DANGER
Hazard due to lack of effectiveness of the protective device
Hazard due to unexpected starting of the machine
By configuring the restart interlock for an OSSD pair, you can influence the restart
interlock behavior for the application.

Take account of the notes in the project planning chapter.
Restart interlock for the OSSD pair
The safety laser scanner has the following options for the restart interlock behavior for
the OSSDs:
•
Immediate restart without restart interlock
: If there is no longer an object in the protec‐
tive field, the safety laser scanner 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 safety laser scanner switches the OSSDs to the ON state.
•
Automatic restart after:
: If there is no longer an object in the protective field, the
safety laser scanner switches the OSSDs to the ON state after the configured
delay.
Activate external device monitoring (EDM)
An input must be configured for external device monitoring (EDM). This input must
be correctly connected to the electric control (
see "External device monitoring (EDM)",
).
If external device monitoring is activated, the safety laser scanner checks whether
voltage is applied at the external device monitoring (EDM) input after the OSSDs have
been switched off.
