nication. Then, it can be readout and controlled using a Data Concent-
rator(DC) or a GSM Modem and from LUNA Metrum remotely.
The RF module uses 868MHz ISM band and a custom protocol by
LUNA meters for communication. It supports communication speed
of up to 200kbps.
No setup or connection is required for RF communication on the me-
ter side.
1.10.6. GPRS Communication Module
The meter can have an integrated GPRS module to support GPRS
communication. Then, meter data can be readout and meter can be
controlled from LUNA Metrum remotely over GPRS.
1.10.7. Calendar Support
LSM meters support Gregorian, Hijri and Persian calendars. All re-
cords and calendar events are stored according to the calendar type.
Default calendar of the meter is Gregorian.
1.10.8. kWh Limitation
If the meter includes this feature, it is activated by default. It can be
disabled by writing 0 or re-activated by writing 1 to 96.74.22 OBIS
code. When the subscriber reaches the monthly consumption limit
defined in 96.73.30 OBIS code, the subscriber’s electricity will be
disconnected if the feature is enabled. If the Consumption Limitation
Repeat (96.74.24) feature is enabled (value 1), the electricity can be
reconnected for Allowed Button Connect Count (96.73.33) times by
pushing the menu button of the meter. The limit is reset at the end
of each month.
1.10.9. LCD Backlight
The backlight is turned on when menu button is pressed or optionally
on read or write attempt on the meter if electricity is available.
1.10.10. Latching Relay
The electricity of the meter can be connected/disconnected immedia-
tely or at a certain time, remotely or locally by the latching relay inside
the meter. The latching relay state can be changed by the below OBIS
code and data through optical port/RS485/smart communication mo-
dule.
96.74(0X)(YY-MM-DD)(000000)
where X = 0 for connect or X = 1 for disconnect operation. Entering
an operator ID is optional. Additionally, if the latching relay is to be
connected immediately, there is no need to enter an action time while
writing the OBIS; while, a date-time of operation can be written as in
the above format if needed.
1.10.11. Non-Volatile Memory
For higher memory requirements the meter may have addtional
non-volatile memory IC.
