- Whenever there is a loss of microwave frequency, you will hear a continuous warning sound from the microwave computer.
- You will see a blinking "Lost EIP signal!!!" warning on the microwave VI as in the image below
- There are three instances where you can hear this warning
- Case 1 : "Lost EIP signal!!!" on the VI. But EIP on the camera shows frequency numbers
Action needed: Stop the VI by pressing "Stop VI". Restart the VI by pressing the "Run" button
- Case 2 : "Lost EIP signal!!!" on the VI. EIP on the camera is not showing frequency numbers. There is no fault warning on the microwave power supply in the control room rack.
Action needed: Slightly change the motor position until you see the EIP signal
- Enter 1 degree in the VI and press the right arrow to move the motor by 1 degree. Keep pressing until you see a signal. If it is not showing anything after 5 presses, change the value to 5 degrees and repeat.
