Replacing the optical cover
1.
First, clean the safety laser scanner from the outside, so that no foreign bodies
penetrate into the open device.
2.
Unscrew the fixing screws for the optical cover.
3.
Slowly and carefully detach the optical cover from the safety laser scanner. If the
optical cover seal sticks to the safety laser scanner, carefully detach the optical
cover using a screwdriver.
4.
If necessary, remove contamination from the sealing groove and the bearing sur‐
face of the safety laser scanner. Use residue-free plastic cleaners.
5.
During the following steps, wear the gloves supplied with the new optical cover.
6.
Take the new optics cover out of the packaging and remove the residual packag‐
ing.
7.
If the seal has come loose, place the seal in the slot provided in the optics cover.
8.
Carefully push the optical cover over the mirror. Make sure that the optical cover
does not touch the mirror.
9.
Place the optics cover onto the safety laser scanner. Make sure that the optics
cover rests over the whole area.
10. Screw on the optics cover with the new fixing screws. Tightening torque: 1.0 Nm …
1.2 Nm.
11. Make sure that the optical cover is clear of dirt and damage.
Put the safety laser scanner back into operation
1.
Properly remount the safety laser scanner.
2.
Reconnect all of the electrical connections to the safety laser scanner.
3.
Carry out optics cover calibration.
4.
Start the safety function using the Safety Designer.
5.
Check the effectiveness of the protective device.
°
Generally, the protective device is checked exactly as during commissioning.
°
If during the project planning the possible tolerances of the devices have
been considered and it is ensured that the configuration, wiring, or alignment
of the safety laser scanner have not been changed, a function test is suffi‐
cient.
