MountingObserve the following guidelines when mounting aVMA:

Note: When the air supply to the VAV boxis below 10°C (50°F), make sure that anycondensation on the VAV box, particularly onthe damper shaft, does not enter the VMA

• Ensure that the mounting surface can supportthe controller and any user-supplied enclosure.electronics. Mount the controller vertically abovethe damper shaft to allow any shaft condensationto fall away from the controller. Additionalmeasures may be required in some installations.

• Mount the controller on a hard, even surfacewhenever possible.

• Use shims or washers to mount the controllersecurely and evenly on the mounting surface.

• Mount the controller in an area free of corrosivevapors that matches the ambient conditionsspecified in the Technical specifications section.

• Provide sufficient space around the controllerfor cable and wire connections and adequateventilation through the controller (at least 50 mm[2 in.] on the top, bottom, sides, and front of thecontrollers).

• Mount the VMA vertically above the damper shaftto allow any shaft condensation to fall away fromthe VMA.

Do not mount the controller in areas whereelectromagnetic emissions from otherdevices or wiring can interfere with controllercommunication.

• Avoid mounting the controller on surfaces withexcessive vibration.

On panel or enclosure mount applications, observethese additional guidelines:• Do not install the controller in an airtight

enclosure.

• Mount the controller so that the enclosure wallsdo not obstruct cover removal or ventilationthrough the controller.

• Mount the controller so that the powertransformer and other devices do not radiateexcessive heat to the controller.

To mount the controllers, complete the followingsteps:1. Set all the switches on the field controller to

their known settings.

2. Place the controller in the proper mountingposition on the damper shaft so that the wiringconnections are easily accessible. Make surethe controller base is parallel to the VAV box(perpendicular to the damper shaft). If needed,use a spacer to offset tipping of the controllercaused by the shaft bushings.

Note: Use the alignment marks to centerthe captive spacer to ensure sufficientmovement in either direction.

3. Secure the self-drilling No. 10 screw throughthe captive spacer with a power screwdriverand 100 mm (4 in.) extension socket. Otherwise,use a punch to mark the position of theshoulder washer, and then drill a hole into theVAV box using a 3.5 mm (9/64 in.) drill bit. Insertthe mounting screw and tighten against thespacer.

Important: Do not overtighten the screw,or the threads may strip. If mounting tothe VAV box, make sure the screws do notinterfere with damper blade movement.

4. Locate the damper position using the typicalmarking on the end of the damper shaft asshown in the following figure.

Figure 2: Typical Damper End Shaft Icons

5. Note the direction, clockwise (CW) orcounterclockwise (CCW), required to close thedamper. Grasp the damper shaft firmly withpliers, and either manually close the damper for90° boxes or manually open the damper for 45°or 60° boxes.

6. Push down and hold the Manual Overridebutton (see VMA1930 physical features) andturn the controller coupler until it contacts themechanical end-stop at either the full-closed(90° boxes) or full-open (45° and 60° boxes)position.

7. If the damper for a 90° box closes CCW, rotatethe coupler to the CCW mechanical limit. Ifthe damper for a 90° box closes CW, rotatethe coupler to the CW mechanical limit. Theopen end-stop is automatically set for 90°boxes. For 45° and 60° boxes, hard stops mustbe provided at both full-closed and full-opendamper positions. By installing the controller atthe full-open position, the controller providesthe open stop for 45° and 60° boxes. The closeddamper seal provides the full-closed stop.

Note: The integrated actuator has astroke time of 60 seconds for 90° of travel.The stroke time is the amount of time(in seconds) that it takes the actuatorto move from the fully closed to fullyopened position or from fully open to fullyclosed position. For proper operation, theactuator stroke time must be configuredin the CCT application based on the actualtime it takes the actuator to drive thedamper. The default setting is 60 seconds(for 90° VAV boxes). For 45° and 60° VAVboxes, the actuator stroke time must beadjusted. Refer to Controller Tool Help(LIT-12011147) for instructions on settingthe actuator stroke time in the application.

8. All models are compact in size and can beeasily installed on VAV boxes. The models haveeither a round shaft up to 13 mm in diameteror a 10 mm square shaft. Tighten the squarecoupler bolt to the shaft using an 8 mm (5/16in.) wrench or 10 mm (3/8 in.) 12-point socket.Tighten to 10.5 to 11.5 N·m (95 to 105 lb·in).

