input (Daughterboard and GTT3 Mainboard)
The rugged digital inputs should be used as the preferential digital input, due to their ability to handle up to 24v signals. The GTT contains an internal Pull-Up resistor on these inputs, such that they can be switched with NC/NO contacts and when left in an open state they will always read LOW (off). Therefore, if not driven HIGH any other condition will be considered low, either when held at 0V or left floating.
The GTT Unit can be used to interface with existing alarm systems or terminate alarm contact pairs from other sources.
There are 3 methods in which the GTT can interface with sensors using either Normally Open (NO) or Normally Closed (NC) types of circuits.
1. Externally powered contact with power from device (EMU-IN1)
2. Externally powered contact with power from common power suply (EMU-IN2)
3. Direct sense from GTT Powered Contact (GTT_IN)
Figure 22 Digital Inputs Circuit Examples
Where BAT1 is the Telemisis external power supply or other PSU.
1

3
Page 34 of 81 Version 3.2
Note that contact based inputs to the GTT will be terminated on a circuit with relatively high impedance. The power supply of any external equipment driving the circuits must be capable of delivering sufficient current so that the line voltage does not drop significantly.
The alarm circuits, EMU and GTT must have a common and reliable ground connection.
8.5 Rugged Digital Outputs (Daughterboard and GTT3 Mainboard)
The rugged digital outputs are intended to sink current, in order that loads can be switched. If they are required to provide a voltage output, they must be fitted with external pull up resistors. A suitable value resistor is 10 kOhm and the EXT_POWER Source (VPullUp) can be up to 60V, though it is recommended not to exceed 24V supplies in order to moderate current consumption.

9 Peripheral Components
9.1 GJD Opal Elite Motion Detector
Note that the following instructions are mainly taken directly from the manufacturer‟s instructions. You should refer also to those instructions.
Mount your detector at an appropriate position to cover the area required and ensure that you follow the manufacturer‟s instructions. Route the cable from the shelter/GTT through cable entry gland.
Provide power to the detector‟s + and – connections then connect the +ve to one of the terminals marked CCTV The other terminal marked CCTV should be connected back through connector blocks or cage clamp (see site wiring schematic) and on to the relevant terminal on the GTT. The unit will need to be programmed as per the programming instructions below.
Note that when the detector detects motion, the voltage on the GTT monitoring circuit will drop from the supply voltage to zero volts for a period of 2 seconds. This voltage drop causes the GTT to raise a motion detected alarm.

Table 11 Generator Monitoring Options
Start/stop control may be implemented as follows:
Inhibit starting via a relay in series with the remote start signal and thus the ATS will normally
control the starting sequence and the SiteWatch system provides an override function only.
Integration with a remote/local start/stop switch with a relay controlled by the GTT. If the
start/stop switch provides an absolute override then the generator may be remotely controlled
but the breaker status must be independently managed.
Via a relay driving signal to external start/stop input in generator control circuitry.
Via “Dummy” signal in parallel with ATS start signal, to start generator on demand.
10.1 Running Indicator
Most generator control panels and intelligent controllers offer a voltage-free output running indicator. Voltage free contacts can be monitored by the GTT through connection to either an analogue or digital input.
Page 40 of 81 Version 3.2
In the case of a digital input, connect a DC voltage supply source between 3 and 24V to the running status output and connect back to the GTT digital input. Configure the digital input to be of type latch-low.
In the case of an analogue input, connect a DC voltage source between 3 and 15V to the running status output and connect back to the GTT analogue input. Configure the analogue input to be of type latch-low and set the alarm threshold to be 10V.
10.2 Start Control
Many generator panels support an external start input. Normally, this will be connected to an Automatic Transfer Switch which will pull the circuit to ground when the generator is required to start. Using an appropriate relay configuration, the GTT may be wired in parallel to the ATS to independently control the start function:
Note that whilst it is possible to give general guidelines on how this can be achieved, it is strongly recommended that each case is considered individually in order to consider all the side-effects that may occur in such an arrangement.
Figure 25 Relay Wiring Diagram
The relays normally supplied by Telemisis will be wired as follows:
Version 3.2 Page 41 of 81
Terminal To Description
A1 12V nominal DC supply Connect to site DC power supply fused at 500mA.
A2 GTT Output (daughterboard) Default output circuit is number 5. Output should be set HIGH to activate relay.
