11.3 Maintenance

The LIMAX2 shaft information system requires little maintenance. On the occasion of regular elevator inspection and maintenance do the
following:
Optical inspection of proper alignment between sensor and band. Worn off material indicates possible alignment flaws. Check

for proper guiding of the band along the complete travel distance. Correct if necessary as described in the installation procedure
above.
Optical inspection of the band. Check for abrasions or other mechanical damages. Small mechanical damages (scratches, dents,

or even small chips) do not interfere with the measuring performance at all.
However, a pre-damaged band is more exposed to mechanical stress and is prone to further wear.
Check for proper tension of the band. If the mounting was via a flute, the tension can decrease over time. Readjust if necessary.

Inspect the polymer guide for wear. Clean if dust and dirt have accumulated between polymer guide and sensor case. The poly-

mer guide is a wear part. Replace if necessary.
Clean the band. Use a dry and clean cloth. Begin at the head of the hoistway drive down the complete travel distance pulling the

magnet band through a dry cloth.
