Speck pumpen BADU Variostar Fiche Technique page 20

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 an error occurs, the motor switches off permanently and a
message is displayed. Exception: "Under voltage" if there is a
failure or the power supply switches off. In this case the motor
restarts when the power supply is switched on again.
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)".
