• PTO options: 12- or 24-volt electric clutch

Alternator Features

• NEMA MG1, IEEE, and ANSI standards compliance for temperature rise and motor starting.
• Capable of sustained line-to-neutral short circuit current of up to 300% of the rated current for up to 2 seconds. Capable of sustained short circuit current of up to 300% of the rated current for up to 10 seconds for 3 phase connections. (IEC 60092-301 short-circuit performance.)
• Sustained short-circuit current enabling downstream circuit breakers to trip without collapsing the alternator field.
• Self-ventilated and dripproof construction.
• Vacuum-impregnated windings with epoxy varnish for dependability and long life.
• Superior voltage waveform from a two-thirds pitch stator and skewed rotor

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
• Alarm 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
• Automatic Restart. The controller automatic restart feature initiates the start routine and recrank after a failed start
• Cyclic The controller has programmable cyclic cranking.
• ECM The controller displays engine ECM fault code descriptions to help in engine troubleshooting.
• Engine Start 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
• Historical Data Total number of successful starts of the generator is recorded and displayed.
• Integrated Hybrid Voltage The voltage regulator provides ±0.5% no-load to full-load RMS voltage regulation with three-phase sensing.
• Lamp Press the alarm silence/lamp test button to verify functionality of the indicator lights.
• LCD Adjustable contrast for improving visibility.
• Measurement The controller provides selection of English or metric displays.
• Power Controller graphical display provides voltage, current, power factor, kW, kVA, and kVAR.
• Programming Access (USB). Provides software upgrades and diagnostics with PC software
• 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
• Run Time The generator set run time is displayed.
• Time Delay Engine Cooldown (TDEC). The TDEC provides a time delay before the generator set shuts
• Time Delay Engine Start (TDES). The TDES provides a time delay before the generator set
• Voltage Selection 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
