4-20mA Ch1
This menu allows the adjustment / assignment of the
measurement value and the scaling of the analogue output
by pressing the
”4-20mA Ch1”
button.
Selection of the analogue output measurement value by
activating the appropriate measured value key in this
example,
“Flow"
.
Possible outputs are flow, velocity and temperature.
In case of no use, please select “
Off”.
The analogue output scaling have to possibilities,
automatic scaling (default) and a manual scaling by the
user. Auto scaling is based on the calibration settings,
means 4mA is set to zero and the 20mA value is based on
the max. settings here 900m³/h
A “manual scaling” needs an activation of the “
scale
manual”
button.
In text fields
"4mA"
and
"20mA"
the appropriate scaling
values are entered, here from zero m³h (4mA) to 300 m³/h
(20mA).
With
"Error Val"
it is determined what is the output in case
of an error at the analogue output.
2 mA Sensor error / System error
22 mA Sensor error / System error
4..20 Output according Namur (
3.8mA
– 20.5 mA)

Inputs / changes to be confirmed with
“OK”
button. Return
