OCC
upancy position:
The load will automatically turn on when motion is
detected and automatically turn off when the selected time delay has
expired.
The push button may be used to manually turn ON/OFF the load
and time delay will also take effect.
VAC
ancy position:
The load will turn on ONLY when the push button is
used and automatically turn off when the selected time delay has expired.
The push button may be used to manually turn ON/OFF the load and time
delay will also take effect. If the time delay has expired and the load turns off,
the load will turn on again automatically if motion is detected within 30
seconds.
1.
Push Manual On/Off Button, if the load turns On; verify that
the
Ultrasonic
dial
is on high
and/ or the PIR switch is set to 100%
.
2.
Check the wiring connections
. Be sure the

e is present
.
3.
Switch may be in VACancy mode. Select the OCC position on the Mode
Switch if "Auto ON" is what's desired.
NOTE: There is a 1 minute warm-up time at initial power-up. The load
may turn on/off several times.
The Load does not turn On. LED does not flash regardless of motion:
The Load does not turn On
when LED indicator flashes and motion is
detected
:
1.
Push Manual On/Off Button, if the load turns On;
verify that the Ultrasonic
dial is on high and/ or the PIR switch is set to 100%.
2.
Check the wiring connections
. Be sure the
LOAD
wir
e is connected
.
3.
Switch may be in VACancy mode. Select the OCC position on the Mode
Switch if "Auto ON" is what's desired.
4.
Check the
Light
dial. The pointer indicates the light level the ambient light
needs to drop to before the load is automatically turned on.
The Load does not turn Off:
The Load turns on when its not desired:
1.
Motion may be detected. The time delay constantly restarts its countdown
after the last motion detected. To verify proper operation,
set
the Time
Delay
switches
to 15s (Test Mode) and make sure there is no motion (no
LED flashing). Tape may be used to cover the fresnel lens
and ultrasonic
cones
while testing.
2.
Check for significant heat source emitting within six feet (two meters) such
as high wattage light bulb, portable heaters or HAVC vents.
3.
If Manual operation of push-button is desired, select VAC mode on the
Mode Switch.
4.
If the sensor is installed in a small room, turn the Range dial lower
to avoid
false or unwanted detection from open window or door.
1.
Motion may be detected. The time delay constantly restarts its
countdown after the last motion detected.
2.
To verify proper operation, turn the Time Delay Knob to 15s (Test
Mode) and make sure there is no motion (no LED flashing). Tape may
be used to cover the fresnel lens while testing.
3.
Check for significant heat source emitting within six feet (two meters)
