Typical exhaust system on 50 Hz engines
(2) Thermocouple for the turbocharger outlet
(3) Thermocouple for the temperature of the left turbocharger inlet
(4) Thermocouple for the temperature of the right turbocharger inlet
(5) Thermocouples for the outlets of the cylinders The Integrated Temperature Sensing Module (ITSM) monitors thermocouples that measure the engine exhaust temperatures. The ITSM calculates the average exhaust temperature for each bank. The temperatures are broadcast over the Cat Data Link for use with other modules.Thermocouples measure the exhaust temperatures from the exhaust port of each cylinder. To observe the value of the output of the thermocouples, use Caterpillar Electronic Technician (ET) to view the "Cylinder #X Exhaust Port". The "X" is the number for the particular cylinder.A thermocouple is mounted at the inlet for the exhaust gas of the turbocharger turbine. Use Cat ET to view the "Left Bank Turbine Inlet Temp" or the "Right Bank Turbine Inlet Temp".A thermocouple is mounted at the outlet for the exhaust gas of each turbocharger turbine. To observe the value of the output of the thermocouples, use Cat ET to view the "Left Bank Turbine Outlet Temp".The following conditions can activate an alarm or a shutdown. The trip points can be programmed with Cat ET.
The temperature is higher than the limit that is programmed.
The temperature is lower than the limit that is programmed.
The temperature of a cylinder deviates significantly from the average temperature for all of the cylinders.
