The value of the switched nominal current is (10±1) mA, the maximum allowable value is 30 mA. By default, ТМ1 generates pulses, proportional to the consumed and delivered active energy values (Ai+Ae), ТМ2 generates pulses, proportional to the consumed and delivered reactive energy values (Ri +Re). The outputs can be reconfigured to generate pulses proportional to the individual type of the metered energy or as a relay (for details, see САНТ.411152.107-05.1 РП).

To ensure the functioning of pulse outputs, it is necessary to supply DC voltage according to the scheme shown in Figure 3.3.

Figure 3.3 – Connection diagram of the meter pulse outputs

The value of electrical resistance R in the pulse output load circuit is determined by the following formula:

(3.1)

where U is the output power voltage, V.

3.4.2 Relay connectionTo implement alarm functions, meter versions with an alarm relay (AR) are provided:The switching specifications of the relay are shown in Table 2.3, modes of operation – in the

САНТ.411152.107-05.1 РП.AR connection diagrams are shown in Figure 3.4.

3.4.4 Connection of meter interfacesThe meter provides data exchange with external data processing devices via the optical port and RS485 interface

in accordance with the protocols of GOST IEC 61107-2011 and DLMS/COSEM (for meter versions Z).The optical port is designed in accordance with GOST IEC 61107-2011. The optical port is intended for local

connection of the meter via an optical head connected to the PC serial port.3.4.4.1 RS485 interface connectionThe meter versions with an RS485 interface make it possible to combine up to 256 devices (meters) on one

common bus. When connecting two or more metering devices, it is necessary to assign an individual address for each one. The meter’s RS485 interface connection diagrams are shown in Figure 3.6 a, b.

If the ground potentials at the installation sites of meters and data concentrator unit (DCU) are equal, then it is

32

enough to connect pin 17 (right) and 13 (for CE308 S31, S34) to the zero potential point, otherwise take potential equalization measures.

In the event that the length of the communication lines does not exceed several meters and there are no sources of interference, then the connection diagram can be significantly simplified by connecting the meter to the DCU or PC using only two signal wires A and B. The exact resistance value of the terminal resistors5 , as well as the need to use them, should be determined during the preliminary survey of the facility. In general, if the communication line is up to 1000 m and the exchange rate is up to 9600 bod, the use of terminal resistors is not recommended6.

а) connecting CE308 S31, S34 using connector 17 (see Figure 3.1a)

Biasing resistors (+R) and (-R) (nominal 100 kΩ) are installed in the meter and are always connected to the A and B lines, respectively. Unused biasing resistors with resistance of 560 Ω are also installed. To activate the resistors, it is necessary to close the contact pads located in the area of connector 19 (see Figure 3.1a): «R-» with «B», «R+»

5 It also depends on the cable brand, its length, linear resistance, as well as the input impedance of all other receivers in the line6 If the terminal resistor is already installed inside the data concentrator unit, it can be disconnected using the appropriate

microswitches (jumpers) of the data concentrator unit.

32 33

with «A». In order to avoid line overload, activation of biasing resistors with a resistance of 560 Ω, as a rule, is only performed for the extreme meters.

3.5 Lithium cell replacementIn the meter, an integrated CR14250BL-VY lithium cell or equivalent is used for the real-time clock.The lithium cell should only be replaced by a service company or in the workshop of the power supplying

organization that is authorized to repair and check the meter.In the meter, it is necessary to remove the seals of the power supplying organization, the service department

and state verification, remove the meter cover, and remove the top meter board from the connector. Solder out the lithium cell from the board and replace it. To replace the lithium cell, it is necessary to comply with the polarity using the symbols on the board. CR14250BL-VY lithium cell by EEMB is recommended. The lithium cell should have the following technical specifications: supply voltage +3.0 V; capacity at least 900 (mA*h); working temperature range from minus 40 to 85 °C; self-discharge max 1% per year.

After replacing the lithium cell, set the date and time, initialize the electronic seal of the body (see the САНТ.411152.107-05.1 РП).

In the meter, it is possible to install an additional lithium cell (in case that the integrated cell is discharged) without opening the meter body. To connect (or replace) it, you must unscrew the cell compartment cover screw and remove the lithium cell container, solder out the lithium cell (if it was previously installed) and replace it. When replacing the lithium cell, mind the polarity according to the signs on the cell compartment. Panasonic BR2330 or equivalent lithium cell is recommended. The lithium cell should have the following technical specifications: supply voltage +3.0 V; capacity at least 255 (mA*h); working temperature range from minus 40 to 85 °C; self-discharge max 1% per year.

Note – When the meter is off, replacing the lithium cell will stop the clock (the «Attention» icon is displayed on the LCD), therefore, after replacing the lithium cell, the current time must be programmed (the «Attention» icon will disappear).

ATTENTION! When the meter is on, the battery has phase voltage. After replacing the lithium cell, install the board in its original place, close and seal the meter, and verify it. With each replacement, it is necessary to make a note in the Data Sheet – who replaced the lithium cell, when and the type of the replacement cell.

3.6 Meter configurationConfiguration is carried out according to the САНТ.411152.107-05.1 РП, which is available at the manufacturer’s

website www.energomera.ru/ru/products/meters/ce308-all

4 READING THE METER

The meter can be read both manually and in the automated mode.In the automated mode, full information on energy consumption can be obtained using a PC or AMI system via

the interface (see САНТ.411152.107-05.1 РП).In the manual mode, data is displayed on the LCD in a window eight decimal places wide (with a decimal point).

4.1 Displaying information on the LCDTo meet the requirements of IEC 62052-11:2003 to the counting mechanism for meters of various versions,

various display options of the counting mechanism on the LCD were selected (Table 4.1). Due to the fact that the meter keeps records on the primary side, the display window of the counting mechanism automatically shifts to the left by an amount proportional to the power transformation ratio (KP = KV • KC), setting the position of the decimal point and introducing the necessary multiplier to display energy (power), voltage and current, respectively.

An example of displaying energy window on the LCD of a transformer connection meter 57.7 V 5A is given in Table 4.1.
