(3) Thermocouple for the exhaust outlet from the turbocharger turbine (4) Thermocouple for the exhaust inlet to the turbocharger turbineThe Integrated Temperature Sensing Module (ITSM) monitors thermocouples that monitor the engine's exhaust temperatures. The ITSM also calculates the average exhaust temperature for each bank. The temperatures are broadcast over data links 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 the 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 each turbocharger turbine. To observe the value of the output of the thermocouples, 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" or the "Right 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 of a cylinder deviates significantly from the average temperature for all of the cylinders.
