Great day Sir Jim, am so thankful that I visited your channel, your such a gift for us who are interested this kind of level. God bless and be safe always
Your awesome.. Wish are school touched on troubleshooting like this.. Starting a job at a steel mill.. I was told the will train me. Whatching videos like this brings new light on a, Hey man my button won't work... Seems overwhelming.. Hopefully I can keep my progress in check because the opportunity is there 😊
At 3:38 you said that you are simulating overload event by pressing test button on overload relay. How is than possible that NC 95 and 96 are still closed? Why is green led on? I'm confused. EDIT: I understand, there is path for current to flow because float switch is closed. NC 95 and 96 are open, but that is not the only path for the current to flow, there is still led.
Pressing the test button on the OL relay opens the NC 95 96 contacts. There is no path through M contactor coil. M primary contacts open. Current path through LED remains closed.
@@bigbadtech thanks for response! I edited post. In first place, I didn't see that there is still path for current to flow through led. Your videos are really gold!
