Tip!
We recommend the usage of the alignment aid of type AY-OS-LSR for the alignment of the transmitter
and receiver in the following.
1. Align the transmitter and receiver such that the first and the last beam are on the same axis in each case.
2. Move the transmitter and receiver until the green LED on the receiver illuminates continuously.
Models 14 mm and increased range:
1. Use the blue LED to check the signal strength.
2. If the blue LED illuminates continuously, the signal is weak.
3. Check the transmitter and receiver for interference and soiling.
4. Check again the alignment of both components until the blue LED extinguishes.
NOTICE
For further troubleshooting, see chapter LED displays and chapter Diagnostics / troubleshooting
3. Fix the transmitter and receiver in their current position.
Important!
Pay attention to the maximum tightening torque for fastening the transmitter and receiver to the
mounting bracket of 2.5 to 3 Nm.
Important!
If transmitters and receivers are mounted in areas that are subject to heavy vibration, it is necessary
to use vibration-attenuating mountings
7.11. Usage of deflection mirrors
Deflection mirrors make it possible to increase the size of the protective field. The light beams generated by the transmitter
can be deflected around several sides. The following figure shows an application in which two deflection mirrors are used
to obtain protection with a U-shape.
DANGER
Disabling of the safety function due to degradation on the mirror.
Dirty or damaged areas on the deflection mirror can disable the safety function.
Do not use deflection mirrors if soiling, the formation of condensed water or hoarfrost is to be
expected in the place of use.
Regularly clean the defection mirrors to prevent soiling and damage.
