Initial operation
Warning:
Before putting the SLS 78/R into operation for the first time on a power-driven production
machine, an experienced and commissioned person with suitable training must check the
entire setup and the integration of the opto-electronic protective device into the machine
control system.
Before connecting the supply voltage for the first time and while the transmitters and
receivers are being aligned, it must also be ensured that the outputs of the optical safety
device do not have any effect on the machine. The switching elements that finally set the
dangerous machine in motion must be safely switched off and secured from restarting.
The same precautionary measures apply after every change made to the optical
protective device, e.g. after repairs or during maintenance work, after an alignment or
after longer stopped periods.
Only after it has been determined that the opto-electronic protective device functions
correctly and without fault, including the safety sequential circuit, can it be integrated into
the machine’s control circuit!
