Single mode
The control input of the main pump and the control input of the partner pump are re-
spectively occupied with a control cable and configured to EXT. OFF. Each of the two
pumps is individually switched by its own control input. If the main pump malfunc-
tions or if the twin-head pump connection is disconnected, the control input of the
partner pump is assessed.
Alternatively, a cable jumper can also be put on the partner pump instead of a separate
control cable.

Combined mode
The control input of the main pump and the control input of the partner pump are re-
spectively occupied with a control cable and configured to EXT. OFF. The control input
of the main pump switches both twin-head pump partners off. The control input of
the partner pump only switches the partner pump off. If the main pump malfunctions
or if the twin-head pump connection is disconnected, the control input of the partner
pump is assessed.
