Saw wiring problem

[kitchenman]

I need to rewire my 240 volt ELU TGS saw, I made a diagram when I took it apart but now it wont work.:doh

Does anyone know how the wiring should look?

My main problem is I do not know how the capacitor is wired to the motor, it is in series with the mains supply or in parallel.

This all came about after a 'specialist' rewired it after the old no volt switch died. The saw is so old spares are not available.

So he mounted the no volt switch on the side near the start stop switch, after I had been using it for a few years I needed to add the extension table, the no volt switch was in the way. 'Specialist' is no longer there.

So I am stuck without my saw HELP.

If any of you guys could send me a sketch of how the wiring should look I will be able to figure it out.

I think the problem is with the capacitor, wired wrong, I do not want to fiddle blindly.

The sketch does not need to include the no volt switch, mains in to the motor with wiring to capacitor showing will do.

The no volt switch can be refitted as soon as I get the motor running :bow:bow

have you tried contacting ELU or one of their dealers for help?

how many wires have you got coming out of the motor itself and what colours are they or do you have numbers and letters on the terminals, any chance of a pic, Rick

 

[ssteve]

just googled "elu tgs saw" the is loads to trawl through

not sure what you rewired but

I looked at both of those and more but could find nothing that applies, Rick

 

[zippy656]

ah right, ok,

will get back to searching...

Kitchenman, if you type "motors with start capacitor" into google you will get a diagram of a capacitor start motor with centrifugal switch if you do not have the switch you will have a "start" winding instead, around 70 uf on the capacitor for the switch type, around 25 uf for the start winding type, Rick

Kitchenman, I have the exact same saw and a proper no volt switch assy if you want:thumbs
I can take mine appart and check the wires for you when I get home later

 

[kitchenman]

Thanks for getting back guys, the problem is not the no volt switch it is the idiot:doh with the screwdriver who messed up the wiring.

I have a mate who is a electrical maintainance spert, said he will pop round sat & sort it out

Hi
ELU was taken ovr by DeWalt who in most cases carried on with elu kit as is
Find their equiverlent saw and the wiring may well be the same
My elu sds hammer drill and 18 volt drill are the same as dewalts with interchangable batteries and parts.

found a diagram

Found this via Google

Saw still not well:doh

Thanks to all of you who tried to help:bow:bow

how many wires do you have from the motor itself, Rick

 

[kitchenman]

motor wires

Hi Rick, there are 4 wires at the motor, earth green/yellow, blue,brown & black.

At the no volt I have :-
Blue to neutral
Black to capacitor, other side of capacitor to live
Brown to live

There is a connector strip on the motor picking up the blue, brown & black

There are smaller wires from this connector strip that actually go inside the motor casing. Cant help with the colours right now [colour blind] but will take a picture by lunchtime & post it.

I will also make a sketch of the relay wiring, I am OK with those colours, I am red/green colour blind. I know from others there is no red or green, except yellow/green [earth]

I have a diagram for the later model, mine is a TGS 172 the diagram is TGS 173, there are many differences, the capacitor is on the motor on 173 & frame on 172. If it will give you a clue i will scan it.

motor connection pics

This is the picture of the connections motor end.

I hope the colours are clear enough 3=black, 2=blue & 1=brown, OK but I do not have a clue as to the colours of the thin wires, but the go to spade connections below the numbers.

These thin wires then go into a two sleeves which then go into the motor picture follows

 

[kitchenman]

close up, I hope this helps.

If I disconnect the capacitor the motor will not start unless I give it a twist, it then seems to run at the same speed as before. It will go either way at a similar speed. With the capacitor in circuit it always starts the same way.
There is around 150 volts between black & blue & 235 between brown & blue

I took off the belt in order to get at the connections

 

[kitchenman]

cracked it I think

Hi Guys, I think I have got it sorted, wont know for sure till I get a new belt for the saw.
Motor starts well now with a bit of a jolt like it used to:thumbs
It seems to be capacitor feed to the motor was swapped with neutral.
I traced the wires carefully after Rick asked which wires went to the motor.
Drew a sketch & then found the capacitor was going to the common on the windings, switched them at the motor & all seems well

Voltage at both capacitor & live at the motor indicate over 300 now was 155 & 235. The low reading at the capacitor terminal would have been because power was going through both windings to get to neutral

Thanks to all of you who gave your input & Rick for pointing me in the right direction:clap:clap:bow:bow:bow

See easy when you know how, Rick
