Control System - PCC3100 P
C
The PowerCommand 3100 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 3100 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 Governing and Voltage Regulation, including digital overcurrent fault regulation.
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
OFF Mode - the generator set is shut down and cannot be started
RUN mode the generator set will execute its start sequence
AUTO mode, the generator set can be started with a start signal from a remote device
LED Indicating Lamps - includes LED indicating lamps for the following functions:
Not-in-auto mode
Common wiring
Shutdown
Phase and scale indication
Fault reset switch. Allows the opperator to reset the control after warning or shutdown
Emergency stop switch - imediately shuts down the generator set operation
Base Engine Protection:
Overspeed shutdown
Low Oil Pressure Warning / Shutdown
High Engine Temperature Warning / Shutdown
Underspeed / Sensor Fail Shutdown
Fail to Start / Fail to Crank
Low / high battery voltage
Options
Integrated PowerCommand Digital Paralleling Controls
Key Type Mode Selector Switch
