Control system
The PowerCommand control system is an integrated microprocessor based generator set control system providing voltage regulation, engine protection, alternator protection, operator interface and isochronous governing.
AmpSentry – Includes integral AmpSentry protection, which provides a full range of alternator protection functions that are matched to the alternator provided.
Power management – Control function provides battery monitoring and testing features and smart starting control system.
Advanced control methodology – Three phase sensing, full wave rectified voltage regulation, with a PWM output for stable operation with all load types.
Communications interface – Control comes standard with PCCNet and Modbus interface.
Regulation compliant – Prototype tested: UL, CSA and CE compliant.
Service - InPower PC-based service tool available for detailed diagnostics, setup, data logging and fault simulation.
Reliable design – The control system is designed for reliable operation in harsh environment.
Multi-language support
Operator panel features
Operator panel features – The operator panel, in addition to the alternator, displays the Utility/AC Bus data.
Operator/display functions
- 320 x 240 pixels graphic LED backlight LCD
- Auto, manual, start, stop, fault reset and lamp test/panel lamp switches
