Maintenance Counter 1 Fault
Vacon · 100 FLOW Application Guide
What does 1302 mean?
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.
Common Causes
- 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.
Repair Steps & Checklist
Click steps to track your progress.
- 1
1. Immediately identify the component monitored by Maintenance Counter 1 and assess its operational status for imminent failure.
- 2
2. Execute the overdue critical maintenance procedure for the specified component.
- 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. Review and adjust parameter P7-02 (Maintenance Counter 1 Fault Limit) to ensure it aligns with safe and reasonable operating intervals.
- 5
5. Verify that any physical sensor inputs contributing to Maintenance Counter 1 are functioning correctly and calibrated accurately.
