2.2.2

Determination of the required performance level (PL

)

The PL

is determined in combination with the safety function within the framework of the

higher-level risk assessment. For each safety function, the required PL

is estimated using

the risk graph below.

Figure 2-2

Risk graph (in accordance with EN 13849-1)

Meaning of individual parameters:

2.2.3

Technical implementation

This step involves the technical pre-planning of the safety function, taking possible technol-

ogies and components into account. The safety-related components and parts must then

be identified for later verification.

Dividing the safety function into subsystems

In the next step, a safety-related block diagram must be created for further evaluation. As a

rule, a safety function consists of sensor - logic - actuator. In the simplest case, each one is

a subsystem. These subsystems are connected in series to form the overall safety function.

S: Severity of injury

Slight (normally reversible) injury

Serious (normally irreversible) injury

F: Frequency and duration of exposure to the hazard

Seldom to not very frequent or exposure to hazard is brief

Frequent to continuous or exposure to hazard is long

P: Possibility of avoiding or limiting damage

Possible under specific conditions

Scarcely possible

Low risk

High risk
