4 Faults and alarms
4.2 List of faults and alarms
Remedy: Check the wiring of the fail-safe digital output (F-DO) and restart the test stop.
Note:
- the fault is withdrawn if the test stop is successfully completed.
- in the event of multiple test stop faults, the first one that occurred is shown. Once the test stop has been restarted
the next queued test stop fault will be signaled (if there is one).
F-DO: Failsafe Digital Output
A01774 SI Motion P1 (CU): Test stop for fail-safe digital outputs required
Message value: -
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: Control Unit (CU)
Reaction: NONE
Acknowledge: NONE
Cause: The time set in p10003 for the forced checking procedure (test stop) for the fail-safe digital outputs has been
exceeded. A new forced checking procedure is required.
After the next time the forced checking procedure is selected, the message is withdrawn and the monitoring time is
reset.
Note:
- this message does not result in a safety stop response.
- the test must be performed within a defined, maximum time interval (p10003, maximum of 8760 hours) in order to
comply with the requirements as laid down in the standards for timely fault detection and the conditions 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 enter the hazardous area and who are
depending on the safety functions correctly functioning.

Remedy: Carry out the forced checking procedure for the digital outputs.
The signal source to select the forced checking procedure is set via binector input p10007.

F-DO: Failsafe Digital Output

A01780 SBT When selected, the brake is closed
Message value: Following brakes are closed: %1 bin
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: None
Reaction: NONE
Acknowledge: NONE
Cause: When selecting the brake test or starting the brake test, not all of the brakes were open.
Alarm value (r2124, interpret binary):
Bit 0 = 1:
The internal brake is closed.
Bit 1 = 1:
The external brake is closed (p10230.5, p10235.5, p10202).
Note:
The alarm is also issued, if a brake has not been configured in p10202.
SBT: Safe Brake Test
See also: p10202 (SI Motion SBT brake selection), p10230 (SI Motion SBT control word), p10235 (SI Safety Control
Channel control word S_STW3B)
Remedy: Open all brakes and reselect the brake test (p10230.0, p10235.0).
