8.2.3. Recovery in the event of a power failure
 In the event of a power failure during the firing, the controller can automatically continue the firing after the power
failure.
 In the event of a power failure during the program delay, the start is delayed by the remaining program delay
when the mains voltage returns.
 In the event of a power failure during the ramping, the controller continues the ramp it had been executing.
 In the event of a power failure during the soak period, the controller goes to the soak temperature at the set
ramp rate and then carries out the remaining soak period.
8.3. Operating notes
8.3.1. 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.
8.3.2. 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.
8.3.3. 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
 The exhaust air opening must be open when a cooling blower or cooling fan is in
 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.
8.3.4. Memory
As soon as the controller is turned off, all programs and necessary data are saved and retained.
