Load Cells
To attach cable from a load cell or junction box,
remove connector J1 from the board. The connector
plugs into a header on the board as shown in
Figure 2-6 on page 10.
Wire the load cell cable from the load cell or junction
box to connector J1 as shown in Table 2-1. If using
6-wire load cell cable (with sense wires), remove
jumpers JP1 and JP2 before reinstalling connector J1
(see Figure 2-2). For 4-wire installation, leave
jumpers JP1 and JP2 on.
When connections are complete, reinstall connector
J1 on the board and use two cable ties to secure the
load cell cable to the inside of the enclosure as shown
in Figure 2-2.
