Remote off button on Nova DVR XP
Here's how I replicated the OFF button in a remote kill switch.
Materials: Doorbell wire Surface mount switch box Momentary contact push switch (works like a doorbell button) Magnet cover plate for switch box Grommet for switch box Tools Screwdriver fine tip soldering pencil (I like the butane powered ones for working around electronics) Needle nose pliers Procedu (Pictures on ABPW) TURN OFF LATHE AND UNPLUG IT. WAIT 5 MINUTES FOR THE CAPACITOR TO DISCHARGE. Loosen the four screws holding the controls panel. Pull outward and let it hang upside down. The ribbon wire from the control buttons come up between the electronic boards and connect via a blue connector to the upper board. Pull the blue connector off. I checked which two leads were connected by pushing the OFF button while checking with an ohmmeter. It was the two rightmost leads. Drill a small hole in what will be the left lower side of the control panel. Feed in doorbell wire, tie a knot in it for strain relief, leaving enough to reach the pins going into the blue connector. Strip 1/4 inch from the wires, bend into a "j" shape and tin with solder. Hook one j around the base of the first pin, crimp it tightly with the needle schnozzle pliers and solder it with the fine tip soldering pencil with just a dab of solder on the tip of the pencil. Repeat for the second pin. Make sure no solder or wire touches another pin. Replace the blue connector, replace the panel and tighten screws. Drill a hole in the end of the receptacle box for a grommet (not necessary if you use a plastic box). Attach a magnet to the bottom. I used a plain metal outlet cover and drilled a hole for the push button switch. The switch I used was a left over door switch for a hardwired alarm system. On top of the switch I epoxied a red painted knob. Insert the grommet in it's hole, feed through the wire, knot it for strain relief and attach wires to push switch. Assemble and test. When I tested mine, I turned the lathe power switch on and let it boot up. Then I pushed the OFF button (while the lathe was stopped) and got the burble sound. Then I pushed the red button and got the same sound. Sounded good so far. Then I pushed the on button and got a sound but the spindle did not turn. Instant panic. Then remembered I had left the spindle lock engaged. Tried again and it ran, pushed the remote button and it stopped. Notes: I will replace the doorbell wire with stranded wire like small lamp wire for flexibility and abrasion resistance, other than the portion soldered to the pins. These need to be single conductor. DISCLAIMER: Doing this may void the warranty. If the wires are not secure they may come loose and create havoc in the control panel. Don't blame me if your lathe explodes, your shop burns down, or your wife leaves you. However I am happy with my red button. Now for an electronic brake that slows it down when you push the red button.... -- Gerald Ross Cochran, GA Four is certainly an odd number of arms for a man to have. |

Gerald,

Thanks Gerald, I have a friend who has an XP so I'll be able to compare the
control panels...then get brave and forge ahead with a meter. "Gerald Ross" wrote in message ... John Wirth wrote: Gerald, Do you have any idea if the stop button wiring is the same on a DVR 3000?

Remote off button on Nova DVR XP
Are you THE John Wirth whose picture I see in a catalog?
To check the leads in the blue connector I had to make two pins to fit inside the openings. I started with some a little bigger and sanded them down on my 1 inch belt sander to the approximate size of the pins on the connector. Good luck with your tinkering. It would have been nice if Nova had put a jack on the control panel box attached to these leads. Then they could have sold an optional remote button which would just have plugged in.

You're reading my mind (again) Gerald.. last night I was thinking how bad I might screw things up if I made an adapter to plug in a duplicate control panel in... with 5 or 6 feet of wire and a magnet, even.. I would have paid for that option, for sure.. mac Please remove splinters before emailing |

Somewhere in amongst the messages on the MSN Nova Owners group site (http://groups.msn.com/NovaOwners/messages.msnw) there's a couple of posts from Walter Ahlgrim describing how he created a wired remote which had Start, Stop, Speed up and Speed down. There doesn't seem to be a decent search facility on the site so you may have to page through the messages until you find it. The circuit diagram can be seen in this folder - http://www.msnusers.com/NovaOwners/d...econtrols.msnw You probably need to join the group to see the messages I've created one myself which also has a remote stop daisy-chained off it. I made a post describing my remote here - http://www.ukworkshop.co.uk/forums/v...ic.php?t=18571 The numbers on the paper in the 2nd photo refer to the numbers in the original circuit diagram Hope this is of some use Duncan |
