MBBV

MBBV is a plenum box with integrated volume flow regu-lator used for VAV regulation of supply air diffusers. MBBV is equipped with a unique lin-ear cone damper technology which makes it possible to regulate in the full operational area 0-100% up to 200 pa with low sound level.

The built-in VAV actuator is delivered pre-programmed with damper characteristic and in combination with a sta-ble flow measurement over the damper, it makes the VAV regulation very accurate and reliable.

In Pascal system MBBV is controlled by a Regula Combi room controller where all room settings is to be done after installation. This means that no factory settings or specific room labeling is needed for MBBV.

MBBV must be used in combination with a suitable dif-fuser that can handle low airflows, in Pascal system this is LCP, LKP or LCC.

These diffusers also comes with integrated Presence sensor versions and are called LCP-P LKP-P or LCC-P.

MBBV is as standard delivered with a special designed Regula Connect card, for easy and simple wiring.

• Plenum box with integrated volume flow regulator

• Accurate and reliable VAV regulation

• Large operational area 0-100%

• Up to 200 pa with low sound level

• Settings to be done in Regula Combi after installation

• Includes Regula Connect for easy wiring

The MBBV comes with an detachable motorized damper unit.

Regula Connect Pascal

Regula Connect Pascal makes it easy to connect the func-tionalities regarding the MBBV box and Regula Combi pro-grammed as a SRC. Regula Connect Pascal is a connec-tion hub on the MBBV box where input/output for regula-tion, sensors and supply will be connected. For all low cur-rency signals Regula Connect Pascal has interfaces with RJ-standard connectors and for high currency, sensors, supply and supply linking it has PCB connectors from Weidmüller.

From Regula Connect Pascal which is placed on the side of MBBV there is easy connection to room regula-tor Regula Combi, presence sensor via Regula Convert, CO2 relay sensor, heating actuator and of course cooling signal to the volumeflow regulator in MBBV.

Regula Connect Pascal is equipped with Weidmuller SL 3.5 male connectors for 24 V AC supply, sensors and actuators, and 8 pin RJ45 ( 8P8C ) female connectors for signals.

Regula Connect Pascal must be supplied from 24 V AC transformator with 2-wire cable connected into a Wei-dmuller BLZF 3.5 or BL 3.5 female plug that fits the Wei-dmuller SL 3.5/90 male connector on Regula Connect Pascal.

The 24 V AC supply can be linked to other MBBV boxes with Regula Connect Pascal by 2-wire cable via Wei-dmuller BLZF 3.5 or BL 3.5 female plugs.

Sensors and actuators is likewise connected with either Weidmuller BLZF 3.5 or BL 3.5 female plugs.

24 V AC supply to Regula Combi together with all signals to and from Regula Combi is managed via a RJ45 female plug on Regula Connect Pascal together with a RJ45 straight through patch cable.

Signals ( and not 24 V AC supply ) can be linked to other MBBV boxes with Regula Connect Pascal by additional RJ45 female plugs and RJ45 patch cables to other MBBV with Regula Connect Pascal.

The Regula Connect Pascal comes with bracket so it can be installed without the use of tools.

See the wiring and trouble shooting chapter for detailed instructions before connecting your Pascal system.

Lindab recommends “strips” to secure cables.

VRU-MF

VRU-MF is a circular vol-ume flow regulator for VAV regulation in duct systems. VRU-MF consist of a measuring unit and a damper.

The unit is equipped with a compact Belimo motor with D3 sensor technology, which makes it possible to regu-late in a large operational area.

In Pascal systems VRU-MF is primarily used for exhaust control, controlled by a Regula Combi with special de-signed exhaust program.

VRU-MF can also be used for supply regulation as an alternative to MBBV boxes, typically in large open offices or other rooms with a large number of supply diffusers.

VRU-MF needs a certain distance of straight duct before the unit and this has to be observed to obtain a stable and accurate airflow regulation.

