Sensor Adjustment - Watt Stopper DT-300 Installation Instructions Manual

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 or coverage, or 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.
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".
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 Light Level is at default (maximum). Press and hold the
pushbutton for 5 seconds or until the Green LED flashes rapidly. Wait 10 seconds
for the flashing to stop.
3. Ensure that the Ultrasonic Sensitivity trimpot is set to about 70%, clockwise.
4. Remain still. The red and green LEDs should not flash. The lights should turn off
after 5 seconds. (If not, see "Troubleshooting.")
5. 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 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.
