7.11.3 Further settings for some signals
Restart interlock for the OSSD pair
T
he following options are available for the restart behavior of the OSSDs:
•
Immediate restart without restart interlock: If there is no longer an object in the protec‐
tive field, the device switches the OSSDs to the ON state.
•
Restart interlock, reset required by input signal: If the operator activates the restart or
reset control switch, the device switches the OSSDs to the ON state.
•
Automatic restart after:: If there is no longer an object in the protective field, the
device switches the OSSDs to the ON state after the configured delay.
External device monitoring (EDM)
An in
put must be configured for external device monitoring (EDM). This input must be
correctly connected to the electrical control system.
If external device monitoring is activated, the device checks whether voltage is applied
at the external device monitoring (EDM) input after the OSSDs have been switched off.
If no voltage is applied at the input after the OSSDs have been switched off, the device
changes to the interlocked state and does not switch the OSSDs back to the ON state.
Signal level
F
or some non-safe output signals, you can select whether the signal is output with
HIGH or with LOW:
•
Setting Hi: The output is normally in LOW state. If the signal is active, the output
switches to HIGH state.
•
Setting Lo: The output is normally in HIGH state. If the signal is active, the output
switches to LOW state.
