Wiring issues...enco lathe
Hi all, Thanks for the massive knowledge base here. I'll be sure to help when I can but I need some help myself.
I have an Enco lathe Model:110-2032, MFG Date: 1992-1
I had to replace the belts and the motor starting capacitor. Once it was all back together I found issues.
Seem to be in the control circuit.
The drum switch does not turn motor on in either direction.
The emergency switch works properly.
When i press and hold either of the motor relay buttons it operates flawless.
Upon further investigation I found the relay does not click open and closed.
I checked DCV coming out of the bridge rectifier and it only gives 6.54.
The relay is an OMRON type F MY2...listed as 12v but says 24v on the coil inside...
I replaced the bridge rectifier with the exact same replacement part and I still only get 6.54 DCV.
If I jump the relay connectors the drum switch it still does not operate correctly.
I searched all over the web and can not find schematics, at least not for this specific model.
Any assistance would be greatly appreciated.
I have pictures and can post all details asked of.
Thanks again...

There is a large rectangular block with many contacts (8?), some would mistake for a relay. In a sense it is. It has a latching feature (why I asked you if you had used the momentary switch to activate the contactor). This block controls all of the circuits as it enters the machine. Hitting the E stop, interrupts the latch and stop all electric flow. It does have a mechanical test bar. Pics to follow.http://img.tapatalk.com/d/14/02/05/2ude7ehe.jpg

I'm posting in this thread again to help a fellow cnczone member. (Unless I can send pics via PM and I'm just not seeing the option.)
Paul, first I want to apologize.
I am the founder of a weapon manufacturing business so I'm always busy and dealing with everything all at once.
I was fast to reply at first because I thoroughly enjoy helping others but ultimately my plate is full and I keep asking for more.
Whenever you need assistance just post in here and I'll do what I can to help.
I have the equipment and can take pictures and trace wiring for you as well as answer component related questions.
However there may be subtle differences between our machines so I'll help where I can and other can fill in the blanks.
I had a difficult time finding any accurate schematics but luckily there are many on here that have acquired a strong general knowledge of electrical wiring.
Ultimately that's all you need to work on these older and simple machines in my opinion.
Once you learn which electrical parts do what, the wiring is mostly straight forward.
I strongly recommend research to acquire your own understanding because not only is it helpful for repairs but also for safety.
The pictures of the drum switch are at the end.
Here are a bunch of pics. Some useful, some probably not.

Thanks farshot83!!! Thank you for the time and the pics of the drum switch, it is identical to mine. Here is a pic of my electrical box if that will help others also. Attachment 232450 Also a pic of the drum switch off the lathe. Attachment 232448 Lastly a drawing of the switch and wiring. Attachment 232452 Thanks again for all your help and when I get the lathe up and running I'll post a couple pics. Have a GREAT one!!!
Re: Wiring issues...enco lathe
It looks exacly the same.
Ask if you have any wiring traces you need done.
Don't just wing it. You'll destroy it fast.
Change the belts while its apart if they show wear. Its not fun to do at all. A large hammer, mallet, large brass drift punch....etc. The main bearings and races should be inspected, cleaned, and tension set and checked after a brief no load run. Then checked again after a few decent test runs. Sure someone has more detail but if its not apart just check it over before you run it.
Much can be found out by feeling for play, slack, rattling and listening for whining and grinding. If you are even a little knowledgeable with machining then you'll know what to watch.
I didn't move you here for public thanks.
I am rather knowledgeable but not a single person knows everything.
I wanted to be sure you received the info you needed if I cant help or am wrong.
Also, no pics in PM's...
Dont be afraid to post on this forum just search first. Forums never tolerate redundance.
Many friendly helpful people here.
Re: Wiring issues...enco lathe
I am looking at everything to see if any worn or broken parts. With the switch wiring I can test contactors and caps with the motor not under drive power to the lathe. If all goes well it will be onto milling an apron case as when they dropped the lathe they major cracked the case in numerous locations. The drop bent one shaft and broke two handles. It was a good thing as a kid I got to work in an awesome automotive machine shop and learned how to straighten cranks back to zero lash and was able to straighten the shaft out. Onward with the project. Thanks

Re: Wiring issues...enco lathe
Farshot83, I forgot to ask what model Enco you have. It might work that other parts are inter-changable also. My Central Machinery (HF) was originally made by the Tida Machine Works in Taiwan and they rebadged a whole bunch according to my research. Here is a pic of my lathe after the drop and a little clean off.

Re: Wiring issues...enco lathe
Mine is
Enco 110-2032
MFG date of 1992-1
Its is an exact match.
Re: Wiring issues...enco lathe
Awesome, I should have noted, mine is a: Central Machinery TD-1236B, MFG date 1992 4, with serial # 5025. This might help someone else with the same machine but can't find any info on them if they do a search. Have a GREAT day!

Hi dadhelpme,
farshot83 actually is the one who owns an ENCO 110-2032, mine is the Central Machinery TD-1236B one. I understand they are the same lathe, just with different badge names. If you can look back to listing #28 at the bottom of the listing yu will see 3 pics I posted showing the inside of the control box, the drum switch for forward & reverse and the wiring diagram of the switch. Here is a pic of the motor wiring cover. Attachment 242854 All the pics can be enlarged to get a better view of location and direction. Also, here is a PDF manual of the CM lathe I have, it is sparse but does have some info. I hope this helps and if you have any more questions do not be afraid to ask. There are GREAT people on this forum like farshot83 that have helped me in the past.

Hi dadhelpme,
I am not sure if my post got to you as I do not see it when I log on, so here is another try with one more bit of info.

All the best in getting your lathe running and turning out chips!!!!
Re: Wiring issues...enco lathe
OOPS. For some reason, the links to the attachments posted in this topic didn't show up, at first. NOW, they do, so I was able to download the manuals. Thanks a bunch, guys!
