TROUBLESHOOTING

For any unexpected operation

1.  Check DIP switch settings.
2.  Make sure the switches are set according to the defined settings in the DIP 

Switch Setting chart.

Lights do not turn on when entering the room.

Neither LED Flashes 

1.  Check that the circuit breaker has been turned back on.
2.  Check all sensor and power pack wire connections.
3.  Check for 24VDC input to the sensor between the red and black low voltage 

wires.

• 

If 24VDC is present, replace the sensor.

• 

If 24VDC is not present, check the high voltage connections to the power 

pack.

• 

If high voltage connections are good and high voltage is present, replace 

the power pack.

Red LED does not flash 

1.  When power is initially applied to the sensor, there is a warm-up period of 30 

to 60 seconds before the LED becomes active.

2.  Make sure PIR sensitivity is set to 100% (DIP switch #5 is in the “off” position).

Green LED does not flash 

Ultrasonic sensitivity setting may need to be increased. Turn adjustment trimpot 

clockwise  until the LED begins to flash when movement occurs.

Green LED is on steady 

Check ultrasonic sensitivity trimpot. Fully counterclockwise position is the override 

for the sensor. Turn trimpot clockwise until LED flashes only when movement 

occurs in the desired coverage area.

CAUTION

TURN POWER OFF AT THE CIRCUIT BREAKER 

 

BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
