6.8.3 Changing to Single Side Measurement If One Load Cell Is Faulty
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.
Changing from StandardRoll to SingleSide, see Section 6.8.3.1 Menus for Changing from
Standard Roll to Single Side Measurement.
