Schneider Electric · Altistart 22 Soft Starter
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.
Click steps to track your progress.
1. Perform a power cycle of the soft starter by removing all power for at least 30 seconds to clear temporary RAM data.
2. Disconnect and reconnect the keypad communication cable to ensure stable power delivery and signal integrity.
3. Monitor the power supply voltage to the keypad (if accessible) to ensure it is stable and within specification.
4. Replace the remote keypad unit, as a RAM trip typically indicates a non-recoverable internal hardware failure.
5. Check for any external sources of electromagnetic interference (EMI) near the keypad or its communication cable.
