Using the "Analog output" programmable function, you can match the
pump current output signal (optional) to your requirements.
The signal I of the current output signal one of the three following varia‐
bles:
n
Strokes/min
n
Capacity
n
Capacity at 20 mA
In the "Stop" or "Pause" states (either because of a fault or operation) or
"Pause" the current output transmits a current of 4 mA or 0 mA.
The pump calculates the signal for „Strokes / min“ according to the fol‐
lowing formula (here for the range 4...20 mA):
I(4...20) = 16 x (f/fmax) + 4
with
l
- Output current in mA
f - Stroke rate in strokes/min
fmax - Maximum stroke rate in strokes/min
In the
„Contact“
and
„Batch“
operating modes, f is the stroke rate which is
set in the "Stroke rate" continuous display.
The pump calculates the signal for
„Capacity“
according to the following
formula (here for the range 4...20 mA):
I(4...20) = 16 x (f/f
max
) x (H/100) + 4
with
l
- Output current in mA
f - Stroke rate in strokes/min
H - Stroke length in %
f
max
- Maximum stroke rate in strokes/min
In the
„Contact“
and
„Batch“
operating modes, f is the stroke rate which is
set in the "Stroke rate" continuous display.
This menu item is only available with a calibrated pump.
The pump calculates the signal for
„Capacity at 20 mA“
