Coverage Patterns; Ultrasonic Sensor; Sensor Adjustment - wattstopper DSW-301 Installation Instructions Manual

COVERAGE PATTERNS

Coverage testing has been performed according to the NEMA WD 7 guideline. For
best performance, use in spaces not larger than 18' x 15'.
PIR Sensor
The sensor has a two-tiered, multi-
cell viewing Fresnel lens with 180
degree field of view. The red LED
on the sensor flashes when the PIR
detects motion.
Masking the Lens
Opaque adhesive tape is supplied
so that sections of the PIR sensor's
view can be masked. This allows
you to eliminate coverage in
unwanted areas. Since masking
removes bands of coverage,
remember to take this into account
when troubleshooting coverage
problems.

Ultrasonic Sensor

The sensor has two ultrasonic
transceivers operating at 40
kHz. Detection sensitivity can be
adjusted using the trimpot under
the ON/OFF buttons.
ADJUSTMENTS

Sensor Adjustment

Remove the wall plate. Remove the button cap by firmly squeezing together the
top sides of the button assembly. Gently pull it away from the unit.
When the adjustments are completed, replace the button cap by inserting its
hinges into the tabs on the main unit and then squeeze the top of the button while
pressing it into the unit. Reinstall the cover plate.
Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level control and
set the threshold:
1. Make sure the room is lit appropriately.
2. Put the sensor into TEST mode (see Time Delay switches). You have 10
minutes to complete the procedure.
