FAC2611-0U Advanced Application Field EquipmentController Installation InstructionsMS-FAC2611-0U

Part No. 24-10143-01620, Rev. —Software Release 8.1Issued March 2018

ApplicationThe FAC2611 Advanced Application Field EquipmentController (FAC) is part of the Metasys® system FieldEquipment Controller family. The FAC26 Seriescontrollers run pre-engineered and user-programmedapplications and provide the inputs and outputs requiredto monitor and control a wide variety of HVAC equipment.

FAC26 field controllers operate on an RS-485 BACnet®MS/TP Bus as BACnet Advanced Application Controllers(B-AACs) and integrate into Johnson Controls® andthird-party BACnet systems.

FAC26 controllers include an integral real-time clock,which enables the controllers to monitor and controlschedules, calendars, and trends; and operate forextended periods of time as stand-alone controllers whenoffline from the system network.

Important: The MS-FAC2611-0U model is used inMetasys Release 8.1 smoke controlapplications and is UL 864 UUKL/UUKLC10th Edition Smoke Control Listed. Youmust refer to theMetasys® System UL 86410th Edition UUKL/ORD-C100-13 UUKLCSmoke Control System Technical Bulletin(LIT-12012487) for detailed requirementsand procedures for installing,commissioning, and operating UL 864UUKL/UUKLC Listed Metasys systemdevices. The UL 864 UUKL/UUKLC listingfor Smoke Control Equipment is voided if(1) you do not use the required softwaretools at the required versions; or (2) you donot meet the requirements or do not followthe procedures as documented in theMetasys® System UL 864 10th EditionUUKL/ORD-C100-13 UUKLC SmokeControl System Technical Bulletin(LIT-12012487).

Switchable CommunicationsProtocolsThe Family Controllers and network sensors communicateusing the standard BACnet protocol, based on theANSI/ASHRAE 135-2004. The BACnet protocol is astandard for ANSI, ASHRAE, and the InternationalStandards Organization (ISO) for building controls.

Most FEC, VMA16, VMA18,IOM field controllers areBTL-listed as BACnet Application Specific Controllers(B-ASCs). FAC field controllers and the VMA1930 FieldController are BTL-listed as BACnet Advanced ApplicationControllers (B-AACs).

You can use Release 10.3 and Release Module (RM)10.2 of the Controller Configuration Tool (CCT) to switchthe Field Bus communications protocol in supported FEC,FAC and VMA controllers to be either the standardBACnet MSTP or the N2 protocol. All new controllers useBACnet MSTP as the default communications protocol.Switchable communications protocols in the MSTPmodels provide a cost-effective upgrade andmodernization path for customers with existing N2controllers.

The N2-capable FEC Family Controllers can be used asfunctional replacements for legacy N2 controllers. TheN2-capable FEC Family Controllers:• have the input and output (I/O) quantities and

characteristics of the FEC Family Controllers• must be programmed with CCT, which has similar,

but not identical programming capabilities asHVACPro, GX9100, GPL, and other legacy tools

• support SA Bus devices• are available in Buy American versions (most models)• are listed for UL864 UUKL/UUKLC (some models).

N2 is supported as part of theMetasys® 10th Editionlisting for Smoke Control System Equipment.

1FAC2611-0U Advanced Application Field Equipment Controller Installation Instructions

The N2-capable FEC family controllers:• do not support Zone Bus (for example, TMZ sensors

and M100 actuators) or XT-Bus (System 91) devices(for example, XT, XTM, and XP modules)

• do not support a wireless connection to the N2 bus• do not support NxE passthrough

FAC Terminal Blocks and Bus PortsSee Figure 3 for terminal block and bus port locations onthe FAC2611 controller. Observe the following guidelineswhen wiring a controller.

Input and Output Terminal BlocksOn most field controller models, all of the fixed inputterminal blocks are mounted on the bottom of thecontroller, and the output terminal blocks are mountedon the top of the controller. See Table 3 for moreinformation about I/O terminal functions, requirements,and ratings.

FC Bus Terminal BlockThe FC Bus terminal block is a blue, removable,4-terminal plug that fits into a board-mounted jack.

Wire the removable FC bus terminal block plugs on thecontroller, and other controllers in a daisy-chainconfiguration using 3-wire twisted, shielded cable asshown in Figure 4. See Comm Bus and Power SupplyTerminal Block Rating and Requirements Table for moreinformation.

Figure 4: FC Bus Terminal Block Wiring

Note: The FC bus Shield (SHLD) terminal is isolatedand can be used to connect (daisy chain) theshields for FC bus wiring.

