Product Introduction
The controller is engineered to manage prime mover fuel actuators to maintain constant engine speed and effectively distribute active loads among parallel-running generators. By continuously monitoring system frequency and inter-unit load sharing signals, it dynamically adjusts fuel delivery to prevent circulating currents and imbalances. Its heavy-duty electronic design guarantees reliable operation under fluctuating load conditions and harsh operational environments.
Product Instructions
- Verify that all power sources to the control panel are completely shut off before initiating any installation or wiring tasks.
- Securely mount the device onto a standard mounting plate or DIN rail inside a protective, vibration-isolated electrical enclosure.
- Connect the DC operating power, speed sensor inputs, actuator outputs, and load sharing interconnect lines strictly in accordance with the official wiring diagram.
- Double-check all terminal connections for tightness and proper polarity before energizing the system.
- Power on the unit and perform initial calibration adjustments for idle speed, rated speed, and load gain settings according to system requirements.
Product Precautions
- Ensure the operating voltage matches the device specifications precisely to prevent electrical damage to internal components.
- Avoid exposing the unit to excessive moisture, condensation, corrosive vapors, or high ambient temperatures.
- Route all low-level signal and load sharing lines away from high-voltage cables and heavy inductive loads to prevent electromagnetic interference.
- Perform periodic inspections of terminal screws and wiring integrity to maintain continuous and reliable system performance.
