Overview
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The GCP-20 series generator set controllers provide the following functions:
Gen-set control
• Engine and generator protection
• Engine data measurement -
○ including oil pressure and oil temperature, coolant temperature, battery voltage, speed,
service hours, etc.
• Generator data measurement -
○ including. voltage, current, power, kvar, kW, kWh, etc.
• Engine start/stop procedure
• Alarm display with breaker trip and engine shutdown
• Emergency operation with mains failure recognition and automatic engine start incl. change-over-logic
• Control of voltage, frequency, real power and reactive power
• Real power and reactive power load sharing including load management with automatic start/stop of others
and redundant gensets.
• Synchronization of one or two power circuit breakers
• CAN bus communications to engine controllers and plant management systems
Type designation is as follows:
GCP- 22 4 5 -h0018 B/ BPD +ABDEF..Z
