Operation:
Step Description Remark
Activating the program
pause facility
The program pause facility is activated by
pressing the < key and then the f key.
The controller sounds a short beep, the
current program is paused and the
current kiln temperature is maintained.
Ending program pause
The program pause is ended by pressing
the < key and then the f key.
The paused firing program continues.
Indicated in the display:
Indicator on
the left
Main display Description Remark
PAUSED
While paused, the kiln
temperature display will
alternate periodically with a
scrolling “PAUSED” display
A repeated double beep will
be sounded.
Program execution is suspended, and
the kiln will be held at its current
temperature.
The pause will come to an end
automatically after a preset period.
The pause function is preset to 2 hours
at the factory.
8.2. Notes on the firing process
8.2.1. 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):
Main display Description
0 . 0 KWH
Press the < and h keys (a small “i” is shown next to this arrow key).
22°C
Press the h key again to display the current setpoint (the temperature that the
controller is currently trying to achieve).
