1 Important safety instructions

In addition to the instructions contained in these operating instructions please payattention to universal safety and accident prevention regulations.

The TECHNOVAR drive head must be disconnected from the power supply before any workcan be carried out in the electrical or mechanical part of the system.Installation, maintenance and repair work may only be carried out by trained, skilled andqualified personnel.Unauthorized modifications or changes to the system make all guarantees null and void.When in operation, the motor can be stopped by remote control, whereby the drive head andthe motor remain under voltage. For safety reasons, the unit has to be disconnected from thepower supply when carrying out work on the machinery as locking out the equipment byswitching off the release mechanism or set value cannot prevent accidental starting of themotor.

When the drive head is connected to power supply, the components of thepower unit as well as certain components of the master control unit are alsoconnected to the power supply.

Touching these components seriously endangers life !

Before removing the frequency inverter cover the system must bedisconnected from the power supply. After switching off the power supplywait at least 5 minutes before starting work on or in the TECHNOVAR drivehead (the capacitors in the intermediate circuit have to be discharged by theinstalled discharge resistors first).

Voltages of up to 800 volts are possible (if there are faults it can be higher)

All work, carried out when the frequency inverter is open, may only beperformed by qualified authorized staff.

Furthermore, care must be taken not to short circuit the neighbouringcomponents when connecting the external control wires and that opencable ends which are not in use are isolated.


6

The TECHNOVAR drive head contains electronic safety devices whichswitch off the control element in the event of faults, whereby themotor has zero current but remains energized and comes to a halt. Themotor can also be halted by mechanical blocking. If it is switched offelectronically the motor is disconnected from the mains voltagethrough the electronics of the frequency converter but is not potential-free in the circuit.In addition voltage fluctuations, especially power failures can cause thesystem to switch off itself.

The system may only be put into operation when it has been earthened. In addition,equipotential bonding of all pipes must be ensured.

Warns that failure to observe the precautions may cause electrical shock.Failure to follow these instructions could result in serious personal injury or death.

Warns that failure to follow these instructions could result in serious personalinjury or death as well as property damage.

Repair of faults can cause the motor to start up again!

2 System Design

The following diagrams show typical single pump and multi-pump systems using theTechnovar control unit. Connection can be made directly to a water supply or water can bedrawn from a break tank or well. In the case of break tanks and wells, level switches, shouldbe used to shut down the pumps when water is low. In the direct connection, a pressureswitch on the suction side should be used.

3 Pressure tank

A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintainpressure in the line when there is no demand. This will keep the pumps from continuing torun. With the Technovar control unit, it is not necessary to have a large tank for supplypurposes.In selecting a tank, make sure it is permit and suitable for systems pressure. The tank shouldhave a capacity of more than 10% of the maximum system flow rate g/min of one pump (alsoin a multiple pump system!).

Pre charge the tank to the following:

Required pressure

Note: De-pressurize the tank prior to charging to ensure accuracy of thepre-charged pressure.

8.3 Single Pump – Pump Protection

The Technovar has the ability to protect the pump by shutting off in low/no suction or run outconditions.

Note: Low/no suction protection depends on the installation of a suction linepressure switch, or float switch for a tank. This switch is connected tothe Technovar. The cut out setting for a suction pressure switch shouldbe greater than the minimum incoming pressure, required by the pump.

Note: Run out protection is available for one pump systems and multiple pumpsystems with a common suction pipe. (described at chapter ”ConveyorLimit” 11.30.1 In multiple pump systems with separate suction pipes,you can not avoid dry running by measuring the system pressure,because the pressure is produced from another pump in the system.

8.3.1 To set run out protection

Hold the button for 3 seconds and the display changes to PASSWORD0000

Password:The password protection prevents untrained personal from accidentally changing of the basesettings:

Set ‘Password 0066’ by pressing or PASSWORD0066

You will now be able to access all of the alternate menus for all Technovar optional controls.

After entering the password you have to confirm by pressingthe button to advance the display to the next window

JOG – MODE0.0 Hz X.XX psi

JOG-MODEActual outgoing frequency and actual analog input are shown. By pressing or in thismenu, the internal controller of the Technovar will be shut off and the inverter changes tomanual mode. With the buttons and you can set any constant speed. Setting of 0,0 Hzstops the inverter. If the JOG-MODE is left at a frequency higher than 0,0 Hz the inverter willcontinue its normal automatic operation.

Press the button repeatedly until you reach SUBMENUERRORS

Hold the button down for 3 seconds to enter thesubmenu, until the display changes to

If this value is not reached, the failure “CONVEYOR CONTROL ERROR” will be indicated andthe pump will stop.

Press once the button and change to DELAY TIME2 Sec.

DELAY TIMEThe delay time is adjustable between 0 and 100 Sec. for switch-off of the Technovar in case of lowwater, (Terminal X1/6-X1/7) and conveyor limit.