Regula Convert

Regula Convert is a unit that translates the presence sensor signal to a relay signal which can be registrered in Regula Combi.

The presence sensor is con-nected to Regula Convert with a 4-wire cable with RJ10 plug.

The connection between Regula Convert and Regula Connect Pascal is also done with a 4-wire cable with RJ11 ( 6P4C ) plug from Regula Convert to a Weidmuller BLZF 3.5 or BL 3.5 female plug that fits to the Weidmuller SL 3.5 male connector on Regula Connect Pascal.

Regula Convert and the presence sensor are supplied with power from Regula Connect. There is a green light diode that indicates if power is connected to Regula Convert.

Regula Master PascalRegula Master

( Ver. 1.0-1-08 )

Regula Master is a small and compact preprogrammed con-troller with internal display. The display is backlit and the menus are easy accessible and controlled by pushbuttons on the front together with two LED indicators for alarm and write indication.

The controller has 2 ports for EXOline communication via RS485 and has digital and analog I/O´s .

The software in Regula Master is specially designed for the Pascal system, and contains three different set up configurations in the same standard unit:

Single Regula Master ( SRM ),

Local Regula Master ( LRM ),

and Global Regula Master ( GRM ).

Exhaust Control

Regula Masters has a built in Exhaust Control function. The procedure of the function is rather simple. Created ( defined ) Supply RCs are connected to a created ( de-fined ) Exhaust RC.

The function adds together the airflow from the SRCs con-nected to the same ERC, and sends the request of total summed airflow to the Exhaust RC which controls the Ex-haust volume flow damper.

There is also an option to add a Constant Flow, ( posi-tive or negative ), to the sum of total airflow, as well as a Flow Factor can be applied on the sum of total air-flow in case where more ( or less ) exhaust is needed. ( Flow factor = Exhaust/Supply, default 1.00 ).

Optimizer function

Fan Optimizing function is performed by GRM or SRM, and runs automatically as soon as the system is defined in Regula Master/s.

Damper position is read from all Regula Combi via Exoline by LRM and further by GRM.

The Fan Optimizing function compares damper positions and regulates the fan output so the value of the damper that is most open at the actual moment is equal to the setpoint value, which can be defined ( default value 85% ).

Fan Optimizing function is one of the features that con-tributes mostly when it comes to energy savings in HVAC systems.

( Regulation parameters, p-band and I-time are set per de-fault, but can be changed if it is necessary. Note, this can cause system to become instable. )

Operating Control

Regula Master has operational control, which is per-formed when the unit is configured as either LRM or SRM.

• Regula Master is monitoring SRC damper behavior in the system

• Indicates alarm if a SRC damper does not move over time

• Indicates alarm if communication with Regula Combi is lost

Inspection mode

Function in LRM used to change mode in all SRC at once for inspection and control measuring in a chosen time period ( default 240 min ). The following modes can be used:

Bypass - AirflowMax

Occupied - flows between AirflowMinOcc and Airflow-MaxOcc depending on actual room temperature and Basic cooling setpoint ( default 22°C ) + setpoint offset

Unoccupied - AirflowMinOcc, as long as actual room temperature is between heating setpoint at unoccupied ( default 15°C ) and cooling setpointvat unoccupied ( default 30°C ).

Standby - flows between AirflowStandby and Airflow-MaxOcc, depending on actual room temperature and Basic cooling setpoint ( default 22°C ) + Neutral zone at Standby ( default 2°C ).

Off - closed damper ( leakage flow ).

The SRC´s will automatically change back to their indi-vidual original mode after 4 hours ( adjustable ).

Pressure limitation

An optional safety function in GRM / SRM to prevent that the system pressure exceeds 200 Pa ( adjustable ) in the supply and exhaust ducts. External pressure sensors for supply and exhaust are connected to GRM / SRM. Use pressure sensors with 0-10 V output.

The pressure control and the analog inputs AI3 and AI4 are activated in the menu:

System -> Pressure control -> SAF and EAF

Typically used when the AHU has extra capacity and a pressure limitation function is not included in the AHU controller.

