SMART
Summing Box

Wiring the Summing Box

1. Mount the Smart Summing Box (SSB) on the crossbar under the bin near the front using self-tapping screws where it is easily accessible for maintenance.
2. Run the cable from each load cell over to the summing box.
3. Before plugging the cables in, remove the black plastic lock nut from each cable strain relief. Remove the red plug from each predrilled hole. Pass the cable through the box and then tighten the nut.
4. Plug in the load cells starting in the upper left until all load cells are plugged in.



5. Pass the communication cable through the gray liquid tight strain relief on the right side of the enclosure.
6. Using an appropriately sized wire nut, connect the wires according to the chart in Figure 7.



7. Attach the GREEN ground wire to the bin via one of the screws used to attach the SSB.
8. Run the communication wire to the next SSB or to the BinTrac Indicator. NOTE: When wiring more than one SSB to a BinTrac Indicator, start from the furthest SSB and “daisy chain” the remaining SSB’s until you get to the BinTrac Indicator.
9. Tighten every strain-relief (“dome nuts”) on the box. First tighten the nuts to attach the strain reliefs to the box. Then tighten the dome nut until the cable cannot be pulled out of the box.
10. Set the appropriate bin (A, B, C or D) using the dip switches inside the summing box. (Figure 8)
