Description
Woodward 8273-042
Technical Specifications
- Part Number: 8273-042
- Base Series: Woodward 8273
- Application: Reciprocating Gas Engines / Gas Turbines
- Power Supply: 24 Vdc nominal
Functional Features
- Engine Management: Controls fuel valve positioning for precise speed and load regulation.
- Load Sharing: Supports isochronous and droop load sharing for multi-engine paralleling applications.
- Safety Integration: Interfaces with dedicated safety systems for overspeed and low-oil-pressure shutdowns.
Application Scenarios
Extensively used in distributed power generation, biogas plants, and mechanical drive applications powered by large reciprocating gas engines.
Performance Parameters
- Speed Regulation: Isochronous speed control with less than 0.25% steady-state error.
- Transient Response: Rapid fuel valve actuation to minimize frequency deviation during load steps.
Material Composition
Conformal-coated electronics housed in a durable, vibration-resistant enclosure designed for engine-mounted environments.
Structural Characteristics
- Mounting: Panel or rack mountable with secure locking mechanisms.
- Status Indicators: Front-panel LEDs for power, run, alarm, and trip status.
Working Principle
Monitors engine speed and load via magnetic pickups and analog inputs. The microprocessor calculates the required fuel flow to maintain the setpoint, outputting a PWM or analog signal to the fuel actuator.
Installation Requirements
- Vibration: Ensure mounting location minimizes exposure to excessive engine vibration.
- Wiring: Route sensor cables away from high-voltage ignition wiring to prevent EMI.
Usage Precautions
- Sensor Gap: Verify magnetic pickup air gaps are set according to manufacturer specifications.
- Firmware: Use only approved firmware versions to maintain safety and performance.
