temperature level, or if the temperature rises above the high limit during the cooldown cycle.

If a transfer switch other than the Model RXT is used, an additional engine cooldown time delay may be programmed on the transfer switch. To allow the smart engine cooldown on the RDC2 controller to operate most efficiently, set the cooldown time on the transfer switch controller to zero or the minimum time allowed. Refer to the instructions provided with the transfer switch for more information.

2.3.6Automatic Operation with Model RXT Transfer Switch

The Model RXT transfer switch connects to the RDC2 controller through the ATS interface board on the transfer switch. Also see the Model RXT Transfer Switch Operation/Installation Manual for more information about transfer switch operation.

The controller must be in AUTO mode for automatic transfer switch operation.

Automatic Start

The RDC2 controller receives utility source voltage sensing data from the Model RXT transfer switch.

1.If the utility source voltage falls below an acceptable level, the controller starts the engine start time delay.

2.If the utility source is not restored before the time delay expires, the generator set starts.

3.After the Normal-to-Emergency time delay, the ATS is signaled to transfer the load to the emergency source.

Automatic Stop with Engine Cooldown

1.When the utility source is restored, the Emergency-to-Normal time delay starts.

2.When the Emergency-to-Normal time delay expires, the load is transferred to the utility.

3.The generator set runs through the engine cooldown cycle and then stops.

2.3.7Automatic Operation with Model RDT or RSB Transfer Switches

If a Kohler Model RDT or RSB transfer switch is used, the engine start contacts from the ATS must be connected to engine start leads 3 and 4 on the generator set.

The controller must be in AUTO mode to respond to remote start/stop signals from an ATS or remote switch. Press the AUTO button to put the controller into automatic mode.

Automatic Start

The engine start contacts on the ATS close to signal the generator set to start, and remain closed while the generator set is running.

Automatic Stop

The engine start contacts on the ATS open to signal the generator set to stop.
