The whole sequence is repeated and start from 1
again until the Auto button on the HMI is released
or signal from I/O or fieldbus is removed.

Water hammering
If water hammering is not a problem parameter 29.08
(Pump clean stop mode) can be set to Dynamic brake
which will ensure a quicker deceleration and therefore
better pump cleaning performance. The Dynamic brake
can be adjusted by the parameter 29.06 (Pump clean
brake strength) and parameter 29.07 (Pump clean brake
timeout).
However if water hammering, which can damage the
pipes, is a problem the parameter 29.08 (Pump clean
stop mode) can be set to Voltage ramp and brake or
Torque ramp and brake. The parameter 02.05 (Stop ramp
end level) and parameter 02.06 (Stop ramp time) are also
used in the Voltage ramp and Torque ramp.
