Load Cell Wiring Diagrams
The diagrams below show how Hardy Load Sensor with C2 wiring differs from
standard Load Cell (4 wire and 6 wire are similar except 6 wire adds sense wiring. C2
wiring is required when using a Integrated Technician summing junction box. The C2
wires are used for communicating IT and C2 commands.
The simple wiring diagram above shows how to connect a single load cell to the HI
6500 series instrument. Note: when connecting the HI 6500 series instrument to a
junction box, the sense lines would be connected between the +Sen and –Sen
Connections for the junction box and the instrument.
