*2410143179C*

• Several 6 mm (1/4 in.) female spade terminals for input and output wiring

• Small straight-blade screwdriver for securing wires in the terminal blocks

Mounting

Observe these guidelines when mounting an FX-PCV.

Important: When the air supply to the VAV box is below 10°C (50°F), make sure that any

condensation on the VAV box, particularly on the damper shaft, does not enter the FX-

PCV electronics. Mount the FX-PCV vertically above the damper shaft to allow any shaft

condensation to fall away from the FX-PCV. Additional measures may be required in some

installations.

• Ensure the mounting surface can support the controller and any user-supplied enclosure.

• Mount the controller on a hard, even surface whenever possible.

• Use shims or washers to mount the controller securely and evenly on the mounting surface.

• Mount the controller in an area free of corrosive vapors and observe the ambient conditions in

the Technical specifications section.

• Provide sufficient space around the controller for cable and wire connections and good

ventilation through the controller. Leave a minimum of 50 mm (2 in.) around the top, bottom,

sides, and front of the controller.

• Do not mount the controller on surfaces prone to vibration, such as duct work, or in areas

where electromagnetic emissions from other devices or wiring can interfere with controller

communication.

On panel or enclosure mount applications, observe these additional guidelines:

• Do not install the controller in an airtight enclosure.

• Mount the controller so that the enclosure walls do not obstruct cover removal or ventilation

through the controller.

• Mount the controller so that the power transformer and other devices do not radiate excessive

heat to the controller.

To mount the FX-PCV controller:

1. Place the controller in the proper mounting position on the damper shaft so that the wiring

connections are easily accessible. Make sure the controller base is parallel to the VAV box

(perpendicular to the damper shaft). If needed, use a spacer to offset tipping of the FX-PCV

controller caused by the shaft bushings.

2. Secure the self-drilling No. 10 screw through the FX-PCV controller mounting slot with a power

screwdriver and 100 mm (4 in.) extension socket. Otherwise, use a punch to mark the position

of the shoulder washer, and then drill a hole into the VAV box using a 3.5 mm (9/64 in.) drill bit.

Insert the mounting screw, and tighten against the washer.

Important: Do not overtighten the screws, or the threads may strip. If mounting to the

VAV box, make sure the screws do not interfere with damper blade movement.

3. Locate the damper position using the typical marking on the end of the damper shaft.

Figure 1: Typical damper end shaft Iocns

4. Note the direction, clockwise (CW) or counterclockwise (CCW), required to close the damper.

Grasp the damper shaft firmly with pliers and either manually close the damper (for 90° boxes)

or manually open the damper (for 45° or 60° boxes).

5. Push down and hold the Manual Override button (Figure 2), and turn the FX-PCV controller

coupler until it contacts the mechanical end-stop at either the fully closed (90° boxes) or fully

open (45° and 60° boxes) position.

6. If the damper for a 90° box closes CCW, rotate the coupler to the CCW mechanical limit. If the

damper for a 90° box closes CW, rotate the coupler to the CW mechanical limit. The open end-

stop is automatically set for 90° boxes. For 45° and 60° boxes, hard stops must be provided

at both fully closed and fully open damper positions. By installing the FX-PCV controller at the

fully open position, the FX-PCV controller provides the open stop for 45° and 60° boxes. The

closed damper seal provides the fully closed stop.

7. All models are compact in size and are easily installed on VariableAir Volume (VAV) boxes with a

round shaft up to 13 mm in diameter,or a 10 mm square shaft.Tighten the square coupler bolt

to the shaft using an 8 mm (5/16 in.) wrench or 10 mm (3/8 in.) 12-point socket. Tighten to 11

to 15 N·m (100 to 130 lb·in).

8. Loop the pneumatic tubing to include a trap for condensation. Attach the tubing from the FX-

PCV controller to the VAV box pickup. The HIGH (red) tubing is connected to the inlet or high-

pressure side and the clear tubing to the low side (Figure 2).

9. Push the manual release button, and turn the actuator coupling manually to ensure that the

actuator can rotate from fully closed to fully open positions without binding.

10. Complete the mounting by rotating the damper to the fully open position.

CAUTION

Risk of Property Damage

Rotate the damper to the full-open position before starting the air handler. Failure to rotate the damper

to the full-open position may result in damage to the VAV box or ductwork when the air handler is

started.

CAUTION

Figure 4: SA bus terminal block wiring

FX-PCV Programmable Variable Air Volume Box Controllers Installation Instructions6

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. See Table 5 for more

information. The Sensor Port pin assignment is shown in Figure 5.

Figure 5: Pin number assignments for sensor, SA bus, and FC bus ports on FX-PCVs

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 bottom right of the FX-PCV.

Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the

terminal plug as shown in Figure 6. The middle terminal on the supply power terminal block is not

used. See Table 5 for more information.

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 FX-PCV 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 FX-PCV does not require an earth ground connection.

guidelines

Input and Output wiring guidelines

Table 2 provides information about the functions, ratings, and requirements for the FX-PCV input

and output terminals; and references guidelines for determining proper wire sizes and cable

lengths.

In addition to the wiring guidelines in Table 2, observe these guidelines when wiring FX-PCV inputs

and outputs:

• Run all low-voltage wiring and cables separate from high-voltage wiring.

• All input and output cables, regardless of wire size or number of wires, should consist of twisted,

insulated, and stranded copper wires.

• Shielded cable is not required for input or output cables.

• Shielded cable is recommended for input and output cables that are exposed to high

electromagnetic or radio frequency noise.

• Cable runs that are less than 30 m (100 ft) typically do not require an offset in the input/output

software setup. Cable runs that are over 30 m (100 ft) may require an offset in the input/output

software setup.
