1, the target pressure:
Setting range: 0-sensor maximum value target value required by the system Unit: mpa
2. Wake up Garcan
Setting range: 0-set pressure value
When the system goes to sleep, the difference between the feedback pressure and the target pressure is lower than the parameter value, and the system exits the sleep state after waiting for the sleep wake-up delay.
3, auxiliary pump lower limit
Setting range: 0-sensor maximum value
When the system goes to sleep, the auxiliary pump starts the lower pressure limit. 4, pump time
Setting range: 1-999 s
When the variable pump frequency reaches 50Hz and the feedback pressure (PV) is lower than (target pressure-pump pressure return difference), the time set by this parameter is maintained, and the pump action is added.
5, reduce pump time
Setting range: 1 -999 s
When the frequency of the variable displacement pump drops to the lower limit frequency of the main pump and the feedback pressure (PV) is still higher than (the target pressure is changed to the pressure difference of the pump), the time set by this parameter is maintained, and the pump action is reduced.
6, frequency conversion acceleration
Setting range: 1 - 999 s
Frequency converter from 0-50HZ required time. 7, frequency conversion acceleration
Setting range: 1 -999 s
The time required by the inverter from 50-OHZ. 8 Sleep frequency
Setting range: lower limit frequency of main pump -50Hz
This parameter sets the judgment frequency value for the control system to enter the sleep state.
9 Sleep delay
Setting range: 0-999 s
This parameter sets the judgment delay time for the control system to enter the sleep state.
10 Change pump time
Setting range: 0.0-999 minutes
Set this parameter to use each pump evenly to prevent corrosion of the pump. this time is the actual time difference. when the running time interval is reached, if any pump is in ihuayi e:u-the longest pump stops, the stopped pump will be put into operation.
