MOTOROLA MVME259D Voltage monitoring card
The safety related parts of control systems must meet one or more of the requirements for five defined safety categories. The safety categories define the required behavior of safety related controller parts regarding their resistance to errors.Safety related parts must be designed so that individual errors do not cause the safety function to fail. Individual errors must be recognized the next time (or before) the safety function is required. If this type of recognition is not possible, a buildup of errors is not permitted to cause the safety function to fail.
Keeping a machine in an idle state
when people are working in the danger zone is one of the most important requirements for safe operation of machines. Starting refers to the transition of a machine or its parts from an idle state to moving state. Any start is unexpected if it is caused by: • A start command sent because of a controller failure or because of external influences on the controller. • A start command sent because of incorrect operation of a start element or another part of the machine. • Restoration of power supply after an interruption.
• External/internal influences on parts of the machine.
