Hello,
As my username implies, I am way out of my comfort zone here, but here goes.
Have a Kuhlman steam sterilzer, just shy of 20 years old, that uses the aforementioned CPU(?), to further expand on the numbers, 216-2AF22-OXBO.
Daisy chained below this are four 222-1BF22-OXAQ modules.
The problem I have is it no longer properly reads atomospheric pressure, which when idle should be around 14.7. Instead it jumps all over the place, causing an issue whenever a cycle is started.
I did find a known good replacement for the 222-1BF22-OXAQ to eliminate that possibility, but after the vendor installed it, still no change. Vendor also checked things with a signal generator, all good there....pressure transducer that generates signal good, but replaced this to be sure, still no change.
This leaves just the main CPU, and according to him this is no longer serviceable.
That said, I see these used all over and am curious if ours can either be repaired, or if I can send ours in so a replacement can be sent back programmed just the way ours is currently.
Please dumb it down for me with any questions, etc. I'm in my comfort zone under the hood of a diesel engine, not in the cabinet of this machine. I know just enough to be dangerous.
Appreciate any directions folks, thank you
