RX100 Series VDE Certified IEC60730 Self Test Code for RX100 Series
Today, as automatic electronic controls systems continue to expand into many diverse applications, the requirement of reliability and safety are becoming an ever increasing factor in system design.
For example, the introduction of the IEC60730 safety standard for household appliances requires manufactures to design automatic electronic controls that ensure safe and reliable operation of their products.
The IEC60730 standard covers all aspects of product design but Annex H is of key importance for design of Microcontroller based control systems. This provides three software classifications for automatic electronic controls.
1. Class A: Control functions, which are not intended to be relied upon for the safety of the equipment.Examples: Room thermostats, humidity controls, lighting controls, timers, and switches.
2. Class B: Control functions, which are intended to prevent unsafe operation of the controlled equipment. Examples: Thermal cut-offs and door locks for laundry equipment.
3. Class C: Control functions, which are intended to prevent special hazards Examples: Automatic burner controls and thermal cut-outs for closed.
Appliances such as washing machines, dishwashers, dryers, refrigerators, freezers, and Cookers / Stoves will tend to fall under the classification of Class B.
This Application Note provides guidelines of how to use flexible sample software routines to assist with compliance with IEC60730 class B safety standards. These routines have been certified by VDE Test and Certification Institute GmbH and a copy of the Test Certificate is available in the download package for this Application Note (See Note 1 below).
Although these routines were developed using IEC60730 compliance as a basis, they can be implemented in any system for self testing of Renesas MCUs.
The software routines provided are to be used after reset and also during the program execution. The end user has the flexibility of how to integrate these routines into their overall system design but this document and the accompanying sample code provide an example of how to do this.
