I’ve been looking for a long time at automating my blast gates for DC. I’ve been using the key fob start for many years. I’ve got it attached to my tool belt. I want to fire the tool and have it turn on the DC and then open the blast gate. when the tool goes off, it shuts the gate. My challenge is doing it with the variety of tools. I’ve got 20A & 30A single phase 240, and 20A 3 phase 240, and a 15A single phase 120V. I’ve looked at building something both pneumatic and electric with selenoids and building a voltage sensing coil and adrino processor, and they all got very expensive quick. I’m thinking now about www.grngate.com system. It seems really like a doable solution. I’ve also looked at the ivacpro system. they can support the 3 phasse no issue. I like the self cleaning of the grngate.

Anybody out there come up with something better or cheaper. The setup to do what I need is going to run 400+

Check out the Ivac pro system. It works wirelessly with single and three phase tools up to 10hp.

Www.ivacswitch.com

First rate products from a first rate company. I use the Ivac switch and it’s first rate.

Just consider: the cycling of the DC motor might increase significantly if you adopt that type of start/stop. That, in turn, may shorten the life of the motor considerably. Not trying to talk you out of it, just give it some thought.

Thanks for the replies. I’ve looked at the ivac, and seems well made and can handle the 3 phase. That’s the 2nd option I’m looking at. They also have a nice feature that one gate will remain open so you won’t get into a state where all the gates are open and the dc is running. As to the cycling of the motor, they have a delay that is programable so I can’t see it adding too much more on/off’s than already experienced with my wireless remote keyfob solution I use today. The DC has been a good one. I bought it new in 1990, and its still going today.

Ok I made the decision today. I spoke with one of the owners at Grngate and very interesting guy, we talked and I like the philosophy of what he’s doing the off the shelf cables and the ease of installation and use. I’ve ordered a 6 gates. I got the 4 gate starter set with sensors and a two gate set with manual switches. Interesting concept to supply power he’s using power over ethernet great idea so no little transformers. Off the shelf components in the cables make it nice.

I’ll have the main control unit for my 2hp collector, automatic controls for 18” planer, SawStop TS, 17” Bandsaw, 12” Jointer. I’ll have another gate for the kapex chop saw, and one last one for a catch all gate for use with the router table, and sweep.

Once I get it installed I’ll do a detail review. I’ve been wanting this set up for a long time, and this is the cheapest way I’ve found to get it without creating the sensor circuit myself. Delivered cost is 121/gate now more gates would be cheaper, but not bad. We shall see!
