LEGRAND Wattstopper CX-105 Instrucciones De Instalación página 3

Each Wattstopper BZ series power pack can supply power for up to 14
CX-105 sensors.
When using more sensors than this, multiple power packs are required.
Connect the low voltage:
• RED wire (+24VDC) from power pack to RED wire on sensor.
• BLACK wire from power pack to BLACK wire on sensor (Control Return) .
• BLUE wire from power pack to BLUE wire on sensor (Control Output 24VDC).

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 trimpot is 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.
