Pump cleaning
The Pump cleaning function can be used for preventing solids from building up on
pump impellers. The function consists of a programmable sequence of forward and
reverse runs of the pump (see the figure below), effectively shaking off any residue
on the impeller. This is especially useful with booster and wastewater pumps.
The pump cleaning cycle can be activated at start-up, with a user-defined period, with
a selectable digital input or by the Supervision function (for example triggered by the
motor input current).
