the value corresponding to the dial setting, the
thermostat switch opens. This turns off the heating
indicator light and causes the contactors to open,
stopping the power to the heaters.
As soon as the thermostat senses that the kettle is
cooling below the set point, the thermostat switch
closes, the heating indicator light comes on, the
contactors close, and the heaters come on again. On-
off cycling continues, keeping the kettle at the set
temperature. This is why the heating indicator light
cycles on and off during normal operation. Every time
the kettle is tilted, the tilt cut-off switch interrupts the
power supply to the heaters, so that the heating
elements will not operate while not submerged in the
jacket water.
If steam pressure greater than 50 PSIG is generated
in the jacket, the safety valve will open and relieve the
excess pressure.
If the jacket water level gets too low before the
heating elements overheat, the high-limit control will
open and shut off power to the elements until the
kettle cools.
Setting the operating thermostat dial to “OFF” shuts
down all control and heating circuits.
