OPERATING MANUAL
PSEN op4F/H-A series
Automatic override restart
The OSSD output switching elements resume normal operation when the RESTART signal
goes low and not after 500 ms. With a timeout of 5 s on RESTART with 24 V an error is
generated, which blocks the light curtain.
The output signals switch to 24 VDC after a time period that represents the maximum value
between the reset time and the high restart time (greater than or equal to 500 ms). This time
period may lie between 500 ms and 5 s.
Once the override is ended, the OSSDs return to a normal operating state if the beams are
not interrupted.
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.
