What it means
Alarm A35014 is issued by the Terminal Module TM54F when the time set in p10003 for the forced checking procedure (test stop) of the fail-safe digital inputs/outputs has been exceeded, so a new forced checking procedure is required. The message does not result in a safety stop response and withdraws itself once the test has been selected again.
Why it appears
- The time set in p10003 for the forced checking procedure (test stop) for the digital inputs/outputs has been exceeded — a new forced checking procedure is required.
- The test must be performed within a defined, maximum time interval (p10003, maximum of 8760 hours) in order to comply with the requirements laid down in the standards for timely fault detection and the conditions used to calculate the failure rates of safety functions (PFH value).
- Operation beyond this maximum time period is permissible if it can be ensured that the forced checking procedure is performed before persons who are depending on the safety functions correctly functioning enter the hazardous area.
What to check
- Carry out the forced checking procedure for the digital inputs/outputs.
- Use the signal source that selects the forced checking procedure; it is set via binector input p10007.
Parameters the manual names
- p10003 (SI TM54F forced checking procedure timer) — sets the maximum time interval for the test stop; A35014 appears when this time is exceeded (maximum 8760 hours).
- p10007 (BI: SI TM54F forced checking procedure F-DI/F-DO signal source) — the binector input via which the signal source for selecting the forced checking procedure is set.
Acknowledging and restarting
No acknowledgment is required: after the next time the forced checking procedure is selected, the message is withdrawn and the monitoring time is reset.

Questions technicians ask
What does alarm A35014 mean on a SINAMICS drive?
It means the Terminal Module TM54F has not performed its forced checking procedure (test stop) for the fail-safe digital inputs/outputs within the time set in p10003, so a new test is due. The message does not result in a safety stop response.
How do I clear alarm A35014?
Carry out the forced checking procedure for the digital inputs/outputs; the signal source that selects it is set via binector input p10007. After the next time the procedure is selected, the message is withdrawn automatically and the monitoring time is reset.
How often must the TM54F test stop be performed?
Within the interval set in p10003, which may be at most 8760 hours, to comply with the standards for timely fault detection and the PFH value calculation. Operation beyond that period is permissible only if the test is performed before persons who depend on the safety functions enter the hazardous area.
