Do not dispose of this device in the trash along with other waste! According to the Law on Waste, electro coming from households free of charge and can give any amount to up to that end point of collection, as well as to store the occasion of the purchase of new equipment (in accordance with the principle of old-for-new, regardless of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health.

Purpose

LE-03MW CT is an electronic, 2-way electricity meter for three phase electricity, designed for measurement in a half indirect measurement. The built-in real-time clock allows energy consumption to be measured with different tariff zones. The device is equipped with communication interfaces: RS-485 with Modbus RTU protocol and optical port compliant with EN62056 (IEC1107) standard for remote reading and configuration of the meter.

Characteristis of the device

3-phase, 2-way energy meter;
half indirect measurement (direct measurement up to 6 A);
energy measurement in 4 tariff zones;
built-in real time clock with battery backup to switch tariff zones;
registration of total and divided into consumption tariffs:
– total active and reactive energy;
– active and reactive energy divided into individual quadrants;
8 time schedules dividing the day into tariff zones;
it can settle energy according to schedules specific for business days and weekends;
it can divide year into 8 time intervals; in each interval the energy (for weekdays) can be settled according to a different schedule;
indication of network parameters (voltages, currents, active power, reactive power, apparent power, power factor, frequency);
calculation of power demand for individual tariffs;
additional, resettable energy meter;
RS-485 port, Modbus RTU protocol;
optical communication port compliant with EN62056 (IEC1107) standard;
2× SO pulse outputs with a programmable number of pulses per kWh/kvarh;
multifunction LCD display.

Setting the current transformer

The current transformer of the meter can be set remotely via
the Modbus RTU interface or locally with the PROG button.
To manually set the transformer:

Turn the meter power off and on.
Press and hold the PROG button.
After approximately 15 seconds, release the PROG button.
The display will show a flashing transformer value (for example 0005-5).
Use the RIGHT or LEFT buttons to set the desired current trans-former value.
Wait until the transformer value disappears from the display.

Indication of energy consumption

The maximum indicated value of electricity consumption depends on the selected current transformer value.

(*) The 30/5, 80/5 and 750/5 gears can only be set via the Modbus interface..

! After filling the readout field, the meter starts counting the energy from the value of 0 kWh.

Meter number

The meter is marked with individual serial number allowing its
unambiguous identification. The marking is laser engraved and
cannot be removed.

Sealing

The meter has sealable input and output terminal covers to prevent
any attempts to bypass the meter.
Additionally, it is possible to seal the access cover to the PROG
button, which allows a local change of the current transformer
setting.

Service program

On the fif.com.pl website (on the subpage LE-03MW CT meter) a
program is available for meter configuration via RS-485 interface.
