Troubleshooting
Errors
Errors that no longer guarantee the function of the safety door switch (internal errors) cause the safety outputs to be disabled immediately. Any
error that does not immediately affect the safe functionality of the safety door switch (e.g. too high ambient temperature, interference potential at
the safety outputs, cross-wire short) will lead to a warning message, disabling of the auxiliary output and a delayed shutdown of the safety outputs.
(Refer to Table 2.)
After fault rectification, the error message is reset by opening and re-closing the corresponding guard door.
Error warnings
A fault has occurred, which causes the safety outputs to be disabled after 30 minutes (LED "fault" flashes, see Table 2). The safety outputs initially
remain enabled. This signal combination, auxiliary 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.
