Fairbanks Portable Axle Load Scale - Manual (Page 11)

A. Load Cell Replacement
1. Remove power to the indicator.
2. Remove the platform access cover, then the junction box cover, and disconnect
the failed load cell cable at the junction box. Loosen the gland bushing and tie a
string or wire to the end of the cable to act as a pull wire. (Check that all cells
have wire markers on the cable ends. If not, identify cells with wire markers or
other means.) Disconnect the faulty load cell’s wires from the terminal block.
3. Lift the platform and use wood blocks for safety.
4. Remove the load cell pulling the load cell cable through the scale while leaving
the pull string/wire in the scale.
5. Install on the new cell.
6. Disconnect the pull string/wire from the old cell's cable and attach to the new
load cell's cable end. Pull the cable of the new cell through to the junction box.
7. Lower the scale onto the new load cell, removing the safety blocks.
8. Connect the load cell wires into the junction box and tighten the box gland
bushing(s).
9. Recalibrate as necessary.
10. Replace the box cover and torque all screws to 10-12 in/lbs. Replace the
platform access covers.
