Maintenance Counter 1 Fault

Was bedeutet 1302 ?

Maintenance counter 1 has exceeded its programmed fault limit, which is typically higher than the alarm limit. This indicates that a critical maintenance interval has been significantly surpassed, potentially impacting equipment reliability or safety. This fault requires immediate attention to prevent operational issues.

• Operating hours or cycles tracked by Maintenance Counter 1 (Parameter P7-00) have critically exceeded the fault threshold (Parameter P7-02).
• The configured fault limit for Maintenance Counter 1 (P7-02) is set too low, triggering a fault instead of an appropriate warning.
• Required preventative maintenance for the component monitored by Counter 1 was significantly overdue following an alarm state.
• Accumulation of operating data by Maintenance Counter 1 is erroneous due to internal drive issue or sensor miscalibration.

1. 1

   1. Immediately identify the component monitored by Maintenance Counter 1 and assess its operational status for imminent failure.

2. 2

   2. Execute the overdue critical maintenance procedure for the specified component.

3. 3

   3. Reset Maintenance Counter 1 by writing 0 to parameter P7-00 (or by using a dedicated fault reset function from the HMI).

4. 4

   4. Review and adjust parameter P7-02 (Maintenance Counter 1 Fault Limit) to ensure it aligns with safe and reasonable operating intervals.

5. 5

   5. Verify that any physical sensor inputs contributing to Maintenance Counter 1 are functioning correctly and calibrated accurately.
