Topic tags/keywords: planer resource question

Hello I am currently a student participating in shop class and we have a powerpatic planer model 221 and the electrical switch box has been taken apart, only slightly, and I need a electrical diagram or a photo or something to go off of to properly re-wire the planer. the main plug-in has been taken off the input panel and has become a mystery as to how the thing goes back together along with the on and off switch. If Someone who has the same model planer (and hasn’t converted theirs to a newer style switch) could kindly snap a photo or even find a proper diagram I would greatly appreciate it. It is a mid 70’s planer and is belt driven to the cutter head, it was plugged in to 220 volts at one time and uses a furnas dual voltage coil switch for the on and off (I’m guessing) so hopefully someone can help me And my efforts to restore this beast of a planer back to its former glory. Thanks ( and yes I do realize what I wrote was a large run-on sentence).

Post a picture of what you got… there were a lot of different configurations and starters used over the years. Here is a generic starter wiring diagram:

Brad, Any idea what that 115 volt secondary transformer connection is for? Work light?

There’s 221 for sale on Cl in San Diego.
If that’s not the one your asking about maybe it will have your answers.
Gook luck looks like a Epic planer.

It’s a primary input, not a secondary… just kind of looks like that at first glance. Here is the actual transformer which has a better schematic diagram of it on top:

The first diagram, while looking funny, actually conforms to where the physical connections are on the transformer… which is probably why they drew it that way…. maybe :)

Brad

Thanks, I have never seen a diagram like that before.

This is what I have to work with, the old plug has been taken off and someone else has tried to re wire the thing and burnt the plug-in(yes it tripped the breaker and the main motors and switch box look fine), I need to know where the main power wires go because there are no clear markings and the inside looks like a complicated mess. Also I would like to check all the other wiring as well because there is no telling what else is wrong and why it hasn’t been used in years, let’s hope this is all i need to do. And I thank those of you who are a huge help.

Sorry, I can’t see enough in that picture to see where the wires go. I do Question why there appears to be a ground wire connected to the auxiliary holding contact terminal? It looks like the enclosure is too small to have a control transformer; therefore, the coil should be 220 volt. I do not remember for sure if Furnas coils have jumpers to change connections from 110 to 220 or not, but I believe they do.

The mains are at left in the photo, at top is the ground “green wire with yellow end. Then followed by the 3phase wires red. white and black.
From the photos, I cant determine the voltage its wired for.

Looking a little closer this AM. I do not recall ever seeing a Furnas starter in that configuration with the coil at the bottom. All the Furnas I remember had the coil behind the contacts. It looks like it is probably a 240/480 dual voltage coil connected 240. Nameplate is not quite in focus ;-( In any case, it is connected for the lowest of the dual voltage options. Furnas starters were always dual voltage coils as I recall.

It is a 240 volt, and it is a 240/480coil, the green block to the left has poles in the front you can see and more poles behind you can’t see witch go to the motors,and there are switch/relay on and off wires on the top right behind the top coil, the mains are what I’m mostly concerned about getting correct , and the green ground main seems like it needs to be grounded to the box itself because there are a cluster of other grounds together in the top left of the box, but I do believe the coils are supposed to be grounded for switching on and off. And if someone could explain how this mechanism works In lay mans terms I can troubleshoot it and trace the wires to where they go and hook the mains back up to their proper place I just want to make shure I know what I’m working with before I have at it, and not screw it up even more than what it is. And lastly should all of the same coded wires be together at least on this machine because some of the wires are not grouped and some are? Probably for motor rotation,maybe,or wired wrong. I’m thinking all wrong wiring.

The diagram above pretty well sums it up. That is where the wires need to go. Nothing is supposed to be grounded except the equipment ground on 240 volt control. Who knows why the wiring is grouped or coded. Obviously some one who didn’t have a clue has been playing electrician. That is a 3 phase motor starter. Just ignore the center pole. If the factory control circuit is still in place, it will be connected to the outside poles. Good luck.

Well I realize it’s been a while since I posted any progress on the old planer. initially I started to fix the switch box but the diagram and the planer wasn’t working together and the drum switch was ruined witch was one of the issues.so I decided to bypass the original box and mount a small breaker box on the side of the machine as my simple main switch and I used the old drum switch as the feed switch. I had to modify the drum switch to only work for forward and I used the planer like that without any problems and after a month then I put a 6 pole directional switch for the forward and reverse feed motor. I know that’s exactly the proper way to wire a Machine like that but it is double breakered, one dedicated breaker in the switch panel, and the breaker I have for turning the machine on and offand the directional toggle switch I have is rated for 380volts at 30 amps witch is overkill by far considering it is only fed 15 amps at 240volts. my logic says that is more than sufficient for it to work properly without any problems for the rest of the machines life. The only other problem I can think of is it has no overload protection for the motors other than tripping the breaker. Even though I didn’t use the diagram I still thank those of you who helped me and my efforts to finally restore this old planer to its former glory. and yes pictures and videos are on the way soon.

Have your say...
