Applications
This is a MPR-2 series 3-phase mains analyzer. It is a microprocessor based device which is designed
for measuring all parameters of an electricity mains, calculate consumptions and reflect these values on
the LCD display.
Thanks to its clock chip and flash memory of the device, the blackout logs and the processes performed
by the operator such as the time and setting changes, resets and etc. are saved in real time. These logs
can be read and followed by the Modbus RTU protocol through the RS-485 communication port.
Current connection is done according to the selected model through 5A direct connection to the current
transformer with CT25 and RJ-45 connector and mV voltage output.
The connection control function which is described in detail in the 15th page should be used against
open live ends due to possible fractures at terminals.

other than their main functions which can be accessed by pushing for 3 seconds. Button function
descriptions are as below.
BACK button (24): has 3 basic functions:
o Used for returning to an upper menu from any menu.
o As it can be seen from the notation on the button (V I F), it is used for monitoring the
Current, Voltage, Frequency and time counter values and switching between the related
screens.
o If, pushed for 3 seconds, it turns into device incident log monitoring mode.
UP button (25): has 3 basic functions:
o As it can be seen from the notation on the button (P PF), it is used for monitoring the
Total, Active, Reactive, Apparent Power, Cos φ and the values measured related with the
Power Factor.
o While, you are in a menu, it is used for moving upwards in a menu and increasing the
adjusted values.
o If, pushed for 3 seconds, the device switches into the connection test mode.
DOWN button (26): has 2 basic functions:
o As it can be seen from the notation on the button (E H), it is used for monitoring Harmonic
measurements on the Voltage-Current screen and Energy measurements on the Power
screen.
o While, you are in a menu, it is used for moving downwards in a menu and decreasing the
adjusted values.
SET button (27): has 3 basic functions:

requested to enter the Menu and the menu is accessed only if the correct PIN value is
entered.
o It is used to access the setting to be changed and save the changes, if it is required to
make changes on the settings by using the menu steps. It is enough to push the button
for a little while for this process.

Terminal Structures
The terminal structures according to the models are described in this section:
Structure of the MPR-27S-23 Terminal:
Current Terminals: K1, L1, K2, L2, K3, L3
An external current transformer must be used for the 3-phase system connection to
these terminals where the current up to 5A can be input.
Supply Terminals: A1, A2
Please, apply 85-300 VAC/DC supply connection through these terminals.
Voltage Terminals: N, L1, L2, L3
Please, apply 3-phase voltage connection through these terminals.
Digital Input Terminals: INC, IN1, IN2
As the INC terminal will be the joint point (reference), the IN1 and IN2 inputs are used
as digital inputs between 5-30 VDC. Inputs have 1 kV insulation level.
Digital Output Terminals: OC, O1, O2
10
As the OC terminal will be the joint point (reference), the O1 and O2 terminals are used
5-30 VDC
Relay Coil
MPR 2X
OC
O1
O2
as insulated outputs. As it can be seen from the following figure, these Open Collector
outputs should be fed by an external supply for operation.
Analog Output Terminals: AOC, AVO, AIO
As the AOC terminal will be the joint point (reference), the analogue current or voltage
output is ensured respectively through the AIO and AVO terminals. Only one of the
AVO and AIO terminals are used at the same time.
Communication Terminals: A(+), B(-), GND, TR
RS-485 communication terminals are used for A(+) and B(-) communication
connection. As the communication distance becomes longer, the TR terminal and GND
terminal are short-circuited and 120 ohm line termination resistance is activated and
line stabilization is completed.
11
Structure of the MPR-26S-21 Terminal:
Different from the MPR27S-23, these terminals which are used for relay output are the
terminals next to the voltage terminals. They are indicated with the key symbol on the
front view. The terminal structure of the MPR26S-21 model is as in the following:
Structure of the MPR-25S-22 Terminal:
Different from the MPR27S-23, there is not any analogue output terminals on the
MPR25S-22 model. The terminal structure of the MPR25S-22 model is as in the
following:
12
Structure of the MPR-24S Terminal:
Different from the other terminal models, MPR24S model dost not have any I/O
terminal. This terminal has only supply and measurement terminals. The terminal
structure of the MPR24S model is as in the following:
13
CONNECTION TYPES
As there are shunts at the current measurement inputs of the device, it is mandatory to use a current
transformer except for the connections of current inputs. If, the device will be used on the same current
line by means of analyzers with other shunts, it is recommended that the device is located at the extreme
point.
The device has 5 different connection types. These connection types are described in the following
schemes:
3P4W (Three-Phase Four-Wire) Connection
As it is seen below, four voltage and three current connections including the neutral line are established
in this connection type. Voltage inputs should be connected with 100 mA fuses as shown below.
14
3P3W (Three-Phase Three-Wire) Connection
As it is seen below, three voltage and three current connections are established in this connection type.
ARON Connection
Three voltage and two current connections are established in this connection type. As it is seen in the
following figure, the current connections are established with the 1st and 3rd phases.
15
3P4W BLN (Three-Phase Four-Wire Balanced)
Connection
Four voltages and one current connection are established in this connection type. The device displays
the value measured at the current input connected to the first phase on its screen for other phases in the
same value.
3P3W BLN (Three-Phase Three-Wire Balanced)
Connection
Three voltage and one current connections are established in this connection type. As it is seen below,
the device displays the value measured at the current input connected to the first phase on its screen for
other phases in the same value.

The load value needed for minimum test conditions cannot be provided.
After, the connections of the device are completed, you can check the connection you established by
using the test functionality.
The device switches into the connection test mode if the BACK button is pushed for 3 seconds. In this
mode, at least 20% of the normal voltage and 10% of the nominal current must be applied on the
measurement inputs of the device and the angle difference between the voltage and current inputs
should be lower than 30 degrees. In other words, this control can be provided for the loads over 0.87
Cos Fi value.
In this mode, the device can control the connections and if there is any fault through the current flow
directions, it can correct such faults by software or leave it to be handled manually by the operator.
If, there is any connection fault between voltage inputs, this fault can only be corrected by changing the
cable connection points.
If, you experience the fault number 12, please make sure that all connections are established and the
aforementioned minimum current and voltage values are applied on the device.
The possible connection faults as a result of the connection test process and the codes displayed on the
device screen for these faults are indicated in the following table:
17
Communication Line Termination Resistance
If, the communication distance of RS485 lines is longer than 10 meters and there are more than one
devices on the line, a 120 Ω line termination resistance should be installed between the A and B ends of
the farthest device of the communication terminal.
For this process, as it is seen from the following figure, it is enough to short-circuit the GND and TR
terminals of the device.