11,14 Start Control Circuit closes when relay activates. One end must be wired to Ground
Table 12 Telemisis Supplied Relay Connections
Note that some configurations may allow start control without the need for a relay.
10.3 Start Inhibit
Many generator panels support an external start inhibit. Normally, this will be connected to an emergency stop switch will pull the circuit to ground when the generator is required to start. Using an appropriate relay configuration, the GTT may be wired in parallel to stop switch to independently control the start inhibit function:
Note that whilst it is possible to give general guidelines on how this can be achieved, it is strongly recommended that each case is considered individually in order to consider all the side-effects that may occur in such an arrangement. Refer to the previous instructions on relay configuration and installation.
Note that some configurations may allow start inhibit control without the need for a relay.
10.4 Integration with an FG Wilson Powerwizard 1.0 or Similar Controller
The PW1.0 does not support Modbus remote control and may only therefore be managed via contact based integration. The following set of connections is recommended:
PW 1.0 Interface GTT Interface
Typical Value Description
Genset running indicator. Active High
I/P 1 Inactive < 1V
Active 12-24V
PW1.0 raises dedicated output to voltage high when genset is running
Common generator alarm
I/P 2 Inactive < 1V
Active 12-24V
PW1.0 raises dedicated output to voltage high when any of the common alarms is active
Emergency stop status
I/P 3 Via relay See description below
Remote Start O/P 1 Floating, GTT grounds pin
to start
GTT output is configured for Set High as default. START function in gentrak pulls the output low and the PW1.0 starts the genset
Table 13 PW1.0 Recommended Connections
Note that the PW1.0 must be configured and wired as appropriate to the above functions. Telemisis strongly recommends the use of protected input tails for this application.
Note: a suitable I/O template must be created and assigned to each GTT that is to be installed as above.
Page 42 of 81 Version 3.2
10.4.1 Interfacing with Emergency Stop Circuit
Emergency stop circuits may be wired in one of two ways – Normally Open or Normally Closed. The most common implementation is Normally Closed where a supply voltage is applied to the circuit and the emergency stop button breaks the circuit.
Choose the appropriate implementation from the following options:
1. Direct connection to GTT input set to Latch Low or Latch High setting as appropriate
2. Normally Closed circuit connected via relay where the power from the E-stop circuit maintains the relay in an open state (configuration A). GTT input configured for Latch High setting.
3. Normally Open circuit connected via relay where the power from the activated E-stop circuit closes the relay (configuration B). GTT input configured for Latch High setting.

11 Intelligent Controller installation
If a generator does not have an IC fitted or the fitted IC does not have an RS232 or RS485 data port then call or email Telemisis Technical Support for specific installation instructions.
If an IC compatible with SiteWatch/GenTrak is fitted then connect it to the GTT using the appropriate specialist cable. For a list of compatible controllers refer to the table below.
Ensure that RS232 serial interface types are connected to the GTT RS232 port and that RS485 types are connected to the RS485 port.
Once you have connected the IC and if the GTT has been correctly configured at the server, then the LED code (6) for external device should no longer be active.

11.2 MICS Telys2 Specifics
The Telys2 requires the red (or blue) core from the RS485 port on the GTT to be connected to the A (+) terminal, and the green (or orange) core to be connected to the B (-) terminal.
Note also that the RS485 connection is particularly sensitive to ground differentials. If you can measure more than about 8-10 ohms between the GTT chassis and the Telys2 chassis then you may find that you have communications problems on the RS485 link. This is characterised by streams of FF characters on the Modbus interface and the MB ERR:0 being reported in debug output. To solve this, either ensure that the GTT and the Telys share the same power source or link the chassis grounds of the two devices.
Configure the Telys2 with the following communications parameters: 9600bps, 8 bit, 1 stop bit, no parity, JBUS=1. Set switch marked R31 (terminating resistor) to position = ON.
11.3 DeepSea Specifics
Deepsea panels all require the RTS line from the GTT to be held in a high state i.e. they operate with hardware flow control. Telemisis cables manufactured after April 2009 all have this configuration.
Telemisis provide two types of Deepsea specific cable – standard RS232 serial and a special cable to connect to the Deepsea P810 port. If using the latter then you should be able to connect the cable to any compatible Deepsea controller without the need to perform any further configuration.
