Description:

This error code, SCO 516455.18, indicates that both the supply voltage (BAT) is too low (9–11 volts) and the hydraulic oil temperature is between -25°C (-13°F) and -15°C (5°F).

Reaction:

When this fault is detected, the control software may have limited functionality or may cease to function altogether, resulting in limited or no function of the selective control valve (E-SCV X).

Recommendations:

• Increase Supply Voltage:
  • Ensure that the battery is properly charged and that the charging system is working correctly. Replace the battery if it is old or unable to hold a charge.
• Warm Up Hydraulic Oil:
  • Operate the equipment in a warmer environment or use external heaters to raise the hydraulic oil temperature above -15°C (5°F).
• Inspect Electrical Connections:
  • Check all electrical connections related to the stepper motor and battery for tightness and cleanliness. Clean and secure any loose or corroded connections.
• Monitor Voltage and Temperature:
  • Continuously monitor the supply voltage and hydraulic oil temperature to ensure they stay within the recommended range.

Note:

Preventive Maintenance:

• Regular inspections and maintenance of the electrical and hydraulic systems can help prevent issues related to low voltage and low temperature.
