Wiring the Smart Summing Box
In order to get a reading from the load cells, you need to tie them all together into a Smart Summing Box. One Smart
Summing Box per bin is required. Refer to
Addendums A
through
C
for more in depth wiring illustrations.
18. 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.
19. Run the cable from each load cell to the Smart Summing Box.
20. 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 the nut. Be sure to have a drip loop
outside the SSB.
21. Plug in the load cells starting in the upper left until all
load cells are plugged in.
22. Pass the communication cable through the gray liquid
tight strain relief on the right side of the enclosure.
23. Using an appropriately sized wire nut, connect the
wires according to the chart in
Figure 8
.
24. Attach the GREEN/YELLOW ground wire to the bin
via one of the screws used to attach the SSB.
25. Run the communication wire to the BinTrac Dual Breeder
Control.
26. Tighten every strain-
relief (“dome nut”) 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.
27. Set the bin to A using the dip switches inside the summing box. (
