Control Overview
Introduction
The EGCP-2 is a microprocessor based complete generator load control and
engine management package designed for use with an Electronic engine speed
control and a separate voltage regulator. The control's functions include:
Engine Control
• Engine Pre-glow
• Fuel Solenoid Control
• Engine Starter Control
• KVA Controlled Cool-down Timer
• Oil Pressure Monitoring
• Water Temperature Monitoring
• Battery Voltage Monitoring
• Speed Monitoring with Overspeed Protection
• Idle/Rated Relay Output
Synchronizing
• Digital signal processing to eliminate problems induced in systems with high
harmonic content causing multiple zero crossing of voltage wave forms
• Adjustable maximum phase window, voltage window, and dwell times—
windows as small as 2° phase error and 1% voltage matching respectively
• Safe dead bus closing logic internal to the control
• Multiple shot re-closing with adjustable time delays, auto-resynchronizing,
and synchronizer time-outs all available
• Manual voltage and speed adjusts for manual synchronizing (Sync-Check
still active during manual parallels)
• Synchronization across generator and mains breakers
Real (kW) Load Control
• True RMS power calculations for rapid, accurate load control even in the
presence of harmonics
• Smooth user chosen ramp rates into and out of each mode of operation
• Isochronous load-sharing of up to 8 units based on percentage loading
(allows different rated machines to proportionally balance kW loads)
• Constant base loading for optimum fuel efficiency with discrete inputs to
change load levels remotely
• Import/Export control with an external watt transducer
• Soft Utility Transfer Function
• Externally adjustable Base Load or Process Reference Levels with
independent ramp rates
• kW droop provided for manual load control
