4. Programming
The
Magma
preheating oven gives you the option of
creating and saving heating programmes.
You can store up to 99 different heating programmes
(P01 to P99).
A heating programme comprises a maximum of 4
heating stages.
Each heating stage consists of the following heating
phases:
- Increase phase:
Heating rates in the range between 0 - 9 °C/min.
(0 - 17 °F/min.) can be specified. An input of “0”
is interpreted as the maximum heating rate.
If an increase phase is used for cooling in
a programme (the holding temperature of
the subsequent stage is lower than that of
the previous stage), the controller sets the
rate to 0 °C/min. (0 °F/min.). Cooling always
takes place at maximum speed which is
determined by the oven’s heat loss.
- Holding phase:
You can also enter the holding temperature and
holding time (max. 3 hr.). If no holding tempera-
ture is entered (0 °C / 0 °F), the programme
skips over this heating stage.
4.1 Programme Selection
You can store up to 99 different heating programmes.
To select a specific heating programme:
1. Press the “P” key.
2. Press the lower +/- key until the desired pro-
gramme number is displayed.
4.2 Entering Heating Phase
Values
1. Use the cursor keys to select the heating phase:
/
2. Modify the desired value(s):
- Increase phase:
Enter the heating rate in °C/min (°F/min).
- Holding phase:
Enter the holding temperature in °C (°F) and the
holding time in hours:minutes (max. 3 hr.).
Holding down the +/- key will change the value in
larger increments.
As soon as you modify a value the pro-
gramme LED goes on to indicate that val-
ues have been modified and can be saved.
3. Permanently save values and remain in the input
mode:
(Briefly press the ENTER key.)
This will save any value you have modified in this
heating programme and you will remain in the input
mode.
A successful save is indicated by a brief acoustic
signal and by the programme LED simultaneously
going out.
Follow this process (steps 1 - 3) to enter the values
for all desired heating phases.
4. Exit the input mode.
Immediately start the heating pro-
gramme.
OR
Display the current casting time start-
ing point.
You can program a new, later casting time starting
point (refer to Sec. 5.2.2) and then start the heating
programme.
OR
Return to the normal display.
If there are still any unsaved values, this will be
indicated by the programme LED going on.
Press the ENTER key to save these values now.
OR
Cancel the input and exit the input
mode.
All modifications not yet saved with the ENTER
key are deleted and the original values are reset.
In addition, the controller exits the input mode and
returns you to the normal display.
If you press the ENTER key for a longer
period (2 sec.), previous values you entered
for this programme will not be saved. In-
stead, you will be taken to the “Copy pro-
gramme” mode (refer to Sec. 4.3).
