2.7 Model RXT Transfer SwitchOperation

The RDC2 generator set/transfer switch controller

manages automatic transfer switch (ATS) functions

whenconnected to a KohlerrModel RXT transfer switch

through the ATS interface board. Refer to the Model

RXT Operation/Installation Manual for information

about the transfer switch operation.

2.7.1 Source Availability

The Model RXT transfer switch supplies voltage

sensing data to the RDC2 controller through the ATS

interface board. If the source voltage falls below the

undervoltage dropoutsetting, thesource is considered

to have failed. SeeFigure 2-7.

Figure 2-7 VoltageSensing Parameters

The RDC2 controller also has a set of power system

LEDsbelow the pushbuttons. Thepower system LEDs

indicate which power sources are available and which

source is supplying power to the building. See

Figure 3-1.

Note: The power system LEDs operate only if a Model

RXT transfer switch is connected. Theywill not

operateif a Model RDT or RSB transfer switch is

used.
