15.2. Typical system times
Important!
The system times given are maximum values for one device.
Ready delay:
BR
The following applies to BR configuration:
After switching on, the device carries out a self-test for 5 s. The
system is ready for operation only after this time.
BP
The following applies to BP configuration:
After switching on, the device carries out a self-test for 0.5 s. The
system is ready for operation only after this time.
Turn-on time of safety outputs:
BR
The following applies to BR configuration:
The max. reaction time from the moment when the guard is closed
to the moment when the safety outputs switch on T
on
is 80 ms.
BP
The following applies to BP configuration:
The max. reaction time from the moment when the bolt tongue is
inserted to the moment when the safety outputs switch on T
on
is 80 ms.
BR
Simultaneity monitoring of safety inputs FI1A/FI1B:
If the safety inputs have different switching states for
longer than 50 ms, the safety outputs FO1A/FO1B will be switched off. The device switches to the fault state.
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 will be switched off after a
maximum of 50 ms.
This value applies to a single switch. The risk time increases by 10 ms for each additional switch in a chain.
Difference time:
The safety outputs FO1A and FO1B switch with a slight time offset. They both have the ON state at the
latest after a difference time of 10 ms.
