LOAD CELL CONNECTION
The load cell cable must not be routed with other cables, but must follow its own path.
Any 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.
Up to a maximum of 8 350 ohm load cells in parallel can be connected to the instrument. The supply
voltage of the load cells is 5 Vdc and is protected by a temporary short circuit.
The measuring range of the instrument involves the use of load cells with sensitivity up to 3.9 mV/V.
The load cell cable must be connected to terminals 3 to 9. In the case of a 4-wire cell cable, jumper
the terminals 5 to 8 and 6 to 7.
Connect the load cell cable shield to terminal 9.
In case of use of two or more load cells, use appropriate junction boxes (CEM4/C or CSG4/C) of
which the connection is shown below.
