Microwave Operation

1. Initial status 

Microwave VI will look like as in the image below  

• There are two red warnings in the warning section

The microwave power supply is in the "Standby" (Off) mode

2. Turning on the microwave system

• Press the "Press" button on the microwave power supply to start the high-voltage transmission. The mode will be changed to STANDBY → TRANSMIT 

• Press the "Run the recovery sequence" button on the microwave VI.  The "Motor Running" led will turn on. The motor position will be advanced. 
  

• • You will see EIO temperatures are going up. Especially the red graph (Waveguid) will increase at a higher rate. 
    
  • Once the EIO waveguide temperature goes over 35 ^oC, the "EIO low temperature.." warning will be cleared.
  •  Sometimes "Lost EIP signal" warning will be cleared. (this is not essential)
  • Turn on "Warning sound" button 
    
    
    
  • Once the motor stops, The recovery sequence will be completed. 
• Now the system is ready to polarize 

3. Moving to the polarization phase

• Press the "Start Auto control" button to maximize the polarization. No need to change any other parameters.

4. Recover from Errors

You will hear a warning sound when the EIO waveguide temperature goes below 35 ^oC. 

• Check the microwave power supply for errors. If power supply is in the Error state, Press the, transmit/standby button two times around one-second intervals. It will clear the warning and start the microwave transmission.
• The EIO Waveguied temperature should go up. If not, Press the "Run the recovery sequence" button on the microwave VI and follow the recovery sequence
