Installation Of Cables - Rechner Sensors EasyTeach KFA-5-ET Série Notice D'utilisation

Electrical Connection
The potential BE must be connected to the container potential! This connection should be made over
the shortest distance and routed with straight wire. (Shortening or lengthening of the cable is possible,
using a single-lead cable 0,25...1,5 mm
Mounting in / on containers or holders
made of metal (with connection to the
protective conductor potential of the
system).
KFS probe The BE connection must be established
via the evaluation unit.
KSL area sensors The BE connection must be established
via the evaluation unit.
KXS sensor with The BE connection is made between
the sensor and the system.
metal housing
KXS sensor with The BE connection must be made with the sensor or the evaluation unit.
• For the sensor use the M3-screw.
plastic housing
• For the evaluation unit use the soldering lug.
Attention:
For inductive loads, a corresponding protective circuit (e.g. freewheeling diode) must be
provided.

Installation of cables

Wiring of the sensor should be routed separately or screened from heavy conductor lines, as in ex-
treme cases inductive peak voltages can destroy the sensors despite the integrated protective circuit.
Screened cable or twisted lines are recommended, 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 nearby, e. g. high power walkie-talkies, or noise sources in the lower fre-
quency range, e. g. long, middle or shortwave transmitters should not be operated close to the sensors
or additional measures have to be taken in order to eliminate incorrect operation.
