Kiln Upgrade Help

Recommended Posts

I hope someone out there can help a newbie out with our old Olympic kiln. 

 

Info about it

Olympic Kiln model 2827

240V

Phase 1

60 amp service

 

I want to take off the old control box and connector boxes and install a new digital system that would eliminate the kiln sitter.  I also need new elements. 

 

I have talked to reps at Olympic and Clay King, but either I am not explaining my self well or their knowledge does not go as far as I need (I think it is that former) and I can't figure out what I need to order.

 

Can someone lead me in the right direction? 

 

Thanks,

Tess

The easiest thing to do is to simply purchase an external digital controller setup. The kiln  plugs into it, no rewiring necessary. The cheaper option is to build your own external digital controller setup, however if you aren't familiar with electrical systems it will be difficult. Basically you need a controller, a transformer to provide the proper power to the controller, either a 50 amp relay plus a smaller switching relay for single zone, or three 25/30 amp relays for 3 zone control, a Nema 6-50 receptacle, and an electrical enclosure to put it all in.

I'm considering building my own controller, my experience has been typically with skutt controllers, but I see the benefit in mounting that controller away from the kiln heat as well as its atmosphere. I have followed several of these forums about this subject, and have decided on the majority of my equipment, but I'm stumped on what kind of relay to use. It's three zones, so I know it's an 25 amp relay, but what brand, or price range, ect am I looking for. I understand this is probably a matter of preference, I could source it from skutt or l&l, but I've also seen relays from equipment wholesalers

You can use any of those. The L&L or Skutt items are comparable and will work without question.One sourced from an electrical equipment supplier will also work IF you select the proper one AND you properly read the circuit diagram shown on the side of the relay.

If you're doing a system with zone control, where each section of the kiln fires independently, then you can use a 25 or 30 amp relay for each section. You can get those relays from any of the kiln manufacturers. If you want to buy them elsewhere, you need a dual pole single throw normally open relay with a 12 volt coil (or whatever size coil is required by your controller-Bartlett controllers have 12 volt outputs). If you're doing a single zone system, then you will need to use a single 50 or 60 amp relay and that big relay should have a 240 volt coil, and you use one of the smaller 25/30 amp relays between it and the controller.

I was able to do this from the parts available from Euclids.com,   I made a kiln sitter Skutt 818 into a 2 zone Kiln.

Could the Schneider/Magnecraft relay 92S7D22D-12 be substituted for the TE/Potter-Brumfield T92P7D22-12? Because some of the Magnecrafts are available to me.

 

These relays would be used between the Bartlett V6-CF 700 Controller and the 240V Coil of the 60A Mercury Contactor/Relays. 

 

As far a I can tell, the specs of the two relays match (DPST-NO, 30A @ 277VAC, 12Vdc Coil).

 

More details available at: http://magnecraft.thomasnet.com/item/relays/relays-power/w92s7d22d-12 . Even more details available at: http://www.serelays.com/library/magnecraft-catalogs/8501CT1003.pdf at p23-25. For reference, the T92P7D22-12 specs are here: http://www.te.com/usa-en/product-6-1393211-9.html

 

Has anybody used the Magnecrafts? Any reliability or other issues? Anything else I should be concerned with?

 

Thanks for any input!

Neil, while looking at L&L kilns, I really like the Jupiter controllers, I noticed that one version has branch fusing, what's the benefits of having

 

On the higher amperage kilns the branch fusing is required by code. It's just another layer of protection. I think anything over 50 amps requires the branch fusing.

 

The Easy Fire control boxes are easier to work in, although the Jupiters aren't bad.

Has anyone wired a skutt computer controler to an Olympic kiln of similar style ie skutt1027-Olympic 2327

 

It would work just fine, like any other controller. The Skutt touchpad is larger than the Bartlett V6-CF and L&L Dynatrol, and is also dumbed-down a bit. The Skutt doesn't have as many firing options.
