In order to manually transfer load from the utility source to the
generator, follow these directions:
1. Turn OFF or disconnect the utility power circuit to the transfer
switch, using the means provided (such as the utility source
main line circuit breaker).
2. Set the transfer handle to its UTILITY (NORMAL) position with
load circuits connected to the utility power supply.
3. Set the stationary emergency generator’s main line circuit
breaker to its OFF (or OPEN) position.
4. Start the generator.
5. Let engine stabilize and warm up.
6. Check all applicable instrument and gauge readings. When
certain that all readings are correct, move the transfer switch
manual handle to its STANDBY (GENERATOR) position, i.e.,
load circuits supplied by the generator.
7. Set the stationary emergency generator’s main line circuit
breaker to its ON (or CLOSED) position.
8. Load circuits are now powered by the stationary emergency
generator.
RETRANSFER AND SHUTDOWN
For additional information, refer to the applicable control panel
manual for this unit, as well as any literature pertaining to the
transfer switch.
To manually transfer the load back to the utility power source and
shut down the generator, follow these directions:
1. Set the stationary emergency generator’s main line circuit
breaker to its OFF (or OPEN) position.
2. Manually move the transfer switch handle to its UTILITY
(NORMAL) position, i.e., load circuits connected to the utility.
3. Turn ON the utility power supply to the transfer switch, using
the means provided (such as the utility power source main
line circuit breaker).
4. Let the generator run at no-load for a few minutes to stabilize
internal temperatures.
5. Shut down the generator.
OPERATING UNIT WITH AUTOMATIC
TRANSFER SWITCH
If the generator has been installed along with an automatic transfer
switch, such as a GTS-type switch, the engine may be started and
stopped automatically or manually.
NOTE:
Refer to the applicable manual for the transfer switch and to
“Transfer Switch Start Signal Connections”. In addition, please
note the dangers under “Engine Start-up and Transfer.”
