After a voltage drop the pump automatically starts up again with the
performance last set, or remains stopped if it had been stopped
beforehand.
The pump can be turned on and off using the control cable (potential-free
contact) intended for this purpose. This can be via a BADU Logic control,
BADU OmniTronic or via a small coupling relay. This puts less stress on
the electronics.
Overview of possible operating and error messages
If a defect occurs, the motor switches off permanently. Exception error:
"Undervoltage". The motor automatically switches back on as soon as the
voltage is over 209 V for at least 6 seconds.
If an error occurs, the system must be disconnected from the power
supply. See chapter 2.2 of the original operating manual "non self-priming
and self-priming pumps with/without plastic lanterns (AK version)".

Resetting:
The motor can be reset to the state of delivery by
pressing the button for at least 15 seconds. The
motor stops and the three LEDs of the performance
levels light up.
The display of the control unit switched off after
3 minutes without action, except if an external control
unit for example emits a signal to the pump every
minute.
