Harry Alonso Posted December 4, 2012 Report Share Posted December 4, 2012 Hi everyone: We have a 350-35-TRA22 with a EX-1 and a IO-ATC8. The problem start when the system was restarted after last year, the thermocouple card was reading unusual temperatures then after that is start reading 0 in all the chanels. I change the thermocouple card with any advance, change the ex-1 and the cable with the same result; I put one of the thermocoules on the OPLC an I get the expected temperature (room temp. at this time), put back the thermocouple at the card still get 0, (card is configured for thermocouples). Any help will be graetly apreciated I run out of ideas. Quote Link to comment Share on other sites More sharing options...
