↓
1.
Remove the connection cable for the load cell from the terminal block for load cells.
2.
Measure the voltage between A-C after short-circuiting A-F and C-G of terminal
block.
Set the load cell tester to DC voltage measurement.
↓
The voltage between
A and C is stable in
the set value of ex-
citation voltage.
→ No → Contact Minebea Intec.

Inform Minebea In-
tec about the cont-
ens of failure and
situation at site in
details.
Following causes can
be considered.
-
The load cell in-
put exceeds the
range of -3.1 mV/
V to 3.1 mV/V.
-
The load cell is
boken, e.g. due
to overloading.
-
The signal wire to
the load cell is
not connected.
