Whenever an engine is installed indoors the exhaust fumes
must be vented to the outside.The engine should be installed
at least two feet from any outside wall. Using an exhaust
pipe which is too long or too small can cause excessive
back pressure which will cause the engine to heat excessively
and possibly burn the valves.
When connecting the generator
to any buildings electrical
system ALWAYS consult with
a licensed electrician.
NOTE
Mounting
The generator must be mounted on a solid foundation (such
as concrete) and set firmly on the foundation to isolate
vibration of the generator when it is running. The generator
must set at least 6 inches above the floor or grade level (in
accordance to NFPA 110, Chapter 5-4.1). DO NOT remove
the metal skids on the bottom of the generator. They are to
resist damage to the bottom of the generator and to maintain
alignment.

DCA-70USI (50 Hz) — GENERAL INFORMATION
Open Delta Excitation System
DCA-70USI Ultra Silent™ (50 Hz) Series Familiarization
Generator
The DCA-70USI (50 Hz) generator is equipped with the state
of the art "Open-Delta" excitation system. The open delta
system consist of an electrically independent winding wound
among stationary windings of the AC output section.
The MQ Power Model DCA-70USI (50 Hz) is a 48 kW
generator (Figure 5) that is designed as a high quality
portable (requires a trailer for transport) power source for
telecom sites, lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.
There are four connections of the open delta A, B, C and D.
During steady state loads, the power from the voltage regulator
is supplied from the parallel connections of A to B, A to D,
and C to D. These three phases of the voltage input to the
voltage regulator are then rectified and are the excitation
current for the exciter section.
Engine Operating Panel
The “Engine Operating Panel” is provided with the following:
■
■
■
■
■
■
■
■
■
■
Tachometer
WaterTemperature Gauge
Oil Pressure Gauge
Charging Ammeter Gauge
Fuel Level Gauge
Pre-Heat Pushbutton
When a heavy load, such as a motor starting or a short
circuit occurs, the automatic voltage regulator (AVR)
switches the configuration of the open delta to the series
connection of B to C.This has the effect of adding the voltages
of each phase to provide higher excitation to the exciter
section and thus better voltage response during the
application of heavy loads.
Pre-Heat Lamp
Panel Light/Panel Light Switch
Auto ON/OFF Engine Controller (MPEC)
Fuel Leak Detected Alarm Lamp
The connections of the AVR to the AC output windings are
for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation
current, offering maximum motor starting capabilities. The
excitation does not have a "fixed ceiling" and responds
according the demands of the required load.

and voltage requirements are satisfactorily supplied by the
generator for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require 130—
150% more wattage than the rating on the nameplate, as
the wattage is influenced by the efficiency, power factor and
starting system of the equipment.
If 3Ø load (kVA) is not given on
the equipment nameplate,
approximate 3Ø load output
maybedeterminedbymultiplying
voltage by amperage by 1.732.
NOTE
If wattage is not given on the
equipment's

plate,
approximate wattage may be
determined by multiplying
nameplate voltage by the
nameplate amperage.
Motors and motor-driven
equipment draw much greater
current for starting than during
operation.
NOTE
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table 4 below
when connecting loads.
An inadequate size connecting cable which cannot carry the

General Inspection
Service Daily
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel,
oil, and coolant leaks.UseTable 12 as a general maintenance
guideline Engine Side (Refer to the Engine Instruction
Manual)
If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result.This can lead to
a loss of power, excessive carbon buildup in the combustion
chamber and high fuel consumption. Change air cleaner
more frequently if these conditions exists.
Fuel Addition
Air Cleaner
Add diesel fuel (the grade may vary according to season
and locations).
Every 250 hours: Remove air cleaner element and clean the
heavy duty paper element with light spray of compressed
air. Replace the air cleaner as needed.
RemovingWater from the FuelTank
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally inspect the fuel
tank for water contamination and drain the contents if
required.
Air Cleaner with Dust Indicator
This indicator is attached to the air cleaner. When the air
cleaner element is clogged, air intake restriction becomes
greater and the dust indicator signal shows RED meaning
the element needs changing or service. After changing the
air element, press the dust indicator button to reset the
indicator.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the tank full with dies1el fuel.

Air Removal
Flushing Out Radiator and Replacing Coolant
If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel, or
after disassembling the fuel system, bleed the system
according to the following procedure. See the ISUZU Engine
Manual for details.
Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant.Open the
radiator cap while draining. Remove the overflow tank
and drain.
Check hoses for softening and kinks. Check clamps for
signs of leakage.
To restart after running out of fuel, turn the switch to the
“ON” position for 15-30 seconds. Try again, if needed. This
unit is equipped with an automatic air bleeding system.
Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed.DO NOT
clean radiator core with any objects, such as a
screwdriver.
Check Oil Level
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Insufficient oil may cause severe damage
to the engine. Make sure the generator is level.The oil level
must be between the two notches on the dipstick as shown
in Figure 31.
Tighten both cocks and replace the overflow tank.
Replace with coolant as recommended by the engine
manufaturer.
Close radiator cap tightly.
Replacing Oil Filter
WARNING - BURN HAZARDS
Remove the old oil filter.
Apply a film of oil to the gasket on the new oil filter.
Install the new oil filter.
Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.
After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check
for leaks before adding more oil if needed. Clean
excessive oil from engine.
Generator Storage
Cleaning the Fuel Strainer
For longe term storage of the generator the following is
recommended:
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation or
once a month.
Fill the fuel tank completely. Treat with a fuel stabilizer
if necessary.
Completely drain the oil from the crankcase and refill if
necessary with fresh oil.
Replacing Fuel Filter
Clean the entire generator, internal and external.
Cover the generating set and store in a clean, dry place.
Disconnect the battery.
Replace the fuel filter cartridge with new one every 500
hours or so.
Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.
Make sure engine coolant is at proper level.
If generator is mounted on a trailer, jack trailer up and
place on blocks so tires do not touch the ground or block
and completely remove the tires.
Vent any air.

5. Adjust the brake shoes outward until the pressure of the
lining against the wheel drum makes the wheel difficult
to turn.
Hydraulic surge braking requires the installation of an actuator
at the tongue of the trailer. Remember the surge or push of
the trailer toward the tow vehicle automatically synchronizes
the trailer brakes with the tow vehicle brakes. As the trailer
pushes against the tow vehicle the actuator telescopes
together and applies force to the master cylinder, supplying
hydraulic pressure to the trailer brakes.
6. Adjust, rotate the star wheel in the opposite direction
until the wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower the trailer to
the ground.
Periodically check and test the surge “actuator” to make
sure that it is functioning correctly. Never use an undersize
actuator.

Lug NutTorque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 59). DO NOT
torque the wheel lug nuts all the way down.Tighten each
lug nut in 3 separate passes as defined by Table 16.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
