Principles of Operation SET-TEMP LIMIT cuts off power to laboratory heaters to guard against thermal runaway when the temperature sensed by a thermo- couple exceeds the dial setting. Heating will not resume until the “RESET” key is pressed.
Then, should the liquid boil away, the sensing probe will still be effectively heated by the man- tle and SET-TEMP LIMIT will be able to turn off your heating mantle before any damage occurs. Connecting your Heater and...
C and degrees F. 3. Press the reset key to energize SET- TEMP LIMIT’s receptacle. Note that each time SET-TEMP LIMIT looses power or is turned off, the “RESET” key must be pressed to resume heating. Similarly, if the thermocouple disconnects or open-circuits, the thermocouple problem must be corrected.
