13.5 Course of the OSSD test over time
The safety laser scanner tests the OSSDs at regular intervals. To do this, the safety
laser scanner switches each active OSSD briefly (for max. 300 μs) to the OFF state and
checks whether this channel is voltage-free during this time.
Make sure that the machine’s control does not react to these test pulses and the
machine does not switch off.
