Thanks for taking the time to make the video for others. Be interested to know what you found out after letting it run a while and if you discovered if the winding insulation was deteriorating via the megger test at 500V. After it ran a while, the amperage imbalance or lack their of. You know, each legs amp added together, divided by 3, and then the % of deviation for each lag from the average. I mean thats just what came to my mind as I was viewing video. Enjoyed the low voltage portion the most. I've seen some motor overloads that have a N.O. contact that is wired to the contractor's auxiliary to "cut" the low voltage to the contactor coil, but I didn't see that on the video. So the motor contactor in your situation was still energized? Correct? Again, thanks and keep in the training mode. Jeff

Meg tested @ 500 & 1000 volts and the motor passed, the amperages was with tolerance, the overload doesn’t break the line voltages (please watch video again and look closer at OL) it only breaks low voltage (24v) from Q5 output

Good video. just an FYI they run those motor leads through that metal flex and it rubs the leads inside causing them to arc on the metal jacket when the unit vibrates while running. I had a unit tripping like this just recently thinking it was the overload just to come back with the overload tripped and a blown fuse

I have a Liebert Model: PX011UA1A8B679, the set point is 23 degrees Celsius and 12 dew point, the problem is that the temperature drops to 18 and the humidity does not drop below 70%, it has resistors, 24 volts do not reach the coil of the resistance contactor, the password I entered is 5010, Greetings.

Does your liebert have dehumidifier option? If yes lower the humidity setpoint. Here it will run the cooling and the electric heaters simultaneously after room temperature setpoint has been obtained, to remove humidity. In the event your liebert don't have dehumidifier option or the electric heater don't work, this will cause room temperature to fall well below setpoint while in dehumidifier mode
@D2DNYAC

So you can go into setup option and disable dehumidifier or raise humidity setpoint however not to high because now you activate humidifier mode necessary if it available

One would think that the overload at the time of your checking the motor windings would have been open. Suggest in future you make this check at the load side of the overload
