Universal inputs

Overview
There are four universal inputs. They can be used for monitoring the membranes and the oil
bath on the pump, for example.
Display of channel numbers for universal inputs in digital display:
• 5/In 1
• 6/In 2
• 7/In 3
• 8/In 4
The universal inputs are configured using parameters P.26 to P.29. The display is different
depending on the configured function of the relevant input.
Function as analog input
With the setting of the associated parameters to "0-20", "4-20", "20-0" or "20-4", a
normalization of the analog current (in mA) from 0 to 100% takes place. E.g.:
20-4 -> 20 mA = 0% / 4 mA = 100%
This percentage value is displayed as the measured value and monitored for a configurable
limit value (parameters P.30 to P.33).
