When 14-37=0.0 (sec), switch off this function.
When pump is at shutdown state, pressure will drop over time if pipeline leaks. Inverter will keep
sleep state if pressure variation is lower than the value of parameter 14-38 in every detection time
(14-37) and pump will restart if pressure variation is larger than that of 14-38 or pressure tolerance
range is over the value of parameter 14-39 in the detection time.
。
Properly adjust the relevant leakage detection parameters 14-37, 14-38 and 14-39 to improve the
condition of frequently pump start and stop caused from the dropping pressure of water system due
to leakage.
Function of leakage detection is enabled only in the setting of single pump.
14-71 Maximum Pressure Setting
Range 【0.1~650.0】PSI
14-72 Switching Time of Alternation in Parallel
Range
0: Hour
1: Minute
When 23-72=0, parameter 23-29 will be in the unit of hour.
When 23-72=1, parameter 23-29 will be in the unit of minute.
