10.2.3 Mission time

The mission time of the used component must be observed and complied with. When the

mission time of a component has expired, the component must be taken out of service and

replaced. Continued operation is not permitted!

The specified mission time starts at the date of manufacture. The date of manufacture is

permanently stored in the component and can be read out via an object.

For the STO safety function of the i700 device series, no special examination is specified.

Therefore, the mission time cannot be reset via an examination.

The proof test interval is the period after which a proof test to reveal undetected faults

must be performed.

The proof test is a periodic examination to reveal hidden hazardous failures in a

safety−related system so that − if necessary − a repair can bring the system back to an "as

new" state or restore it as close as under practical considerations possible to this state

(see DIN EN 61508−4).
