Step 5: Thread the appropriate washer and nut (two sizes included) onto either
the Light Sensor Head or the extension adaptor (if used), securing it in
place.
Terminating Remote Light Sensor Head Control Wiring
Termination is available at the Controller for up to two Light Sensor Heads
(labeled “Primary Sensor” and “Optional Sensor”). When remote Light Sensor
Heads are installed, follow these instructions to terminate the control wiring at
both the Light Sensor Head and the Controller.
Step 1: Terminate the incoming wire from the Controller to the Light Sensor
Head leads using wire nuts or other wire termination (not provided).
a: Strip each wire to the appropriate length, depending on the wire nut
or other wire termination used (wire nuts are not provided).
b: Twist the installed (typically black) Belden 8471 incoming wire and
the black lead from the Light Sensor Head together and secure
using a wire nut or other wire termination.
c: Repeat for the installed (typically white) Belden 8471 wire and
remaining wire lead.
Step 2: Terminate the incoming wire pairs from the remote Light Sensor
Head(s) to the controller.
a: At the controller, strip 5/8” (9-10mm) of insulation from the ends of
each installed Light Sensor Head wire.
b: Using a small 1/8” (3,35mm) flat blade or #1 Phillips screwdriver,
loosen the terminals on the “Primary Sensor” and “Optional Sensor”
connectors found on the Light Sensor Controller.
c: Insert the black (typical) wire from the first Light Sensor Head wire
pair into terminal “1” of the “Primary Sensor” connector.
d: Insert the white (typical) wire from the first Light Sensor Head wire
pair into terminal “2” of the “Primary Sensor” connector.
e: Repeat this process for the second wire pair, if installed, to the
“Optional Sensor” connector.
Set Station Configuration
The Light Sensor Controller has on-board switch and mode button settings that
determine functionality, space assignment, and sensor address.
Rotary Switch Assignments
Two rotary switches on the rear panel of the
sensor controller provide for Space and
Address assignment.
By default, these switches are set to Space 1,
Address 1. Each sensor and station in a space
must have a unique address setting and
commands are shared by all devices within a
space.
