Power3520 question
Anthony
>Took my new Powermatic 3520 home and in my basement shop(alone I may add)I've read the manual and it states not to touch the inverter keypad(which I haven't)My question is,what should be lit up on the LCD display when I plug it in and turn it on? Thanks!

>Yes, there should be a number in the LCD. That number will change with the RPM of the lathe. Some people encourage folks to unplug lathe when not in use because this box stays on, sort of like leaving your computer on. If I am going to be away for a long time, I do unplug but normally don't. Have fun with the beast!

>Anthony, just to keep in the back of your mind. I was using my bowl saver a little too aggressively apparently and the motor shut off. I noticed there was a reset switch on that keypad. I reset it and the lathe came back to life. That is the only time I have touched that keypad.
Since then, when I use my bowl saver I put the belt in the lower RPM range and haven't had the motor shut off again.

>Anthony,
As already mentioned, the display will show a number that represents "frequency" of the converter output. There should be a chart in your manual that allows you to convert this "frequency" number into RPM. There is a chart for the low belt setting and anothe for the hi setting. I HAVE pushed the button to change what is shown in the display but without a manual specific to the converter unit there is little meaning to the numbers.
Other posts have talked about removing power...I have ALWAYS unplugged the unit when it is not in use. It is an electronic unit and I think it is a good precaution. Recently I installed a disconnect switch in the line that feeds the 220 volt outlet for the lathe. It is a Square-D unit, about $14 at Lowes or HD. It has a lever handle on the side and a knife blade switch inside. The unit I got also has a place for screw-in fuses. I didn't really want the fusees but its all they had at the time. Now I just flip the lever to apply power. Saves wear&tear on the plug and outlet.

>I was told by a Powermatic technician that it doesn't matter a darn what buttons you push, as the console is locked anyway. According to him, unless you magically push the code to unlock the keypad, all it does it change the leds, nothing else.
Don't know, but thats what I've been told.
