What to do if Douglas Lighting Controls WRS-2224 output relay(s) not tripping properly?

  John SandovalAug 7, 2025
  If the output relays on your Douglas Lighting Controls Scanner aren't tripping properly, several factors could be at play. First, ensure that the input voltage is within the required range of 22V to 30VAC by checking the input configuration, switching devices, connections, and power source. Also, if you're using non-default input switching devices, make sure the inputs are correctly configured. Another potential issue is the relay being part of another input group with conflicting input signals; if so, remove the relay from the other group. Finally, verify that the relay is included in the input group and re-program if necessary.

Why is TIME OUT not working on Douglas Lighting Controls WRS-2224 Scanner?
- M
  Mr. Bryan JohnsonAug 14, 2025
  If the TIME OUT function isn't working on your Douglas Lighting Controls Scanner, it might be due to several reasons. Ensure that you're using an appropriate input switching device, where the input is only ON during the TIME OUT period. Consider using a timer as an input instead of a switch. Also, verify that the relay group is programmed correctly and re-program if necessary. Finally, confirm that the TIME OUT function is assigned to only one all-inclusive group, as assigning it to multiple groups can cause issues.

What to do if Douglas Lighting Controls Scanner has flashing output LED(s) during NORMAL mode?
- M
  Miss Alexis VelezAug 23, 2025
  If the output LEDs on your Douglas Lighting Controls Scanner are flashing during normal mode, it could be due to a few reasons. A defective output relay might be the cause, in which case you should replace the relay. Another possibility is having two relays connected to the same output, with one ON and the other OFF; try resetting the relays and, if either relay is in another input group, remove it from that group. Lastly, check the wiring for any external AC current leaking into the circuit.

How to fix Douglas Lighting Controls WRS-2224 FLICK WARN not working?
- C
  Catherine McdonaldAug 30, 2025
  If the FLICK WARN feature isn't working on your Douglas Lighting Controls Scanner, it might be due to incorrect programming; in this case, check the programming and re-program if necessary. Also, if you're using HID lighting in the FLICK WARN group, switch to circuits with non-HID lighting.
