■Load cell parallel connection
With industrial weighing devices, hopper scale and truck scale configuration is possible for parallel
connection of multiple load cells. The connection procedure is outlined in the diagram below.
Simple parallel connection is possible using an optional B410 (junction box for four-point multi load
cells).
■Sensor cable
Cable colors of sensors differ from one manufacturer to another. (They may also differ from one model
to another for some products.)
Refer to the sensor manual (or data sheet) and check signal names and colors in order to connect the
cables correctly.
Caution
- The F701+ excitation voltage is 10V. Heat and/or breakdown may result if the
maximum excitation voltage of a load cell is not 10V or more.
- Be sure to connect +EXC and +S with -EXC and -S in case a four-line type load cell is
used with the F701+. Normal operation appears possible if -S and +S are not
connected; however, high voltage is placed on the load cell, which may cause heat
and/or breakd
own.

For the group of n pieces of parallel
load cells seen on this device, the
rated capacity is n times and the
sensitivity can be considered as a
load cell of unchanging units.

Attention
When performing parallel
connection, select a load
cell with an adequate
capacity in order to prevent
individual load cells from
overloading due to offset
load, shock and so forth.
