5.5 How to detect a faulty Remote
There are two options for detecting a faulty remote:
1. The Control and Monitoring system (control PC in the Air Traffic Tower ) or the lucDMC tool, respectively, receives no
feedback from the lamp failure detection system, although the light is working.
2. The lights connected to the remote remain turned off when you try to turn it on.
3. Execute the self-test on SRU111 and SRU112.
Note
You should check if the respective light works correctly before replacing the remote. You can do so by connecting
a series circuit transformer.
