Behaviour of the temperature controller
In order to be able to assess the behaviour of the temperature controller, you will find examples of the statuses of
the voltage supply and the resulting statuses of the controller in the table. The table represents a chronological
sequence.

The alarm is acknowledged, i. e.
the error is cleared, and reset is
completed. The controller sets the
SA bit to “0”.
The sealing process is possible.