SA Bus Terminal BlockThe SA Bus terminal block is a brown, removable,4-terminal plug that fits into a board-mounted jack.

Wire the removable SA Bus terminal block plugs on thecontroller, and other SA bus devices in a daisy-chainconfiguration using 4-wire twisted, shielded cable asshown in Figure 5. See Comm Bus and Power SupplyTerminal Block Rating and Requirements Table for moreinformation.


Figure 5: SA Bus Terminal Block Wiring

Note: The SA PWR terminal supplies 15 VDC. The SAPWR terminal can be used to connect (daisychain) the 15 VDC power leads on the SA bus.

FC Bus PortThe FC bus port on the front of the controller is an RJ-12,6-position modular jack that provides a connection forthe Bluetooth® Commissioning Converter, or ZFR/ZFRPro Wireless Field Bus Router.

The FC bus port is connected internally to the FC busterminal block. See Comm Bus and Power SupplyTerminal Block Rating and Requirements Table for moreinformation. The FC bus port pin assignment is shown inFigure 6.

Note: When the FAC is configured for N2 networkcommunication, the FC bus port is not used.

Figure 6: Pin Number Assignments for Sensor, SABus, and FC Bus Ports on Field Controllers

Sensor PortThe Sensor (SA Bus) port on the bottom of the controlleris an RJ-12, 6-position modular jack that provides aconnection for the VAV Balancing Tool, specified networksensors, or other SA Bus devices with RJ-12 plugs.

The Sensor port is connected internally to the SA busterminal block. See Comm Bus and Power SupplyTerminal Block Rating and Requirements Table for moreinformation. The Sensor Port pin assignment is shownin Figure 6.

Supply Power Terminal BlockThe 24 VAC supply power terminal block is a gray,removable, 3-terminal plug that fits into a board-mountedjack on the top right of the controller.

Setup and Adjustments

Setting the Device AddressesMetasys® field controllers are master devices on MS/TP(SA or FC) buses. Before operating field controllers ona bus, you must set a valid and unique device addressfor each controller on the bus. You set a field controller'sdevice address by setting the positions of the switcheson the DIP switch block at the top of the controller (Figure3). Device addresses 4 through 127 are the validaddresses for these controllers.

The DIP switch block has eight switches numbered 128,64, 32, 16, 8, 4, 2, and 1 (Figure 9). Switches 64 through1 are device address switches. Switch 128 is a modeswitch that enables a controller to operate on a ZFR/ZFRPro Series Wireless Field Bus. Set switch 128 to Off forall hard-wired SA and FC bus applications.

Figure 9: Device Address DIP Switch Block Set toAddress 21

Note: Metasys® field controllers ship with switch 128ON and the remaining address switches offrendering the controllers wired slave devices,which do not operate on MS/TP buses, but do notinterfere with bus operation. Set a valid andunique device address on the controller beforeapplying power to the controller on the bus.

To set the device addresses on Metasys® fieldcontrollers:

1. Set all of the switches on the address DIP switchblock (128 through 1) to Off.

2. Set one or more of the seven address switches (64though 1) to ON, so that the sum of the switchnumbers set to ON equals the intended deviceaddress. See Table 6 for valid device addresses.

Set the highest number switch that is less than orequal to the intended device address to ON. Thencontinue setting lower numbered switches until thetotal equals the intended address. For example, if theintended device address is 21, set switch 16 to ONfirst, then set switch 4 ON, followed by switch 1(16+4+1= 21). See Figure 9.

3. Set switch 128 to OFF for all hard-wired SA and FCbus applications.

Note: Do not connect a controller with switch 128set to ON to an active (hard-wired) SA or FCbus. When a controller with switch 128 set toON and a device address from 4 to 127 isconnected to a wired field bus, the entire fieldbus is rendered inoperable until the controlleris disconnected or switch 128 is set to Off.

4. Set a unique and sequential device address for eachof the controllers connected on the SA or FC busstarting with device address 4.

To ensure the best bus performance, set sequentialdevice addresses with no gaps in the device addressrange (4, 5, 6, 7, 8, 9, and so on). The controllers donot need to be physically connected on the bus intheir numerical device address order.

5. Write each controller's device address on the whitelabel below the DIP switch block on the controller'scover.

Table 6 describes the FC bus and SA bus devicesaddresses for Johnson Controls® MS/TPcommunications bus applications.


Refer to the MS/TP Communications Bus TechnicalBulletin (LIT-12011034) for more information oncontroller device addresses and how to set them onMS/TP buses.

