4-1-1. 6-Wire connection
The load cell input of the F805AT-CK is a 6-wire (remote sense) connection. 6-wire shielded load cell
cable should be used and kept separate from AC or other noise generating wire.
Remote sense lines are used to detect and correct variations in excitation voltage over long cable runs.
4-1-2. 4-Wire connection
Connect the sense lines to the Excitation lines (pin 1 to 2, pin 3 to 4) in a 4-wire system (shown below).
Failure to comply may result in system damage.
