Unison® Heritage Contact and Fader Interface

Overview

This guide includes instruction for installation of the Unison Heritage Contact Interface and Unison
Heritage Fader Interface.

The Unison Heritage Contact Interface (model# UHCI) provides
convenient interface and integration to external devices by sending
and receiving contact closures. The interface enclosure provides
up to eight switch input and relay output connections. Closures are
configurable for either maintained or momentary operation.

The Unison Heritage Fader Interface (model# UHFI) provides
interface to external devices, such as faders or sensors, through a
variable 0-3.3 Vdc analog signal. The interface enclosure consists
of eight fader input connections and eight output lamp-driver
connections.

Step 2: Using the keyhole measurements in the graphic below, predrill and install two 1/4” (6mm)

bolts (bolts not provided).
Step 3: Install the enclosure onto the mounting bolts and secure.
Step 4: Notice the two screw holes on the bottom right and left of the rear panel. Use two screws

(not provided) to secure the enclosure the wall.

Rough-in Conduit and Wire

Conduit knockouts are provided on the left and bottom sides of the enclosure for installation
convenience. Wiring and termination for each interface type, Heritage Contact Interface and Heritage
Fader Interface, are similar. Pull the required wiring into the enclosure.

Terminate Wiring

Locate the termination kit shipped with the Interface packaging. This kit
includes a LinkPower pigtail, an Auxiliary Power pigtail and all required
connectors for use during installation.

Step 1: Terminate and connect LinkPower. LinkPower is topology

free and polarity independent. You may install LinkPower

in any combination of bus, loop, star or home-run.

a: Locate the LinkPower pigtail and two WAGO cage

clamp connectors from the termination kit.

b: Strip 3/8” (9-10mm) from the ends of each LinkPower

wire (both the provided pigtail and installed LinkPower
wire).

c: Use the WAGO cage clamp connector to connect the installed control wire to the

connectorized pigtail wires provided. Open the terminal levers on the WAGO
connector and insert the installed (typically black) Belden 8471 LinkPower wire and

the black lead from the LinkPower pigtail into the terminals.
d: Close the levers onto the wires.
e: Repeat for the installed (typically white) Belden 8471 LinkPower wire and remaining

pigtail wire using a new WAGO connector.
f: Install the LinkPower connector to J2 (NET) on the control board.

Step 2: Terminate and connect Auxiliary Power (24 Vdc) wiring.

a: Locate the Auxiliary Power pigtail and two WAGO cage clamp connectors from the

termination kit.
b: Strip 3/8” (9-10mm) from the ends of each Auxiliary wire (both the provided pigtail and

installed wire).
c: Use the WAGO cage clamp connector to connect the installed power wire to the

connectorized pigtail wires provided. Open the terminal levers on the WAGO

connector and insert the installed (typically black) 16 AWG (1.5mm

wire and the black lead from the pigtail into the terminals.
d: Close the levers onto the wires.

e: Repeat for the installed (typically red) 16 AWG (1.5mm

remaining pigtail wire using a new WAGO connector.
f: Install the Auxiliary connector, labeled “Power” (location J5 for Contact Interface and

J7 for the Fader Interface) on the control board.

Step 3: Terminate the ESD drain (ground) wire.

a: Strip 7/16” (11mm) from the end of the ground wire.
b: Loosen the terminal screw on a green/yellow terminal block. The green/yellow

terminal blocks are located at either end of the terminal strip. All field terminations

should be made to the right side of the terminal strip.
c: Insert the ground wire and tighten the screw onto the wire.

Interface Series

• When terminating a switch to a Contact Interface, each pair of terminations, either
Switch In or Switch Out, requires one switch and one common connection.

• When terminating a fader input to a Fader Interface, three wires are terminated
including a “PT” connection, “+3.3 Vdc” connection and a “Com” connection.

Note:

There is only one +3.3 Vdc terminal and one common (COM) terminal for fader inputs.
When multiple fader inputs are required, each terminal allows up to eight wires in the
single terminal. Additional connections can be bussed together to share the line using
WAGO connectors as required.

• When a lamp indication is required for the fader input (Fader Interface only), two
additional wires are required including an “LP” and a common (COM) connection.
Each lamp output terminal is functionally connected to a fader input terminal
(example: PT1 is factory wired and functionally connected to LP1).

Note:

The lamp voltage conducts from “V out” to the lamp outputs. When using polarity
sensitive indicators such as an LED, connect the anode to “V out” and the cathode to
the lamp “LP” connection.

a: Strip 7/16” (11mm) from the ends of each wire.
b: Loosen the terminal screw for each required termination.
c: Insert the wires into the corresponding terminal block number and tighten the screws

firmly onto the wires.
