EM24 W1

Introduction

Description

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

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

means of current transformers (5 A secondary output).

The wireless M-Bus communication allows to transmit the collected data.

Interface

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

Displaying of system variables

Displaying of dmd variables

EEEE

Overflow.

Note: in case of overflow of at least one current, hour

counter increase is disabled. The calculation of DMD

and the energy counters are calculated considering the

value of the measure in overflow as equal to the maxi-

mum managed by the instrument. “EEEE” in a single

phase variable automatically implies that the upper limit

of the related system variable has been exceeded, and

the indication of PF is forced to “1,000”.

Essential information

Measurement management

Easy connection

If the “Measure” parameter is set to A (easy connection), 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 the “Measure” parameter is set to B (without easy connection), both the active

imported and exported are available.

Average value calculation (dmd)

The system calculates the average value of electrical variables in a set integration interval.

Dmd values are available on display only. The dmd interval is automatically set equal to the transmission interval and it is not synchronized with the transmission

interval.

Communication

Frames

The frames are packages of messages sent by EM24 containing the variables measured. The variables and their encoding included in the frame depend on the

Notes:

• “error flag” is a diagnostic variable used to communicate an overflow condition which makes the measured data invalid:

Encryption

To ensure data privacy and prevent data access by unauthorized parties, you can enable M-Bus wireless communication data encryption.

Security proles

Two security profiles are available:

• Security profile A (ENC-Mode 5)

• Security profile B (ENC-Mode 7)

Encryption key

The encryption key is uniquely associated with each device. The key is included in a sealed envelope contained in the package of EM24.

IMPORTANT: KEEP THE ENCRYPTION KEY. In case of loss, it is not possible to recover the key and the tool can be used only without cryptography.

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 of measurement parameters.

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

Note: in MID versions the position in sealed in Lock .
