Maintenance Counter 2 Fault

What does 1304 mean?

Maintenance counter 2 has exceeded its programmed fault limit, indicating that the maintenance interval for the monitored component has been critically overdue. This fault state demands immediate action as continued operation without maintenance could compromise equipment integrity or lead to system failures.

• Operating hours or cycles tracked by Maintenance Counter 2 (Parameter P7-03) have critically surpassed the fault threshold (Parameter P7-05).
• The programmed fault limit for Maintenance Counter 2 (P7-05) is set inappropriately low, causing premature system shutdown.
• Essential maintenance for the monitored component was not performed for a significant period after its alarm state.
• Internal logic error or firmware bug causing Maintenance Counter 2 to accumulate counts too rapidly or erratically.

Click steps to track your progress.

1. 1

   1. Stop the process and immediately investigate the component or system monitored by Maintenance Counter 2 for potential failure.

2. 2

   2. Perform all necessary overdue critical maintenance procedures for the component associated with Counter 2.

3. 3

   3. Reset Maintenance Counter 2 by setting parameter P7-03 to 0 (or using a specific fault acknowledgement command from the HMI).

4. 4

   4. Carefully review and adjust parameter P7-05 (Maintenance Counter 2 Fault Limit) to prevent future unwarranted faults.

5. 5

   5. Conduct a thorough inspection of the monitored component to ensure it is operating within design specifications and safely.
