1.PURPOSE

E3-LE-03MQ CT is a static (electronic) calibrated electricity meter of single-phase or three-phase alternating current

in a direct system. It is used for reading and recording of consumed electric energy and mains parameters with remote

readout via a wired RS-485 network. The meter works with current transformers (CT) with 1 A or 5 A secondary current.

The conguration of the meter is done through the conguration menu accessible from the front panel and the commu-

nication port according to the software features of the Modbus RTU protocol.

2. UNIT CHARACTERISTICS

2.1. Measured value

The unit can measure and display:

• line voltage and THD% (total harmonic distortion) of all phases

• line frequency

• currents, current demands and current THD% of all phases

• power, maximum power demand and power factor

• active energy imported and exported

• reactive energy imported and exported

2.2. Current transformers (CT)

The meter works with current transformers (CT) with 1 A or 5 A secondary current. The appropriate value of rate and

the secondary current of the connected transformer should be set in the meter.

For example: using a 100/5 A current transformer, you should set the secondary current CT2 to 5 and the rate CTrate

to 0020. To get the CT rate to enter you need to divide a primary current value by the value of the secondary current

(100/5 = 20).

WARNING!

The settings for the current ratio ( CT2 and CT rate) and voltage ratio ( PT2 and PT rate) can only be made

once. It is a legal requirement of the MID Directive. Once set the rate cannot be changed.

E3-LE-03MQ CT – User manual

2.3. RS-485 communication port and Modbus RTU protocole

The meter is equipped RS-485 port with Modbus RTU protocole.

The RS-485 communication port allows you to connect meters into a network of remote reading.

2.4. Pulse output

The meter has two pulse outputs for mapping the counting of active and reactive energy.

Output 1 - Terminals 9/10 - programmable, can be set to work for active or reactive energy and parameters: impulsing

and pulse length.

Output 2 - Terminals 11/12 - for active energy, impulsing is 3200 pulse / kWh.

3. START-UP SCREENS

The rst screen lights up all display

segments and can be used as a display check.

Information about software version.

The interface performs a self-test and indicates

the result if the test passes.

Select the voltage and current display screens.

In set up mode, this is the „Left“ or „Back“ button.

Select the frequency and power factor display screens.

In set up mode, this is the „Up“ button.

Select the power display screens.

In set up mode, this is the „Down“ button.

Select the energy display screens.

In set up mode, this is the „Enter“ or „Right“ button.

4.1. Voltage and current, harmonic

Each successive pressing of the button selects a new range:

Phase to neutral voltages (3p4w).

Current on each phase.

Phase to neutral voltage THD% (3p4w).

E3-LE-03MQ CT – User manual

Current THD% for each phase.

4.2. Frequency, power factor and demand

Each successive pressing of the button selects a new range:

Frequency and power factor (total).

Power factor of each phase.

4.3. Power

Each successive pressing of the button select a new range:

Instantaneous active power in kW.

Instantaneous reactive power in kVAr.

Instantaneous volt-amps in kVA.

Total: kW, kvar, kVA.

E3-LE-03MQ CT – User manual

4.4. Energy measurements

Each successive pressing of the button selects a new range:

Imported active energy in kWh.

Exported active energy in kWh.

Imported reactive energy in kVArh.

Exported reactive energy in kVArh.

Total active energy in kWh.

Total reactive energy in kVArh.

The total value of the given energy is presented in two rows.

10 E3-LE-03MQ CT – User manual

The top row presents the higher values, the bottom row presents the lower values + fractional value.

For example:

Indications: 0027 - top row; 845.3 - bottom row presents the value of 27845.3 kWh.

5. SETUP

5.1. Setup entry methods

Some menu items, such as password and CT, require a four-digit number entry while others, such as supply system,

require selection from a number of menu options. After conrming the settings the meter conrms the adoption

of a new parameter by displaying for a moment the word „good“.

5.1.1. Navigation

1. Transition to the next position conguration menu.

2. Press to conrm your selection.

3. Edition of value (change of position number by +/- 1)

4. Having selected an option from the current layer, press to conrm your selection.

The SET indicator will appear.

5. Back to the higher menu level. The SET indicator will disappear and you will be able to use

the buttons, again to select further options.

6. exit the conguration menu to the measurements screen.

5.1.2. Number entry procedure

When setting up the unit, some screens require the entering of a nuber. In particular, on entry

to the setting up section, a password must be entered. Digits are set individually, from left to right.

The procedure is as follows:

1. The current digit to be set ashes and is set using the and buttons.

2. Press to conrm each digit setting. The SET indicator appears the last digit has been set.

3. After setting the last digit, press to exit the number setting routine. The SET indicator

will be removed.
