Error Muting Lamp

ABB · AC500-S Safety

What does C003 mean?

An error has been detected concerning the muting lamp for an AOPD (Active Opto-electronic Protective Device). A faulty muting lamp (indicated by S_MutingLamp = FALSE) prevents the proper visual signaling of the muting state, which is crucial for operator safety. This can lead to an unsafe condition if the lamp fails to indicate muting correctly, potentially allowing access to a hazardous area during muting.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Verify the S_MutingLamp input signal to the function block is receiving the expected status.

  2. 4

    If the lamp is functional, check the configuration parameters related to muting lamp monitoring within the function block.
