8. Maintenance
The magnetic measurement system does not need any particular maintenance. It should be handled with
utmost care as any delicate electronic equipment. From time to time we recommend the following operations:
•
Periodically check the soundness of the structure and make sure that there are no loose screws.
Tighten them if necessary.
•
Check the mounting tolerances between the sensor and the magnetic tape. They must be meet all
along the whole measuring length. Mechanical movement may compromise the correct operation.
Wear of the machine may increase the tolerances.
•
The surface of the magnetic tape has to be regularly cleaned using a soft and clean cloth to remove
dust, chips, moisture etc.
9. Troubleshooting
The following list shows some typical faults that may occur during installation and operation of the magnetic
measurement system.
Fault:
The system does not work (no pulse output).
Possible cause:
•
The tape and/or the sensor are not installed properly. The active surface of the tape does not match
the sensitive part of the sensor or the sensor’s installation does not comply with the mounting
direction. For correct installation please refer to section
•
A magnetic component or a protective surface is interposed between the sensor and the tape. Only
non-magnetic materials are allowed between the sensor and the tape.
•
Installation does not meet the mounting tolerances between the sensor and the tape indicated in this
manual. During operation the sensor hit the surface of the tape (check whether the sensor sensitive
part is damaged). Or the sensor is mounted too far from the tape.
•
The sensor has been damaged by short circuit or wrong connection.
Fault:
The measured values are either inaccurate or not provided in the whole length.
Possible cause:
•
The mounting tolerances between the sensor and the tape are not met all along the whole measuring
length. For correct installation see section
•
The sensor is not installed properly on the tape.
•
The connection cable runs near high voltage cables or the shield is not connected properly.
•
Frequency error: the sensor is travelling too fast on the tape.
•
The frequency of the Master clock is set too high or too low and the transmission cannot be
synchronized correctly (see sections
•
A section of the magnetic tape has been damaged mechanically or magnetically along the measuring
length.
•
The measuring error is caused by a torsion in the machine structure. Check parallelism and symmetry
in the movement of the machine.