Alarms and handling

In Regula Master there is a menu item called Alarm Events, where the alarms are listed.

If an alarm condition occurs the Alarm LED on the front panel will start flashing. The LED will continue to flash as long as there are unacknowledged alarms.

Alarms are logged in the alarm list. The list shows type of alarm, date and time for the alarm.

To access the alarm list, press the alarm button, the front panel button with the red button-top.

If there are multiple alarms, this is indicated by up / down arrow symbols at the right-hand edge of the display.

Use the UP and DOWN buttons to access the other alarms.

At the left end of the bottom display line the alarm status is shown. For active, unacknowledged alarms the space is blank. For alarms that have cancelled the text: “can-celled” is shown. Acknowledged, still active or blocked alarms are indicated by Acknowledged or Blocked.

Alarms are acknowledged by pressing the OK button. You are then given the choice of acknowledging the alarm or blocking the alarm.

Acknowledged alarms will remain on the alarm-list until the alarm input signal is cancelled.

Blocked alarms remain on the alarm list until the alarm is cancelled and the block has been removed.

New alarms of the same type will not be activated as long as the block remains.

Since blocking alarms can be potentially hazardous, you need a high log on authority to block alarms.

Regula Master PascalOutdoor air cooling

If the Air Handling Unit does not have a cooling battery there is risk that the AHU cannot deliver cold air in the supply ducts to the rooms in hot summer days when out-door temperature is higher than indoor temperature. To prevent unnecessary overheating of rooms the Outdoor air cooling function can be activated.

In case the outdoor temperature is higher than the room temperature the LRM/SRM will automaticly change the Basic cooling temperature setpoint, and thus making sure that all SRC regulates to AirflowMinOcc. This con-trol is made once every hour ( at hour change ).

If a CO2 relay sensor is connected to SRC and the CO2

switching on level is exceeded, then the airflow can still raise to AirflowMaxOcc.

The Outdoor air cooling function is performed by LRM/SRM, and a duct temperature sensor ( PT1000 in supply duct ) is connected to the LRM/SRM.

However in a system with GRM and two or more LRM it is possible to connect the duct temperature sensor to the GRM instead, using only one central sensor. The central duct temperature connected to GRM is then transmitted to all LRM.

When outdoor air cooling is used, all SRC connected to same LRM/SRM must have the same Basic cooling tem-perature setpoint ( default 22° ).

Night Cooling

Night Cooling function is a way of cooling down the build-ing with cold outdoor air in night time, to save energy for cooling during day time.

It is the AHU controller or BMS system that activates and controls the Night Cooling function in the Pascal system.

The GRM/SRM must receive a digital signal, ( at DI2 ), from AHU controller or BMS to activate the Night Cool-ing function and then GRM/SRM will change mode in all SRC to Unoccupied and the cooling setpoint at Unoc-cupied in all SRC to 17° ( adjustable ).

This is done to make sure the supply dampers will open to AirflowMax initially, but subsequently to regulate the cooling in each room and to obtain the full optimizer function.

Global Regula Masters in cascade

In larger systems that would include more Global Regula Masters ( GRM ), it is desirable that the Fan Optimizing Function is including the whole system.

The Fan Optimizing function is prepared for such occa-sions, providing a possibility to connect several GRMs in a cascade.

Every GRM passes on the highest actual damper posi-tions on AO3 ( SRC ) and AO4 ( ERC ) outputs.

Next GRM in chain collects the position in terms of a Volt signal at AI1 ( SRC ) and AI2 ( ERC ) input and compares it to the corresponding highest actual damper positions of its own.

The higher value of these two compared values is passed on to the next GRM. The last GRM in chain use then highest actual damper positions in the whole system to regulate the fan speed.

See wiring scheme, GRM in cascade.

Note that in case of cascade connection one needs to ac-tivate Analog inputs which collect the damper positions from the previous GRM in cascade.

