7.3 Learning the oven characteristics
Before the oven can be used for soldering, the controller has to learn its heat and tem-
perature characteristics.
This is necessary before first use and after every software update at least.
The learned values are stored in the controller and used for all subsequent soldering
processes. However, you can repeat the learn process as often as you wish.
The controller always uses the results of the most recent learn event.
The message “Error learn“ on the display indicates that the learn phase has to be run
and the controller is not yet ready for soldering.
When you see this message, start the learn process by pressing START.
You can also start the learn phase at a later time, as follows:
• Connect the oven and temperature sensor according to the instructions and switch on
the controller.
• After the self-test, please wait until the oven is heated to a just below 50 °C.
• Now press OK once and the message “Setup” will appear on the display. Press OK
again and press “Down” while the message “Setup” is still present (around 2 seconds).
“Learn” will now appear in the bottom line of the display. Press OK to start the learn
process. Please wait until the learn process is fully complete and do not interrupt it. The
controller is only ready to use when the learn process is complete and the oven is at just
below 50 °C.
• The learn process requires a board to be placed in the oven and the temperature sensor
positioned under or over the board in such a way that they make contact with each other.
This will ensure that the temperature sensor measures the board temperature and not
the air temperature.
• Close the oven and start the learn process as described above.
During the learn process, the “Learn” status is displayed, with information on each
phase of the process.
