6.4 Analogue output
The analogue output can be set using the fields listed below. If required, a scaling or
inversion of the output can be set in V0H5 and V0H6.

Field Parameter Significance
V8H1 Current output min 4 mA
0: off
1: on
Sets behaviour of analogue output. Default = 1.
0: 3.8...20.5 mA continuous output
1: as above, but 4 mA limit in normal operation
The ouput follows the setting in V0H7 if a fault is detected
V0H4 Output damping τ
0...255 s
Influences the time it takes for the analogue output to
react to a sudden change in level (63% of steady-state
value). Default 5 s. Increasing the value damps the effect
of e.g. rapid level changes on the measured value.
V0H5

4 mA value
20 mA value
Lower range-value of analogue output
Upper range-value of analogue output
Entry in % or after a linearisation in technical units
V0H7 Safety alarm (Output on alarm)
0: MIN
1: MAX
2: HOLD
In order to signal an alarm, the measured value assumes
the selected value.
MIN = 3.8 mA; MAX = 22 mA
HOLD = holds last current value
V9Hß Current output Displays current value of analogue output
