Stable pressure water-supplying dormancy system selections: It sets whether use dormancy system while PID for
stable pressure woter-supplying. While use, inverter start dormancy detection if PID feedback higher or equal to PID
setting for a certain time. In dormancy detection process, if feedback is bigger than detection value, inverter reduces
output frequency to [Fb.22] for a while. If PID feedback is still higher than detection value, inverter reduces output
frequency to 0.00Hz, enter to dormancy state. In this process, if feedback is lower than detection value, dormancy
detection is invalid. Inverter is back to PID adjustment state.
0: Invalid
1: Valid
Start-up value: While inverter enters dormancy system, PID feedback must be lower then start-up value. Otherwise
inverter can not start. If start-up value is too high, it maybe causes inverter frequency start and stop. But if it is too low, it
maybe causes under-pressure. It is defined as ratio of PID feedback to sensor max measuring range.
Dormancy detection value coefficient: In process that inverter enters dormancy system in mode of reducing output
frequency, once PID feedback is lower dormancy detection value, inverter back to PID adjustment state. If it set as
1.000, system takes PID setting as exit value in frequency reduce state.Dormancy detection value is defined as the
result of this value multiples PID given.
Dormancy detection DEC time: Set DEC time for invereter reducing frequency in dormancy detection process.
Dormancy detection low point hold frequency: Set frequency that inverter holds at the low point in dormancy
detection process.
