Thanks for the video but the diagram at 1 minute 57 seconds should have been explained a bit better as I struggled to understand until I went and googled. I think the signal coming from the PLC to 95, then 96 to contactors coil should have been clearer as I now understand the 96 is going to A1 of the coil. But another line is coming from the coil straight to the PLC which which I now conclude is going to the PLC's MINUS from A2. Thanks for the video!!

@Renegade Flower, Thanks for the comment. The polarity is all dependent on if you are using, sinking or sourcing, inputs or outputs, on your PLC. That is why polarity was not mentioned in the video, hoping to reduce the confusion. Best laid plans and all. I will look into adding a comment, to the video, to reflect this. Thanks again, for helping us improve our information.

In what situations would you want an overload to automatically reset itself?

@automationdirect 6 лет назад

@Skimtar, thanks for the comment. I rarely use an automatic reset on an overload. I do so only when the scenario will not cause damage to machine or personnel. One scenario I remember was the motor being undersized for the conveyor, and it would cause momentary overloads, stopping the process. The instantaneous trip of the overload would catch each time. So, I applied the automatic reset, but I did this, knowing that upstream fusing would catch if there was a real overload.

@Mr.Oblivian 4 года назад

So an overload protector kind of turns it into similar to a breaker?

@automationdirect 4 года назад

Yep, a breaker that protects your system ...

How calculate Tripping current???

@automationdirect 6 лет назад

Mohit Nama, this comes down to knowing the load, you are placing on the contactor. For example, If you have a motor with a FLA (Full Load Amps) of 8A, you might set your tripping current at 8A. This should be sufficient for most applications, but if your motor is taking a high inrush at startup or under load, the current can exceed the FLA. In these situations, it is typical to add 10% to 20%, to accommodate for this inrush. The best way to measure, would be to use an ammeter and determine your max current draw then add 10% to 20% on top of that. Thanks

Are you reading from the code book ? What is this 28 stuff and why aren't you specifying 430.52

@automationdirect 3 года назад

Not sure I understand the question ... the 430.31 referred to in this video is the Motor Overload and Failure to start section of the code. Section 430.52 is for ground fault which is not the subject of this video.

@crosslolo7245 3 года назад

@@automationdirect why though..as an electrician we're always reading from the code book. So my question is wouldn't it be more conducive reading from code or at least specify your references?

@automationdirect 3 года назад

@@crosslolo7245 Thanks for the suggestion. This video is intended to be a high level overview for the casual learner. So we were trying to avoid getting bogged down with lots of code references. Hopefully folks that know the code wouldn't need a video like this! Regardless, we will take your suggestion to heart and make it a point to at last mention the direct references in the future - thanks!

@@automationdirect no worries maybe consider youtubr directs viewers to all types. When your in depth you may just want to consider inserting code along with that.But that fine ill look for other teachers since yours are for I guess apprentice..
