4. Slowly and carefully detach the optics cover from the safety laser scanner. If the
opt
ics cover’s seal sticks to the safety laser scanner, carefully detach the optics
cover using a screwdriver.
5. If necessary, remove contamination from the sealing groove and the bearing sur‐
face of the safety laser scanner. Use residue-free plastic cleaners.
6. Check whether the mirror on the motor is dirty and, if necessary, remove dirt using
an optic brush.
7. Set 1.0 Nm ... 1.2 Nm tightening torque on the torque wrench.
8. During the following steps, wear the gloves supplied with the new optics cover.
9. Take the new optics cover out of the packaging and remove the seal’s protective
cap.
10. Remove any packaging residue if necessary.
11. Carefully push the optics cover over the mirror. Make sure that the optics cover
does not touch the mirror.
12. Place the optics cover onto the safety laser scanner. Make sure that the optics
cover rests over the whole area without any gaps.

14. Tighten the screws using the set tightening torque.
15. Make sure that the optics cover is clear of dirt and damage.
Recommission the safety laser scanner as follows
1. Properly remount the safety laser scanner, see "Mounting", page 65.
2. Recreate all of the electrical connections to the safety laser scanner.
3. Carry out the optics cover calibration, see "Optics cover calibration", page 113.
4. Start the safety function using Safety Designer, see "Starting and stopping safety
function", page 110.
5. Check the effectiveness of the protective device.
°
Generally, the protective device is checked exactly as during commissioning,
see "Check during commissioning and modifications", page 116.
°
If, during project planning, the possible tolerances of the devices have been
considered and it is ensured that neither the configuration nor the wiring or
the alignment of the safety laser scanner have been changed, a function test
is sufficient, see "Thorough check of the principal function of the protective
device", page 62.
11.4 Replacing the safety laser scanner
If the safety laser scanner is damaged or defective, you must replace it.
DANGER
H
azard due to lack of effectiveness of the protective device
