Achievable Safety Levels of DS23x
To achieve a maximum of SIL3/PLe on system-level, no certificated sensors are required to fulfil the
integrity of the device. When using standard sensors, only the required safety level (by complying the
safety-related characteristics SFF, HFT, Type A/B, PFH, PFD resp. category, DCavg and MTTFd) and
systematic safety integrity must be ensured for the entire protection circuit. Software programs (like
SISTEMA) are very helpful for creating such evaluations of safety-related machine control systems
according to the EN ISO 13849 norm.

**** A safety level can only be achieved in these cases, if it is physically ensured that there only
can be only one direction of rotary and linear movement. This can be realized for example by
using a self-locking gearbox.
