What to do if DAB Controller displays 'oF' error?
- RRobin ObrienAug 5, 2025
If the DAB Controller displays 'oF', it could be due to excessive power absorption or a blocked pump. First, check the type of connection (star or delta), verify the direction of rotation using parameter 'rt', and ensure the motor's current draw doesn't exceed the A.D.'s maximum supply. Also, inspect the impeller and motor for any obstructions or foreign objects, and check the motor connection phases.
