Safety Function
Specification
Value
High-demand
mode
The EUC (Equipment Under Control) is considered as a high-demand or continuous demand
mode system.
Mission Time
The mission time of the EUC is of 20 years.
Diagnostic
Time Interval
In order to guarantee the correct operation of the safety functions, the user has to check the
STO function regularly, performing an STO External Diagnostic Test (see further information
below).
The diagnostic test interval is defined as a minimum of 1 activation per 3 months.
