The safety switch can be used in various operating modes.
}
Operation without safety device diagnostics
– Standard operating mode
After every restart the safety switch is in operation without Safety Device Diagnostics.
– No communication with Safety Device Diagnostics
– Activating/deactivating the guard locking is only via the signals S31 and S41
}
Operation with passive use of the Safety Device Diagnostics
– Safety switch supplies diagnostic data to Safety Device Diagnostics
– Activating/deactivating the guard locking is only via the signals S31 and S41
}
Operation with active use of the Safety Device Diagnostics
– Activate/deactivate the guard locking by a combination of a Safety Device Diagnostics
command and the status of the safety inputs S31 and S41 (S31 and S41 must have a
high signal).
The safety requirements are guaranteed by the signals S31 and S41 (the fieldbus for
Safety Device Diagnostics communication is not safe).

Operation with specified direction when activating/deactivating guard locking
A specified direction can be used to control switching of the guard locking status.
– Toggle: The safety switch changes the guard locking status (activated <-> deactiv-
ated) each time S31 and S41 are activated simultaneously.
– Force direction: The safety switch is selectively activated or deactivated by offset ac-
tivation of the rising edges at S31 and S41.