This is done in:

GRM menu -> System -> GRM cascade activ -> SRC ( AI1 ) and ERC ( AI2 )

Alarms in LRM/SRM”Comm. Error SRC1-26”

If there is no communication to the activated SRC ( 60 sec delay ).

”Comm. Error ERC1-4”

If there is no communication to the activated ERC( 60 sec delay ).

”Damper error SRC 1-26”

If the damper connected to the activated SRC haven’t moved more than the set hysteresis ( in % ) within the set time. Note! Is only alerting if the fan is running ( DI1 is con-nected to C+ ).

Alarms in GRM”Comm. Error LRM1-5”

If there is no communication to the activated LRM ( 60 sec delay ).

”SRC Comm Error LRM1-5”

Summary alarm for all SRCs in the LRM ( no delay ).

”ERC Comm Error LRM1-5”

Summary alarm for all ERCs in the LRM ( no delay ).

”SRC DamperError LRM1-5”

Summary alarm for all the SRC dampers in the LRM ( no delay ).

Controlling a LRM through GRM via touch buttons

In larger systems with several LRMs and a GRM, there is possibility to control ( overtake ) different LRMs with the GRM which they are connected to.

This is practical for system maintenance as GRM can be used to set different parameters in LRMs ( connected to the actual GRM ) without need to physically stand next to a LRM. The GRM by use of Control function simply overtakes the chosen LRM.

To use the Control function:

1. In GRM main menu choose Local Regula Master

2. Select the LRM which is to be controlled

To turn back to GRM, use “←” push button several times, until GRM menu appears.

Regula Combi PascalRegula Combi

( ver. 1.3-1-10 )

Regula Combi is a room con-troller for integrated instal-lation in products or directly on the wall. Regula Combi has a builtin temperature sensor and can use input from presence sensor, CO2 sensor and an external tempera-ture sensor. The display has indications for heating/cool-ing state, actual temperature and set point temperature when pressing increase/decrease buttons, and icons for the operating modes.

Regula Combi has 7 predefined programs which can be selected in the Service parameter menu in the display. Two of them are specially designed for Pascal VAV sys-tem.

Functions

The two Pascal programs in Regula Combi are called:

Program 6 Pascal VAV supply ( SRC )

Program 7 Pascal VAV exhaust ( ERC ).

Program 6 Pascal VAV supply ( SRC )

The regulation of temperature takes place in sequences with heating and cooling by signals from the universal outputs UO1 ( heating ) and UO2 ( cooling ), and the vol-ume flow regulator ( MBBV or VRU-2 ) must be connect-ed to the cooling output.

For easy commissioning all air flow settings for ventila-tion in the room are set in Regula Combi ( and not in the volume flow regulator ). The cooling part of the tempera-ture sequence will then result in variable output signals, which depend on four different air flow settings:

Minimum air flow at presence/occupied ( AirflowMinOcc )

Maximum air flow at presence/occupied ( AirflowMaxOcc )

Standby air flow ( AirflowStandby ) when there is no pres-ence, and a size dependable air flow ( AirflowNominal ). Normally AirflowNominal should not be changed manu-ally.

All air flows are set in the Service parameter menu (in l/s).

The size and number of connected volume flow regula-tors is also set in the service parameter menu.

Note: If more than one volume flow regulator is control-led by the same Regula Combi, the size of the volume flow regulators must be the same. Every volume flow reg-ulator size has predefined default values for AirflowNomi-nal, AirflowMaxOcc, AirflowMinOcc and AirflowStandby. These values can of course be changed, but are reset to default values if the parameter for size is changed.

l indab | pascal


Regula Combi PascalAn external CO2 sensor with relay ( CO2RT-R ) can be connected at DI2 and C+. When the limit for CO2 level is exceeded, and the relay connects DI2 with C+ the UO2 ( cooling ) signal will increase successively ( by 0.5V, 5%, for every minute ) until the CO2 level is beneath the lower limit with hysteresis. When it reaches this level the UO2 will decrease successively ( by 0.5V, 5%, for every minute ) until the output UO2 is controlled by temperature again.

