The safety light curtain LC1 monitors the access to the machine zone. The optical muting
sensors LM1 and LM2 are OR-linked with light curtain LC1 (muting function).
Both muting sensors are pulse controlled and must be active to carry out the muting
function (light curtain bypass).
The muting function requires that outputs Q1, Q2, Q4 have previously been switched
on. This means that the vision of LC1 has to be uninterrupted for power on.
Lamp L1 indicates the active muting state (static on). The expected Reset signal at S1 is
indicated by blinking of L1. L1 control complies with EN 60496-1.
Restart is possible after exiting the danger zone and pushing Reset button S3.
