If the controller incoming line fuse blows when power is applied to the controller, there may be faulty incoming A-C line wiring or an inadvertent ground in the branch circuit or within the controller enclosure. If this occurs, check all incoming A-C wires and terminations to and within the controller, correct any faulty wiring and remove any grounds, and/or replace the blown fuse. When the Start command is given and the controller incoming line fuse blows, there are five possible issues going on. For one, the motor armature may be shorted or grounded. The SCR may be shorted or the regulator may be faulty. The connection may be loose, corroded, or faulty, or the wiring may be grounded or incorrect. There may be a sudden, severe application of overload to the motor. Lastly, the circuit board may be faulty. If the circuit board, regulator, or SCR are faulty, the user must replace the entire controller. Alternatively, you may have to replace a blown fuse.
