What does rAME mean?
A fault has been detected in the keypad's Random Access Memory (RAM), which is used for temporary data storage during operation. This indicates an internal hardware failure within the keypad.
Common Causes
- Internal hardware failure of the keypad's Random Access Memory (RAM) chip.
- Corrupted data in RAM due to power supply fluctuations or electromagnetic interference (EMI).
- Keypad internal processing error leading to an invalid memory access.
- Component aging or manufacturing defect affecting RAM stability.
