Fig. 1-Drawing showing placement of thermocouple In exhaust duct.
RUN THE THERMOCOUPLE LEAD WIRE SEPARATE FROM ALL OTHER CABLES TO AVOID
INTERFERENCE TO THE T/C SIGNAL
The thermocouple wire is Iron constantan; the iron wire (red) connects to the negative terminal and the
constantan wire (white) connects to the positive terminal. If there Is any doubt about the identity of the
wires, the iron wire can be identified since its magnetic and the constan tan is not.
Install a Hauck Rapid Response Material Temperature Thermocouple in the material discharge chute to sense the
temperature of the material leaving the dryer. The thermocouple should be Installed as shown in figure 2.
Wire the thermocouples to the proper terminals in the panel.
