Description:

This code indicates that the spool of the Selective Control Valve III (SV III) is under-shooting its desired position.

Reaction:

Failure to reach the commanded position can result in incomplete or ineffective valve operations, impacting overall performance.

Recommendations:

• Calibrate Spool Movement:
  • Recalibrate the SV III to ensure it can reach the commanded positions accurately.
• Inspect for Obstructions:
  • Check for any mechanical obstructions that might prevent the spool from reaching its target position.
• Check Hydraulic System:
  • Ensure the hydraulic system is providing adequate pressure and flow to achieve the commanded positions.

Note:

If multiple valves generate this code, refer to the Operator’s Manual to determine the correct flow settings based on total flow demand.
