The short-circuit proof diagnostic output OUT can be used for central visualisation or control tasks, e.g. in a PLC.
The diagnostic output is not a safety-related output.
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. After fault rectification, the error message is reset by opening and re-closing the
corresponding safety guard.
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).
