Combined mode
The control input DI1 is equipped in the factory with a converter bridge and the func-
tion “EXT. OFF” is active.
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 fails or the twin-head pump connection is discon-
nected, the control input of the partner pump is evaluated.

NOTICE
In regular operation, it is preferable to switch the pump on or off via the DI input
with EXT. OFF instead of via the mains voltage!
NOTICE
The 24 V DC power supply is only available when the analogue input AI1 or AI2 has
been configured to a type of use and a signal type or when the digital input DI1 has
been configured.
12.5 Application and function of the
analogue inputs AI1 and AI2
Analogue inputs can be used for setpoint input or actual value input. The assignment of
the target and actual value specifications depends on the selected control mode.
Analogue input AI1 is used as actual value input (sensor value). Analogue input AI2 is
used as setpoint input.
