Engine Protection System
Engine protection fail safe features are provided in the event
of low oil pressure, high coolant temperature and failure of
the battery to charge. If any of the above conditions occur
while operating the generator it will cause a complete unit
shut down.
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

GENERAL INFORMATION

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 shutdown the engine. If
this condition should occur, please refer to the engine
troubleshooting table in this manual.
Idle Control Switch
The DA7000SSA2/SSA2GH generator is provided with
an automatic idle (engine) control capability for noise
suppression and fuel cost reduction. The automatic idle
control feature automatically engages under a no-load
condition when the switch is in the ON position.
With AC loads of more than 100W (such as lighting
equipment, motor-powered tools, submersible water
pumps, etc.), the engine runs at high speed. When a no load
condition is produced, the engine automatically slows down.
Turn the idle control switch to the "ON" (up) position when
AC loads drawing more than 150W are connected. Turn
the idle control switch to the "OFF" (down) position when
AC loads drawing less than 100W or when a magnetic
switch is used.
Excitation System
The DA7000SSA2/SSA2GH generators use a brushless
exciter to create rated output electricity. This system will
use the mechanical energy generated by the 3600 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 DA7000SSA2/SSA2GH generators are powered by a
water-cooled, 4-cycle KUBOTA diesel engine. This engine
is designed to meet every performance requirement of the
generator. Reference Table 2, engine specifications.
