TROUBLESHOOTING
CAUTION
USE PROPER SAFETY PRECAUTIONS WHEN
WORKING WITH OR NEAR HIGH VOLTAGE
Lights will not turn on:
1. Verify the lens is not masked in the direction being tested (see Masking).
2. Adjust Sensitivity settings up if needed (DIP switches #7 & 8).
3. Verify power pack and sensor connections are correct and secure.
4. Check for +24VDC at RED wire from the power pack to sensor.
• If present, the problem may be with the sensor. Try another sensor (if
available).
• If there is no voltage, see Power Pack High Voltage Checklist, below.
Lights will not turn off:
1. Check that Time Delay settings are correct (DIP switches #1 – 6).
2. Decrease Sensitivity settings if needed (DIP switches #7 & 8).
3. Verify power pack and sensor connections are correct and secure.
4. Disconnect BLUE wire on power pack from sensor.
• If the lights turn off, the problem may be in the sensor. Turn Sensitivity
and Time Delay to minimum and allow the sensor to time-out.
- If the lights turn off, the sensor is working correctly. See Unwanted
Sensor Activations, below. Go through the Sensor Adjustment
process again.
• If the lights stay on, the problem may be in the power pack. See Power
Pack High Voltage Checklist, below.
Power Pack High Voltage Checklist:
CAUTION: Use proper high voltage precautions.
1. Check that power pack high voltage wire connections are correct and
secure.
2. Check that the power pack is rated at the correct voltage.
3. Check that there is high voltage going into the power pack.
4. Try another power pack (if available).
Unwanted sensor activations (LED flashes):
Possible causes
1. People moving or walking outside of the desired coverage area, but in
view of the sensor and within it’s range (see Coverage Patterns and
Placement).
2. HVAC vents with heavy air flow.
Possible solutions
1. Masking (see Masking).
2. Setting the Sensitivity lower.
3. Relocating the sensor.
Sensor Override:
If the sensor fails, set DIP switch #6 to OFF. This overrides the sensor and
sets the circuits to “on”.
