Remote control for a dust extractor?

[justinpeer]

Recently picked up a dust extractor that will live outside my workshop. I’d thought to use a smart switch to turn it on and off but it has an NVR switch so that won’t work as it won’t turn back on after it’s been turned off by the smart switch.

Any suggestions on how to add a remote control other than just removing that switch and fitting it with a regular one?

What is a NVR switch, is the same as the red and green magnetic switch on lathes etc

Yes exactly that, it’s called a no voltage release switch. If power is killed to the machine, the switch cuts and it won’t restart when the power is resumed, prevents a machine starting automatically after a power interruption.

Instead of removing the NVR, put the remote switch after it.

Switch is built into the machine so would require some rewiring.

I’m not averse to that but I was wondering if there was a simpler, non-destructive, way as I see plenty of YouTube videos where people have a remote fob for their dust collector and just wondered how they might be set up.

....YouTube videos where people have a remote fob for their dust collector and just wondered how they might be set up....

These videos don't have NVR switches or they have been replaced or bypassed.

I use this one on mine:

Edit:
Sorry, I answered too quickly on my phone and I was not thinking straight. My dust extractor doesn’t have a NVR switch so I don’t know what would be the effect. I can test it on my planner later and confirm the effect. Apologies.

Edit 2:
I have now tested on my planer and confirmed I was wrong: it didn’t work with the NVR switch so. Apologies again.

Looks like the only thing is to re-wire that switch then. Thanks.

Maybe this helps

I removed the NVR switch and replaced it with a toggle switch and then used a commercial remote socket. I had to add a jumper wire to the toggle switch. The good thing is I can easily convert back to the NVR if I wanted to sell the extractor.

Maybe I'm missing something but, if this is a permanent arrangement, why not just extend the wiring so the NVR switch is inside the workshop. Or is it that you want to be able to turn it on and off from a fob?

Note that most of the remotes default to off when they lose power anyway (only a very few have the 'memory' to revert back to their previous state) so they are effectively acting as a NVR anyway...

Easy to test- turn it on with the remote, and then turn it off at the outlet- wait until it spins down (never healthy to restart a motor while is spinning) and then turn the power back on- if it kicks into life, its not acting as a NVR, if it stays off and you have to push the remote to et it to start up again, then it is acting as an NVR...

Most won't start back up- as that means you have the possibility of a load (light or whatever) coming back on after a blackout- plus it requires extra components added to the 'guts' of the remotes receiver to be able to 'remember' the state it was in previously- and that makes it more expensive- for something 99.9999% of people will never even see in use once...

Quite a few people run 'ducted' systems with gates and a single extractor- thats where the remote comes in handy- either just clip it to your belt, or have one at each machine (you can get 'learning remotes for a couple of bucks lol) where you want to be able to turn the extractor on/off from multiple locations.. (some also fit- either in addition to, or in place of) a 'master/slave' arrangement- where turning on any machine automatically turns on the 'slave' power outlet (with the extractor in it)- some get quite complicated- with multiple electrically controlled gates added in with the current sensing auto on master setup-it can get pretty complicated lol...

One example of susch a system can be seen at 'Metal and Wood Shop's' Utube channel (been on my subscription list for years lol) which shows parts of his system with the electric gates etc
(should start at the right spot about halfway in where he's showing the gates for the extraction system...)

Looks like just the thing, thank you very much.

That’s an option I was looking at but a remote would be useful as I could have one at each machine. Mostly I was asking to see what other people used as I figured this would have come up before.

Not worried about that really, more I was looking for options to control from inside the workshop with the dust collector outside.

Was just mentioning that almost all of them will work as a NVR anyway for those that panic about it 'not having one anymore' lol

Ah understood, thank you.

Many run the extractor itself away from the shop due to the noise (in fact the video I showed before has his mounted upstairs well away from his shop lol) but his is a 'full on' system, with electrically controlled gates on multiple machines etc- he's added to it gradually over the years until its now fully automated... he started off with homemade manual slide gates and walking back and forth to turn it on, now the whole lot is fully automatic- starting any machine opens its gate and turns on the extractor... (I suspect like me- his age is starting to tell, and things like that make life a whole lot easier lol)

 

[justinpeer]

I’ll take a look at the video in a little while, sounds very useful. My shop is fairly small and, to start with, the dust collector will be for the lathe and bandsaw but I may extend it round to the mitre saw, still deciding if a dust collector or a shop vac with cyclone is the better option for that.
