Height compensation of the load cells
1. Insert as many distance plates underneath the load cell with the lowest value as
necessary to equalize the output voltages.
6.3.2 Initial commissioning
1. Align the load cell site horizontally and level over the complete area.
2. Clean the load cell site and load cell base until both are absolutely clean.
3. Grease the contact surfaces of the force transfer elements with bearing grease.
4. Adjust the overload protection, if used, to ensure that it can still reliably sense transfer of
the required load. The overload protection must permit a rise in weight unhindered until
the setpoint weight is reached.
5. Ensure dirt and ice cannot build up on the overload protection.
6.3.3 Corner load adjustment
6.3.3.1 When is corner load adjustment necessary?
General
SIWAREX load cells, with the exception of the WL250 and WL260 series, are current-
calibrated as standard. Corner load adjustment is not necessary in the case of current-
calibrated load cells. Corner load adjustment is only necessary in the case of load cells that
are not current-calibrated or load cells that are not synchronized.
This may not apply to load cells that are available outside the standardized delivery
spectrum. For these load cell types, the relevant technical specifications apply.
Recommendation
Note
Carrying out a corner load adjustment
If you can apply the mass center of the product at different positions, it is possible that
different weights are displayed in each case. This reaction can occur in particular with the
following types of scale:
•
Platform scales
• Hopper scales where the filling with solid matter forms cones
We recommend that you carry out a corner load adjustment in such cases.
