*Information:
The MS1E41-024 is an expansion module with no internal diagnostics. To attain Cat 4, PL e according to EN
ISO 13849-1, the MS1E41-024 must be used with a Cat 4, PL e master module and the NC feedback output of
MS1E41-024 (contacts 51-52) must be connected in series with the start signal of the master module (as shown
in sections 10.2.2 and 10.2.3). This must be done to prevent any start/restart of the system if an internal
failure in the MS1E41-024 has occurred.
