3.3 MAXIMUM DEMAND RESETIt is possible to reset the MD is following three ways.
a. CMRIb. Auto Reset : MD shall be reset automatic at 00.00Hrs on the date for
which billing date is programmed. (for e.g. 1st day of month).
3.4 LOAD SURVEYThe following parameters are provided for load survey with 30 minutesintegration period.
a. Total kWhb. Total kVAhc. Utility kWhd. DG kWh
Load survey is available for last 120 days.
3.5 TOD : The meters have been programmed for 6 TOD slots. The defaultTOD slot timings are as follows :
Slot 1 : 00.00 hrs. to 06.00 hrs.
Slot 2 : 06.00 hrs. to 18.00 hrs.
Slot 3 : 18.00 hrs. to 19.00 hrs.
Slot 4 : 19.00 hrs. to 21.00 hrs.
Slot 5 : 21.00 hrs. to 23.00 hrs.
Slot 6 : 23.00 hrs. to 00.00 hrs.
3.6 POWER ON/OFFPower On/Off event is recorded when ever DG Power goes off for more than5 minutes. Last 20 Power On/Off events are recorded by meter in FIFO basis.
4. DISPLAY DETAILS : As soon as the meter is powered On, it shall show theversion number of the firmware.
Then it shall go to first display parameter.
There are two modes of display :a. Auto scroll Modeb. Push Button mode
- 2 -
a. Auto Scroll Mode : Auto scroll mode always displays the following parameter.
