This is a continuation of my earlier problem with the spindle speed on my HLV-H going to the fast stop without commanding it using the momentary rotary switch.
I found out what is wrong. The overload relay is blown on two of the three poles. Now, the question is why and what I should do. I have a new one on order; however, I don't want to fry that as well.
Here is what I think may have happened. I think the contactor for the jack screw drive moved the motor to the fast position and then stuck in that position. When this happened, the motor drew too much power and burned out the wires inside of the contactor.
Does this make sense? Is there a way to check to see if the motor is damaged?
