Actuator Loop Feedback Response and Dynamic Load Sharing

The Woodward 8406-113 utilizes dedicated speed bias output configurations (4-20 mA, 0-5 V, PWM, or +/-3 V) to deliver precise actuator loop feedback response during transient load changes. By calculating frequency differential and load proportions across interconnected generators via serial network lines, the internal control algorithm dynamically adjusts prime mover throttle inputs. This closed-loop speed bias mechanism stabilizes system frequency and minimizes proportional load errors across multiple parallel engine-generator sets.

Frequently Asked Questions

Q: What is the allowable input voltage range for powering the Woodward 8406-113 control module?

A: The module requires an external power supply source providing an operating input voltage between 18 VDC and 32 VDC.

Q: How are speed bias signals interfaced from the 8406-113 to the engine governor or actuator?

A: The unit features configurable analog and pulse outputs supporting standard signal types including 4-20 mA, 0-5 VDC, PWM, and +/-3 VDC to accommodate various electronic governor inputs.

Q: What environmental protection rating does the enclosure achieve?

A: When correctly mounted with appropriate panel sealing, the unit meets NEMA 4 standards for protection against ingress of falling dirt, water, and windblown dust.

Field Installation Guidelines

  • Mount the enclosure on a vertical panel using the designated mounting holes to satisfy NEMA 4 sealing standards.
  • Maintain separate routing paths for high-voltage power lines and low-level analog speed bias wires to prevent electromagnetic interference.
  • Ground all serial communication cable shields at a single point to avoid ground loops.
  • Verify DC power supply terminals observe correct polarity and supply voltage within 18-32 VDC limits prior to energizing the module.
