Transfer Switch Manual
Operation
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 transfer
switch owner's manual for actual manual transfer switch
operation instructions. The information presented here
describes a typical V-style transfer switch, which is not
used for three phase applications.
Transfer to Generator Power
When utility power fails, manually transfer to standby
power and start the generator as follows:
1. Press OFF on the control pad. A red LED illumi-
nates to confirm that the system is in the OFF
mode.
2. Move the Main Circuit Breaker switch down to the
OFF (Open) position.
3. Turn off the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
4. See Figure 4-3. Use the manual transfer handle
(A) inside the transfer switch to move the main
contacts to the STANDBY position (loads
connected to the standby power source) (C).
5. Press MANUAL on the control pad. The engine
cranks and starts.
6. Allow the engine to run for two minutes to bring it
up to normal operating temperature.
7. Move the Main Circuit Breaker switch up to the ON
(Closed) position.
AUTO
• Starts and runs if utility power fails (falls below 65% 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.

• 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 65% 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.
