2.4.2 Temperature Probe Connections

The TMP100 temperature probe connections are made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the four screws at the corners of the unit detaching the splash guard from the unit. On the bottom of the splash guard, you will find a label detailing the wire connection to pin number assignments, which are repeated in the table below.

Exhaust Gas Temperature Probe 0 (positive terminal) Exhaust Gas Temperature Probe 0 (negative terminal) Exhaust Gas Temperature Probe 1 (positive terminal) Exhaust Gas Temperature Probe 1 (negative terminal) Temperature Probe 2 (positive terminal)

Temperature Probe 2 (negative terminal) Temperature Probe 3 (positive terminal) Temperature Probe 3 (negative terminal) Temperature Probe 4 (positive terminal) Temperature Probe 4 (negative terminal) Temperature Probe 5 (positive terminal) Temperature Probe 5 (negative terminal)

Before attempting to connect the TMP100 to the temperature probes, determine the type of system you will be monitoring. The TMP100 supports the connection and monitoring of two different system types; 1) Exhaust Gas Temperature probes (Section 2.4.2.1), or 2) thermistor type probes (ring/under bolt probes, immersion probes, and ambient air probes; please see Section 2.4.2.2).
