Operating notes

6.9.1.

Kiln too slow

• If the control unit is programmed to heat the kiln at a faster rate than the kiln is capable of then the control unit will turn
on full power and then wait until the kiln temperature has risen to the correct temperature before proceeding to the
next ramp or soak segment.
• If the control unit is programmed to cool the kiln at a faster rate than the kiln is capable of then the control unit will
apply zero power and then wait until the kiln temperature has cooled to the correct temperature before proceeding to
the next ramp or soak segment. That is, as soon as the kiln has reached the desired temperature.
6.9.2. Heating & cooling ramps
• The control unit is capable of controlled ramps for both heating and cooling.
• The type of ramp required is determined by comparing the required soak temperature to the soak temperature in the
previous segment. The ramp is then shown during the firing on the graphical display.
• With a normal cooling ramp, the cooling is not "active (fan cooling system)" but natural. With natural cooling, the heat
lost by the kiln is compensated for by targeted heating so that it only cools down very slowly. This technique is usually
only used in glass fusing.

Introduction of cooling air in cooling ramps

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
⇒ 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,
The manufacturer assumes no liability for damaged insulation material or heating elements if the
instructions have not been followed.

Memory

All programs & necessary data are remembered when the controller is turned off.
6.9.5.

Adjusting the firing values during firing

During the program, certain firing values can be changed using the controller:
g
•
Use the 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
• 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.
