► Adhere to the principle of normally closed operation for all external safety 

circuits connected to the system�

 

► In case of faults within the fail-safe sensor which result in the defined safe 

state: take measures to maintain the safe state when the complete control 

system continues to be operated�

 

► Replace damaged units�
