Description:

This fault code indicates that the PTH controller temperature is slightly low, falling below the normal operational range but not at a critical level. This can be due to minor environmental fluctuations or cooling system issues.

Reaction:

When this error is detected, the equipment continues to operate but logs the fault for monitoring purposes. There may be minor performance inefficiencies.

Recommendations:

Replace Controller:

• The primary recommendation is to replace the PTH controller to ensure normal operation.

Verify Environmental Conditions:

• Ensure the equipment is operating within the specified temperature range.
• Avoid exposure to extremely cold conditions and implement proper warming procedures if necessary.

Monitor System Performance:

• After replacing the controller, monitor the system to ensure normal operation and that the fault does not reappear.

Consult Technical Support:

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

Note:

Regular monitoring of environmental conditions and ensuring the equipment operates within specified temperature ranges can prevent such issues. Implement appropriate measures to maintain a stable operating temperature.