Note: Deepsea 72xx controllers do not include Modbus remote operation and cannot therefore be interfaced with GTT units except by means of contact-based I/O.
Standard serial port interfacing requires the Deepsea controller to be correctly configured. Using your Deepsea 5xxx configuration tool (or Link 5000+ for 5500 series) follows the general instructions below:
1. Connect laptop to Deepsea panel and start the configuration software
2. Read current configuration to laptop
3. Select Setup and configure “Remote Control Enable” and “Remote Switching Enable”
4. Enable RS485 and set baud rate to 19200 and Slave ID to 10
5. Select Edit Config tab and set “No Modem”. Confirm that slave ID and baud rate are set correctly
6. Select Setup and deselect “RS485 Enabled”
7. Go to Config Manager tab and select “Write to Controller”
8. For 55xx series panels, power cycle the controller
11.4 Testing the IC
Check that all the expected types of data are being reported to the server.
If possible, generate an alarm from the IC and check that it is reported as expected by text, email and/or to the SiteWatch/GenTrak UI.
Check that the mode change commands and the Start/Stop commands work correctly.

12 Fuel Sensor Installation
12.1 Fuel Sensor Options
Telemisis supplies three types of fuel sensor:
1. Fozmula capacitive with a fixed stem and the electronics on top of the tank
2. Fozmula hydrostatic with a flexible stem and the electronics on top of the tank. Note: there are two types of this sensor and the sensor may be supplied in different lengths and furthermore may be calibrated to different set depths. The calibrated length is marked upon the stem of the sensor with a yellow line, the length being from the end of the sensor head to the yellow line.
3. SensorTechnics (ST) hydrostatic with the electronics in the sensor head
The majority of these instructions relate to all three types of sensor. Where applicable, please refer to the instructions in green relating specifically to the ST sensor type.
You must ensure that the SiteWatch system is configured with the correct sensor type before the GTT auto calibration procedure is carried out or the procedure may fail. If the configuration is automatically setup according to the settings in the Shipped Units then the whole procedure of basic configuration and auto calibration of the unit should be automatic.
The mounting of the SensorTechnics hydrostatic liquid level sensor onto a tank differs to that of the Fozmula TLL range of sensors. Instead of a mounting flange holding the head of the sensor in place in the sensor enclosure, a cable gland is used to support the sensor umbilical from the sensor enclosure into the tank and cable terminations are done with block terminals.
12.1.1 Fozmula Hydrostatic Sensor Types and Lengths
These sensors are supplied in different lengths to suit different tank sizes. It is, however, possible to use a sensor that is longer than the depth of the tank quite effectively since the detector lies at the bottom of the tank and.detects the liquid depth regardless of how much extra cable is installed. What affects the accuracy is the liquid depth to which the sensor is calibrated.
Here are some basic guidelines for use of sensors:
1. It is not a good idea to use a sensor that is shorter than the depth of the tank or calibrated to a shorter depth because the sensor will only be able to measure a proportion of the liquid in the tank.
2. If the sensor is much longer than the depth of the tank then the accuracy will be compromised. It is possible to re-calibrate the sensor to the correct depth but the instructions for this are not included here.
3. Do not press the calibrate button on the top of fuel sensors unless you are sure that you understand the correct procedure. The calibrate button on the sensor is not related to the calibration of the GTT or the sensor connection circuit.
4. Fozmula sensors with a blue calibration button on top are of type “Fozmula 0.5 to 5V”. Because the baseline output voltage of these sensors is 0.5 Volts rather than 0 Volts, sensors of this type will fail auto calibration unless the GTT configuration is correctly set for this type of sensor. Note: do not under any circumstances press and hold the calibrate button.
5. Fozmula sensors supplied after Jan 1st 2010 are of calibrated length 1.8m and are approximately 2.1m long. These sensors output approximately 300mV when in free air. They do NOT have the blue calibrate button.
12.1.2 Identifying Fozmula and SensorTechnics Sensors
The Sensortechnics sensor has all of its components contained in the sensor body. There is no head to the sensor assembly, only open tails for connection of power and signal line.

12.4.2 Server Configuration Before Installation
For new GTT units you must ensure that the correct default data is in place such that when the unit is installed it is configured correctly, especially with respect to the calibration setting.
If you are upgrading a unit on site or replacing a unit, follow the procedure for setting the calibration setting before you carry out the calibration procedure.
