APPENDIX E: HIGH TEMPERATURE LIMIT
Two high temperature limit instruments (P/N 402731) are provided for temperature indication
and over-temperature protection. Each instrument receives a thermocouple input and provides
a 0 to 5Vdc temperature signal to the PLC. The thermocouple of the MATERIAL CONTROL
instrument is positioned to read the temperature of the material as it exits the dryer while the
STACK TEMPERATURE instrument’s thermocouple senses the temperature of the exhaust
gases. The alarm contact of the STACK TEMPERATURE instrument is used to shut down the
burner if the preset high temperature limit is exceeded.

Upper Display: Normally displays process temperature. Also displays parameter values or
selections when in the set up mode.
Lower Display: Shows value of set point. Also displays function groups and parameters when
in the set up mode.