Damper position is registered in Regula Combi as a 2-10V (DC) signal through AI2, and via EXOline it is used in Regula Master for fan optimization.

Also the air flow set point from Regula Combi is collected in Regula Master ( via EXOline ) and is used for exhaust regulation.

In program 6 the modes Off, Unoccupied, Standby, Oc-cupied and Bypass are used. The preset operating mode can be set ( default Occupied ).

Off can be reached by pressing the occupancy button for more than 5 sec. This will close the volume flow regulator damper ( with 0 V ).

In mode Unoccupied Regula Combi will use the setpoints heating setpoint at Unoccupied ( default 15°C ) and cool-ing setpoint at Unoccupied (default 30°C). Any setpoint displacement is not active in Unoccupied mode.

So if the actual temperature is lower than cooling set-point at Unoccupied (default 30°C) AirflowMinOcc is transmitted from the cooling output.

By connecting a presence detector to Regula Combi at DI1 and C+, Standby will occur if there is no occupancy in the room. ( Requirement for standby function is that the preset operating mode must be set to Standby and DI to Normally open ). When Standby is active a signal corresponding to the airflow setting AirflowStandby will be transmitted from the cooling output, however if the room temperature exceeds basic cooling setpoint ( de-fault 22°C ) + setpoint displacement + Neutral zone at Standby (default 2°), the cooling output will vary between AirflowStandby and AirflowMaxOcc.

If no presence detector is connected or if the presence detector indicates occupancy, mode Occupied will oc-cur. In Occupied mode cooling output will vary between AirflowMinOcc and AirflowMaxOcc.

Bypass can be reached by pressing the occupancy but-ton, and a signal corresponding to AirflowMaxOcc will be transmitted from the cooling output UO2.

The mode ( state ) of a SRC can be changed from LRM and by EXOline / Modbus commands via GRM/SRM. However to access Bypass from Unoccupied/Off and vice versa, it is necessary to use Occupied as a tempo-rary mode.

Heating output UO1 is exercised every 23 hour for 120 s.

Cooling output UO2 is exercised every 23 hour ( adjust-able ) for 30 s, i.e opening ( 10 V ) for 15 s and closing ( 0 V ) for 15 s. The 15 s is adjustable.

A heating function for UO2 can be activated ( by chang-ing parameter 11 to value 5 instead of 4 ).

This will allow UO2 to follow the heating signal UO1 to a free chosen max level ( parameter 49 ) when there is heating demand, though UO2 will still be limited by Air-flowMinOcc and AirflowMaxOcc.

This should only be used when having heated air ( above room temperature ) in the duct e.g. by connecting UO1 to a duct heater. If the heating function on UO2 is activated, forced cooling ventilation by pressing the Occupancy button will not lead to 100% signal on UO2.

Program 7 Pascal VAV exhaust (ERC)

In program 7 there is no temperature regulation. The con-troller serves as a translater for the calculated exhaust flow signal that is send from Regula Master ( via EXOline ).

The calculated exhaust flow signal is converted and transmitted to the cooling output UO2 depending on the chosen volume flow regulator size ( and thus Air-flowNominal ).

Every volume flow regulator size has predefined default values for AirflowNominal. This value can be changed, but is reset to default value if the parameter for size is changed.

Number of dampers is also adjustable ( default 1 ). If more than 1 damper is set then the calculated exhaust airflow will be divided.

The exhaust damper position is registered as a 2-10V (DC) signal through AI2 and is via EXOline used in Regula Master for fan optimization.

Accessories PascalCO2 Sensor with relay CO2RT-R

Regula Combi with program 6 ( Pascal VAV supply ) is prepared to handle a relay signal that indi-cates that air quality in the room is poor.

To give that signal the CO2 sensor with relay CO2RT-R must be used.

