4-wire connection
Connect 3 and 4, and 5 and 6 as shown below.
Even 4 and 6 on the terminal block are open, normal operation is performed apparently, but heating
or breakage may occur because excessive voltage is applied to the load cell.
For connection, use the accessory jumper lines.
CAUTION
- The load cell excitation voltage of the F701-P is 5V. Heating or breakage may occur
unless the load cells maximum excitation voltage is 5V or more.
- When using the F701-P with the four-wire load cell connected, be sure to connect
+EXC and +S, and -EXC and -S. Even if +S and -S are not connected, normal
operation is performed apparently, but heating or breakage may occur because
excessive voltage is applied to the load cell.
