Introduction to FX15 Controller
Figure 1: FX15 Classic Controller
The FX15 controller 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 FX15 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 onboard, real-time clock circuit is also
included to support the start-stop scheduling of equipment and real-time
based control sequences.
The FX15 controller can be integrated, as a slave device, in a distributed
control application managed by a master controller (FX16 Master
Controller or Master Display).

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
controller.
!
WARNING: Risk of Electric Shock. Disconnect or isolate all power
supplies before making electrical connections. More than one disconnect or
isolation may be required to completely de-energize equipment. Contact with
components carrying hazardous voltage can cause electric shock and may
result in severe personal injury or death.
AVERTISSEMENT: Risque de décharge électrique. Débrancher ou isoler
toute alimentation avant de réaliser un branchement électrique. Plusieurs
isolations et débranchements sont peut-être nécessaires pour-couper
entièrement l'alimentation de l'équipement. Tout contact avec des composants
conducteurs de tensions dangereuses risque d'entraîner une décharge
électrique et de provoquer des blessures graves, voire mortelles.
Mounting Instructions
To mount an FX15 controller:
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. Two types are available:
screw and cage clamp connectors. For details, see Ordering Codes.
Make terminations of the Supervisor Link, Expansion Bus, and
Remote Display 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.
