sufficient load (less than 40% of the rated output) it will
not operate at its optimum temperature. This will allow
unburned fuel to accumulate in the exhaust system, which
can foul the fuel injectors, engine valves and exhaust
system, including turbocharges, and reduce the operating
performance.
In order for a diesel engine to operate at peak efficiency it
must be able to provide fuel and air in the proper ratio and
at a high enough engine temperature for the engine to
completely burn all of the fuel.
Wet stacking does usually cause any permanent damage
and can be alleviated if additional load is applied to relieve
the condition. It can reduce the system performance and
increase maintenance. Applying an increasing load over a
period of time until the excess fuel is burned off and the
system capacity is reached usually can repair the condition.
This can take several hours to burn off the accumulated
unburned fuel.

To prevent burns, DO NOT touch or open any of the below
mentioned components while the engine is
running or immediately after operations.
Always allow sufficient time for the engine

If your generator is trailer mounted, please
read the towing and safety requirements
listed below.

Towing and Transporting Safety

To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
that supports the generator and the towing vehicle are in
good operating condition and both units are mechanically
sound.

The following list of safety precautions should be followed
when towing your generator:

CAUTION - FOLLOW TOWING REGULATIONS

Check with your local county or state safety towing
regulations, in addition to meeting

■

ALWAYS shutdown engine before transporting.

■

Drain fuel from generator fuel tank before towing.

■

If generator is mounted on a trailer, make sure trailer
complies with all local and state safety transportation
laws. Follow the listed
guidelines for basic towing techniques.

■

Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating.”



Connect and test electric brake operation.



Secure portable power cables in cable tray with tie

is not to exceed 15 MPH or less depending on type of
terrain.

■

■

Use the trailer’s swivel jack to adjust the trailer height to

■

Avoid sudden stops and starts. This can cause skidding,
or jack-knifing. Smooth, gradual starts and stops will
improve towing.

■

Avoid sharp turns.

■

Trailer should be adjusted to a level position at all times
when towing.

■

Raise and lock trailer wheel stand in up position when

TLG-12SPX4— OPERATION AND PARTS MANUAL — REV. #1 (12/17/09) — PAGE 15

TLG-12SPX4 — INSTALLATION

Outdoor Installation

Install the generator in a area that is free of debris,
bystanders, and overhead obstructions. Make sure the
generator is on secure level ground so that it cannot slide or
shift around. Also install the generator in a manner so that
the exhaust will not be discharged in the direction of nearby
homes.

The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to

Generator Grounding

To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.

Article 250 (Grounding) of the National Electrical Code (NEC)
provides guide lines for proper grounding and specifies that
the cable ground shall be connected to the grounding system
of the building as close to the point of cable entry as
practical.

NEC articles 250-64(b) and 250-66 set the following
grounding requirements:

1. Use one of the following wire types to connect the
generator to earth ground.

engine and alternator parts.

a. Copper - 10 AWG (5.3 mm

CAUTION - EXHAUST HAZARD

Pay close attention to ventilation when operating the
generator inside tunnels and caves. The engine exhaust
contains noxious elements. Engine exhaust must be routed
to a ventilated area.

b. Aluminum - 8 AWG (8.4 mm2) or larger.

2. When grounding the generator (Figure 2) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the other
end of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth ground

Exhaust gases from diesel engines are extremely poisonous.
Whenever an engine is installed indoors the exhaust fumes
must be vented to the outside. The engine should be installed

NOTE

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.

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.

When connecting the generator
to any buildings electrical
system ALWAYS consult with
a licensed electrician.

TLG-12SPX4 — GENERAL INFORMATION

TLG-12SPX4 Whisperwatt™ Series Familiarization
Generator

The MQ Power Model TLG-12SPX4 is a 13 kW

generator

(Figure 3) 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.

Generator Control Panel

The “Engine Operating Panel” is provided with the following:

Open Delta Excitation System

The generator is equipped with the state of the art "

Delta

" excitation system. The open delta system consist of
an electrically independent winding wound among stationary
windings of the AC output section.

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.

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.

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 "
according the demands of the required load.

The TLG-12SPX4 is powered by a 3 cylinder, water cooled,

Kubota Model D902 diesel engine

to meet every performance requirement for the generator.
Reference Table 2 for engine specifications.

In keeping with MQ Power's policy of constantly improving
its products, the specifications quoted herein are subject to
change without prior notice.

Electric Governor System

The electric governor system controls the RPMs of the en­gine. When the engine demand increases or decreases, the
governor system regulates the frequency variation to ±.25%.

Extension Cables

When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to a
minimum. Use the cable selection chart (Table 6) as a guide
for selecting proper extension cable size.
