Wiring for the Exhaust Temperature Module
Wiring for the Power Supply
The range for the input voltage is 10 to 32 VDC. A 12 volt supply or a 24 volt supply can be used.
Illustration 1 g01473696
Connections for the CAN data linkIn petroleum or industrial applications, the exhaust temperature module communicates with the advisor monitor display over the SAE J1939 CAN data link. In these applications, the CAN data link must be connected to the exhaust temperature module at pins 5, 8, and 9. Refer to Illustration 1.

Channels that are Connected to Thermocouples
Note: All of the wiring for the thermocouples must be type K.The exhaust temperature module has a channel for each thermocouple. For example, channel 1 represents the number 1 cylinder. The wiring from each thermocouple is connected to the terminals for the corresponding channel. Channels 21 through 24 are used for the thermocouples for turbochargers.The cable for the thermocouples has a pair of wires inside the insulation: one of the wires is yellow and one of the wires is red. The yellow wire is the positive wire for a thermocouple. the red wire is the negative wire for the thermocouple. The polarity of the wires must be maintained or the readings will be incorrect. Table 1 lists the connections for thermocouples for various engines. Table 2 lists a description for the remaining pins on the 70-pin connector.
