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V
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.
