Querying kiln performance

The controller can display the amount of energy required for a firing:
• The benefit for the user is that the power consumed is displayed at the end of the firing.
• The energy consumption can only be read if the value for the output of the heating zones has been entered in
the parameter configuration (parameter nos. 14/24/34 refer to section 12.).
• If the display shows the value "0.0" continuously, the energy consumption display must also be configured in the
parameter configuration (see Section 12.).
• The consumption values can be called up during or after the firing. When the controller is switched off, the
information is saved and remains available until a new firing program is started.
• During a firing, the energy used so far is shown. After a firing, the total energy used for the firing is shown.
• Information on the calculated amount of energy:
−
The controller calculates the amount of energy required by the kiln at intervals of 30 seconds
(factory-set).
−
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.
To check the required amount of energy (consumption values):