12.4.3 Wiring
Between the sensor assembly and the GTT/generator canopy, the following wire cores are required:
Ground. This can be derived from the power supply or any other suitable point that has ground continuity with the GTT. Note that good ground continuity between the GTT/generator canopy and the sensor assembly is essential. Never attempt to connect the ground of the cable at the tank end to the tank itself.
Sensor power supply. This is normally derived from the same power supply that serves the GTT.
Sensor signal, 0-5V output of the fuel sensor
Almost any suitable wire gauge may be utilised but for distances of greater than 10m, heavier wire gauges are highly recommended so that cable losses and effects of temperature variations are minimised.
If the GTT and fuel sensor need to be calibrated on site (this is normally the case), run the wire between the GTT/generator and the fuel tank and leave both ends close to the equipment so that the calibration procedure can be run before the fuel sensor is actually placed in the tank.
12.4.4 On-site Preparation and Planning
Decide where on the tank surface to install the fuel sensor assembly
Plan the routing of the cable between the fuel sensor and the GTT
Page 50 of 81 Version 3.2
Identify where on the tank top the fuel sensor is to be installed and ensure the surface is reasonably clean (unlike our example). Note: it is recommended that fuel sensors are installed at least 20-30 cm away from breather holes and filling apertures and never within 10cm of the edge of a tank.
Figure 30 Complete Installation
12.4.5 Automatic Calibration
The purpose of the calibration procedure is to increase the accuracy of the data derived from the fuel sensor. Refer to section 13 for full details. Before commencing this procedure ensure that the calibration function is turned on for the specific GTT at the SiteWatch server. If you have installed a new GTT then the system may have been configured to automatically turn on calibration. The system LED will be flashing code 5 if calibration mode is on.
12.5 Fozmula Sensors Installation
The following stages may be carried out either before the visit or at the site. However, in preparation for possible poor weather it is normally easier to carry out at least some of these tasks before attending site.
Ream out the flange holes to 6mm.
Version 3.2 Page 51 of 81
Mark and drill the hole for the cable gland on one side of the box. It doesn‟t matter which. Note which step of the drill you need to use (15mm hole) and, if you prefer, mark the depth on the drill using electricians tape.
Box Mounting Method A - Drilling the Mounting Holes in Advance
Mark and drill the ABS box using the 6mm drill and drill the centre hole with the hole-saw. Use the flange or the thin washer as the guide for marking but make sure it’s the right way up as they are not symmetrical.
Alternatively, see method B (recommended) below. Drill only the centre hole and use the flange on site as a guide for drilling the bolt holes. If you are taking this approach, skip the remaining stages of this section except for the drilling of the centre hole.
Check that the flange aligns well the centre hole and the bolt holes. The bolt holes are not symmetrically drilled in the flange so take care with the orientation of the flange.
Page 52 of 81 Version 3.2
Or if you prefer, drill the centre hole first from the rear and then use the flange from the top side of the box for accurate hole marking (unless you are following method B):
12.5.1 Schematic of the Fozmula Sensor
Figure 31 Fuel Sensor Assembly (Fozmula)
To ensure that you are fully aware of the way that the components fit together, study the above diagram and the pictures below and above before making your installation. The pictures are only examples; your wiring within the box and to the GTT may be slightly different.
12.5.2 ABS Box Installation
Here are some points to note before you start:
The flange and gaskets are not symmetrical in terms of the hole positioning. Once you have determined the orientation of the ABS box, it is a good idea to line up all the holes and use a marker pen to indicate the alignment on the box and the components (method B below removes any need for this)
Version 3.2 Page 53 of 81
The installation procedure does not require high tolerance alignment of parts but does require some care to ensure that the assembly is water-tight
When drilling, take care to cover open holes with electrician‟s tape and to blow away swarf before removing the drill from the hole
If you are installing onto a cylindrical tank, the nitrile gasket will make a good seal but you will have to be careful with the alignment of the bolt holes
Whether you use method A or B, the procedure for drilling the centre hole in the tank is the same. Using the punch, make a mark and carefully drill out the 29mm hole. When the hole-saw breaks through the metal plate the circle of metal is normally retained in the hole-saw and will therefore not drop down into the tank. Even if it does drop-down, it doesn‟t really matter. Before pulling out the hole-saw blow the swarf away from the hole.