CO2RT-R is a wallmounted sensor for measuring carbon dioxide ( CO2 ) concentration in in-door environments. Measuring range is 0...2000ppm and it has relay output.

Alternatively CO2RT-R-D ( with display ) or CO2DT-R ( for duct mounting ) can be used.

Start-up

After applying power to the sensor, it will take a few min-utes before it shows correct values.

Calibration

CO2RT-R is factory calibrated before delivery and do not need to be calibrated at installation.

CO2RT-R is calibrated automatically, which means that manual recalibration is not required during the lifetime of the sensor.

Regula Combi PascalRegula Combi is shown in the picture to the left. There are four buttons on the RC, ( the one in the bottom with no indication is not used ). In the top, there is a ”occupancy” button, and below it there are ”˄”( increase ) and ”˅” ( decrease ) buttons.

Configuration of Regula Combi is done in the ”service” menu.

To enter the service menu :

PUSH SIMULTANOUSLY ”˄” and ”˅” buttons and hold them down in for 5 seconds until a ”service” indication appears in the display.

To scroll through parameters:

PUSH ”˄” and ”˅” buttons.

To see the actual value of the parameter:

PUSH ”occupancy” button,

and to scroll through possible values of the actual pa-rameter:

PUSH ”˄” and ”˅” buttons.

PUSH the ”occupancy” button ONCE MORE to exit the parameter.

NB ! ( Be careful with this. ”Occupancy” button saves the value of the parameter which is latest shown in the display ). To achieve the original value, i.e. the value before change, press the “˄ “ and “˅ “ button at the same time.

Then PUSH ”˄” button TWICE which leads you to the parametermenu ( servicemenu ). The Display shows ”P00”.

Setup of SRC and ERC PascalControl of Supply Regula Combi ( SRC ) from Local/Single Regula Master ( LRM/SRM )

For optimal control of states ( modes ) of SRC cen-trally from LRM ( and with Exoline/Modbus commands via GRM/SRM ) the SRC has to be configured properly regarding the preset mode and the DI1 ( digital input for presence sensor ).

Default setup in Regula Combi is without a presence sensor connected. If there is a presence sensor ( NO ) connected there are some parameters to be set.

No presence sensor (default):

• Parameter ”P60” is set to value ”0”, Normally Open.

• Parameter ”P45” is set to value ”3”, Occupied.

• Parameter ”P13” is set to value ”0”, disconnect timer with occupancy/unoccupancy: 0 min.

Presence sensor:

• Set Parameter ”P60” to value ”0”, Normally Open.

• Set Parameter ”P45” to value ”2”, preset mode: Standby

• Set Parameter ”P13” to the desired delay time, Disconnect timer with occupancy / unoccupancy, e.g. 30 min.

• Set Parameter ”P14” to the desired switch on delay for occupancy, e.g. 1 min.

• On Regula master ( LRM / SRM ), under Supply Regula Combi -> SRCxx ( SRC number in list ) -> Set remote state to “ No remote control “

Setup of Exhaust Regula Combi

ERC, Exhaust Regula Combi, is configured by entering the parameter menu, as described in ”Display buttons on Regula Combi” segment.

The following parameters have to be set:

• Set Parameter ”P00”, to value ”7”, to select program 7 ( Pascal VAV Exhaust (ERC ) ).

• In parameter ”P138”, type in number of dampers controlled by the actual ERC.

The calculated exhaust airflow will be divided if more than 1 damper is set. Dampers must have same size.

• In parameter ”P139”, type in size of the damper in term of an indication number from table “default values for dampers” shown below.

Cables PascalTransformer sizing

The needed size of 24 V AC transformer(s) can be defined by adding up the dimensioning power consumption [VA] of all the components. The transformer power must exceed this. Use only safety isolating transformers. Cal-culation of the current demand I:

I = (P1+P2+…+Pn) / U [A]

where:

Pn is the dimensioned power consumption for each component [VA]

U is the voltage (24) [V]

If the current demand I exceeds 6 A ( which corresponds to approximately 150 VA for a 24 V AC transformer ), it is necessary to use more transformers to prevent overheat-ing of Regula Connect and avoid the need for very thick supply cables.

