      Information

      Information

      Overview Manuals Common Applications Product Precautions
      9907-186 drives the documented GS3/LQ liquid-fuel metering valve from the control-system command signal.
      • Converts the control command into valve position
      • Returns documented position feedback
      • Provides shutdown/reset and fault interfaces
      • Supports integrated liquid-fuel metering

      The driver interfaces the 4-20 mA command with the electrically actuated valve and returns position and fault information. Commissioning verifies polarity, valve cable, feedback calibration, shutdown behavior and controlled stroking.

      Important Notice: Confirm WOODWARD 9907-186, GS3/LQ driver and valve, 18-32 V DC supply, 4-20 mA command and feedback, shutdown/reset and fault contacts, valve cable, grounding, calibration and controlled stroke results before commissioning.
