frequency converter can output alarm signal. This function can be used to determine the
pipeline blocking. P4.10 or P4.11 is set to 22, is the output of lower pressure alarm

P7.27 Remote pressure gauge range Range
：
0.001—20.00Mpa 1.000
This parameter setting is equal to actual use of gauge range, corresponding to 10V or 20mA.
P7.28 Multi pump operation mode Range
：
0 , 1 0
P7.29 Pump shift in timed intervals Range
：
0.5—100.0h 5.0
Multi pump operation mode for each pump capacity the same system
。
0
：
Fixed sequence shift : According to the detected pressure changes at a fixed shifting
sequence plus or minus pump. General pump start from 0
1
：
Timing of the Shift : This way is actually at a certain time after redefine each pump
number, to ensure that each pump can get equal chance and time to run, in order to prevent
the pump break for a long time no using. Timing of operation time by P7.29 parameter
defined.
P7.30
Pump shifting judgment
time
Range
：
0.1 — 1000.0 second 300.0S
This parameter is used to set the judgment of stability time, when increase or deduce the
