Wiring a Magnetic Reversing Motor Starter with Interlocks

In this guided application exercise we'll wire up and test a three wire magnetic motor starter we introduced in a previous lecture. Additionally, we'll examine this circuit's no/low voltage protection behavior when subjected to a loss and restoration of power and during overload conditions.
If you wish to replicate this experiment, here is the part list from automation direct:

it would have been great if you showed how the reversing kit is working in a bit more details like how it is wired showing the numbers of the contacts. the picture is not clear how it is set up. thanks for the video

[@johnptc]

nicely done :)

Can you explain why you are using both a manual starter (with a built in over load) and an additional overload? Wouldn't the Manual starter be enough?

[@bigbadtech]

Good question. You're correct, either one would serve to protect this system. You'll often see this type of arrangement for 2 reasons: 1) redundant backup in case one element fails 2) the manual motor starter could be servicing not one but several contactors, when a technician opens the manual motor starter everything downstream is de-energized. Elements not serviced by that manual motor starter remain unaffected. This serves as a means of functionally isolating certain elements of a larger system.

Can you make a video with 110 volt for 110 motor

[@bigbadtech]

Stay in touch. I plan to do a series on single phase AC motors (once I finish 3 phase AC motors). Often times 3 phase AC equipment is used to make and break connection to single phase AC motors such that all 3 contacts are wired in series with one another (ie: into L1, out of T1 into L2, out of T2 into L3, out of T3 to motor) such that three series switches simultaneously open and close.

Didn’t help that much
