1.9.4. Main Cover and Terminal Cover Openings
The first main cover opening date and time information is stored in
the non-volatile memory of the meter. It can be read by OBIS code
“96.70”.Terminal cover opening date and time of current and past 24
months are recorded in the non-volatile memory. The current informa-
tion can be read by OBIS code “96.71” and the past information can
be read by OBIS codes from “96.71*1” to “96.71*24”.
1.9.5. Advanced Terminal Cover Opening Event (Optional)
The last 30 terminal cover opening events in the last month are recor-
ded along with the date and time of occurence. The current record can
be read by 96.91 OBIS code, while the previous month’s records are
read using 96.91*1,.....,96.91*12 OBIS codes.
1.9.6. RTC Failures
When RTC failure occurred, a clock icon is displayed on the LCD.
In this failure condition, the meter only records to T1 tariff. The icon
disappears and the fault is cleared when date and time information
is written to the meter. The meter can optionally display a constant
message on its screen in this case unless the menu button is pressed
and auto scrolling is off.
1.9.7. Magnetic Interventions
The last 10 intervals when magnetic field is applied and the number
of magnetic interventions are stored in the non-volatile memory of the
meter. The number of magnetic interventions can be read by OBIS
code “96.80” and the date and time information of last magnetic in-
terventions can be read by OBIS codes from “96.80*1” to 96.80*10”.
1.9.8. Production Date
The production date is stored in the memory and can be read with
OBIS code “96.1.3”.
1.9.9. Meter Status Recorders
LSM Series Meters have 4 status codes for reading the meter in-
formation, errors, warnings and features. The statuses have the fol-
lowing OBIS codes:
F.F.0: Critical Meter Errors
F.F.1: Warnings
F.F.2: Meter Information
F.F.3: Meter Features
Each status has a structure in the form of FFFFFFFFh. One F cor-
responds to 4 bits in binary and each bit is either 1 or 0. The meaning
of each bit which is set is described below:
From right to Left (LSB to MSB):
F F F F F F F F 1111 1111 1111 1111 1111 1111 1111 1111
STATUS0:
1: meter time was/is invalid
1: rtc module error occured
1: meter is uncalibrated
1: reserved
1: soft reset occured
1: hard reset occured
