Preventing Mutual Interference Between Adjacent Devices - Leuze electronic MLC 500 Original Operating Instructions

6.1.5

Preventing mutual interference between adjacent devices

If a receiver is located in the beam path of an adjacent transmitter, optical crosstalk, and thus erroneous
switching and failure of the protective function, may result.

mounting

NOTICE
Possible impairment of the availability due to systems mounted close to each other!
The transmitter of one system can influence the receiver of the other system.
Ä Prevent optical crosstalk between adjacent devices.
Ä Mount adjacent devices with a shield between them or install a dividing wall to prevent mutual interfer-
ence.
Ä Mount the adjacent devices opposite from one another to prevent mutual interference.