9. (Skip this step if you are installing theVMA1626 model) Loop the pneumatic tubing(supplied by field personnel) to include atrap for condensation. Attach the neededlength of tubing (supplied and installed byfield personnel) to the dual port fitting on thecontroller and the other ends of the tubingto the pressure transducer in the VAV boxapplication.

Note: The controller uses a digital non-flow pressure sensor with bidirectionalflow operation. You can connect the high-and low-pressure DP tubes to eitherbarbed fitting on the controller. You do notneed to make a specific high- or low-sideconnection when you attach the tubing tothe barbed fittings on the controller.

10. Push the Manual Override button, and turn theactuator coupling manually to ensure that theactuator can rotate from full-closed to full-openpositions without binding.

11. Complete the mounting by rotating the damperto the full-open position.

 CAUTION

Risk of Property DamageRotate the damper to the full-open position beforestarting the air handler. Failure to rotate the damper tothe full-open position may result in damage to the VAVbox or ductwork when the air handler is started.

 ATTENTION

Risque de décharge électriqueDébrancher l'alimentation avant de réaliser tout rac-cordement électrique afin d'éviter tout risque dedécharge électrique.

Important: Do not connect supply powerto the controller before finishing wiring andchecking all wiring connections. Short circuitsor improperly connected wires can resultin damage to the controller and void anywarranty.

Important: Do not exceed the controllerelectrical ratings. Exceeding controller electricalratings can result in permanent damage to thecontroller and void any warranty.

Important: Use copper conductors only. Makeall wiring in accordance with local, national, andregional regulations.

Important: Electrostatic discharge candamage controller components. Use properelectrostatic discharge precautions duringinstallation, setup, and servicing to avoiddamaging the controller.

For information on configuring and wiringa BACnet/IP network, refer to the Metasys IPNetworks for BACnet/IP Controllers ConfigurationGuide (LIT-12012458). For detailed information onconfiguring and wiring a SA Bus, refer to the MS/TPCommunications Bus Technical Bulletin (LIT-12011034).

Network topologyVMA1930 controllers may be connected to a buildingautomation network in multiple ways: as daisy-chained devices, as part of a star (also called homerun) type network, or as part of a ring network.To daisy-chain VMA1930 controllers, connect thecontrollers to the bus supervisor in a chain withthe Ethernet cable connecting to the VMA1930at the ETH1 or ETH2 port, and connecting to thenext device from the other port. Benefits of daisy-chained networks are that they require less physicalwiring and new devices can be added easily to thenetwork.In a star network, each VMA1930 controller isconnected by Ethernet cable directly back to a main

switch. This configuration reduces the possibility ofnetwork failure but requires more wiring to install.A ring network is a chain of controllers virtuallyclosed by a software component in an Ethernetswitch. Not all switches support the ring topology.The dual-port controller from Johnson Controlssupports Media Redundancy Protocol (MRP). WithMRP, a chain of Ethernet devices can overcome anysingle communication failure, with a recovery timefaster than in a BACnet system.For more information about network topologies forMetasys BACnet/IP Controllers, refer to the MetasysIP Networks for BACnet/IP Controllers ConfigurationTechnical Bulletin (LIT-12012458).

VMA terminals and bus portsSee VMA1930 physical features for input and outputterminal and bus port locations on the controllers.Observe the following guidelines when wiring aVMA controller.

Input and Output terminalsThe input spade terminals are located on thebottom of the VMA near the FC Bus terminal block.The output spade terminals are located on the topof the controller near the power supply terminalblock. For more information, see Table 3.

SA Bus terminal blockThe SA Bus terminal block is a brown, removable,4-terminal plug with +15 VDC that fits into a board-mounted jack. Wire the removable SA Bus terminalblock plugs on the VMA and other SA Bus devicesin a daisy-chain configuration using 4-wire twisted,shielded cable as shown in Figure 3. See Table 5 formore information.

Figure 3: SA bus terminal block wiring

SA Bus portThe Sensor (SA Bus) port on the bottom of thecontroller is an RJ-12, 6-position modular jack thatprovides a connection for the Mobile Access Portal(MAP) Gateway, the Bluetooth CommissioningConverter (BTCVT), the VAV Balancing Tool, specifiednetwork sensors, or other SA Bus devices with RJ-12plugs. A DIS1710 Local Controller Display can also beconnected to the SA Bus port.

