Sensor Adjustment; To Test Occupancy Sensors - wattstopper DT-355 Installation Instructions Manual

SENSO R ADJUSTMENT
The sensors are factory preset to allow for quick installation in most
applications. Verification of proper wiring or coverage, or customizing the
sensor's settings can be done using the following procedures. To make
adjustments, open the Front Cover with a small screwdriver.
There is a 30 second
warm-up period when
power is first applied.
Before making
adjustments, 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.
Set the Logic Configuration
and Time Delay to the
desired settings. See "Logic Configuration Chart", next page.

To Test Occupancy Sensors

1. Ensure the PIR and Ultrasonic Activity LEDs are enabled (DIP switch 7 ON)
and PIR Sensitivity is set to MAX (DIP switch #8 ON).
2. Ensure the Time Delay is set for Test Mode* using the "5 seconds/SmartSet"
setting. (DIP switches 4, 5, & 6 are OFF).
3. Ensure that the Light Level is at default (maximum). See the Light Level
Feature section of this document for instructions.
4. Ensure that the Ultrasonic Sensitivity trimpot is set to about 90%, clockwise.
5. Remain still. The red and green LEDs should not flash. The lights should
turn off after 5 seconds. (If not, see "Troubleshooting.")
6. Move about the coverage area. The lights should come on. Adjust the
Ultrasonic Sensitivity as necessary to provide the desired coverage (Green
LED indicates activation from the ultrasonic sensor).
When testing and adjustment is complete, reset DIP Switches and Light Level to
the desired settings, and replace the cover on the sensor.
* If you need to invoke the Test Mode and the DIP switches are already set for
5 seconds/SmartSet, toggle DIP switch #5 ON then back to the OFF position.
This provides a 5 minute test period. During the test period, the Time Delay
is only 5 seconds.
