Rechner Sensors EasyTeach KAS Serie Notice D'utilisation page 16

Electrical connection
Electrical connection EasyTeach by Wire (ETW)
NPN Normally open
PNP Normally open
EasyTeach versions have two modes:
By connecting the Teach input with UB+, the Teach mode is activated
By connecting the Teach input with GND, the Operating mode is activated
Electrical connection EasyTeach by Button (ETB) / Magnet (ETM)
NPN Normally open
PNP Normally open
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 frequen-
cy range, e. g. long, middle or short wave transmitters should not be operated close to the sensors or
additional measures have to be taken in order to eliminate incorrect operation.
