Typical system times

Important!
The system times given are maximum values for one device.
Ready delay:
In case of AR configuration the following applies: After switching on, the unit carries out a self-test for 10 s.
The system is ready for operation only after this time.
AR
In case of AP configuration the following applies: After switching on, the unit carries out a self-test for 0.5 s.
The system is ready for operation only after this time.
AP
Switch-on time of safety outputs:
In case of AR configuration the following applies: The max. reaction time from the moment when the guard is
locked to the moment when the safety outputs switch on T
AR
In case of AP configuration the following applies: The max. reaction time from the moment when the bolt
tongue is inserted to the moment when the safety outputs switch on T
AP
Simultaneity monitoring, safety inputs FI1A/FI1B: If the safety inputs have different switching states for longer
than 150 ms, the safety outputs FO1A/FO1B will be switched off. The device switches to fault state.
AR
Risk time according to EN 60947-5-3:
If the bolt tongue is pulled out of the interlocking module, the safety outputs FO1A and FO1B are deactivated after a max-
imum of 350 ms.
This value applies to a single switch. For each additional switch in a chain the risk time increases by 5 ms.
Difference time: The safety outputs FO1A and FO1B switch with a slight delay in relation to each other. They both have
the ON state at the latest after a difference time of 10 ms.
Time offset: The max. permissible time offset between switch-on of operating voltage UB and auxiliary voltage UA is 1 s.
