Engine start connection for other transfer switches or a remote start/stop switch
Note:
®
Do not use the Kohler Model RRT transfer switch with Model RCL generator sets.
Other Kohler transfer switches, including Model RDT or Model K (MPAC
generator sets covered in this document. These transfer switches contain separate ATS controls that do not communicate with
the RDC2 controller.
These transfer switches use a set of contacts to signal the engine/generator to start. When the normal source fails and the
generator set is in AUTO mode, the transfer switch contacts close to signal the generator set to start and run. After the normal
source returns, the contacts open to signal the generator set to stop.
The engine start terminals are usually located near the transfer switch contactor with an engine start decal identifying the
terminals. Use the transfer switch wiring diagrams to identify the engine start terminals prior to making connections.
Connect the transfer switch engine-start contacts or a remote manual engine-start switch to the engine start terminals (3 and 4)
on the generator set. Size the wire according to the transfer switch connection and the length of run. Use separate conduit for
the DC engine-start leads and the AC generator set load cables and battery charger leads. See Figure 14.
Close the remote start contacts to start and run the generator set. Open the contacts to signal the generator set to stop. The
generator set controller must be in AUTO mode for remote start/stop.
