Application
The FX-PCA2611-0 Advanced Application Programmable
Controller is part of the Facility Explorer Programmable
Controller (FX-PC) family. The FX-PCA26 Series
controllers run pre-engineered and user-programmed
applications and provide the inputs and outputs required
to monitor and control a wide variety of HVAC equipment.
FX-PCA26 controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Advanced Application Controllers (B-AACs) and integrate
into Johnson Controls®and third-party BACnet systems.
FX-PCA26 controllers include an integral real-time clock,
which enables the controllers to monitor and control
schedules, calendars, and trends, and operate for
extended periods of time as stand-alone controllers when
offline from the system network.
Switchable Communications
Protocols
By default, the FX-PC family controllers and network
sensors communicate using the standard BACnet®
protocol, based on the ANSI/ASHRAE 135-2004.
The BACnet protocol is a standard for ANSI, ASHRAE,
and the International Standards Organization (ISO) for
building controls.
FX-PCG, FX-PCX, and FX-PCV controllers are BTLtested and listed as BACnet Application Specific
Controllers (B-ASCs). FX-PCA field controllers are
BTL-listed as BACnet Advanced Application Controllers
(B-AACs). The NS Series Sensors are BTL-listed as
BACnet Smart Sensors (B-SSs).
Release 10.1 of FX-PCT and later can be used to switch
the Field Bus communications protocol in FX-PC
Controllers to be either the standard BACnet
Master-Slave/Token-Passing (MS/TP) or the N2 protocol.
BACnet MS/TP is the default communications protocol
for all new controllers. Switchable communications
protocols provide a cost-effective upgrade and
modernization path for customers with existing N2
controllers. The Modernization Guide for Legacy N2Controllers (LIT-12012045) and the controller-specific
documentation provide installation and commissioning
support and include tips for efficient and safe
replacement. Refer to the N2 Compatibility Options
chapter of the Controller Tool Help (LIT-12011147) for
information about mapping N2 Objects in controllers with
switchable communications protocols.
The N2-capable FX-PC controllers can be used as
functional replacements for legacy N2 controllers. The
N2-capable FX-PC controllers:
•have the I/O quantities and characteristics of the
FX-PC family controllers
•must be programmed with FX-PCT, which has
programming capabilities that are similar (but not
identical) to HVACPro, GX9100, GPL, and other
legacy tools
•support SA Bus devices
•support FX-WRZ wireless sensors from the controller
using the FX-WRZ7860 receiver when configured for
BACnet MS/TP communication
The N2-capable FX-PC controllers:
•do not support Zone Bus (for example, TMZ sensors
and M100 actuators)
•do not support pass through in the commissioning
mode
•do not support remote downloading or commissioning
using BACnet routing

The 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 the
controller, and other SA bus devices in a daisy-chain
configuration using 4-wire twisted, shielded cable as
shown in Figure 5. See Comm Bus and Power Supply
Terminal Block Rating and Requirements Table for more
PWR terminal can be used to connect (daisy
chain) the 15 VDC power leads on the SA bus.
FC Bus Port
The FC bus port on the front of the controller is an RJ-12,
6-position modular jack that provides a connection for
the FX-BTCVT Bluetooth® Commissioning Converter,
ZigBee®wireless dongle, or FX-ZFR1811 Wireless Field
Bus Router.
The FC bus port is connected internally to the FC bus
terminal block. See Comm Bus and Power Supply
Terminal Block Rating and Requirements Table for more
information. The FC bus port pin assignment is shown in
Figure 6.
Note: When the FX-PCA is configured for N2 network
communication, the FC bus port is not used.
The Sensor (SA Bus) port on the bottom of the controller
is an RJ-12, 6-position modular jack that provides a
connection for the Bluetooth Commissioning Converter,
the VAV Balancing Tool, specified network sensors, or
other SA Bus devices with RJ-12 plugs. When the FEC
FX-PCA is configured for N2 network communication,
you must download and commission the controller using
the SA Bus port.

