CAUTION
Overloading in a single load cell can no longer be detected from the output signal.
6.2 Connections using the four‐wire technique
With connections to amplifiers using the four‐wire technique the cores BU (blue) and GN
(green) should be connected together, as should BK (black) and GR (grey). Please take in
account that this causes deviations to the sensitivity and the temperature coefficient of
sensitivity that this causes.
6.3 Cable extensions
Cable extensions must be screened and of low capacitance. We recommend the use of
HBK cables which satisfy these requirements. With cable extensions it should be ensured
that a proper connection is provided with low contact resistances and good insulation.
When using the six‐wire technique, the effects of resistance changes in the extension
cable are compensated. If you extend the cable with the four-wire technique, the sensitiv­
ity deviation can be rectified by adjustment. Temperature effects though are only com­
pensated with the operation using the six-wire technique.
The load cell connecting cable should be routed so that any condensed water or damp­
ness forming on the cable can drip off. lt must not be led to the load cell. In addition, it
must be ensured that no dampness can penetrate the open end of the cable.
