the solenoid interlock, the switching condition of the solenoid interlock is maintained.
Error
Errors which no longer guarantee the function of the safety switchgear (internal errors) cause the safety outputs to
be disabled within the duration of risk. The fault is reset, when the cause is eliminated and bit 7 of the request byte
changes from 1 to 0 or the safety guard is opened. Faults at the safety outputs are only deleted upon the next
release, as the fault rectification cannot be detected sooner.
Fault warning
A fault that does not immediately endanger the safety function of the safety switchgear (e.g. too high ambient
temperature, safety output at external potential, cross-circuit) leads to delayed shutdown (see Table 2). This signal
combination, diagnostic output disabled and safety channels still enabled, can be used to stop the production
process in a controlled manner. An error warning is deleted when the cause of error is eliminated. If the fault
warning remains on for 30 minutes, the safety outputs are also switched off (red LED flashes, see Table 2).
Diagnostic error (warning)
If an error (warning) is signalled in the response byte, detailed fault information can be read out.
