Installation
4.2 Installing the base plate and elastomer bearing
Procedure
1. Determine which load cell has the lowest load.
– Connect load cells in the junction box.
– Disconnect the load cell cables SIG+ and SIG-.
– Connect a supply voltage to the load cells via a SIWAREX weighing module.
– Measure the output voltages of the individual load cells between SIG+ and SIG-.
2. Compensate for the differences in height:
– Lift the load bearing implement again using the top hexagon nuts on the countersunk
– Slightly tighten the hexagon nuts.
– Loosen the fixing screws on the brackets.
– Use compensation plates to underlay the bracket of the load cell with the smallest output
– Slightly tighten the fixing screws on the brackets.
– Lower the load bearing implement uniformly again as described above.
– Tighten the fixing screws on the brackets.
3. Check the output voltages of the load cells again. Repeat the sequence if necessary.
4.2.9
Checking the installation
NOTICE
Damage to the load cell and elastomer bearing
The correct installation of the load cell and elastomer bearing must be verified, for example,
by checking the installation dimensions. Incorrect assembly can result in damage to the load
cell and elastomer bearing.
● Check the installation of the load cell:
The load bearing implement must be able to oscillate freely.
4.2.10
Installing the grounding cable
1. Prepare a permanently contacting bolted connection such as M10 on the load bearing
implement and foundation for securing the grounding cable.
2. Screw the grounding cable tight.
