The system configuration example in this Guide is based on the assumption that one load cell is in
use, but multiple load cells can be connected in parallel by using a summing box as in the diagram

Precautions for Correct Use
When you use the Load Cell Input Unit with a 4-wire connection, always connect S+
terminal with EXC+ terminal, and S- terminal with EXC- terminal on the terminal block. If
they are not connected, the Load Cell Input Unit does not operate normally.
