2.7Model 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.

2.7.1Source 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.

Item	Setting
Accuracy	±5%
Undervoltage Dropout	90% of Pickup
Undervoltage Pickup	90% of Nominal

Figure 2-7Voltage Sensing Parameters

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. See 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 or RSB transfer switch is used.
