8.3 Disturbances / Internal controls

The control unit continuously monitors motor temperature,
the motor protection switch and the rotation / phase of the
motors. In the case of a disturbance the pump will either be
shut off or prevented from starting. This will result in a corre-
sponding alarm and the lighting of an LED.
8.3.1 Phase / Rotation Monitoring
In the case that L2 and / or L3 fail, the "Phase/Drehfeld" LED
will continuously light and the "Störung" relay will activate.
Since the control of L1 is still active, the failure of L1 will not
be displayed. In the case that L1 fails the installed warning
device will sound as long a battery has been installed in the
control unit. In the case that the rotation is incorrect, the
"Phase / Drehfeld" LED will blink.
In the operational mode "Hand" it is possible to run the pump
with the incorrect rotation – in all other operational modes the
control unit will block the functioning of the motor in the case
that the rotation is incorrect.
