A.3.4
EMERGENCY STOP shutdown to SIL 3 or PL e with a 3SK1 safety relay
The 3RW51 soft starter has no effect or influence on the safety function of the application. For
this reason, it is neither positively nor negatively considered in the safety application, and also
does not have to be included in the calculation for proof according to the standards.
Safe shutdown up to SILCL 3 according to IEC 62061:2005 / PL e according to EN ISO
13849-1:2015 requires the use of 2 redundant contactors and monitoring of the auxiliary
contacts of both contactors. Two-channel monitoring of the EMERGENCY STOP is also required
here.
