MOD CHOKE T

What does FF89 mean?

An overtemperature condition has been detected in the choke of the liquid-cooled R8i inverter module of the ABB ACS800 drive. This indicates that the choke's operating temperature has exceeded its safe limit, which can lead to reduced performance or damage.

• Malfunction or blockage of the inverter cooling fan, reducing airflow to the choke area.
• Elevated ambient temperature within the drive enclosure or surrounding environment.
• Issues with the liquid cooling system, such as low coolant flow, leaks, or insufficient cooling capacity.

Click steps to track your progress.

1. 1

   Check the inverter cooling fan for proper operation, ensuring it rotates freely and provides adequate airflow.

2. 2

   Verify the ambient temperature around the ACS800 drive enclosure, ensuring it is within specified operating limits.

3. 3

   Check the liquid cooling system for proper operation, including coolant flow, temperature, and any visible leaks.

4. 4

   Verify coolant levels and ensure the pump for the liquid cooling system is functioning correctly.
