When the Controller is first turned on
The controller runs a brief self-diagnostic test. The display will light up and the audible alarm should beep. After a
few seconds, the display will alternate between the kiln temperature and IDLE. IDLE is the mode where the
controller is not actively firing the kiln or being programmed for a firing.
Starting a Firing
The display shows -ON- for 5 seconds when the firing begins.
The display will show kiln temperature throughout the firing. The temperature display will alternate with
alarm messages if any alarms occur. If the controller is programmed to hold at a specific temperature, the
remaining Hold Time will alternate with the temperature during the active hold period.
Stopping a Firing
When the controller completes the firing, the display alternates 4 messages: CPLT (Firing Complete); Firing
Time (hrs.mins); Final Firing Temperature and Current Kiln Temperature. Press any key to return to IDLE.
If you stop the firing before completion with the Stop key, the display will indicate ABRT (abort) in place of
CPLT. Press Stop again to return to IDLE
Programming values
Whenever a change is made from the keys, you must press the Program/Start key to load the changes. If the
key is not pressed, the controller will simply wait for your next selection. Pressing the Program/Start key will
advance you to the next option if you are setting up a program or changing settings.
Note: If you are programming the controller options and no keys are pressed for 90 seconds, the controller will
exit the options menu automatically.
Program Review
To review the current program in the controller memory before or during a firing, press the Decrease/Review
key. The entire program will automatically scroll through the display and then return to normal operation.
Delay time is included in the review.
Repeating a firing
If power is not cycled off to the controller, you can repeat a firing without viewing the entire program, simply press
the Decrease/review key when the controller display is showing the desired program group. The controller will
scroll through the program review and advance directly to the Start prompt. Press the Program/Start key to set a
delay time and again to begin the firing.
Program Sets
The controller contains several sets of preset programs. Each set can be turned on or off depending on the user
preferences. To disable a program set, see the configuration appendix of this manual.
When first powered on, the controller will show IDLE, to view the program sets, press the Program/Start key.
Then press the Increase/Option key to see all available program sets.
Note: some program sets may be disabled or turned off by the kiln manufacturer or supplier depending on the
application.
Program sets include: SPD (Speed) – JWL (Jewelry) – CLAY (PMC) – CONE (Ceramics) – USER (custom)
