When the generator is set in the
AUTO
mode, the generator will
automically start
in the event of
comercial power falling below a
prescribed level by means of a
contact closure that is generated
automatically by a transfer switch.
NOTE
Starting (Auto Mode)
Before connecting this generator to any
building’s electrical system, a
licensed
electrician
must install an
isolation
(transfer)
switch
. Serious damage to the
building’s electrical system may occur
without this transfer switch.
DANGER - ELECTRICAL SYSTEM HAZARDS
When connecting the generator to a isolation (transfer)
switch,
ALWAYS
have power applied to the generator's
internal battery charger. This will ensure that the engine
will not fail due to a dead battery.
CAUTION - BACKUP GENERATOR USE

Circuit Breakers (ON)
18. Place the
main
,
GFCI
, and
aux
. circuit breakers in the
ON
position (Figure 53).
19. Observe the generator's ammeter
(Figure 54) and verify it reads the
anticipated amount of current with
respect to the load. The ammeter
will only display a current reading if
a load is in use.

20. The generator will run until manually stopped or an
abnormal condition occurs.

Figure 49. Ammeter
(No Load)
14. The ammeter (Figure 49) will
indicate
zero amps
with no load
applied. When a load is applied, the
ammeter will indicate the amount of
current that the load is drawing from
the generator.
Figure 52. Engine
Tachometer Gauge
17. The
tachometer gauge
(Figure 52)
will indicate the speed of the engine
when the generator is operating.
Under normal operating conditions
this speed is approximately 1800
RPM’s.
16. The
coolant temperature gauge
(Figure 51) will indicate the
coolant temperature. Under
normal operating conditions the
coolant temperature should be
between 180~230°F (82~110 °C)
Green Zone
.

Temperature Gauge
15. The engine oil pressure gauge
(Figure 50) will indicate the oil
pressure
of the engine. Under
normal operating conditions the oil
pressure is approximately 35 to 65
psi. (241~448 kPa). When starting
the generator
