Once the dip switches on the unit are set, tick the checkbox on the form, and click Save
configuration. Check the 115S Detected panel to ensure that the analog mode has been
updated (to Current, differential).
Clicking Read from 115S will read the scales out of the unit (if any) and display them in
the scales grid. Note that the dip switches should be set correctly for this result to be
relevant.
Choose the desired scale for each channel in the Scale box. Click the Save scales to 115S
button, and check that the scales are updated in the 115S Detected panel.
4.5 115S-13 configuration
4.5.1 Voltage output
Voltage outputs may be selected in the scales 0 to 5V, 0 to 10V, or 1 to 5V. For each
scale, the minimum to maximum signal levels are represented by 4000 hex to C000 hex.
Table 4-3 shows how signals from other ELPRO products translate to 115S-13 voltage
levels.
