Applications
The FX-PCV1610/1620 controllers are part of the Facility Explorer
(FX-PC) family. FX-PCV controllers feature an integral 4 Nm damper actuator and Differential
Pressure Transducer. FX-PCV controllers run pre-engineered and user-programmed applications
required to monitor and operate a wide variety of VAV boxes.
The FX-PCV controllers operate on an RS-485 BACnet
Controllers (B-ASCs) and integrate into the web-based Facility Explorer system.

Page 6: Input And Output Terminals
Input and Output terminals The input spade terminals are located on the side of the FX-PCV near the device address switch. The output spade terminals are located on the opposite side of the controller near the power supply terminal block. See Table 2 for more information. FC bus terminal block The FC Bus terminal block is a blue, removable, 4-terminal plug that fits into a board-mounted jack. -
Page 7: Sensor Port
Sensor port The Sensor (SA Bus) port on the left side of the FX-PCV (Figure 2) is an RJ-12, 6-position modular jack that provides a connection for the VAV Balancing Tool, specified network sensors, or other SA Bus devices with RJ-12 plugs. The Sensor port is connected internally to the SA Bus terminal block. -
Page 8: Input And Output Wiring Guidelines
To wire the FX-PCV controller: 1. Terminate wiring per engineering drawings. 2. Wire network sensors and other devices to the FX-PCV'sSA Bus. 3. Wire the FC Bus in a daisy chain. 4. Ensure that the FX-PCV’s device address DIP switches are set to the appropriate device address.
