External supply to load cells
If the total resistance of the load cells is ≤75
Ω
(e.g., more than 4 load cells with 350
Ω
),
an external load cell supply is required. In this case, the internal supply is replaced by a
potential-free external supply.
The center of the external supply voltage (0 ext. supply) should be connected to ground
to ensure that the voltage reacts symmetrically to 0.
External supply specifications:
6 V DC +5%, -30%; ripple max. 50 mVpp; asymmetry max. ±3%.
The internal supply is not connected.
