3 functional safety
3.1 functional safety is what
Safety refers to the unacceptable risk of avoiding human health damage or personal injury, which is caused by any loss of property or the environment
The destruction caused directly or indirectly.
Functional safety is a part of overall safety and relies on the correct response of a system or device to its inputs.
For example, an overheat protection device with a thermal sensor on the motor windings that can be de-energized before the motor overheats is functionally safe
An example. However, the use of special insulation materials to withstand high temperatures is not an example of functional safety (though this is an example of safety and
