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 higher cur-

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

UCS (Universal Conguration Software)

UCS desktop is available for free download. It can be connected to EM24 IS model via RS485 (Modbus RTU) .

The following is possible with UCS:

• configure EM24 (online or offline)

• view system status for diagnostics and configuration checks function overview

EM24 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 water cubic meters

Displaying of gas cubic meters

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”.

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.

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, 3 (kvarh ) position: quick access to measuring pages. Each position is associated with one measuring page according to the following table:

Alarm types

Up alarm (on Al 1 ≥ off Al)

The alarm activates when the monitored variable exceeds the on Al value for a time equal to the activation delay (t del) and deactivates when

the values drops below off Al.

Down alarm (on Al < off Al)

The alarm activates when the monitored variable drops below the on Al value for a time equal to the activation delay (t del) and deactivates

when it exceeds off Al.

Maintenance and disposal

Cleaning

Use a slightly dampened cloth to clean the display. Do not use abrasives or solvents.

Responsibility for disposal

The product must be disposed of at the relative recycling centers specified by the government or local public authorities. Correct disposal

and recycling will contribute to the prevention of potentially harmful consequences to the environment and persons.
