OPERATING MANUAL PSEN op4F/H-A series
Normal override restart
The OSSD outputs switch to normal operation when the RESTART signal goes low and not
after 500 ms. With a timeout of over 5 s an error is generated, which blocks the light curtain.
The output signals switch to 24 V DC after a time period that represents the maximum value
between the reset time and switched restart (greater than or equal to 500 ms).This time
period may lie between 500 ms and 5 s.
Once the override is ended and if the beams are not interrupted, the light curtain switches to
an interlock state, after which a restart must be performed in order to resume a normal
operating state.
OVERRIDE STATE: This is an output signal which provides the user with information as to
whether the override inputs are active and the override conditions are present.
