WARNING: TURN THE POWER OFF AT THE

CIRCUIT BREAKER BEFORE WIRING.

Each Wattstopper BZ series power pack can supply power for up to

6 CX-100 sensors.

When using more sensors than this, multiple power packs are

required.

FIRST–connect the low voltage:

• RED wire (+24VDC) from power pack to VIOLET wire on sensor.

• BLACK wire (Return) from power pack to GREEN wire on sensor.

Wiring a SINGLE LIGHTING LOAD CONTROLLED BY

OCCUPANCY ONLY–connect:

• BLUE wire from power pack to YELLOW wire on sensor.

Wiring a SINGLE LIGHTING LOAD CONTROLLED BY

OCCUPANCY, DEPENDENT ON LIGHT LEVEL (AMBIENT

LIGHT)–connect:

• BLUE wire from power pack to BLUE wire on sensor.

Wiring ONE LIGHTING LOAD FOR OCCUPANCY CONTROL,

AND A SECOND LOAD FOR OCCUPANCY AND LIGHT LEVEL

(AMBIENT LIGHT) CONTROL–connect:

• BLUE wire from power pack to YELLOW wire on sensor.

• BLUE wire from slave pack to BLUE wire on sensor.

• BLACK wire from slave pack to GRAY wire on sensor.

Wiring the ISOLATED RELAY: (The Isolated Relay is rated for 1A

@24VDC)

Connect the wires necessary to the application that requires this

output.

• RED (Common) (must be used for proper operation).

• BROWN (Normally Closed)–Open when occupancy is detected.

• ORANGE (Normally Open)–Closed when occupancy is detected.

The sensors are factory preset to allow for quick installation

in most applications. However, verification of proper wiring or

coverage, or customizing of the sensor's settings can be done

through the following steps.

Before starting, make sure the office furniture is installed, lighting

circuits are turned on, and the HVAC systems are in the overridden/

on position. VAV systems should be set to their highest airflow.

There is a warm-up period when power is first applied to the

sensor for one to two minutes.

1. For testing, set the Time Delay to minimum, 15 seconds. See

chart for DIP switch configurations.

2. Ensure that the Sensitivity and Light Level trimpots are set to

maximum, fully clockwise.

3. Remain still. The lights should turn off after approximately 15

seconds (If not, see Troubleshooting).

4. Set the desired Time Delay.

5. Readjust the angle of the sensor if necessary.

Light Level feature:

The Light Level feature holds lights off upon initial entry into the space if adequate ambient light exists. It will not turn the lights off if

they are on. Adjust the Light Level during daylight hours when ambient light in the area is adequate. Avoid mounting the sensor too

close to lighting fixtures.
