2.2. Model overview

COUNTIS E23 and E24 are modular active and reactive energy meters that count and display the energy consumed. They are designed for three-phase grids and allow direct connection up to 80 A. They are equipped with a MODBUS communication bus. The COUNTIS E23 and E24 are identical in construction. The E24 is the MID version of the E23.

3. Connection

The meter is electrically connected through the 3 phases and the neutral conductor in accordance with the original instructions. The meter has an input and output for connecting the phases. If these are connected incorrectly, the meter may later output a negative value in Online Monitoring.

4. Communication

The Modbus communication available with COUNTIS E23/E24 takes place via a serial RS485 interface (2 or 3 wire), which enables the device to be operated from FEMS. In the standard configuration, 32 devices can be connected to a PC or a controller over 1200 meters using an RS485 interface.

To connect several meters in series, the RS-485 connection must be looped through, as shown in the figure below.

Note the connection of the terminating resistor (120 Ω)!

Figure 6. Looping through the RS-485 wiring

If the supplied RS485 cable is not long enough, we recommend using a LiYCY with a cross-section of 0.5 mm². This is suitable for max. 500 m. In general, the manufacturer’s specifications and recommendations must be observed.

6. Configuration

The following configuration settings must be used for use with FEMS:

Baud rate for communication	9.6
RS-485 Modbus address — Grid connection point	005
RS-485 Modbus address — PV generation	006
RS-485 Modbus address — Other generators/consumers	007…246

Follow the installation and service instructions for the meter installed to make the settings. The following steps are for simplification purposes only.

6.1. Opening the programming mode

Press the ENTER button to switch between the menu items within the configuration menu until the SETUP menu item appears.

Then press and hold the ENTER button for three seconds to enter programming mode.

6.2. Input — RS-485 Modbus address (Addr)

The following steps describe the procedure for configuring the RS-485 Modbus address.

Press the ^ button until the menu for setting the address appears

Press the ENTER button. The left-hand digit then flashes

Press the ^ button until the value of the left-hand digit is set to 0.

Press the ENTER button. The middle digit then flashes.

Press the ^ button until the value of the middle digit is set to 0.

Press the ENTER button. The right-hand digit then flashes.

Press the ^ button until the value of the right-hand digit is set to 5.

Press the ENTER button to save the entries.

6.3. Communication speed (baud rate)

The following steps describe the procedure for configuring the baud rate.

Press the ^ button. The menu item for setting the baud rate appears.

Press the ENTER button. The baud rate value then flashes.

Press the ^ button to switch between the different baud rate values. Select the value 9.6.

Press the ENTER button to save the entry.

6.4. Communication parity

The following steps describe the procedure for configuring the communication parity.

Press the ^ button. The menu item for setting the communication parity appears.

Press the ENTER button. The communication parity value then flashes.

Press the ^ button to switch between the different values. Select the value n (none).

Press the ENTER button to save the entry.

6.5. Communication stop bit

The following steps describe the procedure for configuring the communication stop bit.

Press the ^ button. The menu item for setting the communication stop bit appears.

Press the ENTER button. The communication parity value then flashes.

Press the ^ button to switch between the different values. Select the value 1.

Press the ENTER button to save the entry.

6.6. Exiting programming mode

Press and hold the ENTER button for three seconds. The "SAVE" menu then flashes with the value "y" (YES). This means that the entries will be saved. If you want to discard the entries, press the ^ button to go to the value "n" (NO)

Press the ENTER button to confirm the entry.

The configuration of the meter is now complete. Proceed in the same way to configure other meters. Please note the different RS485 Modbus addresses.

7. Diagnostic messages

The following diagnostic messages are displayed if there are connection errors or faults

7.1. Missing phases

If one or more phases are not recognized, the exclamation mark flashes at the top left of the display.

7.2. Swapped phases

If a 123 phase sequence is detected, the arrow appears clockwise on the display.

If a 132 phase sequence is detected, the arrow appears at the top of the display, rotating to the left.

7.3. Malfunction

If the message ERR appears on the display, there is a measuring device fault and the measuring device must be replaced.
