13.3 Course of the OSSD test over time
The safety camera sensor tests the OSSDs at regular intervals. To do this, the safety
c
amera sensor switches each OSSD briefly to the OFF state and checks whether this
channel is voltage-free during this time.
Make sure that the machine controller does not respond to these test pulses and the
machine does not switch off.