In the pictures below, the installation has been done in a slightly different order and the pilot holes for the mounting bolts were drilled first. This illustrates that there are many ways to install the mounting box.
Don‟t forget to knock out the circle of metal from inside the hole-saw when you withdraw the saw from the hole.
Method A (Pre-drilled box)
Decide upon the orientation of the box on the top of the tank with respect to the cable outlet. Position the box and mark the positions for the holes on the top of the tank using either a marker pen or a centre-punch and hammer.
Page 54 of 81 Version 3.2
When you are experienced in the installation you can probably drill all the holes at once. However, it is safer to drill the centre hole first as shown above and then double check the positions of the bolts before drilling the 2.5mm bolt pilot holes. Check the positions of the bolt holes by inserting the flange into the box and locating it in the hole in the tank. Don‟t fit the nitrile gasket at this point because the flange won‟t then locate in the hole in the tank. Locating the flange in the tank hole automatically centres the box and enables you to check the positions of the holes.
Cover the centre hole and each pilot hole as you drill them with electrician‟s tape.
Drill each pilot hole and carefully check the alignment using the box or the gasket. It is not essential that the alignment is perfect but generally each hole should be within about 1mm of its intended centre. You don‟t have to drill the pilot holes all the way through the metal. If you do drill through then blow the swarf away before withdrawing the drill.
Line up the flange and the thin gasket and pass two screws through the holes and through the holes in the box. Slide the thick nitrile gasket over the two screws so that the drill tips protrude at least 10mm. Locate the screw tips into their pilot holes and push the box down flush. Using the 8mm boss, drill through the tank and thread the screw 5-10mm further into the tank. Check again the alignment of the centre hole and then repeat for the second hole. If all is well, repeat the process for the other 3 screws and tighten. Do not overtighten as you may strip the thread !
Version 3.2 Page 55 of 81
Method B – Using the Flange as a Guide for Drilling
First, drill the centre hole as shown in the earlier section. Now place the flange and the thin gasket (double the correct alignment of the holes in the flange and gasket) into the box and drop the box and the flange into the hole in the tank so that the box is flush with the surface. Orientate the box as you require and using the 6mm drill, drill through the box and just into the surface of the tank. Do NOT drill all the way through as this will create a hole which is too big for the mounting bolts. This creates a pilot hole that you can use to mount the first of the bolts. Lift up the box and reveal the pilot hole.
Using the 8mm boss, take one of the self-drilling screws and drill down through the pilot hole until the thread of the screw just begins to cut into the surface of the tank. Blow away the swarf taking care to ensure that it does not drop into the large hole (this should have been covered with electrician‟s tape). You can perform this stage with the box still in place if you prefer.
Remove the screw and place through the hole in the box that you just drilled. Take the thick Nitrile gasket and, after first double checking the orientation, finger tighten the screw through the gasket until about 5mm of the screw pokes through. Now replace the box and line up the bolt with its hole. Finger-tighten the screw into its thread.
Double check your alignment of the centre hole – it doesn‟t have to be exactly centred, just ensure that the flange hole is completely clear through. On the opposite side of the box, drill a second 6mm hole just into the surface of the steel. Do NOT drill all the way through as this will create a hole which is too big for the mounting bolts. Using the 8mm boss, take another self-drilling screw and drill down through the pilot hole until the screw bites and screws down. Screw all the way down but do not completely tighten. Tighten up the other screw so that the box is held securely. Tighten to other screw. Blow away the swarf taking care to ensure that it does not drop into the large hole.
Now you can install the other three screws boss directly without the need for pilot holes. Ensure all screws are tight but do not over-tighten as you may strip the thread !

12.5.3 Wiring
If the GTT and fuel sensor need to be calibrated on site, run the wire between the GTT/generator and the fuel tank and leave both ends close to the equipment so that the calibration procedure can be run before the fuel sensor is actually placed in the tank.
Figure 32 Fuel Sensor Connection Diagram (Fozmula)
The yellow cable (low-level alert) may not be needed but it does no harm to connect it to the cable at the sensor end. Refer to separate instructions for connection of fuel low-level alarm from the sensor. Note that the low-level alarm from the sensor is not normally necessary since the software in the GenTrak/SiteWatch server and/or the GTT will generate alarms anyway based upon the level of the fuel reported by the sensor.
