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‐

Strokes/min

n
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
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
„Contact" and „Batch" operating modes, f is the stroke rate which is
