I recently purchased a Jans 220V remote switch to use with my Shop Fox 2HP 220V dust collector.
Problem is, it won't start the DC. I checked the remote itself by plugging it into my tablesaw and it works as it should, however when I plug it back into the DC, no go.
The DC itself works properly when plugged directly into the outlet and powers on through its own switch.
I've checked polarity on all the wiring for the DC and everything is correct. The DC does not use a magnetic switch so that is ruled out.
When I use the switch on the DC, I can see the power light on the base unit flicker so I know it is working but the DC itself still does not respond.
I am by no means an electrician so here I am tapping the minds of many. Any ideas?
I waited for somebody that might actually know something to respond....that not having happened...I will venture a guess.
There might be a relay or something similar between the switch and the unit. Perhaps even a function on the circuit board. So if the power does not come through the switch, it won't energise the rest of the circuit.
I seem to recall that if you unplug my Jet unit while running and plug it back in it won't come on until you use the remote again. I could play with mine, but I am not sure that would help you with yours.
Not clear exactly what tests you performed but: did you unplug the DC, turn on its switch, then plug it in? If it starts then I have no clue but if it doesn't then there might be something besides a magnetic switch in the DC preventing it from starting, after a power failure for example. With modern electronics it such controls could be pretty subtle and small.
Brian, I would check a couple of things. First start your dust collector and while it is running unplug it, then plug it in again. If it starts and runs that verifies it does not have any hidden circuitry.
Second verify the rating of your remote as far as amperage. Your dust collector may exceed the remote's amperage rating and the remote unit may "kick out" due to overload.
Your table saw may not pull nearly as much starting current. If you have another piece of equipment with starting current higher then your saw try it there. Other wise I would contact the remote manufacturer and question them as to max load allowed.
It's possible the startup current of the dust collector is high enough that it cause the voltage to drop a bit at turn on. Causing the remote device to shut down.
What happens if you turn the remote on first, then plug the dust collector into it and then turn the DC switch on? Does it operate? If so, then that indicates a high startup current causing the remote to malfunction. If it shuts down, then the entire motor current of the collector is too high for that device and you would need something more capable.
