    Default Fog control

    I have a fog machine that works like any other (a hand held trigger you have to wait for it to get warmed up then press button when ready) I want to figure out how to run the fog machine from a channel off of my renardss 24.
    Is there a way to cut into the trigger box and run the renard channel to it so that when I turn the channel on its like pressing the button. I hope that made some sense.

    Has anyone done this, that could give me some advise?
    I will take pics of the fog machine trigger and post later today.

    i HAVE done this (i used an SSRez though)
    the principals are the same though.

    let me look for my notes on it.

    A relay contact would be my first try. Your REN SSR can turn on the relay.

    Can I not sequence the relay into my sequence? I was thinking set it off once every few minutes. I'm going to power the fog machine from a standard outlet. All I want the renard to power is the switch to let the fog out.

    Yes, you should be able to turn the SSR ON and OFF as per your sequence. The sequencer doesn't know what is on the other end of your SSR - a LED, lamp, relay, motor, etc.

    Use the SSR to run a mechanical relay. For the fog machine you need a pair of dry contacts. You are simply going to replace the button in the hand remote with the normally open side of a relay. You can do 2 things. You can run a relay with a 5v coil right off a SSR channel and make sure you add a "snubber" diode across your coil leads to prevent spikes back into your ssr. Or, just get a 120v coil relay and run it like you would any other 120v channel. Make sure you are setting the channel as On/Off and not trying to dim it (obviously). My suggestion is to just use the 120 volt mechanical relay. It is an easy way to give yourself dry contacts to do all sorts of things like power other low voltage systems like air solenoids, X10 components, or props from the halloween store with the little push buttons.

    Or
    http://www.radioshack.com/product/in...uctId=12477120 as a 5v coil

    If going the 5v route you need one of these:

    You add it across the coil leads of the relay. The white stripe of the diode should be on the positive side of the relay.

    Keep it simple. There is a small pump inside that runs off mains voltage. Just tap onto its lines. However you wont get the heat up delay so be consious of that.

    Now that's what I was hoping sombody would say. It's how I was planning to try anyhow. But today I found a fog machine timer thing at the Halloween store for 16 dollars. Don't have to cut anything or learn how to build an ssr or anything so for simplicity going to go that route. It sets the delay to activate and the duration time to spray the fog.

    I do thank everyone for their suggestions you guys never fail to help out!

    I am not sure how the little remote works but it may be simper than I thought. you might be able to just grab a standard IEC cable(if your's uses that for remote like mine does) and put a relay across it.i think it may be something like this

    1)ac voltage 2) pump and the light and switch are attached in parallel. so when you push switch you lower the resistance and trigger the pump.


    or the switch is attached so the normaly closed is attached to light and normaly open attached to light.


    Ether way crack it open. Relays can cost as little as a $2-5bucks, hell the timer might have one it it.
    Also try holding the switch down then you can probe out what pins the relay should be connected to.
