FUNCTIONS

Manual Restart

After the ESPE has detected an opaque object in the controlled area, the light curtain
begins its normal functioning only after a proper signal pattern on RESTART input (pin 1,
usually connected to a normally open push button) and after the object has been
removed from the controlled area; see the restart timing diagram below:

The outputs go high after a time that is the maximum value between the recovery time
and the time of restart low (more or equal to 100 ms), so this time can be any between
0.1 s and 5 s.

The outputs go high after a time that is the maximum value between the recovery time
