American Power Conversion 250 A manual S2-Generator

ATS/Voltage

S2-Generator

One of the following is displayed to describe the condition of the input from Source 2.

OK	Source 2 is acceptable, as defined in the Transfer Points menu (the generator is
	running).
OFF	The generator is not running.
BAD	Source 2 is not acceptable, as defined in the Transfer Points menu, even though the ATS
	is commanding the generator to run.

Press ENTER when the selector arrow rests at the S2-Generatoritem to display the following:

L1-2,L2-3,L3-1The Source 2 line-to-line input voltage.

L1, L2, L3 The Source 2 line-to-neutral input voltage. These readings are only displayed on Wye systems.

Frequency The frequency of the Source 2 input, in hertz (Hz).

Qual Describes the quality of the input from Source 2. One of the following conditions is displayed:

•Source Good: The source is acceptable, as defined in the Transfer Points menu.

•Low Voltage: The input voltage is below the configured Low voltage Transfer Point on one or more of the phases.

•High Voltage: The input voltage exceeds the configured High voltage Transfer Point on one or more of the phases.

•Phase Imbalance: The percent voltage difference between two phases, as defined by the Phase Balance setting in the Transfer Points menu, has been exceeded.

•Freq Range: The frequency is outside the configured Freq range, as defined in the Transfer Points menu.

•Bad Rotation: The phase rotation does not match the configured Phase Sequence, as defined in the Transfer Points menu.

Phase Sequence Lists the phase rotation (e.g., A-B-C) of the Source 2 input.
