Schneider Electric · Altivar 312 Variable Frequency Drive
This error indicates that the remote display terminal has detected an internal Random Access Memory (RAM) anomaly. This points to a critical internal hardware malfunction within the display terminal's temporary data storage. The terminal's ability to process and display information will be impaired.
Click steps to track your progress.
1. Power cycle the remote display unit by physically disconnecting it from the drive for at least 30 seconds and then reconnecting it.
2. Monitor the quality of the incoming control power supply to the drive and, consequently, the display (e.g., 24VDC) for any sags, surges, or transients.
3. Ensure proper static discharge (ESD) precautions are followed when handling or installing the remote display unit to prevent future damage.
4. If the display has configurable internal settings, perform a factory reset via the display menu (if accessible) to clear any potentially corrupted volatile memory.
5. This fault strongly indicates a hardware malfunction within the remote display's memory components; prepare for replacement of the remote display unit.
