2.3 Connecting the Indicator to a Scale Base (Cont.)
Refer to the color code of the load cell cable and connect the wires to Terminal Strip J4. Tighten all screws
securely. The connections are shown for a 6 wire cable. When a 4 wire cable is used, the Jump 1 and Jump
2 jumpers on the PC board must be positioned as shown in the illustrations below.
For obtaining better performance, it is recommended to keep both JUMP 1 and JUMP 2 jumpers open when a
6-wire load cell is connected to the CW-11.
6-Wire Jumper Connections.
4-Wire Jumper Connections.
