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).
