Heavy duty industrial EPA compliant diesel engine.
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.
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.
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
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.
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.
8. FUEL SYSTEM
Fuel feed and return lines to the engine are terminated at the baseframe mounted 24 hour extended capacity fuel tank. The entire fuel system is surrounded by a catchment area to prevent leakage. 3-way valves to allow connection of auxiliary fuel tank.
9. CONTROL SYSTEM
9.1 Control Panel
Set mounted autostart panel in a vibration isolated NEMA 1 sheet steel enclosure with a hinged lockable door. a. DC and AC Wiring Harnesses
DC and AC wiring harnesses utilizing industrial type multi-pin connectors
to permit fast fault finding.
9.2 Circuit Breaker
3-pole UL CSA listed molded case circuit breaker mounted on the generator set in a vibration isolated NEMA 1 distribution panel.
9.3 Small power receptacles housed in a NEMA 1 distribution panel. Receptacles accept industry standard male plugs. Each receptacle is protected by a miniature circuit breaker which also acts as an on/off switch.
A full set of operation and maintenance manuals, circuit wiring diagrams, and instruction leaflets are 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.
The equipment meets the following standards: BS4999, BS5000, BS5514, IEC60034, EN61000-6, NEMA MG-1.22.
Full manufacturer's warranty.
