After operating start and stop function refers to device energising, through remote signal control, detecting through liquid level and device self, enter holding state after device time delay 3s, self detection time and delay time are adjustable.
The constant voltage function of motion: water-aspirator pressure reaches water pump time delay 20S during the upper pressure limit set and stops, and enters holding state, and water supply terminal exports, and hydraulic pressure reaches starting mode of pump during the low pressure limit set.Wherein delay time is the most adjustable with pressure set points.
Abnormity of power supply: the rated power supply pressure limit of motor is 18V > DC > 28V, when pressure of powering is beyond this scope, unit protection, and export warning (this warning can only be re-energised reset)
Pressure anomaly: when device pressure is less than set minimum pressure values; device thinks air-breathing; device time delay 5S shuts down; it is again started up after the 60S of interval, when pressure is still unable to reach minimum pressure values for the third time, unit protection; report to the police; delay time and interval time are the most adjustable, and this warning can use remote reset, and available power delivery mode again resets.
Shutting down abnormal: when device continuous operation time exceedes set time value, device is shut down, and is again started up after 30S, and third time still exceedes the setting time; device thinks that outfan leaks, and device is shut down, and reports to the police; interval time is adjustable, and this warning can use remote reset, and available power delivery mode again resets.
Anomaly sensing: pressure transducer, flow transducer fault, device is shut down, and reports to the police, and this warning can use remote reset, and available power delivery mode again resets.
Motor abnormality: driving and Hall damages, device is shut down, and reports to the police, and this warning can use remote reset, and available power delivery mode again resets.
Controlling abnormal: controller internal hardware or software fault, device is shut down, and reports to the police, and this warning can use remote reset, and available power delivery mode again resets.
CRANK PULSES: when device starts, device sends corresponding signal, and this signal is passive signal.
Report to the police and export: after plant failure, device sends corresponding alarm signal, and this signal is passive signal.
Power reset: device institute protected and report to the police after, the mode of power transmission can reset the most again.
Remote reset: device non-power ancient costume is protected, and other error protections all can reset by the way of long-range start stop signal puts into again.
