* @brief safety_controller_process_monitor_checks
* Process the analog and timing monitors and set the relevant flags in case of a monitor outside its limits.
* Furthermore, the PT1000 resistance is checked for overtemperature
*
* The checking of the analog monitors will only be armed after a startup delay of 1000 ms to allow the values to stabilize.