Figure 7: 24 VAC Supply Power Terminal Block Wiring
Note: The supply power wire colors may be different on
transformers from other manufacturers. Refer to
the transformer manufacturer’s instructions and
the project installation drawings for wiring details.
Important: Connect 24 VAC supply power to the
controller and all other network devices so
that transformer phasing is uniform across
the network devices. Powering network
devices with uniform 24 VAC supply power
phasing reduces noise, interference, and
ground loop problems. The controller does
not require an earth ground connection.
Wireless Network Applications
When configured for BACnet MS/TP communication, the
FX-PCA2611 controller can also be installed in a wireless
application using an FX-ZFR1811 Wireless Field Bus

Setup and Adjustments
Setting the Device Addresses
FX-PC Series controllers are master devices on MS/TP
(SA or FC) buses. Before operating FX-PCA2611
controllers on a bus, you must set a valid and unique
device address for each controller on the bus. You set
an FX-PCA2611 controller's device address by setting
the positions of the switches on the DIP switch block at
the top of the controller (Figure 3). Device addresses 4
through 127 are the valid addresses for these controllers.
The DIP switch block has eight switches numbered 128,
64, 32, 16, 8, 4, 2, and 1 (Figure 9). Switches 64 through
1 are device address switches. Switch 128 is a mode
switch that enables a controller to operate on an FX-ZFR
Series Wireless Field Bus. Switch 128 must be set to Off
for all hard-wired SA and FC bus applications. Set switch
128 to ON for wireless FC bus applications only.
Figure 9: Device Address DIP Switch Block Set to
Address 21
To set the device addresses on FX-PC controllers:
1. Set all of the switches on the address DIP switch
block (128 through 1) to Off.
2. Set one or more of the seven address switches (64
though 1) to ON, so that the sum of the switch
numbers set to ON equals the intended device
address. See Table 6 for valid device addresses.
Set the highest number switch that is less than or
equal to the intended device address to ON. Then
continue setting lower numbered switches until the
total equals the intended address. For example, if the
intended device address is 21, set switch 16 to ON
first, then set switch 4 ON, followed by switch 1
(16+4+1= 21). See Figure 9.
3. Set switch 128 to ON only for controllers on a FX-ZFR
Wireless Field Bus application. For all hard-wired SA
and FC bus applications, ensure that switch 128 is
set to Off.
Note: Do not connect a controller with switch 128
set to ON to an active (hard-wired) SA or FC
bus. When a controller with switch 128 set to
ON and a device address from 4 to 127 is
connected to a wired field bus, the entire field
bus is rendered inoperable until the controller
is disconnected or switch 128 is set to Off.
Note: FX-PC Series controllers ship with switch 128 ON
and the remaining address switches off rendering
the controllers wired slave devices, which do not
operate on MS/TP buses, but do not interfere with
bus operation. Set a valid and unique device
address on the controller before applying power
to the controller on the bus.
Refer to the FX-ZFR Wireless Field Bus SystemTechnical Bulletin (LIT-12011660) for more
information on device addresses in wireless
applications.
4. Set a unique and sequential device address for each
of the controllers connected on the SA or FC bus
starting with device address 4.
To ensure the best bus performance, set sequential
device addresses with no gaps in the device address
range (4, 5, 6, 7, 8, 9, and so on). The controllers do
not need to be physically connected on the bus in
their numerical device address order.
5. Write each controller's device address on the white
label below the DIP switch block on the controller's
cover.
Table 6 describes the FC bus and SA bus devices
addresses for FX-PC Series controllers
communications bus applications.
Refer to the FX-PC Series Controllers MS/TP
Communications Bus Technical Bulletin
(LIT-12011670) or MS/TP Communications Bus for
BCM System Technical Bulletin (LIT-12011908) for
more information on controller device addresses and
how to set them on MS/TP buses.

