First, the characteristics: 
 n mainly for underground sewage treatment equipment design. 
 n Use the microcontroller chip as the core manufacturing controller, small size, intuitive display, powerful, easy to operate. 
 In the field without specialized knowledge of the software can directly modify the parameters to adapt to different work-site requirements. Make the whole control 
 System to simplify the circuit, at least, and reliable components. 
 n according to high, medium and low level sensor signal intelligent control fan (one with a prepared), pumps (one with a prepared) and the solenoid valve operation; 
 n rust with automatic pump function; 
 n fan, pump turns working time adjustable; 
 n memory to save up to 10 years; 
 Second, the function: 
 1. Automatic functions: 
 n According to the low water level auto stop, or to determine the open, opening two pumps, a wind machine which is also linked with the water pump running; the water level down 
 Low water level shut down the pumps, fans stopped. 
 n in turn starts the pump will continuously work on a regular switching function; pump will start the rotation, continuous work on a regular switching function; run 
 Pumps in the thermal overload relay, the controller receives a signal to immediately stop the pump running and also the police, start back 
 Pump running. 
 n opportunity to turn the wind started, continuous work on a regular switching function; if the monitoring of the fan for some time (depending on process requirements, when 
 Room can be set) is not running before, then the gap can be automatically run the fan; the operation of the fan to heat overload relay, the controller 
 Received signal will immediately stop the fan running and the same time the alarm to start the standby fan is running. 
 n need a separate set of time control solenoid valve. 
 n has the time to start the pump turns rust-proof function, regular time and work time can be set independently. 
 (2) Manual function: pumps, fans and solenoid valve can separate up and running.
