There was a specific date code range on the TEC's that needed a capicitor installed at the End of line (I think it was that or the last TEC...can't remember) I will look it up and post the specifics of the date code range and the Cap value.
Had a job with about 35 TEC's and they would go On-Line/Off-line about every 90 seconds or the Temp would go Fault/Stale at -1. deg for a minute or 2 then come back to normal. The capacitor and the latest jar files fixed it. The Cap helped alot but the jar file stopped the nucsance alarms in addition.
I think it was a.047 microFarad capacitor ?
If sense were so common everyone would have it !
