Lr = Locked Rotor: Overloaded while PMA is running
LU = Locked Up: Overload at PMA startup
SC = Short Circuit: Short typically from controller to PMA
SU = Shorted Upper: Short typically in controller
OC = Open Circuit: Broken connection to PMA
Er = Extended Run: No power change for 60 minutes
HO = Hot Operation: Excessive controller temp / fan protection
