FEC26 Extended Temperature Field Equipment Controller

Installation Instructions

MS-FEC2611-0ET

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

Applications

The FEC26 extended temperature controller is part of
the Metasys® system Field Equipment Controller
(FEC) family. The FEC26 controller runs
pre-engineered and user-programmed applications
and provides the inputs and output s required to monitor
and control a wide variety of Heating, Ventilating, and
Air Conditioning (HVAC) equipment.

FEC 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 Metasys system.

IMPORTANT: In Metasys system smoke control
applications, use only the MS-FEU2610-0U and
MS-FEU2620-0U models that are UL Listed, UUKL
864 Listed, Smoke Control Equipment. For Metasys
system smoke control applications, you must refer to
the Metasys System UL 864 UUKL Ninth Edition

Smoke Control System Technical Bulletin
(LIT-12011252) for detailed requirements and

procedures for installing and operating UUKL 864
Listed Metasys system devices. Failure to meet the
requirements or follow the procedures in the

Metasys System UL 864 UUKL Ninth Edition Smoke
Control System Technical Bulletin (LIT-12011252)

can void the UUKL 864 listing for Smoke Control
Equipment.

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 cas e th e
users will be required to correct the interference at
their own expense.

Installation

Observe these guidelines when installing an FEC
extended temperature controller:

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

• Verify that all parts shipped with the FEC.

• Do not drop the FEC or subject it to physical shock.

Parts Included

• one FEC26 controller with removable terminal
blocks

• 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 mountin g an FEC:

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

• Mount the FEC on 35 mm DIN rail whenever

Figure 1: Controller Mounting Positions

Extended Mounting Clips, DIN Rail Channel, and

possible.

• Mount the FEC in the proper mounting position
(Figure 1).

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

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

• Mount the FEC in an area free of corrosive vapors
and observe the Ambient Conditions in the

Technical Specifications

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

• Do not mount the FEC 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 FEC in an airtight enclosure.

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

• Mount the FEC so that the power transformer and
other devices do not radiate excessive heat to the

controller.

section.

DIN Rail Mount Applications

DIN rail mounting is the preferred mounting method.
To mount an FEC on 35 mm DIN rail:

1. Securely mount a 20 cm (8 in.) or longer section of
35 mm DIN rail horizontal and centered in the
desired space so that the controller mounts in the
horizontal position shown in Figure 1.

2. Pull the two bottom mounting clips outward to the
extended position (Figure 2).

3. Hang the controller on the DIN rail by the hooks at
the top of the (DIN rail) channel on the back of the
controller (Figure 2), and position the controller
snugly against the DIN rail.

4. Push the bottom mounting clips inward to secure
the controller on the DIN rail.

To remove the FEC from the DIN rail, pull the bottom
mounting clips out to the extended position and
carefully lift the controller off the DIN rail.

FEC26 Extended Temperature Field Equipment Controller Installation Instructions2

Wall Mount Applications

To mount an FEC directly on a wall (or other flat vertical
surface):

1. Pull the two bottom mounting clips outward and
ensure they are locked in the extended positions
as shown in Figure 2.

3. Drill holes in the wall at the locations marked in
Step 2, and insert appropriate wall anchors in all
three holes (if necessary).

4. Hold the FEC in place, and insert the screws
through the mounting clips and into the holes.
Carefully tighten all of the screws.

2. Mark the three mounting hole locations on the wall
using the dimensions in Figure 2 and one of the
mount positions shown in Figure 1 (or ho ld th e
controller up to the wall/surface in a proper mount
position and mark the hole locations throug h th e
mounting clips.)

IMPORTANT: Do not overtighten the mounting
screws. Overtightening the screws may damage the
mounting clips.

Figure 4: FC Bus Terminal Block Wiring

Figure 5: SA Bus Terminal Block Wiring

CAUTION: Risk of Electric Shock.

Disconnect the power supply before
making electrical connections to avoid
electric shock.

IMPORTANT: Do not connect supply power to the
controller before finishing wiring and checking all
wiring connections. Short circuits or improperly
connected wires can result in damage to the
controller and void any warranty.

IMPORTANT: Do not exceed the controller
electrical ratings. Exceeding controller electrical
ratings can result in permanent damage to the
controller and void any warranty.

IMPORTANT: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.

IMPORTANT: Electrostatic discharge can damage
FEC components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the FEC controller.

SA Bus Terminal Block

The SA Bus terminal block is a brown, removable,
4-terminal plug that fits into a board-mounted jack.

Wire the removable SA Bus terminal block plugs on the
FEC and other SA Bus devices in a daisy-chain
configuration using 4-wire twisted, shielded cable as
shown in Figure 5. See Table 3 for more information.

For detailed information on configuring and wiring an
MS/TP Bus, Field Controller (FC) Bus, and Sensor
Actuator (SA) Bus, refer to the MS/TP Communications
Bus Technical Bulletin (LIT-12011034).

FEC Terminal Blocks and Bus Ports

See Figure 3 for terminal block and bus port locations
on the FEC26 extended temperature controller.
Observe the following guidelines when wiring an FEC
controller.

Input and Output Terminal Blocks

All of the fixed input terminal blocks are mounted on
the bottom of the FEC. The output terminal blocks are
mounted on the top of the controller. See Table 1 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.

Wire the removable FC Bus terminal block plugs on the
FEC, and other field controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 4. See Table 3 for more information.

Note: The Shield terminal (SHLD) on the FC Bus
terminal block is isolated and can be used to connect
the cable shields on the bus (Figure 4).

FC Bus Port

The FC Bus port on the front of the FEC is an RJ-12,
6-position modular jack that provides a connection for
the Bluetooth® Wireless Commissioning Converter,
ZigBee™ wireless dongle, or ZFR1811 Wireless Field
Bus Router.

The FC Bus port is connected internally to the FC Bus
terminal block. See Table 3 for more information. The
FC Bus Port pin assignment is shown in (Figure 6).
