M4-CGM General Purpose ApplicationControllers Installation Guide

ApplicationThe CGM09090 General Purpose Application MS/TP Controller (CGM) are equipment controllersthat run pre-engineered and user-programmableapplications, and provides the inputs and outputsrequired to monitor and control a wide variety ofHVAC and other facility equipment. CGM controllersoperate on an RS-485 BACnet® MS/TP Bus asBACnet Advanced Application Controllers (B-AACs)and integrate into Johnson Controls® and third-party BACnet systems.CGM equipment controllers include an integral real-time clock, which enables the controllers to monitorand control schedules, calendars, and trends, andoperate for extended periods of time as stand-alonecontrollers when offline from the Metasys® systemnetwork.

Communications ProtocolsThe CGM controllers can communicate using BACnetMS/TP, N2, or wireless Zigbee®. By default, theCGM controllers communicate using the BACnetMS/TP protocol. The BACnet protocol is a standardfor ANSI, ASHRAE, and the International StandardsOrganization (ISO) for building controls.The CGM controllers can be used as functionalreplacements for legacy N2 controllers. The N2-capable MS/TP equipment controller modelsprovide a cost-effective upgrade and modernizationpath for customers with existing N2 controllers.For installation and commissioning support,and tips for efficient and safe replacement,refer to the Modernization Guide for Legacy N2Controllers (LIT-12012005) and the controller-specific documentation. For information aboutmapping N2 Objects in controllers with switchablecommunications protocols, refer to the N2Compatibility Options chapter of the Controller ToolHelp (LIT-12011147).To configure CGM controllers to communicate usingthe N2 communications protocol, see ConfiguringN2 communications.The CGM controller can also be installed in awireless application using aZFR/ZFR Pro WirelessField Bus Router. To configure these controllers tocommunicate using the wireless communicationsprotocol, see Configuring wireless communications.

Terminal blocks and bus portsSee CGM09090 physical features for terminal blockand bus port locations on the CGM controller.Observe the following guidelines when wiring a CGMcontroller.

Input and Output terminal blocksOn the CGM controller models, the input andoutput terminal blocks are removable. All of theinput terminal blocks are mounted on the bottomof the controller, and the output terminal blocksare mounted on the top of the controller. Forinformation about removing a terminal block, seeRemoving a terminal block. For more informationabout I/O terminal functions, requirements, andratings, see Terminal wiring guidelines, functions,ratings, and requirements.


FC bus terminal block (or N2 protocol asrequired)The FC bus terminal block is a blue, removable, 4-terminal plug that fits into a board-mounted pinheader.Use a 3-wire twisted, shielded cable, as shown inFigure 4, to wire the removable FC bus terminalblock plugs on the controller, and other controllers,in a daisy-chain configuration. For more informationabout FC Bus terminal functions, requirements, andratings, see Table 7.

Note: The POWER terminal supplies 15 VDC.The POWER terminal can be used to connect(daisy chain) the 15 VDC power leads on the SAbus.

Note: Do not use the modular SA Bus port andthe terminal block SA Bus simultaneously. Onlyuse one of these connections at a time.

Note: The CGM controller is the EOL for the SABus.

FC bus portThe FC bus port on the front of the controller isan RJ-12, 6-position modular jack that providesa connection for the Mobile Access Portal (MAP)Gateway, or the ZFR/ZFR Pro Wireless Field BusRouter.The FC bus port is connected internally to the FC busterminal block. See Table 7 for more information.The FC bus port pin assignment is shown in Figure 6.


Note: The MAP Gateway serves as areplacement for the BTCVT, which is no longeravailable for purchase, but continues to besupported.

Figure 6: Pin number assignments for FC bus andSA bus ports on equipment controllers

SA Bus portThe Sensor (SA Bus) port on the front of thecontroller is an RJ-12, 6-position modular jack thatprovides a connection for the MAP Gateway, BTCVT,the VAV Balancing Tool, the DIS1710 local controllerdisplay, specified network sensors, or other SABus devices with RJ-12 plugs. When the CGM isconfigured for N2 network communication, youmust download and commission the controller usingthe SA Bus port.

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

Configuring N2 communicationsN2-capable controllers support the full range ofpossible N2 device addresses provided by the N2protocol standard (1-254).To configure a controller to communicate using theN2 protocol, complete the following steps:

1. Disconnect the 24 VAC supply from thecontroller.

2. Set the address switches to the desired N2address. For details about setting a deviceaddress, see Setting the device address.

