Stop mode
Function description
Two stop modes are available as follows:
● Normal stop: All pumps running in line operation are switched off simultaneously as soon as
the stop command is received. The pump in converter operation stops under the control of
the converter. Normal stop aims to quickly stop all the pumps under emergency situations
such as pipe cracks or leakages.
● Sequence stop: The pumps running in line operation stop one by one in the reverse
sequence in which they are switched on. There is a delay time (p29537) between every
pump stop. The pump in converter operation stops under the control of the converter after
the first pump in line operation is switched off. Sequence stop aims to reduce the water
hammer effect to pipes especially in systems with high power range.
