Hello
In our 9FA.03 machine from last few days TTXD_28 thermocouple is held on negative value (as like fault condition) and while it starts fluctuating, several times "FIRST FAILURE HIGH EXHAUST THERMOCOUPLE, L30TXAH1_ALM" OR "FIRST FAILURE LOW EXHAUST THERMOCOUPLE, L30TXAL1_ALM" alarms appears at MARK VIe and also others relevant alarms are appearing.
My question is: Can anybody tell me, how HIGH and LOW exhaust thermocouple failure is detected? what is logic? I noticed while fluctuation is started never it goes to higher than highest thermocouple value. So how it is detected that "1st failure of high exhaust thermocouple"?
