Complete the following steps to replace the load cell
summing board.
1. Power the CubiScan 125 off.
2. Use the Phillips screwdriver to remove the four
screws holding the load cell summing board lid in
place and remove the lid. Refer to Figure 48.
3. Disconnect the load cell connection wires using the
small flathead screwdriver. To disconnect the wires,
insert the flathead into the slot corresponding with
the wire that you want to remove and push down.
The wire will be released.
4. Disconnect the load cell cables from the load cell
summing box by unscrewing the grommet and nut
until the cables can be pulled from the box. Make
sure you keep track of which load cell is which.
Mixing them up will complicate future maintenance.

holding the load cell summing board in place.
6. Remove the damaged summing board and discard it.
7. Locate the replacement summing board and screw it
into place using the screws from step 5.

secure them by screwing on the grommet and nut.
9. Reconnect the load cell connection wires. Refer to
Figure 50.
10. Power the CubiScan 125 on.
11. Balance the load cells. For instructions on this
process, see “Balancing the Load Cells” on page 23.
12. When you have finished balancing the load cells,
replace the load cell summing box lid and secure it
using the screws from step 2.
13. Calibrate the CubiScan 125. See “Scale Calibration”
