13
Switches
(1) Starter Switch
STOP
The engine is stopped and all power is
cut off when in this position. The key
can be inserted and removed when in
this position.
RUN/PREHEAT
Position for operating the generator. It
is also the position for air heater
preheating
in
order
to
increase
startability in cold condition.
< NOTE >
Do not leave the generator in this position with the engine stopped.
Doing so will cause the battery to drain.
START
Position where the engine is started. If you remove your hand from the key, the switch
automatically returns to RUN.
(2) Breakers
These switches are for transmitting electrical power to the load side. Turn to ON to output
voltage to the output terminals. Transmission of electricity to the load side is cut off when
there is a short circuit or overload on the load side.
< NOTE >
Do not operate these breakers to operate or stop a load.
(3) Breaker Trip Selector Switch
This switch is for selecting the tripping order of the three-phase and single-phase breaker
when there is a short circuit or overload on the load side. If the three-phase or single-phase
breaker is selected for precedence in tripping, the selected breaker will trip first when the
total generator output exceeds the rated capacity.
After that, the other breaker will also trip if the generator output exceeds the rated capacity
again.
Switch Selection
“3
φ
⇒
1
φ
”: The three-phase breaker trips first followed by the single-phase breaker.
“Simultaneous (3
φ
1
φ
)”: The three-phase and single-phase breakers trip
simultaneously.
“1
φ
⇒
3
φ
”: The single-phase breaker trips first followed by the three-phase breaker.
(4) Ammeter Selector Switch
This switch is for selecting the output current indicated by the ammeter. Change the switch
to display the following output terminal current on the ammeter.
Switch Selection
“L1+U”: Three-phase L1 phase + Single-phase three-wire U phase (total)
“L2”: Three-phase L2 phase
“L3+W”: Three-phase L3 phase + Single-phase three-wire (total)
