Chapter 11 Maintenance
7. Set your current source to the value that you want to use for the lower reference point and
wait 3-5 seconds until the value displayed by the DeviceConfig has stabilised. Ensure that the
required value is entered for the lower reference point before you press the button to adopt
the lower reference point for the relevant universal input. You can also use the "Set all lower"
button to set the lower reference points for both of the universal inputs at the same time. How-
ever, each of the universal inputs requires its own current source for this purpose. The current
sources must all be set to the same value during this process.
Note: The values for both of the reference points can be selected freely. However, it is
recommended to use a value in the range of 5 mA for the lower reference point and a
value in the range of 20 mA for the upper reference point.