Press to advance the display to ERROR-RESETdisabled

ERROR-RESETif you want to have an automatic error reset for 5 times (not for errors in the control-port),you have to set a delay time for the automatic reset (range: 0-250 sec.).That means after a non fatal error, the Technovar will be restarted after the set delay time.After five consecutive errors the converter switches off.To disable this function press until “disabled” appears. (The internal counter of the automatic resets will be reduced by one each operating hour).

Note: “Fatal” errors will always shut down the system at the first time.

Hold down the key for 3 sec. to leave the submenu andthe display changes to

8.4 Single Pump – System Curve Compensation

The Technovar can automatically compensate for system friction losses due to increased flow.Tables are available in most pump catalogs, indicating the amount of friction losses that canbe expected in various sizes of pipes at different flow rates. Use these tables to determine thefriction losses for the pipe size you are using at maximum flow rate.This Diagram shows a typical system curve. The system pressure set point is shown at shutoffand pressure increase is shown for increasing flow.Calculate the pressure required to overcome friction losses at maximum flow.

8.5 Multiple Pump - Constant Pressure and System Curve Compensation

When two, three or four Technovar controlled pumps are connected in a system, they can beprogrammed to work together to maintain system pressure up to the maximum flow rate ofall pumps combined. As the first pump reaches its maximum speed and flow, the second willautomatically turn on (and so on). In addition, the sequence of the pump that will run first(lead pump) can be automatically varied to reduce premature wear of any pump in thesystem.



Set ‘Password 0066’ by pressing or . PASSWORD0066


Press the button repeatedly until you reach MODE:Controller

Use and to change the setting to: MODE:Multicontroller

MODE:Controller:If only one TECHNOVAR pump is in operation set the Controller for a stand alone controllerfunction. If more than one pump are working together, connected via the RS485 interface(follow-up pump control), the Multicontroller must be set with the buttons or .Synch. Controller:The Synchronous Controller mode is working in the same way like the Multicontroller. Theonly difference is, that all pumps in the multi pump system are running at the samefrequency.Actuator:The Actuator application is only used if you have an external controller and the Technovar isused as a standard frequency converter. In the Actuator-Mode, the internal controller is shutoff, and the output frequency is proportional to the input signal (X1/2) � 4-20 mA = 0 -fmax. The frequency changes with the programmed ramps 1 and 2. The functions of lowwater, thermal protection and external ON/OFF are still working.


39

...... = fmax

If Manual control is selected, the parameter REQUIRED VALUE will change to Manualcontrol LOCAL, where the actual frequency and the actual value is displayed (according tothe JOG-MODE in the submenu).Now the frequency can be changed with the and buttons, and the speed of the pumpwill change with the fasten ramps1 and 2. After selecting the right frequency, it can besaved with the standard SAVE-parameter.After a supply failure, the pump will then run with this selected frequency (depending onthe parameter AUTO-START).

In the first window, the actual frequency is displayed. The frequency can be changedbetween the set minimum and maximum frequency. (CONFIG. FMIN is not active in thismode!).

Attention Driving the pump in a not allowed speed range can damage the motor or theTechnovar-head!

Press the button five times and you reach SUBMENUSeq. Control

Hold down the button for 3 seconds until the displaychanges to

ACTU. VALUE INC.5 psi

ACTUAL PRESSURE INCREASE (=LIFT VALUE):This value, together with the fall value (ACTUAL VALUE DECREASE) determines theincrease of the required value after starting of the following pumps (see example)


40

Generally a slight pressure drop is allowed on the first pump before the next is started.This allows for brief systems fluctuations without pump cycling. Once the next pumpstarts, however, you will want the system to resume its normal set pressure.

To do this, enter the amount of pressure drop you willallow before the next pump starts (= value ofparameter ACTUAL VALUE DECREASE). The diagramshows the pressure drop and increase.

To increase the pressure even more to compensate forsystem loss at higher flows, enter the total of thesystem drop allowed before next pump starts and theincreased pressure (ACTUAL VALUE INCREASE) desired.

Application example:1) Pump 1 reaches the speed of ENABLE SEQ: CONTROL or more2) Pressure falls and reaches the start-value of the 2nd pump

(= REQUIRED VALUE – ACTUAL VALUE DECREASE)3) Pump 2 is switched on automatically4) The required value is calculated new, after the start of the 2nd pump in the following

way!

New required value = REQUIRED VALUE – ACTUAL VALUE DECREASE + ACTUAL VALUE INCREASE

Generally:k ... Number of active pumpsP = Pset + (k-1)*[lift value – fall value]

� Lift value = Fall value � Pressure constant when pumps switch on� Lift value > Fall value � Pressure rises when lag-pump switches on� Lift value < Fall value � Pressure falls when lag-pump switches on

Enter the required value by pressing the and button ACTU. VALUE INC.7,1 psi

Press the button to confirm and change to ACTU. VALUE DEC.2,1 psi

ACTUAL PRESSURE DECREASE (= Fall value):This value determines amount of pressure drop you willallow before the next pump starts.


