Description:

This error code, SCO 523871.18, indicates that both the supply voltage (9–11 volts) and the hydraulic oil temperature (-25°C to -15°C) are too low for the stepper motor for E-SCV XIII. Low voltage and cold hydraulic oil can limit the motor’s functionality.

Reaction:

When this fault is detected, the selective control valve (E-SCV XIII) will have limited or no function.

Recommendations:

• Increase Supply Voltage:
  • Ensure that the supply voltage to the stepper motor is within the recommended range. Repair or replace the power supply components if necessary.
• Warm Up Hydraulic Oil:
  • Warm up the hydraulic oil to a temperature above -15°C (5°F) to ensure proper operation. Check for any issues in the heating system and repair or replace any faulty components.
• Monitor System Parameters:
  • Continuously monitor the supply voltage and hydraulic oil temperature to ensure they stay within the recommended ranges.
• Consult Technical Support:
  • If the issue persists, consult technical support for further diagnostics and assistance.

Note:

System Maintenance:

• Regular maintenance and monitoring of the power supply and hydraulic system can help prevent issues related to low voltage and cold temperatures.
