Topic tags/keywords: question planer

Just taken delivery of several new machines, pics and gloat at a later time once all installed :)
One of the machines is a 15” 3HP 220V Planer. Checking it over I noticed the rather short supply cable has blue, brown and black insulated conductors.

The manual, as would be expected of a generic machine, is, err, generic. The section on “Grounding”, the only reference to the wiring says “The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. DO NOT connect the equipment grounding conductor to a live terminal”

Ok, so I thought it could be a different standard to the standard standard, been googling and nothing so now wondering if it’s the chinese’ idea of a joke, seems to be the only colour combo that doesn’t exist in standards, apart from as 3 hot wires in a 3 phase installation Ground is green is ground as far as I am aware.
Is it possible the motor wants hot-hot neutral and blue is neutral? Seems unlikely as the manual, which is for a machine at least mechanically similar to the one supplied with it, specifically mentions the ground conductor.

Anyone got any ideas or do I have to wait till tomorrow to speak to the supplier, who I am sure will not know offhand and it will take a week or more of hounding them till they find out. Or maybe I will get impatient and pull the starter box/motor connections apart to work it out. I want to get a plug on this thing…

Who made the equipment? Does the manual have any tech support contact info? Who did you buy it from?

Thanks for asking at least :P Like I said, its basically generic asian manafactured import. I know, I know, but really the best I can do here. I am based in Mexico. I found the exact same manual online for a Steelcity planer. The local “brand” (importer) have just blanked out the Steelcity logo on the cover picture. Unfortunately as my planer comes with different coloured wires to those mentioned (well, only the green ground is mentioned but I definetly have no green wire:) that isn’t much use.

Here customer service is like this, you serve them by paying them some money, that’s where it ends. It is normal for salespeople to be just that, sales, no matter what they sell and they rarely have much knowlegde in their specific market area. I had to correct the suppliers on several items in the specsheets of these machines that I could see were obvious data input errors, I also located the chinese suppliers for a couple of them online and saw the same mistakes in their specs, so they had just been cut/pasted. In light of this I’m afraid n answer from them might take some time (the first one will be check the manual, but that won’t get us far..) anyway, I’m impatient, I got 3 new machines sitting here waiting tobe armed, not sure I’ll sleep tonight :)

Thinking about it motors often have black/blue/brown cables so it might just have got fitted the wrong side of the starter box, I think I will open it up and see if I can figure it, the ground should be obvious at least and the other two are both 110v phases so…

Call Armando, he will help you out. He was invaluable with me when I was dealing with Felder, which by Mexico’s low CS standards, they were the worst I have ever seen.

if you have multimeter, you can check each wire for continuity to the motor’s housing. the one with continuity should be the ground.

Sorted, I opened up the starter/switch assembly and I was right, they got their lengths of cable mixed up. The cord running from the switch to the motor is the red/blue/green+yellow that should be on the input side. The brown/black/blue should be feeding the motor. Black is ground :)
Off to level another table, thanks those who gave ideas..
