Description:

This error code indicates that the Selective Control Valve IV (SV IV) spool is undershooting its desired position. This could be due to calibration issues, mechanical problems, or insufficient hydraulic flow.

Reaction:

The valve may not perform as expected, leading to operational inefficiencies. A diagnostic warning will be displayed on the control panel.

Recommendations:

• Calibrate Valve:
  • Recalibrate the SV IV to ensure it reaches the commanded position accurately.
• Inspect Mechanical Components:
  • Check for any mechanical obstructions or wear that could prevent the valve from reaching its desired position.
• Verify Hydraulic Flow:
  • Ensure that the hydraulic flow to the valve is sufficient and correctly set. Refer to the Operator’s Manual for proper flow settings.
• Update Firmware:
  • Ensure the control unit firmware is up-to-date to prevent any software-related issues.

Note:

If multiple valves are generating this code, refer to the Operator’s Manual to determine the total flow demand and correctly set the flow.
