4 Calibration labels and sealing
The WE2111 calibration is implemented digitally. The
results are saved power failsafe.
Settings that change the calibration are only possible in
the setup mode "Full" (password protection
recommended). This also changes the status of the
calibration counter and can therefore be subsequently
recognized. In addition, it is possible to restrict the
access to the Full setup mode so that access is only
possible after the button on the rear is pressed (Fig. 4.1).
The button is covered by a panel and can be protected
by a suitable label, lead seal or seal.

6 Connecting load cells
This section describes how to connect one or more load
cells.
You can connect a maximum of 16 SG load cells in a full
bridge circuit with a bridge resistance of 350Ω each.
Transducer excitation is implemented in the basic device
WE2111 with 5VDC (bridge excitation voltage).
We recommend connecting the load cells via a suitable
junction if several load cells are connected, e.g. the HBM
model VKK2-8.
Important
Not all load cells can be connected in parallel. Refer to
the operating manual of the load cells to see if this is
possible.
For EMC reasons, a double shielded cable is
advantageous for connecting the load cell(s), e.g. HBM
model 4-3301.0071 with 3 ∗ 2 ∗ 0.14 m2.
