Troubleshooting
If, after the installation there is an abnormally high wear and tear on
the sensor and/or the guiding power is unsatisfactory, check the fol-
lowing points::
Symptom
Cause
Corrective action
High wear and tear on
the sensor rollers.
The sensor rollers are
placed too close to the
conveyor belt or both rollers
are constantly touching the
conveyor belt.
Check the positioning of the sensor
rollers. These must be installed
about 6 mm away from the edge of
the conveyor belt.
Inadequate or, in fact,
no guiding power of
the tracker.
Check the positioning of the
tracker in the conveyor
system (see page 14 or
page 27). It is possibly
installed too close to a head
pulley.
The recommended installation
dimensions must necessarily be
complied with, see page 14 or
page 27
Greater wear and tear
of the trough rollers or
return rollers in the
tracker
The tracker is installed too
high in the conveyor
system.
Check the installation dimensions
given on page 21 for the lower unit.
Reposition or align it, if necessary.
For the upper unit, using conveyor
belt rollers with less diameter or
reinstalling them at another
position may help.
The tracker moves
unusually or does not
move at all
Check the bearings and the
installation position of the
tracker.
Correct the installation position
according to this installation
manual, if necessary. Defective
bearings need to be replaced.
