Installation of cables
Wiring of the
conductor lines, as in extreme cases inductive peak voltages can destroy the sensors
despite the integrated protective circuit. Screened cable or twisted lines are recom-
mended, especially for longer cable runs > 5 m. Direct control of electric light bulbs is to
be avoided, because during the switch-on moment cold current is many times the rated
current and can destroy the output stage of the sensor
Units with strong fields near by, e. g. high power walkie-talkies, or noise sources in the
lower frequency range, e. g. long, middle or short wave transmitters should not be oper-
ated close to the sensors or additional measures have to be taken in order to eliminate
incorrect operation.
