Caution! With increasing service life, the probability of component failure increases for every
technical product.
For operation according to IEC 61508-2, additional limit values are monitored (number of switching
cycles, operating time, number of switching cycles in the event of a short circuit). If the set limit va-
lues are exceeded, the device displays a prewarning or an alarm.
The alarm can be "deleted" by increasing the limit values.
To ensure continued operation in accordance with the IEC 61508-2 standard, the device must be re-
placed.
i
Regardless of the IEC 61508-2 standard, the safe function of the device is of course still guaranteed
due to the cyclical self-monitoring functions.
Operation in accordance with DIN VDE 0100-710, DIN VDE 0100-718 or IEC 60364-7-710 is still possi-
ble if the prescribed measures are implemented (see chapter „Periodic verification and service“ on p.
89).
