They can be used for monitoring the membranes and the oilbath 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 4The universal inputs are configured using parameters P.26 to P.29. The display is differentdepending on the configured function of the relevant input.Function as analog inputWith the setting of the associated parameters to "0-20", "4-20", "20-0" or "20-4", anormalization 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 configurablelimit value (parameters P.30 to P.33). |
