Terminal 24V of the system is connected to power cable positive
of the analog load cell, and terminal M of CN9 on the MCB is
connected to power cable negative of the analog load cell. Terminal
Ai of CN9 on the MCB is connected to the signal cable of the
analog load cell.

â– Load cell auto-tuning
When the analog load cell is used, load cell auto-tuning must be performed; otherwise, the analog
load cell cannot be used. Perform analog load cell auto-tuning to obtain the car full-load/overload
data according to the following owchart.

Make the car unloaded
Set F8-00 to 0.
Press ENTER on the operation panel.
Put N% load in the car
Set F8-00 to N.
Press ENTER on the operation panel.
