Electrical connection
ATTENTION!
These magnetic sensors have been prepared for connection to DRO5. No modification of the
sensor connection (e.g. cable modification) is permitted.
Check all lines and connections before switching on the equipment.
5.6.1 Interference and distortion
All connections are protected against the effects of interference. The location should be selected to ensure
that no capacitive or inductive interferences can affect the sensor or the connection lines! Suitable wiring
layout and choice of cable an minimise the effects of interference (eg. interference caused by SMPS,
motors, cyclic controls and conductors).
5.6.2 Necessary measures:
The sensor should be positioned well away from cables with interference; if necessary a protective
screen or metal housing must be provided. The running of wiring parallel to the mains supply should be
avoided.
Contactor coils must be wired with spark suppression.
5.7
Maintenance
We recommend cleaning the magnetic strip's surface from time to time with a soft rag. This avoids dirt(dust,
chips, humidity ... ) sticking to the strip.
5.8
Trouble shooting
Below are some typical errors which may occur during installation and operation:
Magnetic strip incorrectly mounted (active surface must be mounted towards the sensor).
