Figure 5: SA Bus Terminal Block Wiring
Note:
The SA PWR terminal supplies 15 VDC. The SA
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
Terminal Block Rating and Requirements Table
for more
information. The FC bus port pin assignment is shown in
Note:
When the FX-PCA is configured for N2 network
communication, the FC bus port is not used.

Bus and FC Bus Ports on Controllers
Sensor Port
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.
An FX-DIS1710 Local Controller Display also can be
connected to the SA Bus port.
The Sensor port is connected internally to the SA bus
terminal block. See
Terminal Block Rating and Requirements Table
for more
information. The Sensor Port pin assignment is shown
in
Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a board-mounted
jack on the top right of the controller.
Wire the 24 VAC supply power wires from the transformer
to the HOT and COM terminals on the terminal plug as
shown in
. The middle terminal on the supply
power terminal block is not used. See
Power Supply Terminal Block Rating and Requirements
Table
for more information about the Supply Terminal
Block.
