Maximum Muting Time Exceeded
Beckhoff · TwinSAFE Logic FB
What does FB MUTING Bit 7 mean?
The maximum allowed duration for the muting function has been exceeded. This indicates that an object has remained in the muting zone for longer than permitted, or the 'MaxMutingTime' parameter is set too short for the process. This fault ensures that muting is not active indefinitely, which would compromise safety and results in a safety shutdown.
Complete Troubleshooting Guide
- 1
Identify why an object is remaining in the muting zone for an extended period (e.g., conveyor jam, slow-moving product, operator intervention).
- 2
Review and potentially adjust the 'MaxMutingTime' parameter in the FB MUTING configuration if the process legitimately requires a longer muting duration.
- 3
Ensure muting sensors are functioning correctly and reliably detecting the presence/absence of objects.
- 4
Check for any external conditions or interlocks that might be inadvertently prolonging the muting state.