3. Reconnect the 24 VAC supply to the controller.

4. Using an SA bus connection, download thefirmware and controller application fileconfigured for N2 to the controller.

Switching the CommunicationsProtocol from N2 to MS/TPFor N2 sites that are converting to BACnet MS/TP,you can switch the communications protocol of N2-configured MS/TP controllers back to BACnet MS/TP.To switch the CGM controller operating in N2mode back into BACnet MS/TP mode, complete thefollowing steps:


2. Set the address switches to the desired BACnetMS/TP address. For details about setting adevice address, see Setting the device address.


4. Using an SA Bus connection, download acontroller application file configured for BACnetMS/TP to the controller.

Configuring wirelesscommunicationsTo configure a controller for use with the ZFR/ZFRPro Series Wireless Field Bus system, complete thefollowing steps:


2. Wire the input/output terminals and SA bus.

Note: In wireless network applications,do not connect any wires to the FC busterminal block. (Connect the FC/SAterminal block on an IOM to an SA busonly.)

3. Important: Before the CGM controller ispowered on, connect the ZFR/ZFR Pro WirelessField Bus Router to the FC bus port (RJ-12modular jack) on the front of the controller.


4. Ensure that the controller's rotary switches areset to the correct device address. For detailsabout setting a device address, see Setting thedevice address.


For more information about the ZFR ProWireless Field Bus system, refer to theWNC1800/ZFR182x Pro Series Wireless FieldBus System Product Bulletin (LIT-12012320).For more information about the ZFR 1800Wireless Field Bus system, refer to theZFR1800 Series Wireless Field Bus SystemProduct Bulletin (LIT-12011336).

Setting the device addressMetasys equipment controllers are master deviceson MS/TP (FC or SA) buses. Before you operatecontrollers on a bus, you must set a valid andunique device address for each controller on thebus. You set the CGM device address by setting thepositions of the Device Address rotary switches atthe top of the controller.The following table describes the valid rotaryswitch device addresses for communications busapplications.Table 9: Switch device addressesFC Bus CommunicationMode Valid Device Address Range

Wired MS/TPcommunication

4-127Note: Addresses 0-3 arereserved and not for use onequipment controllers.

Zigbee wirelesscommunication

4-127Note: Addresses 0-3 arereserved and not for use onequipment controllers.

N2 communication

1-254Note: Addresses 0 and 255 arereserved and not for use onequipment controllers.

Note: The controller auto-detects if thecommunication protocol is wired MS/TP, ZigbeeWireless, or N2 on the FC Bus.

The device address is a decimal address that isset using three rotary switches. The numbersare ordered from left to right, most significantbit (MSB) to least significant bit (LSB) when thecontroller is oriented as shown in CGM09090physical features. In the following figure, the

switches are set to 1 2 3, designating thiscontroller's device address as 123.

Figure 9: Device address rotary switch block

The device address must match the deviceaddress defined in the Controller ConfigurationTool (CCT) under Define Hardware > NetworkSettings.

To set the device addresses on CGM controllers,complete the following steps:

1. Set a unique and sequential device address foreach of the equipment controllers connectedon the FC or SA Bus, starting with deviceaddress 4.

2. To ensure the best bus performance, setsequential device addresses with no gaps inthe device address range (4, 5, 6, 7, 8, 9, andso on). The equipment controllers do not needto be physically connected on the bus in theirnumerical device address order.

3. Write each controller's device address on thewhite label below the device address rotaryswitch block on the controller's cover.

Refer to the MS/TP Communications BusTechnical Bulletin (LIT-12011034) for moreinformation about controller deviceaddresses and how to set them on MS/TPbuses.

Removing a terminal blockTo remove the terminal block from the circuit board,complete the following steps:

Note: You need a flat blade screwdriver toremove the terminal block.


1. To prevent any possibility of damage from anaccidental short, remove power from thecontroller.

2. Underneath the terminal block, in the small gapbetween the bottom of the terminal block andthe circuit board, insert the flat blade of thescrewdriver.

Figure 10: Terminal block

3. To detach the left-hand side of the terminalblock, position the flat blade underneath theterminal block to the left, and push down thescrewdriver handle. When you do this, you areusing the screwdriver as a lever to pry up theterminal block.

4. To detach the right-hand side of the terminalblock, position the flat blade underneath theterminal block to the right, and push down thescrewdriver handle.

5. If necessary, repeat steps 3 and 4 until theterminal block is removed.

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

Important: Disconnect all power sourcesto the controller before removing cover andchanging the position of any jumper or the EOLswitch on the controller. Failure to disconnectpower before changing a jumper or EOL switchposition can result in damage to the controllerand void any warranties.

The controller cover is held in place by fourplastic latches that extend from the base andsnap into slots on the inside of the housingcover.

