STANDARD FEATURES
1. ENGINE
Heavy duty industrial EPA compliant
diesel engine.
1.1 Governor
Mechanical, compliant with BS5514,
Class A1.
1.2 Electrical System
12 volt DC. Energized to run shutdown
solenoid. Oil pressure and coolant
temperature/level shutdown switches
and gauge senders.
1.3 Derates
Genset power derates will be required in
accordance with engine manufacturers
above 30� C (86� F).
2. COOLING RADIATOR
Radiator and cooling fan complete with
protection guards, designed to cool
the engine in ambient temperatures
up to 49� C (120� F).
3. ENGINE FILTRATION SYSTEM
Cartridge type dry air filters with
restriction indicator. Racor fuel filter in
addition to engine filter. Cartridge type
fuel filters and full flow lube oil filters.
All filters have replaceable elements.
4. EXHAUST SYSTEM
Critical Silencer with flexible connector.
All internal pipework lagged.
5. ELECTRICAL SYSTEM
12 volt system with battery charging
alternator, and starter motor on engine,
battery rack mounted on the generator
set baseframe and battery charger
mounted on control panel. Battery rack
will accept a variety of battery sizes.
6. GENERATOR
Screen protected and drip-proof, self
exciting, self-regulating brushless
generator with fully interconnected
damper windings, IC06 cooling system
and sealed-for-life bearings.
Switchable voltage output.
6.1 Insulation System
The insulation system is Class H.
Windings are impregnated in a triple dip
thermo-setting moisture, oil and acid
resisting polyester varnish. Heavy coat
of anti-tracking varnish for additional
protection against moisture or
condensation.
6.2 Electrical Characteristics
Electrical design in accordance with
BS5000 Part 99, IEC60034-1, EN61000-6,
NEMA MG-1.22.
6.3 Automatic Voltage Regulator (AVR)
The fully sealed automatic voltage
regulator maintains the voltage within
the limits of � 0.5% at steady state from
no load to full load.
Nominal adjustment is by means of
a trimmer incorporated in the AVR.
The panel door incorporates an
additional voltage adjustment
potentiometer.
6.3.1 Permanent Magnet Generator
Providing 350% short circuit capabilities,
enhanced motor starting and non-
linear loading performance.
6.4 Waveform Distortion, THF and
TIF Factors
The total distortion of the voltage
waveform with open circuit between
phases or phase and neutral is in the
order of 1.8. On a 3-phase balanced
harmonic-free load the total distortion
is 4%. Machines are designed to have
a THF less than 2% and a TIF less than
50. A 2/3 pitch factor is standard on all
stator windings.
6.5 Radio Interference
Suppression is in line with the
provisions of EN61000-6.
7. MOUNTING ARRANGEMENT
7.1 Baseframe
The complete generator set is mounted
on a heavy duty fabricated steel
baseframe. The baseframe includes
a UL listed closed top fuel tank and
incorporates specially designed
lifting points.
7.2 Coupling
The engine and generator are directly
coupled by means of an SAE flange
so that there is no possibility of
misalignment after prolonged use.
The engine flywheel is flexibly coupled
to the generator rotor and a full torsional
analysis has been carried out to
guarantee no harmful vibration
will occur in the assembly.
7.3 Anti-Vibration Mounting Pads
Captive anti-vibration pads are affixed
between engine/generator feet and the
baseframe ensuring complete vibration
isolation of the rotating assemblies and
enabling the machine to be placed on
an uneven surface without detrimental
effects.
7.4 Safety Guards
The fan, fan drive and battery charging
generator drive are fully guarded for
personnel protection. Heat guards
protect personnel from the exhaust
pipe. All guards are to OSHA standards.

manuals, circuit wiring diagrams, and
instruction leaflets is provided.
11. SOUND ATTENUATED
ENCLOSURES
A noise reducing enclosure surrounds
the entire generator set. Combined with
a critical engine silencer this provides
an overall noise reduction from 65 to
68 dBA at 23 feet through the range.
12. FACTORY TESTS
The generator set is load tested before
dispatch. All protective devices, control
functions and site load conditions are
simulated and the generator and its
systems checked, proved and then
passed for dispatch. A test certificate
can be provided upon request.
13. EQUIPMENT FINISH
All sheet metal components including
the enclosure and the base tank are fully
degreased, phosphated and chromated
for anti-corrosive protection prior to
painting with polyester powder.
The powder is cured at a temperature of
200� C (392� F) to ensure maximum scuff
resistance and durability. All fasteners
are electroplated. The engine and
generator are thoroughly cleaned and
finished in temperature controlled
ovens with industrial high gloss
polyurethane paint.
