Refer to the functional description for the sequence of
functions and operating modes.
The pump works if:
n pin 1 and pin 4 are connected to each other and the cable is con‐
nected.
n no cable is connected.
The pump does not work if:
n pin 1 and pin 4 are open and the cable is connected.
Acknowledge fault with ‘Pause’
Certain errors requiring acknowledgement can also be
acknowledged using ‘Pause’ instead of using the Quick‐
wheel.
The pump performs one or more revolutions 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 number of revolutions can be controlled by a
current signal. The current signal is connected between pin 3 and pin 4.
Pin 1 and pin 4 must also be connected.
The pump works at a pre-set capacity 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 is factory-preset to maximum capacity.
9.2.3 "Level switch" terminal
There is an option for connecting a 2-stage level switch with pre-warning
and limit stop or a suction lance with continuous level measurement.
