Applications
MPR-4 Series devices are microprocessor-based devices which are designed to measure all parameters
of an electrical network, calculate the consumption values and display these on its LCD screen.
Measured parameters will be recorded in real-time thanks to internal flash memory and Real Time Clock
chip. These recorded values then can be accessed and monitored remotely via RS-485 line with Modbus
RTU protocol. Ethernet feature can be used instead of RS-485.

Button Functions
In addition to their main functions, the 5 buttons on the front panel can be used as shortcut buttons for
easily reaching screens.
ESC button (9): It has 3 main functions:
Exiting from any menu is done by pressing ESC button.
While on measuring screen: As seen on the symbols (V I F) above the button, it is used to
browse between voltage, current and frequency measurement screens.
While on measuring screen: As seen on the symbols (Event) below the button, event screen is
reached when pressed for 3 seconds.
BACK Button (10) : It has 3 main functions:
While on measuring screen: As seen on the symbols (P PF) above the button, it is used to
browse between active power, reactive power, apparent power, power factor and Cos φ
measurement screens.
It is used to select the previous digit while entering a numerical value in the menu or to browse
back to a previous menu level.
While on measuring screen: As seen on the symbols (Test) below the button, connection control
is reached when pressed for 3 seconds.
Down Button (11) : It has 2 main functions:
While on measuring screen: As seen on the symbols (E Clock) above the button, it is used to
browse between import/export active energy consumption, reactive energy consumption, tariff
and time information screens.
While on menu screens: It is used to browse between menu options and to decrease a value
during adjustment.

5. INSTALLATION
Device has 5 different connection configurations. These configurations are explained with diagrams
below:
1. 3P4W (3 Phase with Neutral) Connection
For this configuration, four voltage connections (including neutral line) and four current connections are
used. Voltage inputs should be connected with 100 mA fuses as shown below.
2. 3P3W (3 Phase without Neutral) Connection
For this configuration, three voltage connections and four current connections are used.
9
3. Aron without Neutral Connection
For this configuration, three voltage connections and two current connections are used.
4. 3P4W BLN (3 Phase Balanced with Neutral) Connection
For this configuration, four voltage connections and one current connection is used.
The device shows the same current value, which is measured from the first phase, for the unconnected
phases.

Phase-2 current direction is reversed
3
Phase-3 current direction is reversed
4
Phase-1 and Phase-2 voltage connections are reversed
5
Phase-1 and Phase-3 voltage connections are reversed
6

7
Voltage connection phase sequence will be changed as L1,L2,L3 - L3,L1,L2.
For this configuration, three voltage connections and one current connection is used.
The device shows the same current value, which is measured from the first phase, for the unconnected
phases.
6. CONNECTION TEST
After finishing device connections, you can check the connection that you’ve done by using the
automatic test function.
When you press the BACK button for 3 seconds, it switches to test mode. During this mode, at least 20%
of the nominal voltage must be applied to the voltage measuring inputs, at least 10% of the nominal
current must be applied to the current measuring inputs and the angle difference between current and
voltage inputs must be less than 30 degrees.(cosφ value should be between inductive 0,87 and
capacitive 0,87.)These test conditions must be met.
During connection test, the device controls the connections and it can correct them internally or it can
leave the physical correction to the user.
If there’s an error between voltage inputs, it can only be corrected by changing physical connections.
If you encounter Error 12, make sure that all connections are done and minimum current/voltage values
are applied to the device.
On the following table, possible connection errors that may be encountered during connection test and
their corresponding error codes that are displayed on the device screen.