Supply cable sizingThe wire size of the supply cable can be determined by calculating the resistance pr meter R. The calculation presupposes that a voltage drop of e.g. 2 V is accepted in the supply cable:

R(per m) = Udrop / (I * L) [Ω/m]

where:

Udrop is the accepted voltage drop (2 V) in the cable [V]

I is the current [A]

L is the longest distance of supply cables from transformer to a component [m]

Example:

Udrop = 2 V, I = 4 A, L = 20 m

R (per m) = 2V / (4A * 20m) = 0,025 Ω/m

Regula Combi

Problem:There is no light or digits shown in Regula Combi.

Solution:

• Check supply cables.

( There must be 24 V AC – L on 10 and N on 11 ).

If Regula Combi is supplied from Regula Connect Pascal with RJ45 patch cable, then the female connector “Rc in/out” must be used.

The wiring in Regula Combi should be:

White/brown to 10 and Brown to 11.

There is no power supply in the “Rc Link” connectors.

Problem:Damper position is not shown in Local/Single Regula Master.

Solution:

• Check that program 6 for SRC function or program 7 for ERC function is selected in parameter P00.

• Check the cables from the actuator.

Actuator to Regula Connect Pascal: Black ( 1 ) to “Damper out – N”, Red ( 2 ) to “Damper out – L”, White ( 3 ) to “Damper out – S”, Orange ( 5 ) to “Damper in – Pos”.

Regula Connect Pascal to Regula Combi: White/brown to 10, Brown to 11, Green to 24 and White/orange to 31.

Actuator directly to Regula Combi: Black ( 1 ) to 21, Red ( 2 ) to 20, White ( 3 ) to 24 and Orange ( 5 ) to 31.

Problem:Damper is fully closed.

Solution:

• Check if Regula Combi is set to mode off ( there is no light in Regula Combi and “OFF” is displayed in left bottom corner ).

• Check the cables from the actuator ( see issue above ).

• If Regula Combi is wired with patch cable directly at terminals:

Check the type of termination of the RJ45 plug that is connected to Regula Connect Pascal.

If terminated with the T568A standard:

Pin 1 White/green, 2 Green, 3 White/orange, 4 Blue, 5 White/blue, 6 Orange, 7 White/brown, 8 Brown.

If the cable termination is of the type T568B, then switch the following wires in Regula Combi:

White/Green with White/Orange and Green with Orange.

See notes for Wiring diagram: Regula Connect wiring.

Problem:Display shows strange numbers e.g parameter 222.

Solution:

• Regula combi has probably been short circuited, check the cables to Regula Combi. If it still doesn´t work change to a new Regula Combi.

Problem:Regula Combi is in stand-by mode at all times.

Solution:

• Is there a presence sensor connected?

If so parameter P45 = 2 and P60 = 0. ( For a normally open ( NO ) sensor ).

No presence sensor P45 = 3

Sensors and actuators

Problem:The presence sensor in the diffuser is not working.

Solution:

• Check that the RJ plugs are pushed fully into the female connector.

• Does the diode on Regula Convert light?

If not check the wiring to Regula Connect Pascal:

Pin 2 ( Black ) to “Presence out – L”, Pin 3 ( Red ) to “Presence out – N”, Pin 4 ( Green ) to “Presence out – S2” and Pin 5 ( Yellow ) to “Presence out – S1”.

• Check that parameter P60 is set to value “0”, ( Normally Open ) and parameter P45 is set to value “2”, ( Preset mode: Standby )

• Set parameter P13 to the desired disconnect time, e.g. 30 min.

Problem:The CO2 sensor is not working.

Solution:

• A CO2 sensor with relay and settings for switch-on level and hysteresis must be used ( CO2RT-R ).

