Programming Guide | VLT® HVAC Drive FC 102
The drive has no backup of the clock function. The set date/time resets to default (2000-01-01 00:00) after a power-down unless
a real-time clock module with backup is installed. Therefore, the logging is stopped until date/time is readjusted in parameter
-70 Date and Time. In parameter 0-79 Clock Fault, it is possible to program a warning if the clock has not been set properly, for
example, after a power-down.
Select the type of period for logging consumption: [0] Hour of day, [1] Day of week, or [2] Day of month. The counters contain the
logging data from the preprogrammed date/time for start (parameter 23-51 Period Start) and the numbers of hours/days as programmed
for parameter 23-50 Energy Log Resolution. The logging starts on the date programmed in parameter 23-51 Period Start and continues
until 1 day/week/month has passed. The counters contain data for 1 day, 1 week, or 5 weeks back in time and up to the actual time.
The logging starts at the date programmed in parameter 23-51 Period Start. In all cases, the period split refers to operating hours (time
where the drive is powered up).

When mounting VLT® Analog I/O Option MCB 109, a battery backup of the date and time is included.
Set the date and time at which the energy log starts updating the counters. First, data is stored in counter [00] and starts at the time/date
programmed in this parameter. Date format depends on the setting in parameter 0-71 Date Format and time format on the setting in
parameter 0-72 Time Format.
