Idle/Rated Relay Output The EGCP-2 can be configured to provide a relay output, which will signal the engine electronic speed control to change from idle to rated speed operation. When configured for this output, Discrete Output 12 will energize to provide the idle to rated indication. The idle to rated indication takes place after a successful start (generator above crank cutout speed) has occurred, the engine is operating at, or above the idle speed set point, and the idle delay time set point has expired.

Generator Voltage Control

The EGCP-2 has the ability to control the voltage of the generator set. This ability is used to control four separate operations that require generator voltage adjustment: 1. Manual voltage adjustment 2. Voltage Matching during Synchronization across the generator or mains breaker 3. Reactive Load sharing between multiple units on an isolated bus 4. Reactive Load control while in parallel with the mains. The generator voltage, or reactive load (depending on the operation) is adjusted by injecting a voltage bias signal to the Automatic Voltage Regulator. The EGCP2 can be set for ±1 Vdc, ±3 Vdc, and ±9 Vdc outputs. The span of the output is selected by the “Voltage Bias Type” configuration menu item in the EGCP-2.

Select the proper voltage range input 

as recommended by the AVR manufacturer. Generator Voltage can be manually controlled from the Voltage Raise and Voltage Lower Discrete inputs to the EGCP-2. The rate of change for manual voltage adjustment is set in the Reactive Load Control tuning menu, at the Voltage Ramp Time set point. The voltage ramp time is the amount of time it will take for the EGCP-2 to send a 0 to 100%, or 0 to –100% voltage bias signal to the AVR. When operating in the TEST mode, manual voltage adjustment is only allowed through the voltage raise and lower inputs. This allows testing of the Voltage Bias output, and generator voltage levels prior to operation with load on the generator
