1. Introduction: This Manual is for the EDMI Mk10 Whole Current Energy Meter. It covers the information and procedures required for the Installation and usage of the meter. It also covers some basic concepts of the meter and its uses.

2. Installation:

2.1 Dimensions and Mounting: Figure 2.1 shows the overall dimensions of the meter with a standard terminal cover. The height excludes the buttons and the ANSI fitting if present.

Fig-2.1 Over all Dimensions of the meter The Dimensions of Mk10 meter is given below. Mk10 with Long terminal Cover - 290mm(H) x 95mm(D) x 175mm(W) Mk10 without terminal cover - 210mm(H) x 95mm(D) x 175mm(W) The meter is mounted using three screws.

In general:

• Screw the first (top) screw into the wall. Leave enough space between the head and the wall for the plastic around the keyhole.

• Hang the meter on the screw using the keyhole in the back of the meter. • Insert the remaining two screws (meter base, under the terminal cover) to hold

the meter securely.

Table 2.4 lists the terminal block connections.

Table 2.1 Terminal Block connection 2.3 Connection Details: Figures 2.8 show the possible connection method in 3 (4 wire) element mode. A connection diagram label is also fixed inside the terminal cover. For proper accuracy the measurement method must be set to 3 element using EziView. Terminals 12 & 14 are not fitted in CT connected meters. The nominal voltage input range dependent on the model number of the meter. The current range depends on the current range of the meter, and should be limited to Imax.

Beneath the terminal cover (accessible by removing the two sealable screws on the top of the terminal cover) is the terminal block for voltage and current, connectors for the pulsing inputs and outputs (optional), the optional RS-232 or RS-485 interface, and the optional external battery. The sealable screws have 2.15mm diameter holes to accommodate standard sealing wire.

4. Technical Features

4.1 Dual Source Feature This Static AMR compatible TOD Tri-vector Energy Meter is having the capability of measuring Dual Source register for measurement of different electrical parameters including Active Energy(kWh), Reactive Energy(kVArh), Apparent Energy(kVAh)etc. which is supplied by Utility and supplied by DG of Franchise in separate registers for all the three phases. 4.2 Survey: Surveys allow the creation of a database for the recording of large amounts of historical data. A survey consists of a number of records, each record then consisting of a number of channels (channels are called fields in database terminology). Each channel stores one particular quantity, and each record therefore stores a record of the values of those quantities at a specific moment in time. There may be up to 256 channels in a survey. Each channel may be of any width and of any data type, with the only constraint being that the total width of all channels must be less than 65536 bytes. Each channel has a source register. When a record is stored, the source register for each channel is read and the returned value is stored into that channel in the record. The number of records in a survey in theory may be over 4 billion, but in practice is limited by memory availability.

Survey tools: The tools that record information in a survey are

• Load Survey

• Billing History

• Event Log

Load Survey: A load profile, otherwise known as a load profile, is designed to give a detailed record of energy usage. The meter has two load profiles available, each independently programmable. Each can record up to 32 channels, although generally this is limited by memory. The load profiles in the meter also have the ability to record instantaneous figures such as voltage and current. The Recording Time allocates enough memory to the profile to record for the specified time. The maximum recording time is indicated, based on available memory and the profile configuration. Load Survey – Records data for 45 days with integration period of 30 minutes. Billing History: Billing History keeps records of previous accumulated energy, maximum demand and time of maximum demand for every rate of every TOU channel. Whenever a Billing Reset occurs, all these values are stored as a previous billing period, and the current values are reset to zero. Generally a Billing Reset is generated automatically once a month. There are a maximum of 13 previous periods stored.

Event Log: The meter records the following events whenever they occur in the meter. The number of logs to be recorded under each event type is user configurable. Each entry uses 6 bytes of EEPROM. Event Logs can be downloaded from meter. The following tables provide the list of events which have been preset to appear under each type of log.

Table 4.1 List of Events

5.Communications

5.1 Optical(FLAG) Port:

The meter can have a Flag Port. Use a standard FLAG (IEC1107 physical standard) read head to connect the meter to a PC. Note that it has occasionally been found that some FLAG heads need to be rotated 180 degrees for them to work. If you have problems try this. 5.2 Modem Port:

5.2.1 RS232 Port:

The RS-232 port on the meter uses an RJ45 connector, which complies with the RS-232D standard. To connect to a modem, use a modem with an RJ45 connector, or use an RJ45 to DB9 connector adapter. RTS/CTS hardware handshaking is not supported. See the Table for connection details of TB10. Pin 1 of the RJ45 is on the right hand side. SI.No PIN no Description

Table 5.1 RS232 PIN details

* TB10-1 is connected to a +5V power source from the meter, which is designed to power an external GSM modem. Some early meters may have been built with a 2W limit.

Log Name Description

System Log Used for system events like Power on and off details

Access Log Used to track user accesses to the meter.

Billing Reset Log Records when billing resets occur.

5.3 Input ports: The inputs are passive and are isolated from all other circuits, including the other inputs. There are a variety of input voltages that may be ordered with the meter, e.g. 110V and 240V, down to 5V. Under voltage will cause the input to trigger erratically or not at all, while over voltage will cause excessive heat dissipation and possible damage to the meter. The rated voltage is the voltage that must be applied between the two terminals of the input. The inputs work with AC signals.

6. LCD Description

The LCD is primarily for displaying information from the meter’s registers for meter readers. It is also useful during installation, configuration, and diagnosing problems. It has 8 seven-segment digits to display values and 7 seven-segment digits to display description. It has arrows to indicate import and export for active and reactive energies, indicators for phase voltage, indicators for display sets A and B, battery indicator, connection type indicator for connection through local or remote port and units and multipliers.

Fig-6.1 LCD Display The LCD can come with or without a backlight. The backlight may be set to only activate while the LCD is in use, which is recommended to reduce power consumption. The turn on time of the backlight can be configured using EziView. The backlight does not operate when running on the UPS battery. To progress to the next page, press the Select button. Each time the button is pressed the display moves to the next page. The display may also be setup to automatically cycle the display through the pages, pausing if the Select button is pressed.
