6. 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
again only by pressing the Restart button (TEST button) and after the
object has been removed from the controlled area.
