issued, the over current event doesn’t disconnect the lr until the end
of the month; if a manual disconnection is issued, the lr stays dis-
connected forever until the next manual connection command if this
feature is enabled.
1.10.17. Auto Disconnect on Very High Voltage
If this feature is supported in the meter, 96.74.26 OBIS code can be
read or written to. If this feature is supported and enabled in the meter
(value 1), when more than 320V is applied to the monophase meter
for 3 seconds, the meter disconnects its latching relay to protect the
consumer’s devices. It reconnects its latching relay if less than 320V
is applied to the monophase meter for 3 seconds.
This feature works independently from Over/Under Voltage Record
feature. Moreover, this feature overrides Auto Disconnect LR on Over/
Under Voltage (96.74.20) feature. In other words, if both features
(96.74.26 and 96.74.20) are enabled, 96.74.26 feature will be used;
whereas, if 96.74.26 is disabled (value 0) and 96.74.20 is enabled
(value 1), 96.74.20 feature will be used.
1.10.18. Meter Write Logs
LSM series meters can keep logs of the writings to the meter, along
with their date-time, password level, operator id and OBIS code inclu-
ding its data. The writing log is read in (YY-MM-DD,
hh:mm|A1|000000|<OBIS code with data>) format, where A is the
password level (0,1,2).
The complete writing logs can be read by asking the meter 96.92*X(00)
OBIS code starting with X as 1, and incrementing X until an empty wri-
ting log data (00-00-00,00:00|00|000000) is received.
1.10.19. Programmable LCD
LSM series meters have an optional feature that allows configuration
of lcd pages as desired. The customer can select which OBIS code
values to display on LCD in which order. The Programmable LCD
tab in LSM GUI software is used to define the lcd pages by entering
their OBIS codes in desired order, seperately for main menu and sub
menu.
Contact the manufacturer to request non-standard OBIS codes to be
displayable on LCD.
1.10.20. Modifiable LCD Fraction
The number of integers and decimals displayed on LCD for consump-
tion data can optionally be modified using the OBIS code 96.90.7(XY),
where X is number of integers and Y is number of decimals to display.
1.10.21. Relay Output
A relay output is available if requested. It can be opened or closed by
96.74.1 obis code. Relay has two output connector on meter cover.
These are NO or NC and COMMON relay pins. If relay is switched on
then output connectors will be in closed or open state. The relay has
two output connectors on meter cover as NO and COMMON relay
pins. The relay can be switched on or off by writing 1 or 0 to 96.74.1
OBIS code, respectively.
