10 Safety edge adjustment
The pneumatic safety edge must be activated when the door is fully closed to acknowledge its correct function.
With use of a multimeter the sensitivity of the safety edge can be adjusted, that is done by turning the
adjustment screw counter clockwise until the signal is off and then clockwise until the signal is on and 1 -1½
turn more clockwise as safety precaution.
Furthermore the safety edge must be checked, that if the safety edge is activated, that the signal is back on
after no more then 7 second. If that is not the case the air relief screw must be adjusted counter clockwise until
it is archived.
