    Love this right now! walking into my motor controls midterm and hasnt been explained in this way so have felt very stressed. we've been wiring up starters on a wooden project board with the power being a power cord, and visually it is not very helpful trying to relate it to how it might look in the field, and the teacher has us wiring them up after we do homework assignments out of the book, instead of walking us through the testing techniques or how to wire them/just expecting us to know everything from the book, and it has been very difficult for me, a visual learner. Ive luckily been wiring them correctly, but this helps visualize everything so much better and makes me feel very confident. thank you so much for this video. the ladder diagram videos are helping me alot as well; i understood how they worked, but also not very confident on drawing my own and your videos are helping me so much!! thank you thank you.

    On question Pete. In what line number you connect the high voltage wire when you are
    installing 3 phase motors. I have 2 wires at 120 v each and another of 200 volts.
    Thanks in advance for your answer. Thanks for the instructive video.

    Hi! I have logic written to control the coil on and off on the motor starter according to level setpoint. The logic can latch the circuit, so do I need the holding contacts anymore on motor starter??

    Hi! Quick question do you have to use a holding contact with the coil? I have logic written in a program that no longer needs a holding contact on motor starter using a set/reset block in function block.

    • @PeteVree
      @PeteVree  3 роки тому

      This video does not incorporate a PLC. The holding contact is required to maintain current to the contactor coil.

      @@PeteVree I have currently a motor starter that was wired 3 wire control without logic… now I am adding a plc for control of the motor starter… I can wire it as a 2 wire starter now. There is no start button, just a selector switch from off to auto. It’s becoming a fun project and appreciate your help!

    Hello Pete, I really appreciate these video. I notice that you have a smooth "drumlike" attachment on the shaft of your motors. Is that a belt pulley or some training device that you install so as to prevent snagging of clothing?

    • @PeteVree
      @PeteVree  4 роки тому

      I believe our tech, Sam, had some aluminum machined to connect to the motors. Back in the day we used to used wooden clamps on these units so that we could simulate an increase in loading on the motor.

    The control circuit in blue coming off L1 is fused to 1 amp. The 208 coil draws less then that. I’m installing a NEMA 1 thats fused with a 3 phase disconnect. Can I add this to my starter bucket. This circuit will be wired in on a pilot relay to a low voltage controller.

    what does the 18 stand for in front of L1 label on contactor ?

    • @PeteVree
      @PeteVree  7 років тому

      Hi Michael, it actually says 1 & L1... meaning that that terminal corresponds to L1, but will also be used as the supply conductor for your controls, in which case it would be numbered as wire #1 on your control diagram. The 2 3 to the left then corresponds to the normally open holding contact, which would then have wires #2 and #3 on either side of the contact.

    when you have to take mesuring the coil, you have to disconnect wire on it

    • @PeteVree
      @PeteVree  8 років тому

      In our shop the wires simply go to terminal blocks on the left hand side of the starter enclosure, so there is nothing connected to the coil at the moment I am taking the resistance reading.

    • @martinreneb1
      @martinreneb1 8 років тому

      In a real troubleshooting situation, the coil may be powered by the 24 v, so it is the 24 volt coil that can be read if the wires are not removed. I sincerely believe that it is preferable, to show a sure method to measure a coil for student.

    • @PeteVree
      @PeteVree  8 років тому +1

      OK. Noted. Out in the field, please remove the wires from the coil so that you make sure that you are only reading the ohmic value of the coil.
      But again, in this video, the disconnect is in the OFF position, which means that there is NO power to any of the components, and nothing is connected to the terminal blocks.

  • @dogwalker666

    The mcb is more accurate as fuses are so old school more expensive and a pain to change, also overloads are disappearing to most people uses something like a gv2 combined isolator circuit breaker and overload. In the UK panels should have finger protection on all live terminals that way you can work in a live panel with no chance of accidentally touching lives.
