Notes:
- To limit single inverter to use leakage detection.
- When 23-37 = 0.0 (sec), switch off this function.
- When pump is at shutdown state, pressure will drop over time if pipeline leaks. Pump will restart if
pressure variation is larger than the value of parameter 23-38 in every detection time (23-37).

Notes:
- When 23-37 = 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 23-38 in every detection time (23-37) and
pump will restart if pressure variation is larger than that of 23-38 or pressure tolerance range is over the
value of parameter 23-39 in the detection time.
- Properly adjust the relevant leakage detection parameters 23-37, 23-38 and 23-39 to improve the
condition of frequenct 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.

Local/ Remote Key
Range
【0】∶ Disable
【1】∶ Enable
User can switch reference frequency of the inverter and give the run command in the local or remote
mode.
Input source selection is determined by the source of frequency command (00-05) and the operation
modes (00-02).
