	Item	Description
	Source A and B LEDs	Provide 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	Indicate 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
		view of the power flow through the ATS.
	Output LED	Shows that voltage is available at the output for the ATS.
	Preference key	Sets the preferred source to supply power to the load
		equipment. In normal operation, if both sources are available,
		the ATS will use the preferred source. Press the Preference key
		to change the preferred source. Press and hold for ten seconds
		to restart the ATS. The restart occurs without resetting
		communications and is confirmed when both status LEDs flash
		off, then on.
	Preference A and B	Indicate which of the two sources is selected as the preferred
	LEDs	source. If both LEDs are off, neither source is selected. If the
		sources are asynchronous, the LED for the selected source will
		flash once per second.
	Reset switch	Restarts ATS network and serial communication.
	Digital display	Digital display of the current used by the ATS and attached
		devices:
		• Shows the aggregate current for the bank/phase
		corresponding to the Bank/Phase Indicator LED that is
		illuminated.
		• Cycles through the banks/phases in 3-second intervals.
	Control key	• Press to change the bank/phase of the current displayed on the
		digital display.
		• Press and hold for five seconds to display the IP address of the
		ATS.
