Data of the current event is lost if preceded by a power failure. Previously saved
events remain available.
 Logging is canceled and terminated if the measured value signal at the terminal
is no longer available. Logging is resumed after the signal is reactivated.
 The previous event cycle is not saved if yet another event cycle occurs within 5
minutes.

Operating hours

 The following 4 operating hours counters are available:
 They use a digital input signal to record the operating hours of any aggregate.
 Operating hours since last maintenance are counted in addition to total
operating hours.
 RMS705B generates a freely definable maintenance message when the
maintenance interval value is reached.
 Counters "Operating hours since service" continue to run until reset to 0 via
"Reset".
 Resetting counter "Operating hours since service" does not impact the
counter for total operating hours.
 The maintenance messages for the operating hours counter are displayed as
part of the fault message "Main menu > Faults".
 A name can be assigned to each operating hours counter.
 The counter can be set to any start value at the password level.
