EM24

Introduction

EM24 is a three-phase energy analyzer for DIN-rail mounting, with configuration joystick, frontal selector and LCD display.

The direct connection version (AV2, AV9) allows to measure up to 65 A, the CT connection version (AV5, AV6) allows to measure up to 34875

A by means of current transformers (5 A secondary output).

The DHCP function is able to speed the commissioning and all the configuration parameters can be set up via UCS.

UCS (Universal Conguration Software)

UCS desktop is available for free download. It can be connected to EM24 via Ethernet (Modbus TCP/IP) .

The following is possible with UCS:

• configure EM24 (online or offline)

• view system status for diagnostics and configuration checks function overview

EM24 E1 use

Introduction

EM24 is organized in two menus:

• measurement and information menu: pages used to display the measurement pages, information relevant to the programmed parameters

and instrument firmware release

• settings menu: pages used to set parameters

Display

The display is divided into 3 lines.

Symbol Description

Displaying of phase-to-neutral system voltage

Displaying of phase-to-phase system voltage

Displaying of max values

User ID

Displaying of system variables

Displaying of dmd variables

EEEE

Overflow.

Note: the DMD calculation, the hour-counter and the

energy meters functions are inhibited and the alarm

outputs are activated. The indication “EEEE” in a single

phase variable automatically implies the overflow condi-

tion of the relevant system variable, and the PF indica-

tion is forced to “0.000”.

Network parameters setting

Setting network parameters via DHCP

Step Action

1 Install EM24

2 Enable DHCP and exit with End

3Connect the EM24 to the LAN network to which the PC is connected

4Access the Info pages to view the assigned network parameters

5Start UCS software and connect to EM24 via Manual connection> Modbus TCP

6 Enter the IP address displayed on the Info page (see point 4)

7 Access the settings, disable DHCP and assign the required network parameters (assigned by network administrator)

Setting network parameters without DHCP

Step Action

1 Install EM24

2 Disable DHCP (default setting)

3Connect the PC to the EM24 via Ethernet cable (point to point connection)

4

Set the PC network properties as follows:

• static IP address

• IP address of the same class as the EM24, e.g. if the IP of EM24 is 192.168.1.10 (default), you can set the PC address to

192.168.1.20

• Subnet mask: 255.255.255.0

• Gateway: not necessary

5Start UCS software and connect to EM24 via Manual connection> Modbus TCP, enter the EM24 IP address

(192.168.1.10 by default)

6 Access the settings and enter the required network parameters

7 Disconnect the Ethernet cable and connect the EM24 to the network to which the Modbus master is connected

Applications

Note: if an application with easy connection is selected, for the calculation of the active energy the power is always integrated, both in the case of imported

and exported power . The current direction does not affect the measurement. If an application without easy connection is selected, both the active imported

and exported are available.

Tariff management

Managing taris via Modbus command

Change the tariff by entering the value corresponding to the current tariff according to the following table in the 1201Fh registry:

Current

tariff

Register

T1 1

T2 2

T3 3

T4 4

Note: the tariff management is not available in SFA models

Disabling tari management

Set tariff management as disabled or enter 0 (default value) in the 1201Fh register.

Frontal LED and selector

Frontal LED

The frontal red LED flashes proportionally to the active imported energy consumption if the selector is in - 1 - 2 position, and to the reactive inductive

energy consumption in kvarh position. Any kind of negative (exported) energy will not be managed by the front LED.

Frontal selector

• Lock position: the frontal selector prevents from accessing the programming mode

• 1, 2, kvarh position: quick access to measuring pages. Each position is associated with one measuring page according to the following table:
