Greetings,



 



This is a (slightly) off topic but I am reaching out to the smartest guys I

know regarding this stuff.



 



I am FINALLY getting around to wiring up the switch you all helped me find a

couple of months ago on my 2 post car lift (it is in an airplane hangar so

it is legal to post on this forum).  



 



The car lift has an electric motor that drives a hydraulic pump.  The

Normally Open switch when pushed starts the motor and the hydraulic pump

moves the car up.  To lower the car there is a hydraulic pressure relief

valve meaning the motor/pump only operates one direction.



 



The black and white wires from my 2 pole circuit breaker panel and the green

bond wire are easy for me to figure out.



 



Inside the wiring box of the lift is a bit more complicated.  Attached is a

picture of the schematic label on the side of the wiring box and a picture

of the relay unit housed inside the box. 



 



Inside the wiring box there are the following wires:



-Green + yellow stripe wire that has a ground lug on the motor case and a

the other end is a loose end.



-Green wire that has a lug on one end and the other end enters the internals

of the relay box



-Blue wire that is loose on one end and the other end enters the internals

of the relay box.



-Brown wire that goes to the 5/L3 lug of the relay unit and the other end is

a loose end.



-Brown wire that has a lug on one end and the other end is a loose end



 



Can someone please help me "remember" what wires go to what on this

contraption???



 



I would GREATLY APPRECIATE your help on this!!!

Bill:

It is a lot easier with the units in front of me, but...

Here is a link that supports the colors you mention.

Oh, there are two standards in wiring motors:

1 - Wire Color Code - Which is not used very much and

2 - Wire Numbering - Much easier to understand.

This link shows the color code you are seeing:

https://www.doityourself.com/forum/electrical-ac-dc/396012-bodine-electric-motor-wiring.html



For a 220 AC Line:

T1 goes to L1

T4 & T5 go to L2

ALL the other wires get tied together and wire nutted and electrical tape wrapped.

I need better pictures or schematic of the relay.

But, Since as you say the Motor is ONLY powered and in one direction the relay is used to control that applied power as stated above.

Just tie the lines together through the relay so :

1 - A switch energizes the relay.

2 - L1 and L2 Go to each 110 V lines (110 + 110 = 220)

Hope this helps.

Hmmm...perhaps due to file size I should send them one at a time (sorry for

the spam)>

Here is a closer view of the relay itself.



Again...THANKS for your help on this (as always)!!!

Just an FYI Bill, I did have the pictures along with your first     message...using Thunderbird if that makes any difference.

     Same here, on both counts.
