Details and Specifications

Included Accessories

Sound Shield 

Provides for highly effective silencing, ease of access for engine/generator servicing, low maintenance, excellent durability, and safety. The sound shield’s customer connection panel includes connections for the following: 

  • Battery (positive and negative) 
  • Equipment ground  
  • Fuel inlet and return
  • Seawater inlet 
  • Water-cooled exhaust outlet 
  • Oil drain 
  • Customer load lead access 
  • Customer interface 

Siphon Break 

Mandatory kit on generators installed below the waterline. Prevents the siphoning of flotation water into the engine. 

Line Circuit Breaker 

Protect the generator from extreme overload. 

Engine Features 

  • Low oil pressure shutdown 
  • High engine temperature shutdown 
  • Low seawater pressure shutdown 
  • Vibromount 
  • Belt guard 
  • Disposable oil filter 
  • Oil drain valve 
  • Disposable fuel filter 

Alternator Features 

  • Brushless, rotating field design permits power to be obtained from stationary leads. 
  • Windings are vacuum impregnated with epoxy varnish for  dependability and long life. 
  • Rotors are dynamically balanced to minimize vibration. 
  • Copper windings ensure minimal heat buildup. Insulation meets    NEMA standards for class H insulation. 
  • Direct connected to the engine, the generator has sealed precision  ball bearings with a precision-machined steel sleeve in the end bracket to prevent shaft misalignment and extend bearing life. 
  • Mounted on a drip-proof tray. 
  • Equipped with a four-lead reconnectable stator. 
  • Capable of sustained line-to-neutral short circuit current of up to 300% of the rated current for up to 2 seconds. (IEC 60092-301 short-circuit performance.) 

Decision-Maker® 3500 Controller 

Provides advanced control, system monitoring, and system diagnostics for optimum performance and compatibility. The  Decision-Maker® 3500 controller uses a patented hybrid voltage regulator and unique software logic to manage alternator thermal  overload protection features normally requiring additional hardware. Additional features include: 

  • AC Output Voltage Regulator Adjustment. The voltage adjustment provides a maximum adjustment of ±10% of the system voltage. 
  • Alarm Silence. The controller can be set up to silence the alarm horn only when in the AUTO mode for NFPA-110 application or Always for user convenience. 
  • Alternator Protection. The controller provides generator set overload and short circuit protection matched to each alternator for the particular voltage/phase configuration. 
  • Automatic Restart. The controller automatic restart feature initiates the start routine and recrank after a failed start attempt. 
  • Cyclic Cranking. The controller has programmable cyclic cranking. 
  • ECM Diagnostics. The controller displays engine ECM fault code descriptions to help in engine troubleshooting. 
  • Engine Start Aid. The configurable starting aid feature provides customized control for an optional engine starting aid. 
  • Event Logging. The controller keeps a record (up to 1000 entries) for warning and shutdown faults. This fault information becomes a stored record of system events and can be reset. 
  • Historical Data Logging. Total number of successful starts of the generator is recorded and displayed. 
  • Integrated Hybrid Voltage Regulator. The voltage regulator provides ±0.5% no-load to full-load RMS voltage regulation with three-phase sensing. 
  • Lamp Test. Press the alarm silence/lamp test button to verify functionality of the indicator lights. 
  • LCD Display. Adjustable contrast for improving visibility. 
  • Measurement Units. The controller provides selection of English or metric displays. 
  • Power Metering. Controller graphical display provides voltage, current, power factor, kW, kVA, and kVAR. 
  • Programming Access (USB). Provides software upgrades and diagnostics with PC software tools. 
  • Remote Reset. The remote reset function supports acknowledging and resetting faults and allows restarting of the generator set without going to the master control switch off/reset position. 
  • Run Time Hourmeter. The generator set run time is displayed. 
  • Time Delay Engine Cooldown (TDEC). The TDEC provides a time delay before the generator set shuts down. 
  • Time Delay Engine Start (TDES). The TDES provides a time delay before the generator set starts. 
  • Voltage Selection Menu. This menu provides the capability to switch the generator output voltage. NOTE: Generator set output leads may require reconnection. 
  • Paralleling Functions: 
      • Bus sensing 
      • First on logic 
      • Synchronizing 
      • Communication based isochronous load sharing 
      • Droop load sharing 
      • External controlled load sharing via analog bias signals
