2.7 Model RXT Transfer Switch
Operation
The RDC2 generator set/transfer switch controller
manages automatic transfer switch (ATS) functions
whenconnectedtoaKohlerrModelRXTtransferswitch
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 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 2-7 Voltage 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.
