Questions and Answers
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 EN
TER
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 EN
TER
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.
