Sensor Adjustment - wattstopper DT-300 Installation Instructions Manual

SENSOR ADJUSTMENT

This unit is pre-set for basic operation as described
in this guide. Adjustment is optional.
The sensors are factory preset to allow for quick installation in most applications.
Verifi cation 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 fi rst applied.
Before making adjustments,
make sure the offi ce
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 airfl ow. Set the
Logic Confi guration and Time
Delay to the desired settings.
See "Logic Confi guration
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). Press the pushbutton for 5
seconds or until the Green LED fl ashes rapidly. Wait 10 seconds for the fl ashing
to stop.
4. Ensure that the Ultrasonic Sensitivity trimpot is set to about 90%, clockwise.
5. Remain still. The red and green LEDs should not fl ash. The lights should turn off
after 5 seconds. (If not, see "Troubleshooting.")
6. Move around within 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 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.
