Resurrection of a CFEI 100 KVA Induction Furnace
awemawson:
Thanks Pete but I've not given up with it yet - I have other bits of software to unleash on it still !
So - what happens if I put a bit of steel in the crucible and 'ping' it again? Theoretically the frequency should be lowered - but is it ?
. . . . YES :clap: :clap:
(This just confirms that it IS actually measuring the frequency and not just throwing up random numbers !)
Sea.dog:
Fantastic news Andrew. In my book when a fault lamp is illuminated it indicates a fault. Have you determined what the three sensors do? (I see that originally it was two, but they've been scratched out and a third drawn in)
awemawson:
Graham, yes I agree on for fault, but the picture of it 'ready' back in 2006 had the phase rotation light 'on' - in fact I have proved today that it has to be 'off' in fact so not sure what was going on then ! (*)
The various sensors all seem to be thermostatic one on things like the water source, internal big coil, the tuning capacitors etc.
The simple link in the other chain is something to do with the key switch that switches between the ping mode and normal heating.
More investigation needed tomorrow - at the moment I'm mentally exhausted :bugeye:
(* Later Edit :No it doesn't - only the first picture from 2005 while it is initialising shows the phase rotation fault indicator 'on' . I must have swapped phases for the other pictures !)
hermetic:
Excellent news Andrew, I have complete faith in you! On the chiller, lots of food industry factories use brine tanks for fast freezing, also ice cream and chilled desert makers, have you any contacts within aforesaid industry that might be able to link you to a chiller unit! You have probably already considered this, but just in case......Good luck! I can smell hot metal even this far north!

Thanks for the thoughts and suggestions Phil,
Matthew - I have emailed you the searchable .PDF scan of the manual and also a picture of the machine plate as you suggested. The file is pretty big at 8 Mb so I hope that your eMail server doesn't bounce it.
