2.7 Model RXT Transfer Switch
Operation
The RDC2 generator set/transfer switch controller
manages automatic transfer switch (ATS) functions
when connected to a Kohlerr Model RXT transfer switch
through the ATS interface board. Refer to the Model
RXT Operation/Installation Manual for information
about the transfer switch operation.

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 dropout setting, the source is considered
to have failed. See Figure 2-7.

The RDC2 controller also has a set of power system
LEDs below the pushbuttons. The power system LEDs
indicate which power sources are available and which
source is supplying power to the building.
Figure 3-1.
Note: The power system LEDs operate only if a Model
RXT transfer switch is connected. They will not
operate if a Model RDT transfer switch is used.
