FX-PCX3731-0

Issued December 5, 2014

Refer to the

QuickLIT website

for the most up-to-date version of this document.

Application

The FX-PCX3731 controller is a part of the Facility
Explorer FX-PC Series Programmable Controller family.
FX-PCX controllers expand the number of points
connected to an FX-PCA, FX-PCG, or FX-PCV
programmable controller or to an FX Supervisory
Controller.

FX-PCX controllers operate on an RS-485 BACnet

®

Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into the web-based Facility Explorer system.

Note:

At FX-PCT Release 10.1, a new capability was
introduced allowing FX-PCVs, FX-PCGs, and
FX-PCAs to communicate by using either the
BACnet or the N2 field bus networking protocol.
The operation of the FX-PCX Input/Output Module
is not affected by the selection of the BACnet or
the N2 protocol in the host controller.

North American Emissions
Compliance

Canada

This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur
du Canada.

United States

This equipment has been tested and found to comply with the
limits for a Class A digital device pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when this equipment
is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential
area may cause harmful interference, in which case the users
will be required to correct the interference at their own expense.

Installation

Observe these guidelines when installing a controller:

Transport the controller in the original container to
minimize vibration and shock damage.

Verify that all parts shipped with the controller.

Do not drop the controller or subject it to physical
shock.

Parts Included

one controller with removable terminal blocks (Power,
SA, and FC bus are removable)

one installation instructions sheet

Materials and Special Tools Needed

three fasteners appropriate for the mounting surface
(M4 screws or #8 screws)

one 20 cm (8 in.) or longer piece of 35 mm DIN rail
and appropriate hardware for DIN rail mount (only)

small straight-blade screwdriver for securing wires in
the terminal blocks

Mounting

Observe these guidelines when mounting an FX-PCX
controller:

Ensure the mounting surface can support the
controller, DIN rail, and any user-supplied enclosure.

Mount the controller horizontally on 35 mm DIN rail
whenever possible.

Mount the controller in the proper mounting position
(

Figure 1

).

Mount the controller on a hard, even surface
whenever possible in wall-mount applications.

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
requirements in

Table 9

.

Provide for sufficient space around the controller for
cable and wire connections for easy cover removal
and good ventilation through the controller (50 mm
[2 in.] minimum on the top, bottom, and front of the
controller).