12.5.4 Installing the Sensor in the Box
Take the transducer end of the fuel sensor and carefully pass it through the hole in the flange. If you have carried out the calibration procedure then the wiring for the sensor will already be in place. Unclip the Packard connector from the sensor and then screw in the fuel sensor head to the flange until it is finger-tight. Connect the Packard connector to the sensor. Tension the incoming cable as required and tighten the gland until it makes a water tight seal. Loop up the cable inside the box and screw down the box lid.
12.6 SensorTechnics Sensors Installation
Where appropriate, refer also to the instructions above when preparing the box and the tank for installation. Mark the mounting and through hole centres in the middle of the base of the sensor enclosure using the nitrile gasket as a template. Drill out the 5 mounting holes in the plastic enclosure to 6mm diameter. Drill the base centre and the side cable gland mounting hole to 18mm diameter. In the base of the enclosure, 10mm outside of the area covered by the nitrile gasket, drill a fine breather hole of about 1 or 2mm diameter for atmospheric pressure equalisation.

Figure 33: Prepared Enclosure
Locate the mounting point of the sensor enclosure on the tank and mark out the hole centres onto the tank using the sensor enclosure as a template ensuring that the enclosure is orientated correctly for your cable run. Drill the mounting screw pilot holes and cut the central clearance hole into the tank. Fix the cable glands in place, The sensor supporting gland should be fixed such that the fixing nut sits inside the nitrile gasket on the underside of the enclosure.
Figure 34: Base Underside / Gland Nut
Pass the sensor umbilical up through the cable gland in the base of the enclosure, leaving approximately 200mm including the wire tails inside the plastic enclosure. Tighten the gland so that the cable is firmly held BEFORE proceeding to the next stage
Feed the cross-site cable through the side gland and terminate to the sensor tails using the terminal blocks supplied. Do not tighten the gland yet and do not insert the fuel sensor into the tank. Wire terminations are as follows-:
a. Sensor End i. Red = VDC “+ve” (7 to 30 Volts DC) ii. Black = Ground iii. Yellow = Sensor Signal
b. GTT End i. From fuel sensor Red, connect the appropriate cross-site colour to the power supply.

iii. From fuel sensor Yellow, connect the appropriate cross-site colour to the GTT Analogue input #3 (colour grey). (Assigned by GTT mapping template)
Figure 35: Sensor wire tails and breather tube.
Figure 36: Sensor Tail Terminations
If you are installing the fuel sensor on a new site with a new Telemisis GTT, the SiteWatch system will automatically detect the fuel sensor type during the calibration stage of the operation. Once the calibration stage is complete you may proceed with the sensor installation. Refer to separate instructions in the Telemisis Installation Guide to help you identify the end of the calibration stage.
Now feed the fuel sensor head carefully into the tank until you feel it touch the bottom.
Secure the box to the tank, tighten the side gland and install the lid securely.
If possible, check and note the time and the tank fuel level from the sight gauge and confirm either by telephone or by internet access or at a later time that the correct fuel level is being reported by SiteWatch.
Version 3.2 Page 59 of 81
Special Note
Alongside the wire tails is a pressure equalising tube with filter attached, this permits the sensor to adjust readings by compensating for atmospheric pressure variances. If the sensor is installed in an airtight environment then automatic adjustment cannot take place so a breather hole should be drilled in the mounting enclosure as described in the instructions above. Note also that during installation you should take care not to dislodge the filter or to pinch or kink the breather tube.
N.B.in the future, to remove the sensor fully from the tank the enclosure will have to be unscrewed from the tank top.
12.6.1 Wiring
Between the sensor assembly and the GTT/generator canopy, the following wire cores are required:
Ground. This can be derived from the power supply or any other suitable point that has ground continuity with the GTT. Note that good ground continuity between the GTT/generator canopy and the sensor assembly is essential. Never attempt to connect the ground of the cable at the tank end to the tank itself.
Sensor power supply. This is normally derived from the same power supply that serves the GTT.
Sensor signal, 0.5-5V output of the fuel sensor
Almost any suitable wire gauge may be utilised but for distances of greater than 10m, heavier wire gauges are highly recommended so that cable losses and effects of temperature variations are minimised.
Figure 37 Fuel Sensor Connection Diagram (ST)
12.7 Connecting up the GTT End
If you have carried out the calibration procedure then the GTT end will already be connected. If not, simply wire up the GTT end as shown in the calibration procedure.
