AS-i 3.0 EtherNet/IP Gateway with integrated Safety Monitor

6.1 Checking for safe turn-off
The safety representative is responsible for checking flawless function of the AS-i
Safety Monitor within the safety system.
Safe turn-off when an associated safe sensor or switch is triggered must be
checked at least once a year.
Attention!
To do this, actuate each safe AS-i slave and observe the switching behavior of
the output circuits of the AS-i Safety Monitor.
Attention!
Note the maximum turn-on duration and the overall turn-on operating duration.
These values depend on the PFD value selected (see section <Safety-relevant
characteristic data>).
When the maximum turn-on duration is reached (three, six or twelve months),
check the complete safety system and its proper function.
When the total operating time (20 years) has been reached, the device must be
returned to the manufacturer to check for proper function.
