OPERATING MANUAL
PSEN op2H-A series
The condition for the override is that the light curtain must be in a SAFE STATE and at least
one muting sensor must have been interrupted.
If this condition is met, the user interface shows “override call status”
and both the red LED
on the OSSDs and the LEDs for the alignment function flash.
OVERRIDE CALL
STATUS
As a result, the override request will only be accepted if the signals at the OVERRIDE X
inputs comply with the timings shown below.
The override function is ended automatically if any of the following conditions is present:
•
All muting sensors are deactivated (with a T-muting configuration).
•
All muting sensors are deactivated and no beams are interrupted (with an L-muting
configuration).
•
The preset time limit has elapsed.
•
The requirements for activation are no longer met (e.g. an override input is deactivated).
7.8.1 Override mode
It is possible to activate the override inputs: Level or edge.
As shown in the diagram below, the two types of activation sequence for the override are
recorded in the external inputs:
•
Activated by level:
The override remains activated until both contacts are closed and
at least one muting sensor has been 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.
