Ambient conditions
Correction factor Fc
Mist
0.25
Vapors
0.50
Dust

ATTENTION!
Loss of the safety function due to the formation of condensed water
Condensed water can disable the device’s protective function
Avoid sudden temperature fluctuations in the place of use
Clean your system regularly.
7.7. Use of several safeguards (multiple systems)
WARNING
Malfunction, loss of the safety function due to optical interference
Light beams from other transmitters may be received due to incorrect positioning.
Transmitters and receivers must be positioned such that the beams emitted by a transmitter can
be received only by the related receiver.
If several systems are used, it must be ensured that the function of the transmitters and receivers is not degraded.
The following positioning examples can be used:
