A.2
Safety of electronic controllers
Introduction
The following remarks relate to fundamental criteria and apply irrespective of the type of
controller and the manufacturer.
Risk
A higher degree of safety standard applies to all applications and situations where there is a
risk of material damage or injury to persons if there is a failure. Special regulations specific to
the system apply to such applications. These must be taken into account for configuration of
the controller (e.g. VDE 0116 for furnaces).
For electronic controllers with safety responsibility, the measures required for preventing or
controlling faults depend on the hazard inherent in the plant. In this respect, the basic
measures listed above are no longer adequate once the hazard exceeds a certain potential.
Additional measures (e.g. double redundancy, tests, checksums, etc.) for the controller must
implemented and certified (DIN VDE 0801).
