Firing
To start a firing press the ► key. The firing indicator lamp will flash.
Hint: it is good practice to check that the program is correct by pressing the ►
key & checking the program number & program contents before pressing the
►
key to start a firing. It is also a good idea to have a written record of the contents
of the firing programs kept and displayed near the kiln especially if there is more
than one user of the kiln.
With the firing indicator flashing an optional
start delay up to 99 hours: 59 minutes can be
entered with the ▲ & ▼ keys.
Information: The KCR32C operates by calculating the amount of energy required by
the kiln every 30 seconds (this period is installer adjustable). If for example 40% of full
energy is required to maintain a particular ramp rate or a particular soak temperature
then the KCR32C will apply heating power to the kiln for 12 seconds every 30
seconds. The kiln heating indicator will light for 12 seconds every 30 seconds. If the
kiln has a contactor then a loud click will be heard both when the kiln heating indicator
lights up and when it goes out. If full heating power is required then the kiln heating
indicator will remain lit. If full cooling is required the kiln heating indicator will remain
After 5 seconds, or immediately if the ► key is pressed again, the firing will com-
mence and the firing indicator lamp will remain lit.
To stop the firing prematurely at any time press the ► key again. The firing indicator
lamp will go out.
Note: during ramping the KCR32C will perform either controlled heating or controlled
cooling
-
as indicated on the mimic display. During soaking the KCR32C display alter-
nates every 15 seconds between kiln temperature and soak period remaining. At the
end of each segment the segment number display will be incremented.
