Welcome to watch the teaching video series on installation and testing of the NGH GF60i2 engine. In this episode, we will introduce the calibration of the servo transmission device (servo) stroke of the engine throttle, the calibration of the use of photoelectric sensors, and the adjustment of the temperature sensor position.
This series of videos is suitable for NGH GF60i2 Engine, support custom service, welcome to contact us.
Connect one end of the test bench adapter to the test bench and the other end to a 220V power socket. After powering on, when you hear "drip, drip, drip", the indicator light changes from yellow fast flashing to blue slow flashing, indicating that the device has successfully powered on.
Connect the network port end of the data cable to the test bench.
Open the MET Software.
Connect the USB end of the data cable to the computer, and the device emits a "beep" sound.
The software automatically connects successfully (if it is the first time to connect the software, you need to manually select the port com in the software to connect.)
First, power on the steering gear
Click on "Unlock" on the software
The throttle control rocker arm on the engine remains in its initial state, at which point the throttle is in a "fully closed" state. Push the rocker arm to the top, and at this point, the throttle is in a "fully open" state.
Maintain the throttle valve in the "fully closed" state and install the steering gear rocker arm onto the steering gear.
Tighten and connect the steering gear rocker arm.
On the software, slowly drag the throttle.
The steering gear slowly changes with the throttle until the throttle is in a "fully open" state.
On the software, record the PWM value corresponding to this throttle position as 1500us.
Click "throttle lock" to enter the software configuration system settings interface, and change the maximum PWM value to 1500us.
Click "Settings" to display the successful setting and close the system settings interface.
Complete the servo stroke calibration
Stick the reflective sticker to the position where the photoelectric sensor beam is focused on the propeller (usually at the root or middle of the propeller), ensuring that the beam always lands on the reflective sticker when it touches the propeller.
Rotate the blade and complete the application of reflective stickers on the other side of the blade.
Enter the software configuration system settings interface, fill in the number of photoelectric stickers in the number of blades column (reflective stickers are pasted on each blade), and click on settings.
The distance between the focusing lens of the photoelectric sensor and the reflective sticker is 3-5 cm. Rotate the lens, adjust the beam focus to a point, and then fix the lens.
Move the beam of the photoelectric sensor away from the propeller and aim it at the non sensing surface (air).
Open the cover of the sensor debugging, press the SET button once, and the sensor will display SET.
Move the beam of the photoelectric sensor onto the reflective sticker of the propeller.
Press the SET button again to complete the setup.
Photoelectric sensor calibration is completed.
The test bench adopts an infrared detection temperature collection method, aligning the mirror surface of the infrared sensor parallel to the root of the engine cylinder block at a distance of 1-3cm. Pay attention to keeping the mirror clean and avoiding oil stains from blocking it.
Temperature sensor adjustment completed.
All sensors have been calibrated and debugged (other sensors have been calibrated and debugged before shipment, and there is no need to calibrate again).
Thank you for watching the sensor calibration and debugging video!
