BH 5910 / 200217 / 190A
With switch 10 the maximum number of LCs (Light curtains) is selected.
Open (unused) inputs (S_1/S_2 and S_3/S_4) have to be linked with a
wire bridge.
K1 and K2 can only be activated, if no LC is interrupted.
If both channels of an LC have different signals for more then 50 ms the
outputs K1 and K2 are switched off and the unit gives failure code 7. This
failure is stored and can only be reset by disconnecting the auxiliary supply.
The BH 5910 can be used on LCs of type 4 (IEC/EN 61 496-1) or type 2
with self test and crossfault monitoring.
The following function diagrams show the function of one LC. We pretend
that other connected LCs are not interrupted.
