The yellow MUT LED blinking on the Telemecanique XPSLCMUT1160 Muting Relay indicates a specific fault condition. Here are the possible causes and solutions for each scenario:
1. Yellow MUT LED blinking 2 times - Muting lamp in fault:
- Root cause: This could be due to a bad connection, a missing or faulty lamp, an incompatible LED lamp, or incorrect current in the lamp.
- How to solve: Check the lamp connection and ensure it is properly connected. Verify the voltage and power of the lamp (24 Vdc / 0.5 - 5 W). If necessary, replace the LED lamp with a filament lamp.
2. Yellow MUT LED blinking 3 times - Wrong selected value of the muting timeout:
- Root cause: The selected value of 30 seconds for the muting timeout may not be sufficient.
- How to solve: Select the "infinite" value for the muting timeout by wiring it accordingly.
3. Yellow MUT LED blinking 4 times - Wrong override configuration at power-up:
- Root cause: One muting photoelectric sensor in reflex mode may not be correctly adjusted.
- How to solve: Check the muting sensors and mirrors, ensuring they are properly fixed and adjusted according to the user manual.
4. No sensor S1-S2 connected on terminals 1 & 2:
- Root cause: This indicates that no sensor is connected, and the muting function does not operate at the light curtain. The "fail" and "Guard break" LEDs on the left side of the unit will be on.
- How to solve: Connect the photoelectric sensors (S1 and S2) as per the user manual specifications and the provided wiring diagram. Also, make sure to connect the muting lamp as it is monitored.
