Connection of the load cells
Any cell cable extension connections must be carefully shielded, respecting the color
code and using the cable of the type supplied by the manufacturer. The extension
connections must be made by welding, or through support terminal blocks or through
the junction box supplied separately.
A maximum of up to six 350 ohm cells can be connected in parallel to the instrument. The supply voltage of
the cells is 5 V DC and is protected against temporary short circuit. The measuring range of the instrument
allows the use of load cells with sensitivity from 1 mV / V to 2,5 mV/V. The load cell cable is connected to
the terminals 2 … 7 of the 7 pin removable screw terminal block. In the case of a 4-conductor cell cable,
The cell cable must not be channeled with other cables (e.g. outputs connected to
remote switches or power cables), but must follow its own path.
The cell cable must have a number of conductors not higher than those used (4 or 6).
In the case of 6-conductor cable, of which only 4 are used (power supply and signal),
connect the reference wires to the respective polarity of the power supply wires.
