1. Purpose
LE-03MB is a static (electronic), calibrated electricity meter of single-phase and three-phase alternating
current in direct system. It is used for reading and recording of imported electricity and parameters of
the power supply with the ability of remote reading through a wired M-Bus network. Configuration of
the meter is done through the configuration menu accessible from the front panel and through the
communication port according to the software features of the M-Bus.
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. M-Bus protocole and communication port
Meter has a port with support for M-Bus protocol.
The M-Bus communication port allows you to combine the counters in the remote reading network.
2.3. 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 first screen lights up all display
segments and can be used as a display
check.

Total reactive energy in kVArh
The total value of the given energy is presented in two rows.
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, require a four-digit number entry while others, such as
supply system, require selection from a number of menu options. After confirming the settings the
meter confirms the adoption of a new parameter by displaying for a moment the word "good".
5.1.1. Navigation
1. Transition to the next position configuration menu.
2. Press to confirm your selection.
3. Edition of value (change of position numer by +/-1)
4. Having selected an option from the current layer, press to confirm 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 configuration 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 flashes and is set using the and buttons.
2. Press to confirm each digit setting. The SET indicator appears the last digit has been set.
3. After setting the last digit, press , to exit the numer setting routine. The SET indicator will be
removed.
