How can I correct a value that’s been incorrectly typed before pressing ENTER?
Clear the display by pressing all zeros, then input the correct number and press ENTER. When a cone value has
been incorrectly entered the process is slightly different. After pressing 0000, press ENTER. The display will again
ask for a preheat value and then a cone value.
How can I change only one value for a RAMP/HOLD firing profile without re-entering the
whole program?
Follow tthe instructions for entering a new program and just press ENTER for every value that will remain the
same. Make a change in the value that is incorrect, then continue.
How can I change the program after it has already started?
Press the STOP key. This will stop the firing. Use either the CONE FIRE MODE or RAMP/HOLD MODE to input
the new firing profile for the remaining portion of the firing. Press START to resume the firing. The controller will
automatically determine where to start the program (based on the current internal temperature) and proceed with
the adjusted program.
The kiln shuts off too early.
The kiln can be restarted if the cones on the shelf indicate an under-fired load. (This should be used only if you
were present when the kiln fired off.) The cones are no longer accurate if they have cooled much from the time of
shut off. To restart follow these steps.
Press ● CONE FIRE or RAMP/HOLD to view the firing just completed.
Press ● ENTER to accept any of the segments that are correct until the point where the cone number or final
firing temperature is requested.
Program in a hotter cone or higher firing temperature. You could also add a few minutes of hold time at ●
the final firing temperature.
Press ● START after the reprogramming is complete. The kiln will begin firing based on current temperature
and will fire to completion using the newly programmed data.
Helpful hint ● If the firing is just slightly under fired, program five minutes of hold time at the final firing
temperature. This will allow the sections of the kiln that are somewhat cooler to catch up to the
hotter sections.
The kiln displays CPLt but the kiln won’t cool off .
Check the elements to see if any are still glowing inside the kiln. If a whole section of the kiln is glowing, a relay is
stuck. Unplug the kiln and contact your distributor for further information.
At night I see a blue flash coming out of the control box when it clicks. Is it serious?
The flash occurs when the contacts open causing a small arc. This is a normal occurrence and should not be a
concern.
I programmed a RAMP/HOLD profile and when I pressed Start, the alarm sounded.
Review the program to ensure that all segments of the profile have a value entered. Also, check the alarm to see
if a value has been entered that is lower than the room temperature. The default setting for no alarm to sound is
9999.
