Description:

This error code signifies that the Selective Control Valve IV (SV IV) spool is overshooting its desired position. This could be due to issues such as incorrect calibration, mechanical faults, or problems within the control system.

Reaction:

The valve may exhibit erratic movements, leading to potential operational issues. A diagnostic warning will appear on the control panel.

Recommendations:

• Calibrate Valve:
  • Recalibrate the SV IV to ensure it responds accurately to control commands.
• Inspect Mechanical Components:
  • Check the valve and related components for any mechanical faults or wear that could cause overshooting.
• Verify Control Signals:
  • Ensure that the control signals being sent to the SV IV are within the proper range and not causing overshooting.
• Update Firmware:
  • Make sure the control unit firmware is up-to-date to mitigate any software-related issues.

Note:

Proper calibration and regular maintenance of the control system can prevent overshooting issues.
