Two stop modes are available as follows:
● Normal stop: All pumps running in line system operation are switched off at the same time
as soon as the stop command is received. The pump in inverter operation stops under
the control of the inverter.
● Sequence stop: The pumps running in line system operation stop one by one in the
reverse sequence in which they are switched on. There is a delay time between every
pump stop. The pump in inverter operation stops under the control of the inverter after the
other pumps are switched off.
After the OFF command is received, the pumps are switched off in either of the two stop
modes:
● With OFF1 command received, the pump stop mode is selected in P2370 as follows:
– P2370 = 0: normal stop
– P2370 = 1: sequence stop
● With OFF2/OFF3 command received, the pumps are switched off with normal stop.
