Control System - PCC3201 P
C
The PowerCommand™ 3201 Control is a microprocessor-based generator set monitoring, and control
system. The control provides an operator interface to the genset, digital voltage regulation, digital
governing and generator set protective functions.
The PowerCommand™ 3201 generator set control is suitable for use on a wide range of generator sets in
non-paralleling and paralleling applications
The PowerCommand™ Control can be configured for any frequency, voltage and power connection
configuration from 120 to13,800 VAC for for 50Hz or 60Hz operation.
Power for the control is derived from the generator set starting batteries. The control functions over a
voltage range from 8VDC to 35VDC.
Major Features
• Digital Full Authority Electronic Engine Controls for Cummins HPI-PT fuel systems
• Digital Voltage Regulation with 3-phase sensing
• AmpSentry™ Protection for true alternator overcurrent protection.
• Analog and Digital AC Output Metering.
• Battery Monitoring System to sense and warn against a weak battery condition.
• Digital Alarm and Status Message Display
• Generator set Monitoring: Displays status of all critical engine and alternator generator set functions.
• Smart Starting Control System: Integrated fuel ramping to limit black smoke and frequency overshoot,
• Advanced Serviceability using InPower, a PC-based software service tool.
• PowerCommand Network (optional) Provides LonMark interface to external devices
Control System
Includes all functions to locally or remotely start and stop, and protect the generator set.
Control Switch - RUN/OFF/AUTO
