tribution of forces without the block being unnessarily heavy.

– Wet, replaceable cylinder liners– Piston cooling for low piston temperature

and reduced ring temperature– Tapered connecting rods for increased pis-

ton lifetime– Crankshaft induction hardened bearing

sur fac es and fi llets with seven bearings for mod er ate load on main and high-end bear- ings

– Case hardened and Nitrocarburized trans- mis sion gears for heavy duty operation

– Keystone top compression rings for long service life

– Viscous type crankshaft vibration dampers to withstand single bearing alternator tor sion al vibrations

– Replaceable valve guides and valve seats– Over head camshaft and four valves per cyl-

in der

Lubrication system– Full fl ow oil cooler– Full fl ow disposable spin-on oil fi lter, for ex-

tra high fi ltration– The lubricating oil level can be measured

during operation– Gear type lubricating oil pump, gear driven

by the transmission

Fuel system– Electronic high pressure unit injectors– Fuel prefi lter with water separator and wa ter-

in-fuel indicator / alarm– Gear driven low-pressure fuel pump– Fine fuel fi lter with manual feed pump and

fuel pressure switch

Cooling system– Effi cient cooling with accurate coolant con-

trol through a water distribution duct in the cylinder block. Reliable sleeve thermostat with minimum pressure drop

– Belt driven coolant pump with high degree of effi ciency

– Electronically controlled viscous fan drive provides lower noise and fuel consumption (optional).

– Coolant fi lter as standard

Turbo charger– Effi cient and reliable turbo charger– Electronically controlled Waste-gate– Extra oil fi lter for the turbo charger

Electrical system– Engine Management System 2 (EMS 2), an

electronically controlled processing system which optimizes engine performance. It also includes advanced facilities for diagnostics and fault tracing.

– Possibility to perform a start battery test ac-cording to the NCPA requirements via CAN bus signals.

– The instruments and controls connect to the engine via the CAN SAE J1939 interface, either through the Control Interface Unit (CIU) or the Digital Control Unit (DCU). The CIU converts the digital CAN bus signal to an anolog signal, making it possible to con-nect a variety of instruments. The DCU is a control panel with display, engine control, monitoring, alarm, parameter setting and di-agnostic functions. The DCU also presents error codes in clear text.

– Sensors for oil pressure, oil temp, boost pres sure, boost temp, coolant temp, fuel temp, water in fuel, fuel pressure and two speed sensors.

Features– Excellent load acceptance– Highly effi cient cooling system– Dual Speed 1500 / 1800 rpm– EMS 2– EU Stage 2 emission certifi ed– Wide range of optional equipment including visco fan.

HCI 534C/544C - Technical Data Sheet

HCI534C/544CSPECIFICATIONS & OPTIONS

STANDARDSNewage Stamford industrial generators meet therequirements of BS EN 60034 and the relevant sectionof other international standards such as BS5000, VDE0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.Other standards and certifications can be considered onrequest.

VOLTAGE REGULATORS

SX440 AVR - STANDARDWith this self-excited system the main stator providespower via the Automatic Voltage Regulator (AVR) to theexciter stator. The high efficiency semi-conductors ofthe AVR ensure positive build-up from initial low levelsof residual voltage.The exciter rotor output is fed to the main rotor througha three-phase full-wave bridge rectifier. The rectifier isprotected by a surge suppressor against surgescaused, for example, by short circuit or out-of-phaseparalleling.The SX440 will support a range of electronicaccessories, including a 'droop' Current Transformer(CT) to permit parallel operation with other acgenerators.If 3-phase sensing is required with the self-excitedsystem, the SX421 AVR must be used.

SX421 AVRThis AVR also operates in a self-excited system. Itcombines all the features of the SX440 with,additionally, three-phase rms sensing for improvedregulation and performance. Over voltage protection isprovided via a separate circuit breaker. An engine reliefload acceptance feature is built in as standard.

MX341 AVRThis sophisticated AVR is incorporated into theStamford Permanent Magnet Generator (PMG) controlsystem.The PMG provides power via the AVR to the mainexciter, giving a source of constant excitation powerindependent of generator output. The main exciteroutput is then fed to the main rotor, through a full wavebridge, protected by a surge suppressor. The AVR hasin-built protection against sustained over-excitation,caused by internal or external faults. This de-excitesthe machine after a minimum of 5 seconds.An engine relief load acceptance feature can enable fullload to be applied to the generator in a single step.If three-phase sensing is required with the PMG systemthe MX321 AVR must be used.We recommend three-phase sensing for applicationswith greatly unbalanced or highly non-linear loads.

MX321 AVRThe most sophisticated of all our AVRs combines all thefeatures of the MX341 with, additionally, three-phaserms sensing, for improved regulation and performance.Over voltage protection is built-in and short circuitcurrent level adjustments is an optional facility.

WINDINGS & ELECTRICAL PERFORMANCEAll generator stators are wound to 2/3 pitch. Thiseliminates triplen (3rd, 9th, 15th …) harmonics on thevoltage waveform and is found to be the optimumdesign for trouble-free supply of non-linear loads. The2/3 pitch design avoids excessive neutral currentssometimes seen with higher winding pitches, when inparallel with the mains. A fully connected damperwinding reduces oscillations during paralleling. Thiswinding, with the 2/3 pitch and carefully selected poleand tooth designs, ensures very low waveformdistortion.

TERMINALS & TERMINAL BOXStandard generators are 3-phase reconnectable with 12ends brought out to the terminals, which are mountedon a cover at the non-drive end of the generator. Asheet steel terminal box contains the AVR and providesample space for the customers' wiring and glandarrangements. It has removable panels for easyaccess.

SHAFT & KEYSAll generator rotors are dynamically balanced to betterthan BS6861:Part 1 Grade 2.5 for minimum vibration inoperation. Two bearing generators are balanced with ahalf key.

INSULATION/IMPREGNATIONThe insulation system is class 'H'.All wound components are impregnated with materialsand processes designed specifically to provide the highbuild required for static windings and the highmechanical strength required for rotating components.

QUALITY ASSURANCEGenerators are manufactured using productionprocedures having a quality assurance level to BS ENISO 9001.

The stated voltage regulation may not be maintained inthe presence of certain radio transmitted signals. Anychange in performance will fall within the limits ofCriteria 'B' of EN 61000-6-2:2001. At no time will thesteady-state voltage regulation exceed 2%.

NB Continuous development of our products entitles usto change specification details without notice, thereforethey must not be regarded as binding.
