Care to share the love with a couple of feet?

Awesome! Those standoffs were going to cost quite a bit, I am glad I can dump them. They can always be added back later.

I am going to use these spark plug boots:

And protect the cable and boots with these:

Wow. You guys just saved this project like $500+. I though I was going to have to use local enclosures for each burner and all sorts of conduit. Not anymore!!!

I'm having trouble with my BCS/8610 setup. I can not get the BCS to reliably control the igniter's. I have spent way too much time diagnosing this. And have pestered CodeRage to the point he probably never wants to hear from me again. Hope not! He has been great help.

Anyway I think we have the trouble narrowed down to an RF issue interfering with the BCS when the igniter is sparking. I can get things to work if I move the BCS out of the enclosure that I have built for my stand. But the stand is built and I really don't want to move the BCS. Is there anyway to shield the BCS from the RF?

I mention this here looking for advice, but also for others that design with the 8610's. Be aware of the issue. It has been very hard to diagnose. If I only had a spectrum analyzer, or whatever to find RF.

Try .01uF-.1uF capacitors from outputs/inputs on the BCS unit to brewstand frame to shunt the RF harmonics from the spark coil and leads. Another step would be to loop wires to BCS through ferrite sleeves to also reduce RF influence on inputs.

Thanks Kevin. I have tried this,



May be hard to see. I have a Resister and a cap wired between the 24V gnd and TH-W terminals on the 8610. This "seemed" like it helped, but not totally fixed the issue. BTW CodeRage suggested this to me. I do not have enough electrical knowledge to figure that out. But tell me what to do and I do OK.

Do you have a different idea?

Would a tin box around the 8610 help to hold the RF in? I'd use galvanized sheet, or I also have copper sheet that could be used.

A quick test would be to tape a cover of aluminum foil over ignition module leaving enough space around spark lead to prevent arc and ground it to the frame. The other thing that can be done is to make sure that the ground wire between module and pilot is secure and at least 16 Ga.. Try placing a .1uF capacitor across the 24V Gnd and THW connections without a resistor in series and across the 5V and Gnd connection on the BCS-460 to help limit the RF interference problems. The next step would be to install same size capacitor between outputs and Gnd and the same for the inputs to bleed RF pickup to ground.

Reason: added capacitor information

Ron,

If the aluminum foil suggestion that Kevin made works, you can build a nice neat little Fadaday enclosure to go around the spark modure out of double sided PC board. You can get copper tape so you can solder the enclosure electrically tight and just ground the enclosure to earth ground.

Hi,

Just got this on Ebay
http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT

I still haven't got
24 VAC transformer (would 50 hz will be good as well?)
temperature controller

what else would I need to control my HLT ?

Just the 24 volt transformer and a Q345A pilot burner.

Thanks for the response, few more questions

I'm using LPG, would this pilot burner still be good?

What's the purpose of the pilot burner ? Is it a must or could I manage without it (to save the extra cost)?
