7.2 Replacing a load cell
CAUTION
Re-install the shipping stops during maintenance or any other time when protection of the
load cells is required.
1. Install both shipping stops
2. Support the belt and weighing idler from above or below.
3. Remove load cell hardware from the dynamic (moving) parts.
4. Remove load cell hardware from the static support.
5. Remove the existing load cell from the belt scale.
6. Replace with a new load cell fastening to static support then dynamic (moving structure).
7. Remove belt and idler support.
8. Release both shipping stops
9. Adjust idler alignment if necessary.
10. Perform balance, zero, and span calibrations.
Note
The load cell stop is set at the factory to allow the load cell to deflect up to 150% of its design
load (30 mV at 10 V DC excitation). The overload gap for a replacement load cell should be set
by mV readings.
7.3 Spare parts
The only spare part recommended for the belt scale is the load cell. Refer to the load cell
nameplate for the proper size and model number. Re-balance any load cell that has been
replaced.
