Load Transfer
With the generator running, the transfer of load is dependent upon the operating mode as follows:
AUTO
• Starts and runs if utility power fails (falls below 60% of nominal) for five consecutive
seconds (adjustable).
• Starts a five second (adjustable) engine warm-up timer.
• Does not execute transfer if utility power returns before expiration of warm-up timer (but
finishes the warm-up and cool-down cycles).
• Transfers back to utility once utility power returns (above 80% of nominal) for fifteen 
consecutive seconds.
• Only shuts down if OFF is pressed or an alarm shutdown occurs.
• Once utility power returns, starts a cool-down cycle before it shuts down.
NOTE: Cool-
down cycle is five minutes if turbocharger equipped, one minute if naturally 
aspirated.
EXERCISE
• Only works in AUTO mode.
• Does not exercise if generator is already running in AUTO.
• During exercise cycle, transfers only if utility power fails for ten consecutive seconds.
MANUAL
• Engine cranks and runs even if utility power is present, but does not transfer to generator.
• Transfers to generator if utility fails (falls below 60% of nominal) for ten consecutive
seconds.
• Transfers back to utility when utility returns for fifteen consecutive seconds. The engine
continues to run until the AUTO or OFF key is pressed.

DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result in
death or serious injury, and equipment damage.
Prior to automatic operation, manually exercise the
transfer switch to verify that there is no binding or
interference with proper operation of the mechanism.
Manual operation of the transfer switch is required if
automatic operation fails.
IMPORTANT NOTE: Always use the applicable
t
ransfer switch owner's manual for actual manual
transfer switch operation instructions. The
information presented here describes a transfer
switch, which is not used for three phase
applications. See specific manual for three phase
transfer switch.
