The control input DI1 is equipped in the factory with a converter bridge and the function
"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 disconnected, the control input of
the partner pump is evaluated.

NOTICE
During regular operation, it is preferable to switch the pump on or off via
the DI input with EXT. OFF rather than 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 di-
gital input DI1 has been configured.
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.
