What does Maintenance signal output mean?
The cumulative energization time has exceeded the value set in the maintenance output timer (Pr. 503 Maintenance timer). This is a warning indicating that routine scheduled maintenance is due based on operating hours. While not a fault that stops operation, ignoring it can lead to component degradation and potential future failures.
