Mechanical Prerequisites
Mount mechanical equipment in accordance with the
instructions given in separate manual. Check weighed
and carrying idlers in the weigher influential zone for
correct alignment and out-of-round.
Influential zone
All weighed idlers and three carrying idlers upstream
and downstream of weighing station.
Alignment
Raise idlers in the influential zone to approx. 3...5 mm
above remaining idlers. Align then against one
another to a height difference below 0.2 mm.
Depending on idler set equipment, idlers have to be
aligned in various points.
Out-of-round
The out-of-round error of idlers in the weigher
influential zone must not exceed 0.2 mm.
Securement
After alignment, secure idler sets against
displacement.
Mark idlers and sets to avoid mistakes during
maintenance.
Influences
Incorrect alignment entails a zero point error which is
normally compensated during calibration.
However, changes in belt tension increase the error
size.
For this reason, ensure correct alignment and
constant belt tension for accurate weighing.
Maintenance
If idlers are dismounted for maintenance work to be
effected, make sure that they are remounted in their
former locations.
Electrical Prerequisites
Run and connect cables as described in Chapter
DETAILS.
