RMS705B generates a fault message with regard to date and time in the following
cases:
P
ossible cases
If the clock on the bus is missing and the local clock is parameterized as time-of-
day slave, operation continues on the internal clock and fault message "System
time failure" is generated.
Fault message ">1 clock time master" is displayed if several devices are
parameterized as clock time master on the bus.
Fault message "Invalid time of day" is displayed if RMS705B loses its time
setting after power failure and/or if the time is not resent via bus.
Note 1: The clock in RMS705B has a backup battery for typically 48 and at
least 12 hours. The time must be reset if a power failure exceeds these hours.
Note 2: A flashing fault LED indicates invalid clock time.
