Analog output
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:
Strokes / min
n
Capacity (= current, calculated capacity)
n
Capacity at 20 mA (= capacity, value adjustable at 20 mA)
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 signal for the current, calculated capacity is calculated by the pump
according to the following formula (here for the range 4...20 mA):
I(4...20) = 16 x (f/fmax) x (L/100) + 4
with
l
- Output current in mA
f
- Stroke rate in strokes/min
L
- Stroke length in %
fmax - Maximum stroke rate in strokes/min
'Contact' and 'Batch' operating modes, f is the stroke rate which is
In the
set in the "Stroke rate" continuous display.

Using the "Diaphragm break" programmable function, you can match the
behaviour under fault conditions of the pump to your requirements, pro‐
vided an electrical membrane rupture sensor is connected.
There is a choice, of whether a membrane rupture should lead to an
'Error' or a 'Warning' . If 'Inactive' is set, the pump does not react to a
diaphragm rupture, however the symbol dia indicates that an electrical
membrane rupture sensor is connected.
