Querying kiln performance

• The controller operates by calculating the amount of energy required by the kiln every 30 seconds (installer adjustable).
• The benefit for the user is that the power consumed is displayed at the end of the firing.
• Before the controller can display the required amount of energy in kilowatts, parameter no. 14 (see Section 10.) must
be set with the kiln performance.
• The consumption values can only be called up during firing or at the end of the firing curve. If the controller is switched
off or a new program is started, the consumption values are deleted.
• To check the required amount of energy in kilowatts (consumption values):
h
Press the key (a small "i" is shown next to this arrow key).
• If for example 40% of full energy is required to maintain a particular ramp rate or a particular soak temperature then the
controller 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 off.
