IDEC SmartRelay Manual 19
These measures are referred to as basic measures.
Carrying out tests
You must, however, ensure safety in your plant.
Before finally commissioning a sy
stem, carry
out complete
functional testing as well as all the necessary safety testing.
In testing, also include any predictable fa
ults that can occur.
This means that you will avoid any danger to the plant or to
people during operation.
Risks
In all cases where the occurrence
of failures can result in
material damage or injury to persons, special measures
must be taken to enhance the safety of the installation – and
therefore also of the situation. System-specific and special
regulations exist for such applications. They must be
observed on installing the control system (for example, VDE
0116 for burner control systems).
For electronic control equipment with a safety func
tion, the
measures that have to be taken to prevent or rectify faults
are based on the risks involved in the installation. Beyond a
certain degree of hazard the basic measures mentioned
above are not sufficient. Additional measures must be
implemented and approved for the controller.
Important information
The instructions in the operating manual must be followed
exactly. In
corr
ect handling can render measures intended to
prevent dangerous faults ineffective, or generate additional
sources of danger.
