PV500 series solar pumping inverters
Function
code
Note:
The time when the pump inverter operated to the lower limit of PI output frequency after

inverter start-up is determined by the ACC time.
Delay time counting follows the rules if multiple fault conditions are met simutaneously: For

example, if all fault conditions of weak light, full water, and underload are met at the same
time, the inverter will count the delay time for each fault independently. If the delay time of a
fault is reached, the fault is reported. The delay time counting of the other two faults keeps.
If the reported fault is resolved but the conditions of the other two faults persist, the delay
time counting of the other two faults continues. If a fault condition is not met during counting,
the delay time of this fault is cleared.
