•
The time when the pump controller operated to the lower limit of PI output frequency after starting is determined by the ACC time.
•
If the delay time counting conditions of various faults, such as weak light, full-water and underload are met, the pump controller counts the
delay time separately. After the delay time of a fault is reached, an alarm is reported and the delay time of the other two faults are still
counted. After the alarm is restored, if the conditions of the other two faults are met, the counting of the delay time is continued. If the
conditions of a fault are not met, the fault delay time is reset to zero.
When P18.15 is set to 1, the total flow of the pump is reset and P18.13 and P18.14
are reset to zero to re-calculate the flow.
After the reset, P18.15 is automatically modified to 0.
It is used to set the reference voltage of the bus when PV input is adopted.
For models of 220V, the default value is 330.0V.
and for models of 380V, the default value is 570.0V.
Setting range: 220.0V–600.0V
When the PV voltage reaches the start voltage, the boost circuit is started.
Setting range: 60.0V–300.0V
The default value depends on power level.
For models of 220V:
0.75kW: 80.0V
1.5kW, 2.2kW and 4kW: 100.0V
For models of 380V:
2.2kW–5.5kW: 220.0V
