Service Mode
To override all sensor functions, set DIP switch 6 to the OFF position. The red
LED will come on and stay on for the duration of the override.
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, next page. And 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.
Isolated relay not functioning properly:
CAUTION: Use proper high voltage precautions, if applicable.
1. Check that Time Delay settings are correct (DIP switches #1 – 6).
2. Check Sensitivity setting. Also see, Unwanted Sensor Activations, next
page.
3. Verify all wire connections from sensor are correct and secure.
4. Check that there is voltage to the Isolated Relay.
5. Check for +24VDC at RED wire from the power pack to sensor.
6. Use an ohmmeter to check the function of the Isolated Relay:
• Turn off the power connected to Isolated Relay wires (if applicable).
• With motion in front of the sensor’s lens, check that the
connection between the BROWN and RED wires is open.
• With motion in front of the sensor’s lens, check that the
connection between the ORANGE and RED wires is closed.
