8.3.3. Introduction of cooling air in cooling ramps
8.3.4. Memory
As soon as the controller is turned off, all programs and necessary data are saved and retained.
8.3.5. Adjusting the firing values during firing
During the program, certain firing values can be changed using the controller:
•
Use the
g
key to select the desired parameter during the firing process.
•
The parameter is indicated accordingly in the course of the program on the graphical display by a flashing icon.
• The firing value is shown on the main display and can be adjusted with the
d
and
f
keys in the usual way.
• The contents of the current segment or any segment still to be executed can be changed.
•
Firing will still carry on as normal while these changes are being made.
•
The controller will return to its normal running display 20 seconds after key presses cease (or immediately after
“END” is displayed).
•
Changes made to programs in this way are stored and are used for subsequent firings.

NOTE
The introduction of cooling air using a blower or fan at a firing chamber temperature of
more than 600°C can damage the insulating material or heating elements.
⇒
Cold air may only be brought in at a temperature below 600°C.
⇒ The fan cooling system must never run during the firing process!
⇒ The cooling system is only switched on below 600°C when the kiln is in cooling mode and
is not being heated anymore!
⇒ The exhaust air opening must be open when a cooling blower or cooling fan is in
operation.
⇒ Early cooling is not recommended as this can have a negative impact on the ceramics,
glazes and the durability of the kiln lining and the service life of the heating elements.
The manufacturer assumes no liability for damaged insulation material or heating elements if the
instructions have not been followed.
