Electrical Connection; Installation Of Cables - Rechner Sensors EasyMount P3 Instrucciones

Electrical connection

3-wire sensors with binary output can be used in series or parallel connection, similar to mechanical
contacts. The type-typical voltage drop and the residual voltage U
ance with the number of sensors for series connection, must be noted. In the case of parallel connection
of sensors with FET-output, the first switched output takes over the total load current.

Series connection Parallel connection
Electrical connection EasyTeach by Wire (ETW)
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 Magnet (ETM)
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 extreme
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.
Units with strong fields nearby, 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 operated close to the sensors or additional
measures have to be taken in order to eliminate incorrect operation.