12.8 Testing
Ensure that the unit‟s configuration at the server is complete in respect of the assignment of a generator type and a fuel tank.
Check that the fuel reading in terms of percentage and actual volume is consistent with the actual volume of fuel in the tank.

12.9 Fuel Sensor Reset Function
Under some circumstances it may be desirable for the SiteWatch system to be able to execute a power reset of the fuel sensor. This is achieved by wiring the ground line of the fuel sensor directly to one of the GTT rugged digital outputs. The state of that output should then be configured for Set Low in normal circumstances. Changing the state to Set High will remove the power source to the sensor and changing it back to Set Low will reconnect the power. Please follow your specific site wiring configuration for this feature.
Version 3.2 Page 61 of 81
13 GTT and Fuel Sensor Calibration
The calibration procedure characterises several aspects of the specific installation. The final result is that data from the sensor is adjusted according to the following characteristics:
Minor differences between the output of the sensor and the expected output
The cable loss between the sensor and the GTT
Minor differences in the GTT circuitry
The procedure is automated except for, potentially, the need to wire up a special loom at the GTT end of the connection for a short period. On some sites with specific configurations, the normal wiring configuration may be correct for the calibration procedure.
For auto calibration to operate without intervention from the system operator the following prerequisites should be complete.
All units expected to auto calibrate should have their details entered into the Shipped Units table
In the shipped units table, the entries should have the Auto Calibrate criteria set ON so that on initial connection the settings are uploaded
Telemisis will normally ensure that these settings have been correctly established.
13.1 Sensor End
Before the calibration procedure can operate successfully the fuel sensor must be out of the fuel tank and be reporting a zero liquid level. Note: zero signal level does not necessarily mean zero volts as some sensors report a positive voltage for an empty tank. The important issue is that the sensor must be reporting the expected voltage for an empty tank.
Pass the end of the connecting wire through the gland but do not yet tighten the gland. Designate the colours of the wire to the colours of the Packard connector assembly:
Where at the sensor end of the assembly:
RED = power
BLACK = ground
GREEN = sensor output (Fozmula) or YELLOW (ST)
Connect the fuel sensor to the assembly but do not mount the sensor into the tank.
13.2 GTT End
Before proceeding, check that the automated calibration procedure is active. If the ARM LED is flashing code 5 then the procedure is active.
Page 62 of 81 Version 3.2
Option 1: If the site wiring configuration already takes into account the requirements of calibration then the calibration procedure may be automatically completed as soon as the GTT connects to the SiteWatch server.

The wiring at the GTT end (see above) for the calibration is as follows. In addition to the connections shown, wire in the 12VDC supply to the 12V connection of the connector block.
Pin Screw terminal Purpose Wired to
Ana 1 Blue 1 Ground reference IN Ground of outputs and ground of sensor cable
Ana 2 Brown 2 3.3V reference IN Output 3
Ana 3,4 Black 1 Ground Ground connectors in block
Ana 5 Grey 3 Power supply monitor IN 12V supply and TO sensor power
Ana 6 Green 4 Sensor output IN FROM Sensor output
Oput 1, 2 Black 1 Ground Ground connectors in block
Oput 3 Blue 2 3.3V OUT Analogue 2
Table 19 Fuel Sensor Connections Block – Option 2
13.3 Testing
Using a multi-meter at the GTT end connector block, check the voltages between ground (screw terminal 1), 3.3V reference (screw terminal 2), 12V supply (screw terminal 3) and the sensor output. They should be in the following ranges:
Version 3.2 Page 63 of 81
Purpose Voltage Range
3.3V reference 3.2 to 3.4V
12V supply 11-15V
Sensor output 0-100mV1 or
40-550
Table 20 Testing Interface Voltages
If any are out of range then double-check your wiring.
If all is well then within a few minutes the calibration procedure should be complete and code 5 will no longer flash on the ARM LED.
If you are able to access the SiteWatch/GenTrak server, check the settings in the Unit Configuration for Calibration Factor and Offset and the Calibration flag. If calibration has been carried out successfully then at least one of the Factor and Offset should be different to the defaults (1000, 0) and the calibration setting should be “Calibrated”.
Also check that a fuel tank instance has been created or was already defined. No fuel readings will be displayed or collected by the system unless a valid fuel tank record is in place
13.4 What to do if Calibration Does Not Complete
Take accurate readings from your multi-meter as above and note them down. Later they can be entered into a spreadsheet and the calibration settings can be entered manually.