41

Enter the required value by pressing the and button ACTU. VALUE DEC.5 psi

Press the button to change to ENABLE SEQ. CTL58.0 Hz

ENABLE SEQUENCE CONTROL: (Release frequenz)The follow-up pump only starts, when the start-value (SET VALUE – ACTUAL VALUEDECREASE) is reached and the lead pump has reached the programmed release-frequency.(Adjustable from 0.0 Hz to 70 Hz).Normally this start frequency is set 1 to 2 Hz lower than the MAX. FREQUENCY If you don’twant to start a following pump this value has to be set higher than the MAX. FREQUENCY.

Enter the required value by pressing the and button ENABLE SEQ. CONTROL59.0 Hz

Note: In the standard multicontroller mode, the next pump will not start until both thesystem pressure drop and release frequency first pump speed have been reached.In the synchronous control mode, the first pump only has to reach the releasefrequency, then the next pump will start.

Press button briefly to advance to SWITCH INTERVAL12 hours

Programming Sequential Operations

Up to four pumps can be connected using the integrated RS-485 interface (Connection of theterminals /1, /2 and /3 of the terminal blocks X5 or X6 of each pump together). However, thefollowing additional programming must be carried out in the submenu:


55

Press for about 3 seconds to enter the submenu and the display changes to

10.22.1 Lift Value


Adjustable between 0.0 to the pre-selectedSensor range

Application Example:1) Pump 1 reaches fmax (maximum speed)2) Pressure falls and reaches the start-value of the 2nd pump

(= REQUIRED VALUE – ACTU. VALUE DEC.)3) Pump 2 is switched on automatically4) The required value is calculated new, after the start of the 2nd pump in the following

way!

New required value = REQUIRED VALUE – ACTU. VALUE DEC. + ACU. VALUE INC.

Generally:k ... Number of active pumps (k >1)p = pset + (k-1)*[lift value – fall value]

� Lift value = Fall value � Pressure constant when pumps switch on� Lift value > Fall value � Pressure rises when lag-pump switches on� Lift value < Fall value � Pressure falls when lag-pump switches on


10.22.2 Fall Value

For calculation of the set pressure after start of pumps 2 to 4

ACTU. VALUE DEC.2.1 psi

Adjustable from 0,0 to pre-selected Sensor rangedetermines the start-value of the 2nd pump and the


56

other following pumps. (Start-Value = REQUIRED VALUE –ACT. VALUE DEC.)


10.22.3 Release frequency of the following controller

ENABLE SEQ. CTL.58.0 Hz

Release of the follow-up pump only when the start-value is reached and the lead pump

has reached the programmed frequency. (Adjustable from 0.0 Hz to 70 Hz).If you do not want to start a following pump this value has to be set higher than themaximum frequency.This parameter is also used to start a constant speed pump, when Simple Multicontr. isset). When this frequency level is reached, the potential free contact of the relay X2/5 –X2/6 will be closed.


10.22.4 Switch Interval

SWITCH INTERVAL12 hours

for changing the master pump and follow-up pump inorder to achieve even operating hours of the pumps

Adjustable between 1 hour and 100 hours. If it is set higher than 100 hours, the automaticchangeover is deactivated).Manual change of master pump in the 1st display with the -button.



57

10.22.5 Source of required value

SOURCE REQ. VALUEOFF

for selecting the address of the source of therequired value. Five adjustments are possible:

OFF, ADR1,ADR2, ADR3 and ADR4. If an additional (INT or EXT-ADC-I or EXT-ADC-U) inputis active, you must enter here the address where this input is connected.At active Multicontroller or Synch. Controller there is shown the active value in a bracket inthe middle of the display. If the sign “#” is shown in the second line of the display, the pumpwill work with a required value from a other pump in the multipump system. On the pump,which is the source of the required value, there is no “#” shown.


10.22.6 Synchronous Control

If the synchronous control is active the activated pumps try to regulate the set pressuretogether (all pumps run at the same frequency). The 2nd pump starts, when the 1st pumpreaches the release frequency (ENABLE SEQ: CONTR) The pumps will now attempt tomaintain pressure by running synchronously. The follow-up pump will than be stopped,when both pump together run below the set SYNCHRON. LIMIT. This creates the hysteresiseffect.

S U B M E N USynch. Control


10.22.6.1 Synchronous Limit

SYNCHRON. LIMIT0,0 Hz

Frequency threshold adjustable between 0,0 Hz andthe set maximum frequency.

Switch off threshold of the first follow-up pump. The switch off thresholds of the otherpumps are each higher by the SYNCHRON-WINDOW.This parameter is also used for the stop value for the external constant speed pump atactivated Simple Multicontroller in the parameter configuration relay.


10.22.6.2 Synchronous Window
