Energy Supply Stop (ECM)

¿Qué significa U ?

A potential difference across a capacitor module is more than 300V, indicating an energy supply issue or abnormal voltage condition.

• Charging current exceeds the allowed limit.
• Faulty charging circuit or power supply.
• Capacitor bank is not charging efficiently.
• Overcharging the capacitor module.

1. 1

   Measure the voltage across the capacitor modules to confirm it exceeds 300V.

2. 2

   Check the input power supply to the ECM for stable operation.

3. 3

   Verify the internal charging and discharge circuits of the ECM for proper voltage regulation.
