It is this system electric control theory figure as shown in Fig. 2-Fig. 3.
System principle is：Conventional water supply pump motor M1 has two kinds of power frequency, frequency conversion methods of operation, by be closed KM0, KM1 come
Realize switching.In addition M2, M3 are sewage pump and fire pump respectively, are closed by KM2, KM3 and realize work.
It is closed air switch QF1, QF2, QF3, it is manual/auto to be placed in auto state.S1 (H/A), frequency converter are pinned at this time
In soft start state, then pin S2 (H1), Y1-CY1 is closed KM0 coils and obtains electric, and main contacts is closed, and is set according to frequency converter
The functional parameter set, water supply pump enter converting operation state.When water pump operation frequency reaches the switching of preset manual soft start
When frequency, Y1-CY1 disconnects KM1 coil losing electricities, and main contacts disconnects.Y2-CY2 is closed KM1 coils and obtains electric, and water supply pump enters work
Frequency operating status, Soft Start-up Process terminate.
S1 start buttons are pressed, frequency converter enters operating status.UP, DWN are pressed respectively realizes that frequency increments, successively decrease tune
Whole, motor is run under the frequency of setting, and display frequency is adjusted value.S0 buttons are pressed, frequency converter is out of service.
PWH buttons are pressed, the relay output Y6 of frequency converter starts, sewage pump operation.PWL buttons are pressed, frequency converter
Relay exports Y6 and disconnects, and sewage pump stops.
FIR buttons are pressed, fire-fighting signal is simulated, frequency converter relay exports Y5 and starts, fire-fighting pump operation.FIR is disconnected to press
Button, fire-fighting alarm signal are cancelled, and fire pump is out of service.
