How to operate the leak-proof controller of explosion-proof solenoid valve

If the explosion-proof solenoid valve leak-proof controller circuit is normal, and the battery power is normal, then ON/OFF power supply indicator is always on. If the battery power is insufficient, the power supply indicator flashes once a second, and there is an alarm sound. After starting, the valve will actively run to the CLOSE position of the shut-off valve. During the operation, the CLOSE indicator flashes once every second, and the CLOSE indicator lights up long after the orientation. Press the OPEN button to open the valve at the moment, and the valve runs to the open position. During the operation, the open indicator flashes every second. When it is in place, all the indicator lights go out, and the sensor enters the low power consumption detection condition.

After 1S water immersion is detected, the shut-off indicator is shorter every second, and the buzzer is also shorter. At this moment, the explosion-proof solenoid valve is closed at the beginning until the full shut-off position, and the shut-off indicator is always on when it is in place. (If there is a blockage in the process of closing, the detector will try to run to the open direction, then turn off, try three times can not be closed or in the process of turning off again, then the shut-off indicator will always flash and the buzzer will ring. Suggest failure of valve closing, manual treatment is needed.

In the monitoring situation, the power supply indicator, the On-valve indicator and the off-valve indicator are flashed every 10 seconds to indicate the quantity of electricity. Three lights flash to clarify that the amount of electricity is enough, two lights flash to clarify that the battery can be replaced, one light flash to clarify that the battery has low power, and the explosion-proof solenoid valve will be actively closed after 8 hours. When two lights are low, except alarming for 2 minutes, the others do not move. When only one indicator light alarms, the power consumption is very low, and the power indicator light flashes once in 1s.
