Setup of a safety function

Setup of a safety function
A safety chain normally comprises the following functions: sensing, evaluating and
responding. In detail this means:
• Detect = the detection of a safety requirement with corresponding sensors, e.g. SIRIUS
cable-operated switches or position switches
• Evaluate = the detection of a safety requirement and the reliable initiation of a reaction,
e.g. shutting down the enabling circuits
• React = shutting down the hazard through suitable motor switching devices such as
contactors, fail-safe motor starters, or fail-safe soft starters
