Key Features

5.1 Electric Power Measurement

• Measuring & recording load profile of import/export active & reactive energy, four-quadrant reactive energy, and apparent energy.
• Measuring, storing profile of voltage, current, power, power factor, etc.
• Remote on-demand retrieval of instantaneous metering data.
• Configure multi-channel energy and recording.
• Multi-tariff measurement function, energy registers are stored in HEX format as 6 byte variables. LCD can display maximum 8 digits. Number (0-3) of measurement display decimals on LCD can be configured by manufacturer with respect to meter type. The maximum display and roll-over value is 99999999 kWh.
• The device is designed so that electric circuitry and insulation won’t reach temperatures that would negatively affect the device operation under normal conditions of its use.

Summation methods by quantity ∑+A / ∑-A:
Summation by quantity separates the positive from the negative values of the individual phases. Measured quantity ∑+A therefore only includes the positive values, measured quantity ∑-A only the negative values, provided any are present. In case of a connection error the meter measures correctly the real energy consumption. It also measures a real export in the correct way.
Summation methods by vectors +A / -A:
As in Ferraris meters the meter summates the values of the individual phases taking account to the sign. With differing signs (energy directions) the sum corresponds to the difference between the positive and negative values.
5.2 Display
LCD display contents include the main part and auxiliary part. The auxiliary part of display indicates the category of measuring value and the unit of corresponding measurement value.
CLMS300 can display all measured parameters and other recorded data. Display contents can be configured, at the end of user manual, a Configurable Display list is provided.
5.2.1 User modes
The meter has two types of user modes, the Service Mode and the Normal Mode that will display different sets of data on LCD for the end user to navigate. Usually service mode is configured with extended data for utility field agent to record data or investigates issues while normal mode provides basic information for the residence of household. Service Mode can be configured whether to be entered at meter’s power-up or skipped, i.e. meter enters Normal Mode directly when power-up. Furthermore the entering of service mode can be protected by whether to associate with terminal cover removal required.
With the Service Mode, user can configure the meter by specifying what parameter should be displayed once the meter is powered on. With the Normal Mode, user can configure the meter by specifying what parameters should be displayed and define the time  interval of displayed items.
User can also switch Normal Mode to Service Mode by long press the Display Button for 8 seconds. The display duration for service mode is configurable. Once service mode finishes sequentially displaying all of the configured items or the duration has expired, the meter will exit Service Mode then enter Normal Mode automatically.
5.2.2 Display modes
There are two display modes, the Auto scroll display mode and Manual scroll display mode. In Auto scroll display mode, when the meter is powered up, full screen displays for 3 seconds, then meter enters the Auto scroll display mode.
LCD sequentially displays the data and scrolls every 10 seconds (configurable, default 10s) and when Auto-scrolling completes scrolling all the items, it will automatically rotate back to the beginning.
The default auto scroll time interval is 3 seconds for showing the screen of categorized measuring items, but user can set up this time period to be 1~100 seconds time range. During meter in auto-scroll display mode, Manual scroll mode can be activated by pressing Display button from the upper right corner of the meter, and the next item in the configuration list can be manually scrolled as per button press. When there is no key pressed for more than 3s (default), the meter will resume auto-scroll mode.
The meter can enter test mode with a command, the test mode have features as below:

• Display the value of energy register at the current rate, the energy is the first channel which is configured.

• Displaying registers in 3 decimal format.

• Activation test mode with a command via optical port. Deactivation of test mode may come after either power-cycle or through a command.

• The communication interface is not interrupted when the meter is in test mode.

• When the incorrect order of meter line phase is detected, the related icon (phase indication) will be flashing as a sign of alarm for such abnormal event.

• When the remaining of backup battery is below configured low voltage threshold, the icon of battery indication will be flashing.

• The meter supports the backlight function for LCD. When the meter is in the normal operation, pressing the Display Button once can switch ON LCD backlight for 5 seconds.
  5.3 Real Time Clock and Tariff Rate

The meter is equipped with internal RTC circuit supported by temperature compensation function.
The frequency of RTC is 1Hz and its accuracy is kept as 0.5s per day with 23°C.
The switching between the summer and winter time performs automatically and it is possible to define by user. This functionality is possible to switch off. A switch occurs within one minute between the times. The time failure will not change the device’s  ehaviour (resetting, a change of metrological properties, change of tariff, etc.)
RTC is possible to synchronise via the IR and BPL interface. The RTC is synchronised by NTP server each 4 hours and also it is possible to set any time defined by the user using the relevant software.
5.3.1 Tariff rate indication
There are 6 reversed triangle icons to indicate the 6 tariff rate. The active icon shows which tariff rate is selected at at present time of use. The VT and NT assignment on label is as follows: 1.8.2=VT, 1.8.3=NT. The remaining two tariffs are 1.8.1 and 1.8.4.
Planned tariff control is provided using a TOU table recorded in the electricity meter. Any TOU table settings (including seasons, special days, etc.) id included in a single parameterisation file of this TOU. The TOU table can be changed remotely. The TOU table is possible to record onto the device through parameterisation software and it performs independently of other electricity meter parameterisation.
The tariff is possible to switch at least 12 times in 24 hours. And it is possible for the user to define at least four seasons in any time interval. It is possible as well to specify switching tariffs for weekends/week days and user-selected special days.
After restoring voltage the switching element (relay) will switch to currently valid state according to the TOU table.
5.4 Program

• Meter’s parameter can be re-configured over the BPL power line interface or PC software via Optical port.
• Different level password will be required for various group of user to perform above set up.

5.5 Measuring and Monitoring

• Meter can measure, record and display the following measurements for the individual of single phase, such as the voltage, current, power, power factor etc. The measuring accuracy for active power is within ±1%.
• Meter can monitor power quality in real time, such as Voltage, Power etc. User can pre-set up the limit value for the specific parameter, when the measured value exceed the limit value, the meter report the situation as an Event.

5.6 Record of Event
The events are generated and recoded helping remote monitoring and diagnostic. There are several alarms recorded by the meter as follows:

• Removal of meter housing cover, backup battery/ripple relay cover, and terminal cover.
• Detection of low battery for backup battery.
• Detection of the strong magnetic field around meter.
• Detection of individual phase failure and main power outage.
• Reverse tamper detection.
• Over/under voltage threshold tier and actual voltage recorded when those events occur. Over power threshold notification for contracted operation failure of performing disconnect.

These are extended by the events:

• TOU table change
• Permission to restore supply
• Restoration of supply
• Voltage failure and restoration of voltage
• Removal of terminal cover, phase failure and magnetic field detection

The firmware change and attempts at logging into the device are addressed as follows:

• Meter and SCU firmware/software upgrade have record stored in Data Concentrator database. Once the upgrade process is done, Data Concentrator will generate a report and send to MDM, but the upgrade report is not designed as a metering event.
• Meter login attempts are designed as metering events and stored in Module, later will be retrieved by SCU and then MDM.
• The memory capacity of the event log is 200 events/alarms including timestamp.

5.7 Communication functions

The meter is equipped with 1 Optical port, 1 RS485 port and 1 BPL module with the communication interface over power line. Each port is designed independently so the damage to one  portwill  not impactto other ports’ function.
For Optical port, the default Baud rate is 300bit/s. User can switch to different baud rate. The transmission and reception diode of an optical interface are placed on a common horizontal axis.
For the RS485 port, the baud rate for communications can be configured flexibly, the standard Baud rate is 300bit/s, 600 bit/s,1200bit/s, 2400 bit/s, 4800 bit/s, 9600 bit/s, 19200 bit/s. The RS485 only supports passive mode communication.
The communication over optical port and BPL interface will follow “IEC62056-21” and other associated standards.