operate on MS/TP buses.
Valid for MS/TP Master controllers on wireless
FC Buses only.
Note: Do not connect a controller with
switch 128 ON to an active
(hard-wired) SA or FC bus. When a
controller with switch 128 ON and a
device address from 4 to 127 is
connected to a wired field bus, the
entire field bus is rendered inoperable
until the controller is disconnected or
switch 128 is set to Off.
Setting the N2 Controller Address to
be Greater than 127
N2-configured controllers support the full range of
possible N2 device addresses provided by the N2 protocol
standard (1-255). However, these controllers require
special configuration for addresses above 127.
Use the following instructions for controllers greater than
127.
Note: Before you perform this procedure, make sure
that your controller has been converted from
BACnet to N2 protocol first.
Note: This special configuration is required because
controller addresses above 127 were originally
intended for use with the Wireless Field Bus
system.
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 FX-PCT tool connection at the FX-PC
controller’s SA bus , download the firmware and
controller application file. The download process
asks to confirm switching the communication protocol
to N2.
7.Click OK.
8.After the download is finished, disconnect the 24
VAC supply to the FX-PC controller.
9.Set the address switch segment labeled 128 to ON.
10. Reattach the FC Bus connector to the FX-PC
controller.
11. Reconnect the 24 VAC supply to the FX-PC
controller.
Removing the Controller Cover
Important: Electrostatic discharge can damage
controller components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid
damaging the controller.
Important: Disconnect all power sources to the
controller before removing cover and
changing the position of any jumper or the
EOL switch on the controller. Failure to
disconnect power before changing a jumper
or EOL switch position can result in damage
to the controller and void any warranties.
The controller cover is held in place by four plastic latches
that extend from the base and snap into slots on the
inside of the housing cover.
To remove the controller cover:
1. Place your fingertips under the two cover lift tabs
(Figure 3) on the sides of the housing cover and
gently pry the top of the cover away from the base to
release the cover from the two upper latches.
2. Pivot the top of the cover further to release it from the
lower two latches.
3. Replace the cover by placing it squarely over the
base, and then gently and evenly push the cover on
to the latches until they snap into the latched position.
Figure 10: FX-PCA2611-0 with Cover Removed
Showing EOL Switch and Jumper Positions
2. Determine if the controller must be set as a
terminating device on the bus.
Note: Refer to the FX-PC Series Controllers MS/TP
Communications Bus Technical Bulletin
(LIT-12011670) or MS/TP Communications
Bus for BCM System Technical Bulletin
(LIT-12011908) for detailed information
regarding EOL termination rules and 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 a
terminating device on the bus, set the EOL switch to
Off.
When a controller is connected to power with its EOL
switch set to ON, the amber EOL LED on the
controller cover is lit.

bus. See Figure 10 for the EOL switch location. The
default EOL switch position is Off.
Figure 11: End-of-Line Switch Positions
To set the EOL switch on an FX-PCA2611 controller:
1. Determine the physical location of the controller on
the FC bus.
Risk of Electric Shock: Disconnect supply power to
the controller before attempting to adjust the Binary
Output Source Power Selection Jumpers. Failure to
disconnect the supply power may result in electric shock.
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation de l'controller avant tout
réglage du Binary Output Source Power Selection
Jumpers. Le non-respect de cette précaution risque de
provoquer une décharge électrique.

Important: Do not connect an external power source
to a when the BO power source jumper is
in the internal power (INT) position.
Connecting external power to a BO that
sources internal power can damage the
controller and void any warranties.
The BO source power selection jumpers determine
whether a BO provides internal power (sourced from the
controller) to the output load (INT position) or requires
an external power source (EXT position) for the output
load. Figure 12 shows an example of a controller BOs
and the associated power selection jumpers to the right
of the BOs terminal block.
Figure 12: Example Binary Outputs and the
Associated Source Power Jumper Positions
Setting the current loop jumper to the Enabled position
(Figure 13) connects an internal 100 ohm resistor across
the UI terminals, which maintains the 4-20 mA current
loop circuit even when power to the controller is
interrupted or off.
Important: Current Loop jumpers must be in the
Disabled (default) position for all UIs that
are not set up to operate as 4-20 mA analog
inputs.
Table 7 identifies the current loop switches associated
with each UI on the FX-PCA2611-0 controller.

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

Setting Up a Local Display
FX-PCA2611-0 models do not have an integral display,
but can be connected to an FX-DIS1710 Local Controller
Display. For detailed information on setting up and
operating either an integral user interface or a remotely
connected FX-DIS1710 display, refer to the FX-DIS LocalController Display Technical Bulletin (LIT-12011666).
Commissioning the Controllers
You commission MS/TP controllers with the Facility
Explorer Programmable Controller Tool (FX-PCT)
software, either via a Bluetooth® Wireless Commissioning
Converter, a ZFR wireless dongle, or in router mode when
connected to an FX Supervisory Controller. Refer to
Controller Tool Help (LIT-12011147) for detailed
information on commissioning controllers.
Troubleshooting the Controllers
Observe the Status LEDs on the front of the controller
and see LED Status and Description Table to troubleshoot
the controller. To troubleshoot an integral or local
controller display, refer to the FX-DIS Local ControllerDisplay Technical Bulletin (LIT-12011666).
