Pr5-Trip (Communication error with EEPROM in control unit)

What does 79 mean?

This fault indicates a communication error with the EEPROM (Electrically Erasable Programmable Read-Only Memory) located in the control unit, affecting both KPS-600 and KSD devices. This can lead to issues saving or retrieving critical operational data and parameters, potentially causing incorrect device behavior or preventing startup.

• Pr5-Trip: Communication error with EEPROM in the control unit (P1-13).
• Corrupted data in the control unit's EEPROM.
• Loose connection to the EEPROM module.
• Failed EEPROM chip.

Click steps to track your progress.

1. 1

   Perform a power cycle of the control unit to attempt to re-establish communication.

2. 2

   Check for any visible damage or loose connections to the control unit's internal memory module, if accessible for inspection.

3. 3

   Attempt to re-upload the control unit's configuration data from a valid source.
