6.8.3 Changing to Single Side Measurement If One Load Cell Is Faulty

6-8
If one load cell is faulty it is possible to change from Standard Roll to Single Side Measurement.
Depending on which load cell that is faulty, do the following:
For load cell connections, please refer to cable diagrams in Appendix B, C, D, E, F or G for the
load cell type used in the installation.
Load cell A or C is faulty:
Disconnect the faulty load cell from the Tension Electronics.
Connect a shorting wire for the load cell excitation circuit:
• If load cell A is disconnected:
a. Connect a shorting wire between X2:1 and X2:2.
• If load cell C is disconnected:
b. Connect a shorting wire between X2:5 and X2:6.
Load cell B or D is faulty:
Disconnect the faulty load cell from the Tension Electronics.
Connect a shorting wire for the load cell excitation circuit:
• If load cell B is disconnected:
– Connect a shorting wire between X2:3 and X2:4
• If load cell D is disconnected:
– Connect a shorting wire between X2:7 and X2:8
After having changed the load cell connections, one parameter setting in the Tension Electronics
must be changed.
• If load cell A or B is disconnected:
– Change Roll 1 from StandardRoll to SingleSide.
• If load cell C or D is disconnected:
– Change Roll 2 from StandardRoll to SingleSide.
