There can be connected 1 or 2 force sensors to each channel. Using 2 force sensors in
1 channel, the connection cables will be wired parallel. The output signal of the measuring
amplifier then will correspond to the average value of the 2 sensors.
The connection between force sensors and measuring amplifier has to be done using
2x2x0.75mm
2
[AWG 18] shielded twisted-pair cable. (With cable length below 15m,
2x2x0.25 mm
2
[AWG 23] is also suitable.) The cable must be installed separate from power
lines.
The terminals 10d and 10z have to be connected to earth.
Caution
Bad earth connection may cause electric shock to persons, malfunction of the total system or
damage of the electronic unit! It is vital to ensure that proper earth connection is done.
