Snow Machine help??

Recommended Posts

Hi, I am new to the hardware side of things here. Last year we purchased our first 16 channel kit. While my husband handled the unit itself, setting it up, etc. I was in charge of sequences. Worked well, until I decided I want to add another 16, and a snow machine.
My question is:
Can I just use an empty channel on my system to plug in my snow machine? The snow machine will be set to 'always on' and in theory will just 'blow snow' when that channel is turned on.

Thanks for any insight.

You do not want to directly control anything that has a motor with LOR. You could control a relay with LOR and then use the relay to turn the snow machine on and off.

I'll second that you do not want to put a motor on the LOR controller directly. The use of a relay is highly recommended. But also keep this in mind. You can kill the Triac that is used as the output of the controller if you connect anything that is inductive such as the coil of a relay or solenoid like a valve. What you want to do is buy a MOV that is rated for either 130VAC or 150VAC. A coil when the power is removed generates a spike. The MOV will on purpose become a short when voltages exceed its rating. So the spike will cause the MOV to short circuit and kill the spike before it kills the Triac.

In a nutshell, install the MOV across the coil of the relay and then wire this to the output of the controller. Then run a hot lead to one of the contacts of the relay and then out of the other N.O. contact to the snow machine. Also run a nuetral out to the snow machine. Remember only ON and OFF commands to that output. And you should be GTG.

Good morning

I utilize x10 control module and appliance outlets

to control my lasers

This is only on - off command and lasers have their own programs

- Just as a note - I added a string of minis to each laser

to provide an electrical load to the appliance outlet - lasers electronics

would not turn on without a small electrical load present

The cm11a control module is a rs232 device. If your show computer does not

have a rs232 port, an usb to rs232 convertor is required I use radio shack

Attached is the x10 equipment I utilize.

I just read my post and realized that I did not

mention that a x10 component(cm11a)

can be controlled from LOR's sequence editor

The cm11a will use another port on the computer

either rs232 or usb

Good evening

That is actually where I bought my equipment from

Did not have my documents with me earlier so I just found

a source on the net

Bought a spare cm11a 6 weeks ago because they are discontinued

and I have not heard about LOR doing an update to include --is it a cm15a

So, Evan,
the X10 system somehow replace needing a MOV and a relay?
Thanks, Ron

P.S. I loved you're daytime halloween walk through!

OK, I admit it...I'm stupid .. I've read the above posts, but am still way way lost. Can someone draw me a map in English? :P
I'm using the MP3 director so I guess I'm going to have to go with a relay / MOV setup to work the snow machines that I bought. What's an MOV? for that matter, what (exactly) do I need to buy? And how do I wire it up from the LOR controller to the snow machine. It's all greek to me.

THANKS
(hangs head in shame)

I figured it was a surge suppressor of some sort (via google) but it's the wiring that I don't understand (the relay part) I did install a relay in a sprinkler system on the lake pump but I just had to unsolder and then re-solder it into place the same way. Should I use a solid state relay...SPST or DPDT...

Here you go, a good read. http://en.wikipedia.org/wiki/Surge_protector

The MOV is installed across the relay coil or if you can find a way that works better for you, across the terminals at the LOR controller.

Does this help?



Yes, that helps,
I did not understand why when you answered this question correctly, the thread went to X10?
I thought maybe X10 acted as a relay or a MOV. but now I'm back on track.
Thanks again for your patients

Ron
