along the whole measuring length. Mechanical
plays could compromise the proper counting;
•
the surface of the magnetic ring should be
cleaned periodically using a soft cloth to remove
dust, chips, moisture etc.
9 - Troubleshooting
The following list shows some typical errors that
could occur during installation and operation of the
magnetic measurement system.
Fault:
The system does not work (no pulse output).
Possible cause:
The ring or the sensor has been mounted
incorrectly.
A magnetic part has been inserted between the
sensor and the substrate. Only non-magnetic
materials are allowed between the sensor and
substrate.
The sensor touches the substrate because the
tolerance gap between the sensor and the
substrate is not met. Check the sensor active
side if damaged.
The sensor has been damaged by short circuit,
inversion of polarity or wrong connection.
Fault:
The measured values are inaccurate.
Possible cause:
The mounting tolerances are not thoroughly
met.
The connection cable runs near to high voltage
cable or shield is not connected properly. See
the section “6 - Electrical connections“.
The max. counting frequency of the receiving
device is too low.
A section of the magnetic substrate has been
damaged either mechanically or magnetically.
The measuring error is caused by torsion of the
machine structure. Check parallelism and
symmetry of machine movement.