Note:• Do not use the modular SA Bus port and the

terminal block SA Bus simultaneously. Onlyuse one of these connections at a time.

• The MAP Gateway serves as a replacementfor the BTCVT, which is no longer availablefor purchase, but continues to be supported.

The Sensor port is connected internally to the SAbus terminal block. For more information aboutSensor port functions, requirements, and ratings,see Table 5.

Figure 4: Pin number assignments for Sensor(SA Bus) Port on VMA1930

Supply power terminal blockThe 24 VAC supply power terminal block is agray, removable, 2-terminal plug that fits into aboard-mounted jack on the upper left of the VMAcontroller.Wire the 24 VAC supply power wires from thetransformer to the HOT and COM terminals on theterminal plug as shown in the following figure. SeeTable 5 for more information.

Figure 5: 24 VAC supply power terminal blockwiring

The supply power wire colors may be different ontransformers from other manufacturers. Refer tothe transformer manufacturer’s instructions andthe project installation drawings for wiring details.

Important: Connect 24 VAC supply power tothe controller and all other network devicesso that transformer phasing is uniform acrossthe network devices. Powering networkdevices with uniform 24 VAC supply powerphasing reduces noise, interference, andground loop problems. The controller does notrequire an earth ground connection. However,when grounding the secondary of the 24 VACtransformer is required, only one connection toground should be made near the transformer.See the following figure.

Setup and adjustmentsImportant: Electrostatic discharge candamage controller components. Use properelectrostatic discharge precautions duringinstallation, setup, and servicing to avoiddamaging the controller.

Setting the controller numberEach controller on a network must have a uniquenumber on the subnet where it resides in order

to identify it in the Controller Tool for uploading,downloading, and commissioning.The controller number is set using three rotaryswitches and may be numbered from 000 to 999.The numbers are ordered from left to right, mostsignificant bit (MSB) to least significant bit (LSB).In the following figure the switches are set to4 2 5, designating this controller as controllernumber 425. The controller number must matchthe controller number defined in ControllerConfiguration Tool (CCT) under Define Hardware

> Network Settings. The number of the controllercan be written in the white squares provided so thecontroller number can be more easily seen from adistance.

Figure 8: Rotary switch for setting controllernumbers

Note: The BACnet device ID is calculatedusing the value of controller number added to2000000. A device ID configured in this mannerdoes not require any configuration from CCT.

Input/Output Wiring ValidationThe VMA1930 controllers ship with a default statethat can assist in validating the wiring of the inputand output terminals prior to download of anapplication file. When the controller is powered onin this state, the Fault LED will flash in a pattern oftwo quick blinks and then a long pause (see Table7).To make use of this feature, ensure the rotaryswitches are set to the desired controller numberand wire the input and output terminals. Applypower to the VMA1930 controller and connect to thedevice with either a MAP Gateway or MS-DIS1710-0Local Display to view the points in the controller.The VMA1930 controller will report an Operationalstatus even though there is no true applicationloaded. CCT will not be able to commission orupload the device as a result until a true applicationis downloaded. The application name displayed willbe the controller number followed by the model ofthe controller and “Default State”.

For example, a VMA1930 controller whose rotaryswitches are set to 8 would have the default stateapplication name of 8-VMA1930 Default State.The default state creates I/O points for allconnections on the input and output terminals,including the integrated DPT. It assumes allUniversal Inputs (UIs) are Nickel temperaturesensors. All Configurable Outputs (COs) are treatedas Binary Outputs (BOs) with an initial value of0. The actuator on the VMA1930 will drive to the50% setting. The default state also takes inputfrom a Network Sensor at address 199. If there isno connected Network Sensor, the startup of thisdefault state will be delayed by 30 seconds as thecontroller attempts to establish connection with thesensor.

Commissioning Field ControllersTo commission the VMA1930 controller, use thefollowing procedure:1. Download the control application to the

controller using the Controller ConfigurationTool (CCT). Refer to the Controller Tool Help(LIT-12011147) and Controller Provisioning withTools (LIT-12013247) .

2. Commission the VAV Box.

3. Perform airflow balancing on the VAV box.Refer to the VAV Balancing Tool Technical Bulletin(LIT-12011087).

4. Perform commissioning checkout procedures.Refer to the Controller Tool Help (LIT-12011147) and Controller Provisioning with Tools(LIT-12013247).

