Figure 39: Typical TC Sensor Location
TC Sensor
The TC sensor’s appearance is exactly the same as that of the LEL sensor. Its housing
includes a sintered metal flame arrestor on one end that allows gas to diffuse into the
sensor. On the other end, five pins extend from the sensor. The TC sensor can be
distinguished from the LEL sensor by the part number imprinted on it. The TC sensor part
number is TE-7568 while the LEL part number is NC-6260B. The sensor cable connects
to pins on one end and terminates in a four-position connector on the other end which
plugs into the TC sub PCB (see description below). The sensor bracket is installed over
the TC sensor to keep it seated in place.
NOTE:
The LEL and TC sensors and sensor cables are identical in appearance. Take
care not to plug the LEL sensor cable into the port on the TC sub PCB and not
to plug the TC sensor cable into the LEL port on the main PCB.
TC Sub PCB
The TC sub PCB is a circuit board that is installed on the main PCB in one of the 3 sub
PCB positions when a TC sensor is used with the EAGLE 2. The TC sensor cable
connects to the sub PCB. The sub PCB plugs into the main PCB and is held in place with
a screw/flat washer/lock washer. There are no user serviceable parts on the TC sub PCB.
