RAM Anomaly (Remote Display)

What does rAM.E mean?

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.

• Internal Random Access Memory (RAM) data corruption within the remote display unit due to transient errors or hardware degradation.
• Manufacturing defect in the RAM chip of the display unit, causing unreliable data storage and retrieval.
• Transient power disturbances (sags, surges) affecting the display's control power supply (e.g., 24VDC), leading to memory corruption.
• Electromagnetic discharge (ESD) damage to the display's internal circuitry, impacting RAM functionality.
• Critical internal hardware malfunction within the display terminal's memory components preventing proper operation.

Click steps to track your progress.

1. 1

   1. Power cycle the remote display unit by physically disconnecting it from the drive for at least 30 seconds and then reconnecting it.

2. 2

   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. 3

   3. Ensure proper static discharge (ESD) precautions are followed when handling or installing the remote display unit to prevent future damage.

4. 4

   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. 5

   5. This fault strongly indicates a hardware malfunction within the remote display's memory components; prepare for replacement of the remote display unit.
