5. Equipment
5-1. Three-phase and Single-phase simultaneous Output
This generator is capable of generating three-phase and single-phase three-wire output
simultaneously. (Three-phase output terminal and single-phase three-wire output terminal are
equipped individually.)
Neither switching operation of output nor switching operation of wiring is needed.
< Note >
Refer to section “7-2. Connecting Load Cables” for Load Connections.
If using three-phase output simultaneously with a single-phase three-wire type output, use
in a range where the total current does not exceed the rated current.
5-2. Available Output Monitor
The available generated output for each output power source is displayed digitally. You can
use the display selector switch to change the display in the following order: three-phase,
single-phase three-wire U-W output, and single-phase three-wire U-N output, and single-phase
three-wire W-N output. Output of three-phase is always displayed when the engine is started.
< Note >
Consider the digitally displayed available output as an
approximate estimate. Be sure to thoroughly consider the
displayed value and the used load capacity when using a load
such as a motor with large starting capacity.
The displayed output capacity might not be correct values if
using a four-wire connection (single-phase using the N
terminal) for a three-phase output power source. Connect to a
single-phase/three-line type power source if using a single-
phase power source.
If “- -” is displayed for the available output, it means that usage
has exceeded the rated capacity. Immediately stop the equipment being used and reduce the
load capacity of the equipment.

The bed of this generator is equipped with a spill containment (structure for preventing
leakage of liquid) so that any spilled liquid will not leak to outside of the generator when oil or
fuel is spilled or leak. Before starting operation, check if there is accumulated liquid in the spill
containment. Flush out any liquid that has accumulated.
(Refer to section “8-4. Checking the Spill Containment” for inspection procedures. )
(Refer to section “10. Inspection/Maintenance (9) Flushing Liquid in Spill Containment”
for flushing procedures.)
The generator is equipped with the following in order to prevent liquid from spilling in case you
forget to flush the liquid: The operation panel is equipped with an indicator that illuminates
when its sensor is triggered as the spill containment capacity accumulated enough liquid to
reach to about 4.1gal. ( 15.4 liters ).
If the liquid stored in the spill containment exceeds approximately about 13.7gal. ( 51.7 liters )
during operation, the SPILL CONTAINMENT overflow warning indicator illuminates, and the
engine will be automatically stopped. If this occurs, flush the liquid stored in the spill
containment.
(Refer to section “10. Inspection/Maintenance (9) Flushing Liquid in Spill Containment”.)
< Note >
Water can also accumulate in the spill containment due to rain entering into the generator.
Accordingly, you should periodically flush liquid accumulated within the generator. However, you
should flush water according to the frequency/amount of rainfall.
The types of liquids that can accumulate in the spill containment include oil, fuel, coolant and
battery fluid such that it is not possible to distinguish between rainwater and other liquids. Dispose
of flushed liquids according to the applicable laws and regulations.

This generator is equipped with the following warning indicators: BATTERY (insufficient
charging), OIL PRESS (engine oil pressure), WATER TEMP (coolant temperature), OVER
SPEED (engine overspeed) and SPILL CONTAINMENT (spill containment amount). When the
engine starts, all the lamps will light off. Moving the starter switch from STOP to START causes
the BATTERY and OIL PRESS warning indicator to illuminate, and all of the indicator lights will
go off as the engine starts. An indicator illuminates if a malfunction/fault occurs during
operation and the engine automatically stops depending on the fault type (except for SPILL
CONTAINMENT).
If the generator automatically stops, move the starter switch to STOP and restart the engine.
Check each illuminated warning indicator at the time of automatic stop, and inspect the failed
component.
(1) BATTERY (Insufficient Charging) Warning Indicator (Low Battery Voltage)
The BATTERY warning indicator illuminates and the engine automatically stops when
charging is not possible during operation. If this occurs, contact authorized distributor where
the generator was purchased.
< Note >
This battery charging warning indicator cannot detect battery deterioration or insufficient battery
fluid. (Refer to section “8-6. Checking the Battery”.)
(2) OIL PRESS (engine oil pressure) Warning Indicator (Low Oil Press.)
CAUTION: BURNS
Always be sure to stop the engine and allow the engine to cool when
performing inspection or maintenance of engine oil. Opening the oil level
indicator or oil filler cap during operation will result in hot oil gushing out.
If the engine oil pressure drops below 14 psi (0.98 x 100 kPa) during operation, the OIL
PRESS warning indicator illuminates and the engine will be automatically stopped. If this
occurs, check the engine oil level and add engine oil until it reaches the maximum level.
< Note >
This oil pressure warning indicator cannot detect oil deterioration. Change the engine oil
periodically. (Refer to section “8-1. Checking Engine Oil”.)
(3) WATER TEMP (Coolant Temperature) Warning Indicator (High Water Temp.)
CAUTION: BURNS
Do not open the radiator cap immediately after stopping the engine.
Doing so will result in hot steam gushing out.
Hot steam gushes out from the coolant sub-tank if the generator overheats.
Do not touch the coolant sub-tank.

13
If the coolant temperature rises above 239 °F(115℃) during operation, the WATER TEMP
warning indicator illuminates, and the engine will be automatically stopped. If this occurs, hot
steam will gush out of the coolant sub-tank. Check the coolant sub-tank coolant level after
the generator cools and add coolant to the coolant sub-tank if it is insufficient. (Refer to
section “8-2. Checking Coolant”.) If the coolant is at the specified amount, it is probable that
the fan belt is loose or there is a coolant leak. Wait for the engine to cool down and inspect
for these problems.
< Note >
The coolant temperature cannot be detected if the coolant level is excessively low. Always be sure
to check the coolant level in the radiator coolant sub-tank before starting operation.
(4) OVER SPEED (Engine Overspeed) Warning Indicator
This generator is equipped with a function such that the engine is automatically stopped if an
engine fault occurs causing the engine speed to increase excessively. If the engine speed
rose above 4,140 rpm during operation, the OVER SPEED warning indicator illuminates, and
the engine will be automatically stopped. If this occurs, it is probable that some malfunction
has occurred in the engine. Contact authorized distributor where the generator was
purchased.
(5) SPILL CONTAINMENT (Spill Containment Amount) Checking Indicator
The SPILL CONTAINMENT checking indicator illuminates if the liquid stored in the spill
containment exceeds approximately about 4.1gal. ( 15.4 liters ) during operation. If it
illuminates, immediately stop the engine and flush the liquid stored in the spill containment.
(Refer to section “10. Inspection/Maintenance (9) Flushing Liquid in Spill Containment”.)
< Note >
The engine may not be stopped only if the spill containment checking Indicator illuminates during
operation.
When the spill containment checking indicator illuminates during operation, stop the engine, check
for fuel, oil and coolant leakage, and repair as necessary.

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  1  ”: The three-phase breaker trips first followed by the single-phase breaker.
“Simultaneous (3  1  )”: The three-phase and single-phase breakers trip
simultaneously.
“1  3  ”: The single-phase breaker trips first followed by the three-phase breaker.
(5) 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 W phase (total)
< Note >
If measuring the output current for a single-phase three-wire type, turn the ammeter selector
switch to “L1+U” or “L3+W”. The voltage cannot be accurately measured if set to “L2”.
Voltage Regulator
(1) Voltage Regulator
This dial is for regulating voltage output by the generator. Turn the
dial clockwise to increase the voltage and counterclockwise to
decrease it.