Setting the N2 Controller Address tobe Greater than 127N2-configured controllers support the full range ofpossible N2 device addresses provided by the N2 protocolstandard (1-255). However, these controllers requirespecial configuration for addresses above 127.

Use the following instructions for controllers greater than127.Note: Before you perform this procedure, make sure

that your controller has been converted fromBACnet to N2 protocol first.

Note: This special configuration is required becausecontroller addresses above 127 were originallyintended for use with the Wireless Field Bussystem.

1. Disconnect the 24 VAC supply from the controller.2. Remove the FC Bus connector from the controller.3. Set the address switch set to the desired N2 address.4. Set the address switch segment labeled 128 to OFF.5. Reconnect the 24 VAC supply to the controller.6. Using an SA bus connection, download the firmware

and controller application file. The download processasks to confirm switching the communication protocolto N2.

7. Click OK.8. After the download is finished, disconnect the 24

VAC supply to the controller.9. Set the address switch segment labeled 128 to ON.

10. Reattach the FC Bus connector to the controller.11. Reconnect the 24 VAC supply to the controller.

controller components. Use properelectrostatic discharge precautions duringinstallation, setup, and servicing to avoiddamaging the controller.

Important: Disconnect all power sources to thecontroller before removing cover andchanging the position of any jumper or theEOL switch on the controller. Failure todisconnect power before changing a jumperor EOL switch position can result in damageto the controller and void any warranties.

The controller cover is held in place by four plastic latchesthat extend from the base and snap into slots on theinside of the housing cover.

To remove the controller cover:

1. Place your fingertips under the two cover lift tabs onthe sides of the housing cover and gently pry the topof the cover away from the base to release the coverfrom the two upper latches.

2. Pivot the top of the cover further to release it from thelower two latches.

3. Replace the cover by placing it squarely over thebase, and then gently and evenly push the cover onto the latches until they snap into the latched position.

Setting the End-of-Line (EOL) SwitchEach field controller has an EOL switch, which, when setto ON, sets the controller as a terminating device on thebus. See Figure 10 for the EOL switch location. Thedefault EOL switch position is Off.

Figure 11: End-of-Line Switch Positions

To set the EOL switch on a field controller:

1. Determine the physical location of the field controlleron the FC bus.

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

Note: Refer to the MS/TP Communications BusTechnical Bulletin (LIT-12011034) for detailedinformation regarding EOL termination rulesand EOL switch settings on FC buses.

3. If the controller is a terminating device on the FC bus,set the EOL switch to ON. If the controller is not aterminating device on the bus, set the EOL switch toOff.

When a controller is connected to power with its EOLswitch set to ON, the amber EOL LED on thecontroller cover is lit.

Setting the Input and OutputJumpers

Risk of Electric Shock: Disconnect supply power tothe field controller before attempting to adjust the BinaryOutput Source Power Selection Jumpers. Failure todisconnect the supply power may result in electric shock.

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 risque deprovoquer une décharge électrique.

Binary Output (BO) Source PowerSelection Jumpers

Risk of Electric Shock: Disconnect supply power tothe field controller before attempting to adjust the BinaryOutput Source Power Selection Jumpers. Failure todisconnect the supply power may result in electric shock.

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 risque deprovoquer une décharge électrique.

Important: Do not connect an external power sourceto a binary output (BO) when the BO powersource jumper is in the internal power (INT)position. Connecting external power to aBO that sources internal power can damagethe controller and void any warranties.

The BO source power selection jumpers determinewhether a BO provides internal power (sourced from thefield controller) to the output load (INT position) orrequires an external power source (EXT position) for theoutput load. Figure 12 shows an example of a controllerBOs and the associated power selection jumpers to theright of the BOs terminal block.

Figure 12: Example Binary Outputs and theAssociated Source Power Jumper Positions


UI Current Loop JumpersThe current loop fail-safe jumpers are on the circuit boardunder the controller cover near the UI terminals (Figure10). When a UI is defined (in the system software) as a4-20 mA Analog Input and the UI’s current loop jumperis in the Disabled (default) position (Figure 13), the 4-20mA current loop circuit opens whenever power to thecontroller is interrupted or off.

Figure 13: Current Loop Jumper Positions

Setting the current loop jumper to the Enabled position(Figure 13) connects an internal 100 ohm resistor acrossthe UI terminals, which maintains the 4-20 mA currentloop circuit even when power to the controller isinterrupted or off.

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

Table 7 identifies the current loop switches associatedwith each UI on the FAC2611 controller.
