3.3.3 LOAD TRANSFER
The transfer of load when the generator is running is dependent
upon the operating mode as follows:
1. Manual
• Will not transfer to generator if utility is present.
• Will transfer to generator if utility fails (below 65% of nominal for
10 consecutive seconds.
• Will transfer back when utility returns for 15 consecutive sec-
onds. The engine will continue to run until removed from the
Manual mode.
2. Auto
• Will start and run if Utility fails for 10 consecutive seconds.
• Will start a five (5) second engine warm-up timer.
• Will not transfer if utility subsequently returns.
• Will transfer to generator if utility is still not present.
• Will transfer back to utility once utility returns (above 75% of
nominal) for 15 seconds.
• Will transfer back to utility if the generator is shut down for any
reason (such as the switch is in the OFF position or a shutdown
alarm.
• After transfer, will shut down engine after one (1) minute cool-
down time.
3. Exercise
• Will not exercise if generator is already running in either Auto or
Manual mode.
• During exercise, the controller will only transfer if utility fails
during exercise for 10 seconds, and will switch to Auto mode.
3.3.4 UTILITY RESTORED
Initial Condition: Generator supplying power to customer load.
When the utility returns (above 75% of nominal), a 15 second
return to utility timer will start. At the completion of this timer, if
the utility supply is still present and acceptable, the control will
transfer the load back to the utility and run the engine through a
one (1) minute cool down period and then shut down. If utility fails
for three (3) seconds during this cool down period, the control
will transfer load back to the generator and continue to run while
monitoring for utility to return.

MANUAL OPERATION

This transfer switch is suitable for manual transfer under load
providing the dead front cover is in place.
Manual operation must be checked BEFORE the transfer switch
is operated electrically. To check manual operation, proceed as
follows:
1. Turn the generator's AUTO/OFF/MANUAL switch to OFF.
2. Turn OFF both UTILITY (service disconnect breaker) and the
main line circuit breaker on the generator.
3. Note position of the 2 switches below the transfer switch
operator.
• Utility supply switch (left side) ON and Generator supply
switch (right side) OFF – LOAD terminals are connected to
the Utility.
• Utility supply switch (left side) OFF and Generator supply
switch (right side) ON – LOAD terminals are connected to the
Generator.
3.4.1 CLOSE TO UTILITY SOURCE SIDE
Before proceeding, verify the position of the transfer mechanism
by observing the position of 50A, 2-pole switches.
If the Utility Supply switch (left side) is ON, no further action is
required.
If not, move the Utility Supply switch handle to the ON position.
Note: the Generator Supply switch handle should move to the OFF
position.
The customer load is now connected to the Utility supply.
3.4.2 CLOSE TO GENERATOR SOURCE SIDE
Before proceeding, verify the position of the transfer mechanism
by observing the position of 50A, 2-pole switches.
If the Generator Supply switch (right side) is ON, no further action
is required.
If not, move the Generator Supply switch handle to the ON posi-
tion. Note: the Utility Supply switch handle should move to the OFF
position.
The customer load is now connected to the Generator supply.
3.4.3 RETURN TO UTILITY SOURCE SIDE
Move the Utility Supply switch handle to the ON position. Note: the
Generator Supply switch handle should move to the OFF position.
The customer load is now connected to the Utility supply.
