Chapter 7 Safe Limited Speed (SLS) Modes
This example assumes that a programmable safety controller is monitoring all
safety option functions and controlling the safety option. The SS_In and SLS_In
inputs are connected to the I/O module; however, standard safety component
inputs could also be used.
These functions are not performed by the safety option in this scenario:
• Guardlocking switch inputs
• Door locking
• Door status (open or closed)
• Enabling switch
