4-98
and after the detecting time (14-30), the Master and Slave of multiple pumps in parallel will be
exchange. Every time the multiple pumps start, the exchange will be processed. Please refer to
the diagram of sleep stop alternative selection action。
14-35=3, timer alternately selected and sleep stop alternately selected will be enabled at the same
time.
14-35=4, when master stop running and the slave need to run, no exchange between Master and
Slave.
14-37 Leakage Detection Time
Range 【0.0~100.0】s
14-38 Pressure Variation of Leakage Detection Restart
Range
When 14-20=0, range is 0.00~65.00
When 14-20=1, range is 0~100
14-39 Pressure Tolerance Range of Leakage Detection Restart
Range
When 14-20=0, range is 0.00~650.00
When 14-20=1, range is 0~100
To limit single inverter to use leakage detection.
When 14-37 = 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 14-38 in every detection time (14-37).
