Operation of the pump in the case of external flow

The pump can start and be operated in the case of positive external flow (generator
operation) with up to 100 % of its maximum flow rate (e.g. pumps connected in
series)
The pump can start and be operated in the case of negative external flow (turbine op-
eration) with up to 20 % of its maximum flow rate.
NOTICE
The pump may still be live even in voltage-free state. The driven rotor induces a
voltage within the pump. This results in undefined flashing of the LEDs. This be-
haviour stops as soon as the external flow stops or when the pump is connected
to the power supply.

The settings can no longer be changed.
The LED of the selected control mode (Fig. I, Item 9) flashes constantly every
second.
The settings can be made again.
Press and hold the operating button for 2 seconds and switch off the pump.
Let go of the operating button.
Switch on the pump again.
