4.3 Fault Indicators and Tips

4.3.1 Gas path blockage

If the device is running automatically or the position of the propulsion device is adjusted manually, if a stall occurs, the motor will stop rotating immediately and stop after running in the opposite direction for about 1mm. At the same time, the interface shown above will be entered. Press the "Confirm" button in the white square area in the middle of the screen to enter the standby display interface. The buzzer will sound once and the indicator light will flash yellow once.

 

4.3.2 Power-off prompt

If an abnormal power outage occurs during the operation of the device or the shutdown button is pressed, the device will resume power supply within 3 minutes. At this time, the interface shown in the figure above will be entered to remind the operator that an abnormal power outage occurred during the last injection. Press the "Confirm" button in the white square area in the middle of the screen to enter the standby display interface. When an abnormal power outage occurs, the device immediately uses the power stored in the backup capacitor to open the solenoid valve and release the negative pressure of the negative pressure system, so that the injection needle can be separated from the skin normally. After an abnormal power outage occurs, the buzzer sounds once per second and the warning light flashes red once for 3 minutes;

 

4.3.3 Motor stall

If the device stalls during automatic operation or when the propulsion device is manually adjusted, the motor will stop rotating immediately and stop after running in the opposite direction for about 1mm. At the same time, the interface shown above will be entered. Press the "Confirm" button in the white square area in the middle of the screen to enter the standby display interface. The buzzer will sound once and the indicator light will flash yellow once.
