Refer to the functional description for the hierarchy of func‐
tions and operating modes.
The pump does not work if:
n
the cable is connected and pin 1 and pin 4 are open.
The pump works if:
n
the cable is connected and pin 1 and pin 4 are connected.
n
no cable is connected.
The pump performs one or more strokes if:
n
Pin 2 and pin 4 are connected to each other for at least 20 ms. At the
same time, pin 1 and pin 4 must also be connected to each other.
The pump capacity and/or stroke rate can be controlled by a current
signal. The current signal is connected between pin 3 and pin 4.
In addition, pin 1 and pin 4 must also be connected.
The pump works at a pre-set capacity / stroke rate if:
n
Pin 5 and pin 4 are connected to each other. At the same time, pin 1
and pin 4 must also be connected to each other. The auxiliary
capacity / auxiliary frequency is factory-preset to maximum capacity /
stroke rate.
9.2.2 "Level switch" terminal
There is a connecting option for a 2-stage level switch with pre-warning
and limit stop.
