0:Invalid. It is not installed or does not work in the system.
1: Variable frequency pump. It starts with variable frequency.
•
If it is unqualified to switch, it works as an inverter drive adjustable pump for the whole system. It is
controlled by HD31, which adjust the rotating speed of pump according to the actual pressure so as to
maintain constant system pressure.
•
If it is qualified to switch, the pump switches to power frequency running or exit running, depending
on the switch mode.
2: Power frequency pump. It only runs with power frequency.
•
Adopt full-pressure direct start method when the power grid is sufficient and the pump power is
under 15kW.
•
It is recommended to adopt reduced-voltage method such as reduced-voltage of Y-
△
mode, self
coupling voltage start, soft start, etc. for pumps with power of no less than 18.5kW. That can reduce
the impact on the power grid and pipe network.
3: Dormant pump. It serves as dormant pump for the system.
•
The system enters dormant run when it meets the dormant condition. It will enter dormant running or
awaken dormancy according to the dormant pressure and tolerant limit.
4: Sewage pump. It serves as dormant pump for the system.
•
Condition for setting a sewage pump: water level sensor of sewage pool must be installed in the
system and correctly connect to HD31. HD31 automatically controls the start and stop of the sewage
pump according to WL of sewage water pool.
Note:
1. For a pump which is set as variable frequency pump, the corresponding inverter / normal drive relay must be
set again, otherwise it's not recognized as effective pump. After starting the system, HD31 will not output if there
is only one variable frequency pump in the system and no setting for inverter / normal drive relay.
2. For a pump which is set as variable frequency pump, dormant pump and sewage pump, the corresponding
inverter drive relay must be set again, otherwise the is not recognized as effective pump.