You commission controllers with the CCT software.The controller can be connected in one of fourways; either through NxE Passthru, MAP 4.2+/BACnet Router (Mobile Access Portal (MAP)Gateway at version 4.2 or above), through Bluetooth(using BTCVT), or Direct Ethernet connection tothe controller. Refer to the Controller Tool Help(LIT-12011147) and Controller Provisioning withTools (LIT-12013247) for detailed information aboutcommissioning field controllers.

Note:• The Bluetooth connection can be used

to Transfer to Computer (Upload) andcommission the controller, but cannot beused to Transfer to Device (Download).

• The MAP Gateway serves as a replacementfor the BTCVT, which is no longer availablefor purchase, but continues to be supported.

Firmware Package FileThe MS-FCP-0 equipment controller firmwarepackage files are required for CCT to configure andcommission the controllers. The firmware packagefiles also allow you to upgrade an existing controller

to the latest firmware release available for thatcontroller.Beginning at CCT Release 13, the firmware packagefiles are orderable separately; they are not includedwith CCT. They are obtained from the Metasys software licensing portal, and are loaded andlicensed on the computer/server that is runningCCT.For additional information about the firmwarepackage files, refer to the CCT Installation Instructions(LIT-12011259).

Troubleshooting Field ControllersObserve the Status LEDs on the front of theexpansion module. Table 7 provides LED statusindicator information for troubleshooting theexpansion module.General troubleshooting provides some additionaltroubleshooting information for possible problems.

Note: If you experience short circuits in the 24VAC power supply causing protective devicessuch as breakers or fuses to trip, make surethat the power connections on theVMA1930 arenot reversed. The most common cause of this

problem is when the 24 VAC power supply onthe VMA1930 is reversed but not reversed on aconnected secondary device. Improper wiringof this power terminal may cause a short circuitacross the 24 VAC power supply.

LED status and statesTable 7: Status LEDs and description of LED statesLED label LED color Normal state Descriptions of LED states

General troubleshootingTable 8: TroubleshootingProblem Possible cause and correction Verification

Controller is OFF.Transformer has tripped:Power is at Primary of Transformer, 0V atSecondary.

Breaker/Fuse has tripped:Power is at Primary of Transformer, 24V atSecondary, 0V at Fuse/Breaker.

Cause:1. Transformer is shorted.2. 24 VAC powered sensor is not

wired with the same polarity as thecontroller.

3. SA Bus device is not wired with thesame polarity as the controller.

Correction:1. Ensure polarity of ~24 V COM / ICOM /

+ 15VCOM/SA BUS COM on thecontroller, auxiliary devices, and I/O isthe same.

2. Ensure OUT1-OUT3 terminals of binaryoutputs are not connected to ~24VAC COM, and verify that OCOM1-OCOM3 are not connected to ~24 VACHOT (these terminals are internallysourced).

3. Verify the short circuit has beenresolved with an ohm-meter.

4. Reset the breaker/fuse or replace thetransformer.Note: When replacing thetransformer, it is recommended toreplace with a model that utilizes aresettable circuit breaker. A circuitbreaker makes solving wiringproblems easier.

1. Disconnect the Secondary of the 24VAC transformer.

2. Use an ohm-meter to measurebetween ~24 V HOT and COM; theremust be no short circuit.Note: Some installations requirethe Secondary of the Transformerto be Earth Grounded. If this isthe case, verify that the EarthGround connection is valid and notshared between multiple pieces ofequipment.

Configurable output - analog mode isinvalid:0–10 V output is set to 10–100%, but 0 V is atoutput terminals.Output is in protection mode, a state theanalog portion of the configurable outputgoes into when it detects a wiring problem.The analog output is set to 0% regardlessof the command whenever a wiring fault isdetected.

Cause:There is a power polarity mismatch betweenthe connected device and the configurableoutput.Correction:Ensure polarities of ~24 V COM/OCOMmatch and that the connected end deviceuses the same polarity.

1. Measure the output and verify that itmatches the command.

2. Disconnect the connected deviceand verify the commanded value ispresent.

Configurable output - analog mode isinvalid:0–10V output has an undesirable offset of upto 1 V.The Common Reference is incorrect.

Cause:The OCOM terminal is not connected.Correction:Connect the OCOM terminal of theconfigurable output to the common of theconnected end device.

1. Measure the output and verify that itmatches the command.

2. Disconnect the connected deviceand verify the commanded value ispresent.
