6.3. Restart mode
An opaque object detected by the beams causes the switching of
the OSSD outputs (i.e. the opening of the safety contacts -
BREAK condition).
The restart of the ESPE (i.e. the closing of the OSSD safety
contacts - SAFE condition) can be carried-out in two different
ways:
Automatic Restart:
when an opaque object is detected, the
ESPE enters in the BREAK condition. Then, after the opaque
object has been removed from the controlled area, the ESPE
begins its normal functioning again.
Manual Restart:
after the ESPE has detected an opaque object
in the controlled area, the light curtain begins its normal
functioning only by pressing the Restart button (TEST button) and
after the object has been removed from the controlled area.
