Date and time recovery in case of a power failure
In case of a power failure, the system is able to recover the date and time information
from an internal real-time clock. A precondition however is that the active controller is of
the type CTL/3S, CTL/3T, CTL/4T or CTL/4S.
Power failures with a duration of up to 2 hours can be compensated with an accuracy of
the timing information after the recovery of ±1 second.
