GENERATOR CONTROL AND 
OPERATION

Refer to the appropriate control panel operator’s 
manual for this unit.

OPERATING UNIT WITH MANUAL 
TRANSFER SWITCH

If the generator was installed in conjunction with a 
transfer switch capable of manual operation only, the 
following procedure applies. A manually operated 
transfer switch is one that will not provide automatic 
start-up and does not include an intelligence circuit.

ENGINE START-UP AND TRANSFER

For additional information, refer to the applicable 
control panel manual for this unit, as well as any lit-
erature pertaining to the specific transfer switch.

DANGER

  The Maintenance Disconnect Switch and the 

AUTO/OFF/MANUAL switches (if so equipped) 
must be set properly, or the generator will crank 
and start as soon as the utility power to the 
transfer switch is turned off. Refer to applicable 
control panel and transfer switch manuals for 
more information.

  Do not proceed until certain that utility source 

voltage is available to the transfer switch and 
the transfer switch main contacts are set to 
UTILITY.

  Do not attempt manual operation until all power 

supplies to the transfer switch have been posi-
tively turned off, or extremely dangerous - pos-
sibly lethal - electrical shock will result.

  Transfer switch enclosure doors should be kept 

closed and locked. Only authorized personnel 
should be allowed access to the transfer switch 
interior. Extremely high and dangerous voltages 
are present in the transfer switch.

In order to transfer load from the utility source to the 
generator, follow these directions:

• Turn OFF or disconnect the utility power circuit 

to the transfer switch, using the means provided 
(such as the utility source main line circuit break-
er).

• Set the transfer handle to its UTILITY (NORMAL) 

position with load circuits connected to the utility 
power supply.

•  Set the standby generator’s main line circuit break-

er to its OFF (or OPEN) position.

• Start the generator.

‹

  Do not crank the engine continuously for longer 

than 30 seconds, or the heat may 
damage the starter motor.

•  Let engine stabilize and warm up.
• Check all applicable instrument and gauge read-

ings. When certain that all readings are correct, 
move the transfer switch manual handle to its 
STANDBY (GENERATOR) position, i.e., load cir-
cuits supplied by the generator.

•  Set the standby generator’s main line circuit break-

er to its ON (or CLOSED) position.

• Load circuits are now powered by the standby 

generator.

RETRANSFER AND SHUTDOWN

For additional information, refer to the applicable 
control panel manual for this unit, as well as any lit-
erature pertaining to the specific transfer switch.

To transfer the load back to the utility power source 
and shut down the generator, follow these direc-
tions:

•  Set the standby generator’s main line circuit break-

er to its OFF (or OPEN) position.

• Manually move the transfer switch handle to its 

UTILITY (NORMAL) position, i.e., load circuits 
connected to the utility.

• Turn ON the utility power supply to the transfer 

switch, using the means provided (such as the util-
ity power source main line circuit breaker).

•  Let the generator run at no-load for a few minutes 

to stabilize internal temperatures.

•  Shut down the generator.

OPERATING UNIT WITH AUTOMATIC 
TRANSFER SWITCH

If the generator has been installed with an automatic 
transfer switch, such as an RTS, HTS, or GTS-type 
transfer switch, the engine may be started and 
stopped automatically or manually.

NOTE:

Refer to the applicable manual for your trans-
fer switch and to “Transfer Switch Start Signal 
Connections”. In addition, please note the dangers 
under “Engine Start-up and Transfer.”
