SC2 overshooting

awrylemming · December 01, 2011, 08:20:57 PM

I've just ramped up my kiln on the usual garaging program (as advised on the FH thread) and for the first time ever it has overshot temperature. It hit 594 then shouted at me. How rude! Soooooooooo, should I be worried? Do I put it back on now, or leave it until I've spoken to somebody. Faff with the program. Sacrifice a couple of my children to the kiln gods?

Does it go up at full? I think there was a thingy saying you can set the ramp to a highish but non-FULL number instead to help prevent overshooting.

It does, but never had any problem before .... should I give that a go d'ja think?

ETA Actually I've just checked it and have it on the second schedule ramping up at 700. So it shouldn't be overshooting, I don't think. Dammit, I can't afford for the kiln to be unwell right now!

I've had that happen to me too when it was ramping too fast ..... let us know how you get on x

What happened with yours in the long run Trudi? I've restarted the program and this time it was fine, until I finished my session and skipped a segment. Then it ramped up very quickly and overshot again before readjusting itself. This doesn't usually happen, so I'm a little concerned.

If I go 'full' mine overshoots so I ramp slightly less than full and not had a problem so far. But then in fairness, I now put it on overnight and rarely sit and watch it.

When I reduced the ramp speed it was better.

Thinking back a few weeks .... I had trouble with the kiln suddenly loosing heat during a session - I replaced the relay and it's been fine!!

You can get a relay from http://www.penninecomponents.co.uk/
1 x T92 Series, Flange Mounted, 30A, DP N/O
(4952343)
GBP 6.60 + GBP 1.32 VAT (20%)

P&P was a bit more but delivery was very quick. Might be worth a try if you're still having problems. If you do go that route - PM me and I cab forward in instructions showing you how to replace it!

Good luck x

Thanks Trudi
I'll keep an eye on it over the next few days, although I'm wondering if it's worth having one in stock just in case ...

Trudi · December 02, 2011, 09:11:53 PM

Wouldn't hurt!

awrylemming · December 03, 2011, 01:18:26 AM

Well, part all ordered and ready to go, so hopefully, if it's needed I'll be able to sort the kiln on Monday

Thanks Trudi

No problem, do you need me to send the info advising how to change it?

awrylemming · December 03, 2011, 08:26:14 AM

Would you mind? Even if I don't need to use it immediately, it's worth printing off and keeping with the part. Unless it should be posted as a sticky for others in the same predicament, possibly?

firedinglass · December 03, 2011, 08:32:45 AM

yes please do post it for all of us SC2 users to have for info just in case! I think i will also order the relay. I find things usually go wrong on bank holidays or just when i really need them!!!!! Hope you manage to sort out your problem with the kiln Sue.

Thanks hun - I haven't ramped up since, as I had a lot on at my daughters school, but we're now done with the fair (apart from clearing up), so hopefully I'll have time to play now.
