preferred source. If both LEDs are off, neither source is

 

 

preferred. If a source is asynchronous, the source’s LED will

 

 

flash once per second.

 

 

 

Source A and B LEDs

Provides information about the input voltage from each source.

 

 

If the RMS input voltage and the measured frequency are

 

 

within the selected tolerance range, the corresponding

 

 

indicator will light.

 

 

In a normal operating condition (full source redundancy), both

 

 

LEDs are illuminated.

 

 

 

Connector LEDs

Indicates which source is being used for the output (only one

 

 

arrow will be lit at any time). The combination of Source

 

 

LEDs, Connector LEDs, and Output LED provide a graphical
