LOAD CELL CONNECTIONS
The cable of the load cell (or load cells) should not be channeled
with other cables, but has to follow its own path.
The instrument can be connected up to maximum 4 load cells of 350
ohm in parallel. The supply voltage of the load cells is 4 Vdc and is
protected by temporary short circuit.
The measuring range of the instrument involves the use of load cells
with a sensitivity of up to 7,6 mV/V.
The cable of the load cells must be connected to terminals 10-16 of
the 7-pin removable terminal board. In the case of 4-wire load cell
cable, jump terminals 11 with 14 and 12 with 13 .
Connect the cell cable shield to the terminal 10.
In the case of the usage of two or more load cells, use special jun-
ction boxes (CEM4/C or CSG4/C).
