So, for some reason my starter will not start my motor. The green button that pushes the switch that is supposed to start the motor just hums. The motor will run when I push the blue botton that is just to the left of the one that is supposed to start the engine. However, it will not stay in and keep the motor running

Motor is 5hp 230v 3 phase powered by a static converter

Anyone have any idea what I might be able to try? I tried reading the wiring diagram but it made absolutely no sense to me.

I would appreciate any info that might help me

Thanks

Tyson

I can post some pics tomorrow night. Hopefully the switch is still good otherwise I’ll need to get a replacement.

This is a shot with the cover off. Sorry for the sideways shot. I am not very good with photo sharing unfortunately.

Okay good picture,

Now WITH THE POWER OFF do the following

First press the red square button with the white “O” on it, gently at first and feel for a click reset feel, this is made of fairly delicate plastic. then press in the blue round button next to it, while feeling for a reset click.
The above procedure is confirming that the overload section is not “tripped” like as in a circuit breaker. Write down the setting of the large blue wheel to the left of the red square button this is very important! This setting must match exactly the amp rating of your saw motor. – Let me know if this works.

You may need to purchase a push button panel or a part for the mag starter, but not likely you will need to buy another whole starter. I’ll defer additional comment to a higher authority, the one about my post ;)

Ok…. I did not feel any reset click when I pushed each one separately. However, when I pushed the red one in and held it and then pushed the blue one in I did feel a very small click. Maybe nothig but I did feel something different As for the blue wheel, it was initially set slightly below 8. The value on it goes from 7-10. The plate on my saw says that it is a 3 phase 230/460 motor and has an amperage of 13/6.5. Since I rewired the junction box from 460 to 230 I should have a amp draw of 13 correct? The blue wheel will allow for turning past 10 some and stops at an “A” setting.

Could I have the wiring to the switch wrong? I have the wire coming from my static converter going to L1,L2, and L3. L3 being my white wire that is from my “B” leg on the converter. I believe this is the one that drops off line once the saw is up to speed.

Thanks again for all the help guys

I had those symptoms from an old 8” jointer – also powermatic, but not 3-phase. It seemed to work fine one day, the next it just hummed. I was told to try blowing the decades worth of dust out of the motor because it might be keeping one of the contacts from opening/closing. I used an air compressor and just kept blowing dirt out of every vent in the motor (unplugged) until there was no more cloud flying out and when I was done it ran like it was new back in 1952.

The saw is a 2000 model and was used pretty lighly in an industrial setting till last year. I will blow the motor out and hopefully get this thing going. Does anyone know if Telemecanique is still around and if there is a tech support number I might be able to call to trouble shoot this switch?

Thanks

I think Telemecanique was French. It was the first of the “international” standard motor starters that Ii remember seeing. It is fairly generic. They all work the same way. If the reset didn’t fix it, you need to determine if you are even generating 3 phases with the converter.

Where did exelectrrician go?

Topamax, Church first then a quick 4.6 mile hike and of course the big game on TV! – phew I’m baaak.

Yes that is a telemecanique starter – the small blue button has an adjustment you can make with a screwdriver.
Push slightly in and you can turn it left and right about a quater turn, fully left either auto reset or manual reset, could be the other way around though, a small white pointer will have A or M printed to indicate which mode you are in.
And yeah Topamax has it right, you need to make sure the 3 phase converter is working.

Exelectrician, I sent you a PM.

How Can I check if the converter is working? My motor wouldn’t start if it wasn’t working, right? I can make the saw run by pushing the big blue botton to the left of the push button that is supposed to be the start button. But have to hold it in to keep the saw running. I talked to the folks I bought the converter from and they told me it was working right because the light would go on and then go off.

I’ve got have the mind to just order a new switch. Could someone post a link to where i can purchase one that will work for this saw? I looked but really don’t know what I’m looking for. Just in case I can’t figure this thing out.

Thanks again for all the help!

I just reread your posts sawedoff. Assuming the converter is working as they say. Apparently you have never had this saw running yet, eh? This is a start up trouble shoot, not an it quit trouble shoot?

If it is the later, make sure coil in the starter is not 480 since you apparently rewired the saw from 480 to 240. If the coil is the correct voltage, try swapping the red and white on your incoming power.