Hysteresis ( switch-off level ) must be set lower than switch-on level.

• Check the wiring in CO2RT-R.

The Normally Open terminal must be used, i.e. 3 ( Common ) and 4 ( Normally open ).

• When the relay is on, the UO2 on Regula Combi will slowly increase ( 0,5 V per minute ), however UO2 will always be limited by AirflowMinOcc and AirflowMax- Occ ( with default Airflow values it is 3,1 V to 6,5 V ).

Problem:The heating actuators does not regulate the valves.

Solution:

• Make sure that parameter P20 is correctly set – the default for program 6 is value “3” ( Heating actuator 0-10 V ). Use only 0 - 10 V actuators in Pascal.

NOTE ! It is not allowed to connect 24 V on/off thermal actuators through Regula Connect Pascal.

Problem:MBBV/VRU-MF is 100% open and/or have negative pressure when checking with ZTH-GEN.

Solution:

• Are the hoses to Belimo actuator switched?

Check that +( plus ) and -( minus ) hoses are correct mounted to the actuator

• See if the hoses to the actuators are bent or squeezed, they mustn´t be.

• Are MBBV / VRU-MF getting the airflow that they need?

Connect ZTH to the actuator to see the actual flow, if flow is lower than the damper needs, this explains the 100% open damper.

• Check if the wiring is correct between Pascal connect card and the MBBV/VRU-MF. ( Or between Regula combi and MBBV/ VRU-MF ).

Regula combi to MBBV/VRU-MF. 21 to 1 black 20 to 2 red 24 to 3 white 31 to 5 orange

Pascal connect card and MBBV/VRU-MF. Check that the cable is “clicked” in correctly.

Problem:Actual air flow for a SRC / ERC does not correspond to the actual air flow read in ZTH-GEN for MBBV / VRU-MF

Solution:

• Check that the correct size is chosen in Regula Combi ( P139 ), and check that the nominal flow ( P143 ) corresponds to the Vnom for MBBV / VRU-MF read in ZTH-GEN.

There can be a deviation of 1 to 2 l/s.


78

l indab | pascal


Communication

Problem:There is no communication between a specificRegula Combi and the Local/Single Regula Master( RC parameters are not readable in RM ).

Solution:

• Check if the Regula Combi PLA:ELA address is correctly typed in Regula Master.

• Check that the same wire colors for A and B are used in both Regula Combi (A in 42, B in 43) and Regula Master ( A in 55 - Port 2, B in 54 – Port 2 ).

• Check that the cable shield is connected to 56 N - Port 2 in Regula Master.

( Shield is not connected in Regula Combi ).

The above items is checked and there is communica-tion to some Regula Combi in Regula Master.

• Find out where the last Regula Combi with function- ing communication is placed – “last” means farthest away on the communication cable.

Follow the communication cable to the next Regula Combi.

Check that the supply cables on this Regula Combi are correctly connected to the terminals - L on 10 and N on 11.

If they are switched the communication will fail !

The address and all cables are checked and there is still no communication to a specific Regula Combi.

• Place one of the other Regula Combi’s, which there IS communication to, in the terminal bottom part.

If there is communication with the Regula Combi, then Lindab should be contacted for a possible change of the Regula Combi.

Problem:GRM /SRM is not responding Modbus queries from BMS.

Solution:

• As default Modbus communication is not activated.

Activation is done in:

GRM / SRM menu -> System -> Communication -> Modbus slave communication ( Yes / No ) -> Modbus address ( 1 ).

Regula Master

Problem:The Operating Control function for damper behavior is not working, and the fans doesn´t get any 0-10V signal.

Solution:

• Check the connection between 71 DI1 and 4 +C.

The connection must be closed to get damper alarms.

If the connection is open the Pascal system will inter- preter that the fan has stopped, and therefore all dampers is supposed to stay fully open.

So if a digital signal ( whether the fan is running or not ) is unavailable from the AHU controller, there must be a short-circuit between 71 DI1 and 4 C+.
