Auto-retract controller for HML350 V1/V2 landing gear Manual
This auto‐retractable controller use MS5611 high precision pressure gauge as distance detection sensor, microprocessor with to complete the action. Can drive two Servo at the same time, the Angle of Servos can adjust up and down, drive current 3a@5 v output . Can be manually set the height of the landing gear unfold. There are 4 different height too choose, 4 buttons(Button 1, Button 2, Button 3, Button 4) to setting the height , Height 1<Height 2<Height 3<Height 4 . Parameters: 1.Work voltage:2S‐6S（DC 7.4V‐25.2V） 2.The Static current: Less than 10 ma (dynamic current is determined by the Servo working current) 3.Maximum load: 3A@5V 4.Retract height: More than 1.5 meter Height deviation: About 50cm Work model： 1, Connected the controller to power, the red and blue lights flashing at the same time, this is the barometer in collecting the current ground plane reference point 2. About 3 seconds later, the blue led solid, the red light off. It gets into the normal working model，and you can enjoy your flight。 Servo working angle adjustment:： 1, First hold any one of the button (A,B,C,D), and then connect the controller to power. 2, when you see the blue and red led flashing, release the button, it means getting into the servo working angle adjustment model. 3,Choose the corresponding button to adjusting the angle of the servo which you want to revise 4, Please power off after finished adjustment, And then power on again, working angle adjustment setting saved. The landing gear Retract height adjustment： 1, When getting into normal work model, Please choose corresponding height setting button and holding until the Blue and Red led flashing then turn off, it mean height setting successful finished. 2 Disconnect the power, height setting saved now.