14 Site Batteries Cycling
Battery cycling capability is built into the firmware release of the GTT and therefore you must ensure that the correct version of firmware is installed. Refer to Appendix C – GTT Firmware Options.
Battery cycling works effectively by preventing the generator from running when the site batteries are capable of delivering power to the site. The generator control panel must be set so that the normal generator operation is not affected if the GTT or any of the wiring fails. Hence, the Generator Inhibit function must be set so that the starting is inhibited when the GTT raises the voltage on the line. Associated with the cycling activity is an IO Mapping Template. This template must be consistent with the configuration of the charging data configuration in the SiteWatch Server. In particular, the Digital Output number of the Generator Inhibit function must be defined, the Digital Input number to detect whether the Generator is running, low and high battery indications and low and high temperature indications (if required). Default configuration is as follows and you should ensure that the GTT is wired appropriately:
Purpose Default State GTT Interface
Start Inhibit Low = not inhibit Output 5
Gen Running Low = Not Running Input 5
Batteries High Not currently supported -
Batteries Low Not currently supported -
Temperature High Low = not activated (default OFF) Input 8
Battery Temp High Low = not activated (default OFF) Input 9
Over-temp Low = not activated (default OFF) Input 10
Table 21 Battery Charging Inputs and Outputs
Battery level indications are normally provided by relay outputs from devices which trigger high when the external voltage condition is matched.

19 Appendix B – System LED Error Codes
The lowest numbered, that is the most important, active code is shown on the STAT LED.
If you view the unit debug then all of the active error codes are shown in the STS ERR message that is displayed every few minutes e.g. STS ERR 4,8 means that code 4 and 8 are active..
Error codes are represented as follows:
1. LED off for 3 seconds
2. The Error code is represented by the LED flashing on/off at one second intervals a number of times.
STAT LED Sequence Meaning
On and off for 4 seconds The processor is booting.
Two flashes and off for 2 seconds
The Asset service switch is on the ON position.
ERROR CODE 1
On one second
Off one second
Off for 3 seconds
Approximately 2 minutes after power-up if the LED flashes sequentially on for 1 second and then turns off for 3 seconds then the cellular module has been unable to register with the GSM network. This could be because no SIM is inserted, the SIM is inserted incorrectly, the SIM is damaged, the SIM is invalid, there is a PIN security code configured in the SIM or there is no or inadequate network signal. Try the SIM in a mobile „phone to establish the cause of the problem and if necessary disable the PIN security code.
ERROR CODE 2
On / Off Twice
Then
Off for 3 seconds
The unit is communicating with the mobile „phone network but it cannot send a text message to the registration server. Note that this code is irrelevant to units which have not been loaded with a registration firmware build. Try sending the message text message “TEST” (without the quotes) to your registration server (default +447833256997 although you may have been given an alternative number in your own country). If it is not possible to send that message or you do not get a text message (“OK”) response from the registration server then possible causes include: Temporary network problem, SMS sending not enabled in network for the SIM subscription, international access not enabled for the SIM. Contact your support representative if you cannot resolve this problem.
ERROR CODE 3
The unit has been able to send the registration SMS message but a response has not been received from the registration server. If this condition persists then contact your support representative.
ERROR CODE 4
The unit has registered with the registration server but it cannot establish an active communication with its designated SiteWatch server. This could be because: the SIM is not enabled for GPRS service, the APN data provided by the registration server is incorrect, the required TCP port is blocked in the network by a firewall or there is a temporary network problem.
ERROR CODE 5
The automated calibration procedure has not been completed. If calibration is not required, ensure that the calibration flag is set to OFF or CALIBRATED in the unit configuration. Otherwise, you must ensure that the correct calibration voltages are being applied to the correct analogue interfaces on the GTT. Refer to your site schematics or other wiring instructions.
ERROR CODE 6
External communications failure or failure of connected device e.g. no response received from generator IC.
ERROR CODE 7
Internal communications problem lost between ARM microprocessor and the cellular engine. This code will occur after the GTT unit starts up and will display for a short period of time while the GTT tries establishes internal connection. If the communications fails then the code 7 will be replaced by code 3 or 4.
ERROR CODE 8
Hardware problem detected e.g. GPS chip not responding or no GPS Lock, ARM microprocessor not responding
