The exhaust gas temperature monitoring of the NOX monitor is used for monitoring catalytic converter operation and also as dew point detection for the NOX sensor (see section Dew Point Detection), and it is designed for thermocouples of type K. For up to two measuring points, you define a temperature threshold respectively, that must not be exceeded. If the exhaust gas temperature is to be monitored both before and after the catalytic converter, you can also define the permissible temperature difference range of the exhaust gas between the catalyst inlet and catalyst outlet.
You can configure the exhaust gas temperature monitoring in the NOX Setup view (see section Preferences).
