AEG THYRO-P LBA Logic control module
The cabling, especially the cable to the load cell, is the part that is most exposed to damage. Since the resistance of the load cell windings is low, it is easy to check the load cells and cabling from the control unit. Typical readings are 1 Ω for the resistance of the primary winding and 1-3 Ω for the output impedance of the secondary winding.
Insulation faults in the cabling
or the load cell may cause incorrect sensitivity or unstable zero point. When the load cell circuits have been isolated from earth and from the control unit at the disconnectable terminals, it is easy to measure the insulation from the control unit. If the cables are not routed correctly, they may pick up interference from other cables.For circuit diagram applications, see the manual for the applicable control unit: Millmate Strip Tension Systems with Millmate Controller 400, 3BSE023139Rxxxx
