Maintenance Procedures
Removing material accumulation
To ensure that the belt scale will provide optimal accuracy, periodically inspect the area
around the calibration weights and remove any material build-up.
The calibration weights must remain consistent to calibrate the scale correctly. If material
accumulates on top of them, the added weight will cause the calibration procedure to
produce poor results. The top surface of the calibration-weight supports must also be kept
clean for the scale to produce accurate results.
Material should not accumulate inside the crank body housings under normal operating
conditions, but it is a good idea to inspect them periodically.
1.
Remove any material build-up from the top of the calibration weights.
2.
Remove any material build-up from the top surface of the calibration-weight
supports between the calibration weights and the conveyor scale.
3.
Check inside the MWL crank body and inspect the worm gear drive: if material has
accumulated here, remove it with an air stream or other suitable device.
Greasing
On both crank bodies, the teeth of the drive plate are greased at the factory. They should
not require further greasing for a number of operations, depending on operating
conditions. Inspect the drive plate periodically, but apply grease only when it is required.
You may need to remove the bushed end-plates temporarily, to gain access to the teeth
and worm gear.
Note:
Before starting a calibration procedure, be sure to check that there is no
material accumulation in the three areas described below:
2. Top surface of calibration-
weight support
3. Inside crank body
1. Top surface of
calibration weights
(Bushed
end-plate)
Note:
The worm gear and notched plate are normally not accessible to the human
hand: do not force any foreign matter into the area during operation.
