(1) | Preference A/B Button | Press to set a preferred source: the first press sets source A, the second press sets source B, and the third press sets no preference. |
(2) | Source A and B LEDs | Indicate preferred source. If no source is preferred, both LEDs are illuminated. You can also see the preferred source on the LCD Display. |
(3) | Input Connector LEDs | Provide information about input voltage from each source. If the RMS input voltage and measured frequency are within the selected tolerance range, the corresponding indicator will be illuminated. In a normal operating condition (full source redundancy) both sets of LEDs are illuminated. |
(4) | Output Connector LEDs | Indicate which source is being used for the output (only one path will be illuminated at any time). Together, the Source Preference LEDs, the Connector LEDs, and the Output LED show the power flow through the ATS. |
(5) | Output LED | Shows that voltage is available at the output for the ATS. |
