Wiring code (6

To achie
v
e the bestpossible measurement results and to optimize
interference immunity, connect to the
w
eighing electronics
w
ith
H
BM cables
using 6
w
ire circuitry.
If the load cells and the
w
eighing electronics use 4
w
ire circuitry, the sense
terminals are unused.
If the load cells use 4
w
ire circuit and the
w
eighing electronic use 6

circuit, the terminal for sense (+) must be bridged
w
ith the terminal for
excitation (+) as
w

excitation (−). See also the Installation Instructions for the corresponding load
cell.
