GENERAL INFORMATION
Generator
The Multiquip DCA6SPX4F is a 6.0 kW (continuous output),
7.0 kW (max. output) AC generator designed as a portable,
dual-purpose power source for 60 Hz (single phase),
120/240V for lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.
Control Panel
The control panel is provided with the following:
Single Phase 3-Wire Output Terminal
AC Voltmeter
Circuit Breaker @25 Amps
Starter Switch
Warning Lamp Unit
Hour Meter
Ground Terminal
Voltage Regulator
Engine Protection System
Engine protection fail-safe features are provided in the event
of low oil pressure, high coolant temperature, or failure of
the battery to charge. If any of the above conditions occur
while operating the generator it will cause a complete unit
shutdown.
Battery Charge Alarm
This unit is equipped with a protective shutdown device
that signals the emergency relay and automatically stops
the engine when loss of charge from the engine alternator
occurs. An indicator lamp will be displayed on the control
panel.
Water Temperature Alarm
This unit is equipped with a temperature switch that signals
the emergency relay and automatically stops the engine
when the temperature of the engine coolant becomes
abnormally high.The coolant temperature switch will not
function properly if the machine is operated with less than
the proper amount of coolant.
Oil Pressure Warning Alarm
This unit is equipped with an oil pressure switch that detects
low oil pressure. If the lubricating oil pressure of this unit
should become abnormally low, the oil pressure switch
signals the emergency relay to shut down the engine. If
this condition should occur, please refer to the engine
troubleshooting table in this manual.
Excitation System
The DCA6SPX4F generator uses a brushless exciter to
create rated-output electricity. This system will use the
mechanical energy generated by the 1,800 rpm engine
to spin the rotor (or armature) inside the generator (or
alternator end).
Excitation current is sourced from the battery to the
excitation winding in the stator. Current applied to this coil
creates a magnetic field. The rotating armature within the
stator is then induced with AC current.
Engine
The DCA6SPX4F generator is powered by a water-cooled,
4-cycle, Kubota D1105 diesel engine. This engine is
designed to meet every performance requirement of the
generator. Reference Table 2, engine specifications.
In keeping with Multiquip’s policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.
Power Tools (Grounding)
When using power tools or electrical equipment requiring
AC power from the generator, make sure power tool cord
has a ground pin or is double insulated as shown in Figure 4.
Figure 4. Ground Pin
NOTICE
Double-insulated power tools and small appliances
have specially insulated housings that eliminate the
need for a ground. These types of double-insulated
power cords are designed so that no part of the device
will be electrically live even if the internal insulation fails.
