Introduction to FX15
Figure 1: FX15 Classic
The FX15 is a high performance field controller of the Facility Explorer
system, specifically designed for commercial Heating, Ventilating, Air
Conditioning, and Refrigeration (HVACR) applications such as chillers
and rooftops, indoor packaged air conditioning units, air handling units,
and close control units.
The controller has 27 physical inputs and outputs and supports a wide
range of temperature sensors and actuating devices. Additional physical
inputs and outputs may be achieved by adding the XT/XP expansion
modules on the local Extension bus.
The FX15 controller is fully programmable or configurable, using the
FX Tools Pro software package, for a wide range of commercial
environmental control applications.
The FX15 controller is also available with a serial communication card
for integration into a Building Automation System with a LONWORKS®
or N2 Open bus network.
For stand-alone applications an on-board, real-time clock circuit is also
included to support the start-stop scheduling of equipment and real-time
based control sequences.
The FX15 can be integrated, as a slave device, in a distributed control
application managed by a master controller (FX16 Master Controller or
Master Display).
Optional accessories make the FX15 controller the state of the art
solution for the HVACR market:
• N2 Open, plug-in communication card
• LON, plug-in communication card
• user interface: Medium User Interface (MUI) and Large User
Interface (LUI)

Two different types of terminal connectors are available: spring clamp
or screw connectors. The screw connectors are included, while the
spring clamp connectors must be ordered separately. For details, see
Ordering Codes.
IMPORTANT: For installation with Class 2 inputs and outputs only, no
special mounting precautions are generally necessary. For use with one or
more line voltage outputs (above 30 V), installation as part of a UL 508A
industrial control panel may be required by the local building or electrical
authority. These controllers are presently UL Recognized as Temperature
Indicating and Regulating Equipment in accordance with UL 873. UL Listing as
Open Energy Management Equipment per UL 916 is pending.

North American Emissions Compliance
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 is
likely to cause harmful interference, in which case the user will be
required to correct the interference at his/her own expense.
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.

Detailed Procedures
Follow these instructions to properly install and connect the FX15.
!
WARNING: Risk of Electric Shock. Disconnect power supply before
making electrical connections. Contact with components carrying hazardous
voltage can cause electric shock and may result in injury or death.
Mounting Instructions
To mount an FX15:
1. Snap the controller onto the 35 mm (1.38 in.) rail for DIN rail
mounting. To release the controller, insert a screwdriver in Slots B
and lift the retaining clip. Since the retaining clip is spring-loaded,
you can also remove the controller without a screwdriver by
carefully pushing the controller up against the clip and then tilting
the top forward to release the top lug from the DIN rail.
2. Make wiring terminations with detachable connectors, which accept
1 x 1.5 mm2(0.002 in.2)/14 AWG cable. There are two types
available: screw and cage clamp connectors. For details, see
Ordering Codes.
Terminations of the Supervisor Link, Expansion Bus, and Remote
Display are made via the connectors provided with the controller.
3. Verify that the wiring has been correctly installed and that voltage
levels are appropriate for the various input signals according to the
application.
4. Set the jumpers and address switches of the controller as required.
For more information, see Jumper Details.
