As in the image below, you will see a blinking "μ-wave temperature issue" warning on the microwave VI. This happens when the "wave guide temp" drops below the threshold level.

• • Steps to follow

1. 1.  Check the front panel of the microwave power supply controller in the control room rack. If it is in fault mode, you will see red warning lights on the front panel.
      1. If it is not in fault mode, proceed directly to step d.
   2. Press the, transmit/standby button two times around one-second intervals. It will clear the warning and start the microwave transmission.
      1. If the warning comes back right at the same time, do not proceed; call the target expert.
   3. In a few seconds, you will see the red line (waveguide temp) in the EIO temperature plot rising. At the same time, the EIP frequency may appear (This may is not appearessential). It will take less than 15 seconds to clear the warning sound and the alerts on the VI. Now the system is back again. No need to perform further steps.

      1. If the temperature does not come back, follow the step d.
   4. Change the Set position (rev) value to 1.75 and press enter

      1. If this action is unsuccessful, change the Set position (rev) value to 2 and repeat step e.

      2. If the issue persists, press the transmit/standby button once on the power supply to switch the mode to standby. Then, call the target expert.

Action needed:

1. 1. 1. 1. 1. 1. 1. Reset the power supply fault state 

• • • • • • • • Press the left button to switch to standby mode. Press it again to Transmit. This will reset the fault.  

If not, try following 

• • • • • • • • Press the left button to switch to standby mode. Press the right button two times (The ode will change from Local → Remort→ Local). Press the left button to switch to Transmit

If not, try following
