    What to do if the Alarm LED is blinking on my socomec ATyS C35 Controller?
    • M
      Maria EllisSep 12, 2025
      If the Alarm LED is blinking on your Socomec Controller, it indicates a potential issue. First, verify that input 90-91 or any other input programmed to FAULT or NOT IN AUTO is not active. Also, check if there was a problem during a transfer order and validate the fault using the AUTO button. Finally, ensure that there are no ongoing faults.

    How to troubleshoot sources not detected on socomec ATyS C35?
    • E
      Elizabeth RobertsAug 21, 2025
      If the sources are not being detected by your Socomec Controller, start by verifying that the device is correctly powered on by checking the power LED. Then, make sure that the configured parameters of the controller match your specific installation setup.

    Why is the Source LED blinking on my socomec ATyS C35 Controller?
    • J
      Jason RobertsAug 23, 2025
      If the Source LED is blinking on your Socomec Controller, verify that the sources are within the voltage range configured through the DIP switch or communication settings. Also, ensure that the sources are cabled correctly and that the phase rotation is correct.

    What causes 'FAIL START' on a socomec ATyS C35?
    • J
      Joseph KirkAug 26, 2025
      The 'FAIL START' error on your Socomec Controller means the generator didn't start before the ST timer ended. To resolve this, check that the generator is functional, the genset start signal is correctly connected, and the ST timer is long enough for the generator being used.

    What does 'PHASE SEQ' mean on socomec ATyS C35?
    • L
      Lauren RushAug 28, 2025
      If your Socomec Controller displays 'PHASE SEQ', it means the phase sequence of source 1 (S1) and source 2 (S2) is different. To fix this, check your source sensing input cabling or disable the rotation check.

    What does 'PHASE ROT S1' mean on Socomec Controller?
    • H
      Heather RobinsonAug 30, 2025
      If your Socomec Controller shows 'PHASE ROT S1', it indicates that the phase rotation of source 1 does not match the phase rotation setting. Check the cabling of S1 and the settings used to resolve this.

    What does 'POS0 ERROR' mean on Socomec Controller?
    • M
      Michael MonroeSep 5, 2025
      If your Socomec Controller displays 'POS0 ERROR', it means the controller ordered a move to position 0, but it wasn't reached. Check the I/O connections and make sure the output signal time matches the RTSE being used.

    What does 'POS1 ERROR' mean on socomec ATyS C35 Controller?
    • J
      james45Sep 7, 2025
      If your Socomec Controller displays 'POS1 ERROR', it means the controller ordered a move to position 1, but it wasn't reached. Check the I/O connections and make sure the output signal time matches the RTSE being used.
