The diagram and flow chart show that the kiln control system, in its simplest form, works like
your thermostat at home – when the temperature is too cool the heater comes on; when the
temperature is too hot the heater turns off. The major components of the control system are the
Genesis controller, thermocouple temperature sensor, relay switch, power source, and heating
elements. The controller is the brain of the operation; the controller adjusts the traveling set point
according to your program, reads the temperature in the kiln, cycles the relay on or off and determines
when to end the program.
The thermocouple (T/C) sensor is the first part to inspect when loading the kiln. The tip of the
T/C should protrude approximately 1- 1/2” into the firing chamber. Next, “START” is pressed, the
controller reads the kiln temperature and uses that temperature as a starting point for a traveling set-
point (also called the local set point). The displayed temperature is the temperature inside the kiln. You
should then hear the relay(s) start cycling on and off to keep the temperature near the traveling set
point. As the firing progresses the controller moves the traveling set-point according to the programmed
firing rate. The displayed temperature should increase with the traveling set-point and the relay will be
“on” longer. This sequence continues until the final temperature is reached and the controller turns off
the kiln. The display reads “COMPLETE”.
Adjustments During a Firing
Once a firing has been started, the screen will change to the Firing Screen, as seen on page 6.
You can still view the program and make adjustments to the firing.
Stop
Press STOP at any point in the firing to immediately stop the firing. The controller will
return to the Home Screen. To start the program again, simply restart the kiln. The controller
will start in the segment with an up-ramp equal to the kilns current temperature. If the kiln does
not restart in the segment it was stopped in, press the Adjust button and skip to the desired
segment.
View (Applies to Novice Mode)
View the setting for the firing. For a ceramic firing, the preheat time, cone #, speed, and
hold time will be displayed. Press the “Graph” button to view the firing as a graph. This includes
time, temperature, and segments. To see each individual segment, press the “TABLE” button.
