Operating the enabling button 
The enabling mechanism comprises one integrated enabling button with three settings.  
The signals of the enabling button are evaluated internally and sent to the connection box 
over the connecting cable. For setup mode, these signals must be wired dual-channel from 
the connection box to the F-system or configured via PROFIsafe. 
 
For a hardwired F-system: When a SIRIUS safety relay is used, the enabling button meets 
the requirements of Safety Category 3 in accordance with EN ISO 13849-1. 
●  The HMI device is connected to a correctly installed connection box. 
●  For a PROFIsafe-based F-system only: A project for PROFIsafe communication has 
started.
