Description:

This error code indicates that the Selective Control Valve IV (SV IV) is not going into the FLOAT position as commanded. This can be caused by mechanical issues within the valve, electrical faults, or control lever problems.

Reaction:

The equipment may exhibit improper hydraulic functions, specifically in tasks that require the float position for operation. A warning will be displayed on the control panel.

Recommendations:

• Inspect Valve Mechanism:
  • Check for any mechanical obstructions or damages within the valve mechanism that could prevent it from reaching the float position.
• Verify Electrical Connections:
  • Ensure all electrical connections to the SV IV are secure and free of corrosion or damage.
• Check Control Lever:
  • Inspect the control lever for any mechanical or electrical issues that might be preventing it from properly commanding the float position.
• Update Software:
  • Ensure the control unit software is up-to-date to prevent any software-related issues.

Note:

Regular maintenance and inspection of the hydraulic system and control mechanisms can prevent such issues.
