3.3 Parameters of Leuze electronic protective devices for determining the PL in accordance with EN ISO 13849-1 and SIL in accordance with IEC 61508 / and SILCL in accordance with EN 62061.
For the products of the ASM1, ASM1E, COMPACTplus, ROTOSCAN RS4, SOLID, MSI-s(x), MSI-i(x), MSI-mi, MSI-mx und MSI-mix series, SIL in accordance with IEC 61508/SILCL in accordance with EN 622061 or PL in accordance with EN ISO 13849‑1 is specified in the technical data.
Help with selecting Leuze electronic protective devices
In the event that no regional or machine-specific specifications, such as European C-standards or OSHA /ANSI standards specify specific types of optoelectronic protective devices, the following selection aid can be used to select the appropriate Leuze electronic safety sensor for the risk minimization. The qualitative method presented in EN ISO 13849-1 is used for determining the required safety level. A risk assessment, e.g. in accordance with EN ISO 12100 and EN ISO 14121 must basically be performed beforehand and the notices in chapter Selecting and applying optoelectronic protective devices must be observed.
IEC TS 62046 recommends across the board under 5.3.2.2:
- With low risk: Type 2 AOPD and higher
- With medium risk: Type 3 AOPD (Safety Laser Scanners) or type 4 Safety Light Curtains
- With high risk: Type 4 AOPD
Risk parameters:
| S |
Seriousness of injury |
| S1 |
Minor (usually reversible) injury |
| S2 |
Serious (usually irreversible injury including death) |
| F |
Frequency and/or duration of the exposure to the hazard |
| F1 |
Seldom to not very frequent and/or exposure to hazard is brief |
| F2 |
Frequent to continuous and/or exposure to hazard is long |
| P |
Possibility of preventing the hazard or limiting the harm |
| P1 |
Possible under certain conditions |
| P2 |
Not really possible |

| Safety note |
| The selection of the appropriate type of protective devices for sufficient risk reduction is always the responsibility of the machine constructor or system integrator. No legal claims can be derived from the following selection aid. Regional laws or machine-specific specifications, reasons for product liability or the amount of the material damage can result in the selection of another type of protective device with higher safety-related capacity, contrary to the presented recommendation. If the possibility of serious, irreversible injuries exists, we recommend using an AOPD of at least type 3. |