To remove the controller cover, complete thefollowing steps:

1. Place your fingertips under the two cover lifttabs (CGM09090 physical features) on the sidesof the housing cover and gently pry the top ofthe cover away from the base to release thecover from the two upper latches.

2. Pivot the top of the cover further to release itfrom the lower two latches.

3. Replace the cover by placing it squarely overthe base, and then gently and evenly push thecover on to the latches until they snap into thelatched position.

Cover removed, EOL switch, and currentjumpers

Figure 11: CGM with cover removed showing EOLswitch and jumper positions

Setting the End-of-Line (EOL) switchEach CGM controller has an EOL switch, which, whenset to ON (up), sets the controller as a terminatingdevice on the bus. See Figure 11 for the EOL switchlocation. The default EOL switch position is OFF(down).

Figure 12: End-of-Line switch positions

To set the EOL switch on a controller, complete thefollowing steps:


1. Determine the physical location of thecontroller on the FC bus.

2. Determine if the controller must be set as aterminating device on the bus.

Note: For detailed information aboutEOL termination rules and EOL switchsettings on FC buses, refer to the MS/TP Communications Bus Technical Bulletin(LIT-12011034).

3. If the controller is a terminating device onthe FC bus, set the EOL switch to ON. If thecontroller is not a terminating device on thebus, set the EOL switch to Off.

When a controller is connected to powerwith its EOL switch set to ON, the amberEOL LED on the controller cover is illumi-nated.

Setting the input jumpers

CAUTION

Risk of Electric Shock:Disconnect supply power to the field controller beforeattempting to adjust the Binary Output Source PowerSelection Jumpers. Failure to disconnect the supplypower may result in electric shock.

ATTENTION

Mise En Garde: Risque de décharge électrique:Débrancher l'alimentation de l'controller avant toutréglage du Binary Output Source Power SelectionJumpers. Le non-respect de cette précaution risquede provoquer une décharge électrique.

UI current loop jumpersThe UI current loop fail-safe jumpers are on thecircuit board under the controller cover near the UIterminals (Figure 11). When a UI is defined (in thesystem software) as a 4-20 mA Analog Input and theUI’s current loop jumper is in the Disabled (default)position (Figure 13), the internal 100 ohm loadresister is disconnected and the 4-20mA currentloop is open.

Figure 13: Exchange enable and default settings

Setting the current loop jumper to the Enabledposition, (Figure 13) connects an internal 100 ohmresistor across the UI terminals, which maintains the4-20 mA current loop circuit even when power to thecontroller is interrupted or off.

Important: Current Loop jumpers must be inthe Disabled (default) position for all UIs thatare not set up to operate as 4-20 mA analoginputs.

The following table identifies the current loopswitches associated with each UI on the CGMcontroller.Table 10: CGM UI Inputs and jumper labelsUniversal Inputlabel Jumper label on circuit board

Setting up a local displayCGM models do not have an integral display, butcan be connected to a DIS1710 Local ControllerDisplay. For detailed information about settingup and operating a remotely connected DIS1710display, refer to the DIS1710 Local Controller DisplayTechnical Bulletin (LIT-12011270) .

Input/Output Wiring ValidationThe CGM controllers ship with a default state thatcan assist in validating the wiring of the input andoutput terminals prior to download of an applicationfile. When the controller is powered on in this state,the Fault LED will flash in a pattern of two quickblinks and then a long pause (see Table 11).To make use of this feature, ensure the rotaryswitches are set to the desired address and wire theinput and output terminals. Apply power to the CGM


controller and connect to the device with either aMAP Gateway or MS-DIS1710-0 Local Display to viewthe points in the controller. The CGM controller willreport an Operational status even though there isno true application loaded. CCT will not be able tocommission or upload the device as a result untila true application is downloaded. The applicationname displayed will be the address of the controllerfollowed by the model of the controller and “DefaultState”.For example, a CGM09090 controller whose rotaryswitches are set to 8 would have the default stateapplication name of “8-CGM09090 Default State”.The default state creates I/O points for allconnections on the input and output terminals.It assumes all Universal Inputs (UIs) are Nickeltemperature sensors. All Configurable Outputs(COs) are treated as Binary Outputs (BOs) with aninitial value of 0. 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 equipmentcontrollersYou commission MS/TP equipment controllers withthe CCT software using either MAP Gateway , aBTCVT, a ZFR wireless dongle, or in passthroughmode when connected to an NAE or NCE. Fordetailed information about commissioningfield controllers, refer to Controller Tool Help(LIT-12011147).

Note: You can use the Bluetooth connectionto Transfer to Computer (Upload) andcommission the controller, but you cannot usethe Bluetooth connection to Transfer to Device(Download).
