TROUBLESHOOTING

Loads do not operate as expected.

LEDs don’t light, display 

is off

1. Check to see that the the sensor is connected to the DLM local Network.
2. Check for 24VDC input to the sensor: Plug in a different DLM device at the sensor location. 

If the device does not power up, 24VDC is not present.
•  Check the high voltage connections to the room controller.
•  If high voltage connections are good and high voltage is present, recheck DLM local 

Network connections between the sensor and the room controller.

The wrong lights are 

controlled

1. Configure the sensor to control the desired lights using the Push n’ Learn adjustment 

procedure.

LEDs turn ON and OFF but 

load doesn’t switch

1. Make sure device is not in PnL.
2. Check load connections to room controller.
