Over-voltage of Capacitor Module (ECM)

What does 7 mean?

The voltage across the Capacitor Module of the ECM has exceeded its maximum safe operating voltage. This indicates an issue with charge control or excessive regenerative energy.

• The voltage across the capacitor module exceeds its maximum rated voltage.
• External voltage surge applied to the capacitor module.
• Faulty capacitor module components (e.g., series elements).
• Incorrect operation of balancing circuits within the module.
• Overcharging of the capacitor bank.

1. 1

   Inspect the Capacitor Modules for signs of bulging or damage.

2. 2

   Check the ECM control module's charging and discharge control circuits.

3. 3

   Verify the operation of the regenerative discharge unit if connected.
