SV2 004084.07 – SV II Not in Float Position

SV2 004084.07 (SV2 4084.07)

Code: 004084.07

Shortcode: 4084.07


The error code SV2 004084.07 indicates that the Selective Control Valve II (SV II) is not achieving the FLOAT position. This issue can occur due to mechanical obstructions, hydraulic system malfunctions, or electrical control faults that prevent the valve from moving into the FLOAT position.


When this error code is triggered, the equipment will be unable to set the SV II into the FLOAT position, affecting the hydraulic system’s performance, particularly in operations requiring the FLOAT mode.


Inspect Mechanical Components:

  • Check for any mechanical obstructions or damage to the valve that may prevent it from reaching the FLOAT position.
  • Ensure that the valve is free from debris and other blockages.

Verify Hydraulic System:

  • Inspect the hydraulic system for adequate fluid levels and pressure.
  • Check for leaks or other signs of hydraulic fluid loss.

Check Electrical Controls:

  • Verify that the electrical control system is functioning correctly.
  • Inspect wiring and connections for any damage or corrosion. Repair or replace as necessary.

Perform Calibration:

  • Calibrate the SV II to ensure it can reach all designated positions, including FLOAT.
  • Follow the manufacturer’s guidelines for proper calibration procedures.


Regular maintenance and calibration of the SV II and related hydraulic systems are crucial to ensure reliable operation and to prevent issues with achieving the FLOAT position.
