Description:

This error code indicates that the unswitched supply voltage for Selective Control Valve I (SV I) and Selective Control Valve II (SV II) is below 9.0 V. Low voltage can cause these valves to malfunction or operate inefficiently.

Reaction:

When this code is detected, the SCC will disable its functions, turning them off to prevent further issues.

Recommendations:

Check Power Supply:

• Verify that the power supply to SV I and SV II is stable and within the specified range. Replace the power supply if it is not providing sufficient voltage.

Inspect Voltage Regulator:

• Ensure the voltage regulator is functioning correctly. Replace if it is not maintaining proper voltage levels.

Inspect Wiring and Connectors:

• Check all wiring and connectors for SV I and SV II for signs of damage, poor connections, or corrosion. Repair or replace as necessary.

Monitor Voltage:

• Use a multimeter to monitor the voltage supplied to SV I and SV II, ensuring it stays within the acceptable range.

Consult Technical Support:

• If the issue persists, contact technical support for further diagnostics and assistance.

Note:

Ensuring stable voltage supply is essential for the proper operation of control valves.
