SENSOR ADJUSTMENT
This unit is pre-set for basic operation as described
The sensors are factory preset
to allow for quick installation in
most applications. Verification
of proper wiring, coverage,
and customizing the sensor's
settings can be done using the
following procedures. To make
adjustments, open the Front
Cover by pulling on the cover tab.
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 Time Delay to the desired settings. See "DIP Switch Setting".
To Test Occupancy Sensors
1.
Ensure the Time Delay is set for Test Mode* using the "Test Mode/20 minutes"
setting (DIP switches 1,2 & 3 are off).
2.
Ensure that the Ultrasonic Sensitivity trimpot is set to about 70%, clockwise.
3.
Ensure that the Light Level is at default (maximum). See the Light Level
Feature section of this document for instructions.
4.
Remain still. The green LED should not flash. The lights should turn off after 5
seconds. (If not, see "Troubleshooting.")
5.
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.
* Test Mode is a temporary state that starts when you first set the sensor's DIP
switches for the "Test Mode/20 minutes" (switches 1, 2, 3 OFF). If you need to
invoke the Test Mode and the DIP switches are already set for Test Mode/20
minutes, toggle DIP switch 1 ON then back to the OFF position. This provides a 10
minute test period. During the test period, the Time Delay is only 5 seconds.
