SETUP
Setting up MPR50 on the Network and Configuring its Settings:
After connecting the device as mentioned in the users manual, supply energy. In order
for your measurement and applications to be correct, make the necesarry configurations
in the SETUP menu.
SETUP To enter to the SETUP menu,
while in the Instantaneous Values menu;
Press the ENTER button. (The ENERGY menu is displayed)
Find the SETUP menu by scrolling using the UP/DOWN buttons.
The image of screen is at
side while in this menu
Sub-menus under the SETUP menu and what these sub-menu settings can be used
for are explained in detail below.
Standards which are applied to the device:
EN 61000-6-2, EN 61000-6-4, EN 55016-2-1, EN 55016-2-3, EN 55011,

INSTALLATION DIAGRAM
Important note for making system connection;
First, connect the supply and voltage measurement inputs. Apply energy and
measurement voltage to the device. Observe the existence of three phases from
LCD screen.
indicators must be seen. If indicator (phase sequence is
not correct) is seen in addition to these indicators, cut the energy and measurement
voltage and change the direction of 2 phases.
At next step, you can connect current and another connections as mentioned in
the installation diagram.
* This box consists of 1 User Manual CD, 1 Installation Guide, 2 clamps and
2 screwed clamps.
DIMENSIONS
Panel Cut Dimensions
1. The device fits into a Type 19 square cut out (91 mm x 91 mm).
2. Remove the thumbscrews, then slide out the securing brackets from the rear panel.
3. Place the device through the panel cut-out, then slide the securing brackets
back into the slots on each side of the device.
4. Tighten the thumbscrews so that the securing brackets bear on the rear of the
panel into which the device has been placed.
5. The current and voltage connectors are designed for cables up to 2.5 mm
2
, but
can accept cables up to 4 mm
2
Excessive force can damage the device. The thumbscrews only need to be fingertight to hold the device in place.
Note: For 3 phase with neutral connection (Figure1) the neutral must be connected;
otherwise the device will not function.

1- Measurements of parameters given in the parameter table can be displayed
on LCD screen.
2- Current and voltage transformer ratios can be programmed.
3- Parameters in 3 phase with neutral, 3 phase without neutral and Aron
connection systems can be measured
4- The existence of 3 phases can be displayed as VL1 ,VL2 ,VL3 on the
right corner of the device at any time.
5- Unauthorized access to the devices settings can be prevented by setting
up a password from the Setup Menu.
FEATURES
GENERAL INFORMATION
Device, based on DSP(Digital Signal Processor), is designed for the purpose of
measuring all parameters in industry plants. The measured parameters can be
displayed on LCD screen which has dimension of 3.6 inch and can be read easily
in dark environments by activating the Back-Light function.

CT (Current transformer ratio) :
The current transformer ratio is set in this menu. It can be programmed
between 1...5000
Note: If Tot menu is selected, device measures the reactive powers of three
phases. If total phase value is inductive, it records values to the inductive area.
If total phase value is capacitive, it records values to the reactive area.
If Sprt menu is selected, device measures the reactive powers of three phases
for each phase seperately. If phase value is in the inductive area, it records values
to the inductive reactive area. If phase values is in the capacitive area, it records
values to the capacitive reactive area. Measurement for each phase seperately
can be done for 3P4W (3 Phase with Neutral) systems.

(LCD Display Settings)
In this menu, LCD display settings are configured. It has 3 sub-menus.
Loop: ... , Cont: ... , BL: ...
Loop:
In this menu, the duration of displaying instantaneous value is adjusted automatically,
while in the Instantaneous Values menu. The Loop duration can be adjusted between
1... 600 in terms of seconds.
For example;
The Loop duration is set 10sec. In the Instantaneous Values menu, if any button
is not pressed during 10 sec, the Instantaneous values are displayed in sequence
for 10 seconds periods.
By using this function all instantaneous values can be observed one after the other
without pressing any buttons.
This function can be cancelled by selecting No option in the Loop Menu.
By scrolling with (UP), (DOWN) buttons while in the Instantaneous Values
Menu, you can observe the below parameters of the network one after the other.
Observing the Measured Parameters
Observing the Instantaneous Values
In this menu, instantaneous values of parameters are displayed.
This menu is the last menu that is reached by pressing ESC button while in any
menu.
Instantaneous Values menu is the main menu of device. If you wait a while without
pressing any buttons in any menu, the Instantaneous value menu automatically
comes back.
When a device is energized for the first time, the device is in the Instantenous values
menu and shows the instantaneous values.
The display is seen as below.
Note:
When ARON connection is choosed, L2 - - - symbol is seen at the
,
