Description
The Milur 107 is a single-phase smart meter, ideal for measuring
electrical energy consumption. The Meter is direct pass-through, so
it does not require current transformers. It is equipped with a built-
in ARM microcontroller and contains a variety of interfaces for
exchanging information with external devices.
The meter is designed to account for active and reactive electrical
energy in two-wire networks of alternating current with a rated
voltage of 110V/230V and frequency 50/60 Hz.
The basic (max) load current is 5 (80) A.
The Meter, depending on its design, is made for both indoor and
outdoor applications. The outdoor enclosures are protected by IP51
and IP54 protection.
A Meter with reduced terminal covers requires additional protection
from direct water ingress.
The measuring unit of the outdoor meter has an IP20 degree of
protection. The Meter is intended for the organization of one and up
to four tariffs of differentiated accounting, both by time of day and
by the level of consumed electricity and power.
Electrical Energy Consumption is shown on the LED (liquid crystal
display) screen on the front of the meter.
The meter has two pulse outputs galvanically separated from the
network for recording active and reactive electrical energy. The
meter can be operated both autonomously or as part of an

Remote Operation
Summary
To exchange information with a Meter via RS-485 interfaces and
optical port you can use universal interface converters (for
example, PI-2 and USO-2). To exchange information with meters
equipped with PLC modems, ZigBee and RF it is necessary to use
the interface converter "Milur IC" TSCN.468369.500. To exchange
information with meters equipped with modems RF868 and PLC.G3
/ RF868 use data collection and transmission device of the
TSCN.424170.001. The converter is connected to the USB port of
the computer and Configured with the Milur Meter Configurator
software for a specific type modem (interface). The connection with
the Meter is established after specifying the corresponding fields of
the Meter address program, access level, password level access,
and the number of the virtual COM-port on which the converter
was installed. If all the options are specified correctly and the Meter
is in the network coverage area, clicking the "Open communication
session" button will establish the connection with the Meter. A
detailed description of the organization of the network is located in
the operating instructions (user manual) on the inverter interfaces
"Milur IC".
Actions to change the modes and options of the Meter should not
be carried out arbitrarily and should be strictly controlled by
operating organizations. Access to the meter should be protected
from malicious tampering. Some Measures of protection from
unauthorized actions with the Meter is provided, such as non-
erasable tamper logs. When working with the serial interface we
recommend providing password protection for all possible
commands.

Remote Operation (Continued)
The set of allowed commands is divided into group and individual.
The Meter is provided with two levels of access: 1st level of access
"user", and 2nd level of access "administrator". For each access
level, a separate password of six characters (six bytes) is allowed.
For any discrepancy between the meter password/address and the
password/address specified in the command, the command will be
interpreted as wrong and will be rejected by the Meter. In case of
incorrect entry of the password three times the Meter locks the
recording channel for 30 minutes. Session lock time is
programmable through available interfaces.
Each Meter is given the following default passwords and addresses:
- The password of the first level:
FF FF FF FF FF FF (255 255 255 255 255 255);
- The password of the second level:
FF FF FF FF FF FF (255 255 255 255 255 255);
- Exchange rate 9600/8N/1;
- The Meter address is 255 or the last three digits of the serial
number are less than 255,
- The passwords and addresses can only be changed via a serial
interface.
When operating Meters after changing passwords and / or
addresses, pay special attention to the preservation (memorization)
of the latter. Recovery is possible only through the violation of the
Meter seal.
Measures to Prevent
Unauthorized Access
In addition to password protection, there is a hardware jumper for
protection calibration factors of the Meter. Access to calibration
factors is possible only with violation of the Meter seal.

Tariff Schedule
The meter measures consumed energy with four tariffs. Switching
from one tariff to another is made automatically in accordance with
the specified tariff schedule. The tariff schedule is set by the
interface for each from twelve months. The tariff schedule provides
for 8 tariff zones. The tariff zone provides the time for switching to
another tariff and the number of the new tariff. Tariff switching can
be set for the following days: business day, holiday, Saturday, and
Sunday. Switching of the tariff schedule should be recorded
consecutively, without omissions. The switching time for the next
tariff schedule must be set strictly in order to increase the time. If
the switching time in the current record will be less than in the
previous record, then the current recording rate will be set. The
records of the tariff schedule for the day should start from the
beginning of the day. In the first record the tariff schedule for the
day should be set to 00:00. Changing the tariff schedule is possible
only at the access level "administrator".
Load Control
To perform this function, the impulse output of active energy can
be transferred to three additional modes: "load on", "load off "and"
automatic control ". When the "load on" function is selected the
pulse output will be in the load on state. When choosing function
"load off", the pulse output will be periodically set to load
disconnected status. The "automatic control" function allows
monitoring of the load power. To perform this function, you must
specify threshold of automatic control, for example, 2 kW.
Automatic control threshold load is the average value of the power
averaged over the interval integration of the meter's power profile.
When the load exceeds this limit, the pulse output will be
transferred to the "load disconnection" function. Re-activation of
the load is done by the command on the interface. Meters with
integrated load-shedding relays enable load on / off (selection of
functions of the built-in load control relay tab "Limits") in the
modes "Load is always on", "Load constantly off ", “Automatic load
control", “Semi-automatic control load”. Re-enabling the load in
semiautomatic control mode is possible only through the interface
and by pressing any of the meter buttons. In the "Automatic load
management" mode, re-enable is performed automatically and at
the end of the current profile averaging interval power (at the end
of the current half-hour interval.
