Heating of workpieces to a set temperature; the temperature of the workpiece is monitored during
the whole process.
In this mode, a gradient is also entered with which the heating process may take place. In
the settings menu, it is possible to select a double measurement / ΔT measurement here. T1
(temperature sensor 1) is the main sensor here and is the master for the heating process.
For example: Heat the workpiece to 120°C with a gradient of 5°C/min.
After switching on the process, the heater controls the power output so the heating curve for the
workpiece follows the gradient set.
During heating, a white dotted line is shown in the chart, indicating the ideal curve for the heating
process. The actual curve will be slightly above this line, since the controller first has to find a
balance between temperature increase and the matching power output.
NOTE!
This mode functions well only if the gradient set is realistic in relation to the maximum power that
the heater can output and input into the workpiece.
The gradient can be set in X°C/min.
In this mode, one or more temperature sensors have to be used that are positioned on the
workpiece to be heated.
9.2 Heating in temperature mode
•
Position the workpiece and sensor (according to chapters 7 & 8.)
•
Switch on the heater and select the temperature mode if necessary.
