Safety Controller
=================
The safety controller is the software component that monitors the overall condition of the reflow controller,
and stops the output driver in case of an error.
Severe error flags, like a drifting reference voltage, stop the PID controller and force the output to zero.
The controller stays in a usable state. After the errors have been cleared, normal operation may continue.
On the other hand, fatal errors like an over-temperature error, or memory problem, lead to the activation of the :ref:`safety_panic`,
which forces the output zero, but does not allow any further interaction.
