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).
3. Lift the platform end and secure using wood blocks for safety.
4. Remove the load cell mounting bolts (use a ¾" socket), then the cell, pulling the
load cell cable through the scale while leaving the pull string/wire in the scale.
5. Remove the foot assembly from the old cell and install on the new cell, using anti-
seize on the threads.
6. Disconnect the pull string/wire from the old cell's cable and attach to the new cell's
cable end. Pull the cable of the new cell through to the junction box, then mount
the cell using anti-seize on the mounting bolts, torque to 90 ft/lbs.
7. Lower the scale to the surface removing the safety blocks.
8. Ensure that the weight is shared equally by all four (4) feet. Connect the load cell
wires into the junction box, tighten the box gland bushing(s) then test and calibrate
the scale. Replace the box cover and torque all screws to 18-20 in/lbs. Replace
the platform access cover.
9. Recalibrate as necessary.
