NETWORK ANALYSER
MPR-53/53S
General
MPR-53/53S is developed for measuring all the electrical parameters on the
network. Measured parameters are shown in 5 separate displays. his allows
to monitor more than 50 parameters at the same time. MPR-53S has also
MODBUS serial interface feature.
Using of MPR-53/53S:
Parameters are shown in L1, L2, L3 displays (V
LN
; V
LL
; A; I
N
; W; VAr; VA; Cosj;
kWh, kVarh, HD) by using up-down buttons. otal Active (SW), otal Apparent
Power (SVA) and Frequency (Hz) are selected by back button.
otal Reactive Power (SVAr) and Cosj are selected by Esc button.
Monitoring of Min.,Max. and Max. Demand Val es:
Min. and max. values are defined for V
LN
, V
LL
, A, W, VAr, VA, SW, SVAr, SVA;
demand values are defined for A, W, VAr, VA, SW, SVA, SVAr.
If measured instant value is smaller than min. value which was stored before,
it is stored as new min. value. If measured instant value is greater than max.
value which was stored before, it is stored as new max. value.
Demand value is the average value of the measured values in demand time
(15 minute).
If one of defined parameters is displayed (ie. A) when deman button is
pressed min., max or max. demand values are displayed. When an undefined
parameter is displayed (ie. Cosj) if demand button is pressed, instant value
is continued to display.
Monitoring THD Val es
When V
LN
and HD leds light on, voltage HD is monitored and also if A
and HD leds light on, current HD is monitored.
Monitoring Ne tral C rrent
Neutral current can be monitored by scrolling after 3-phases current values
has displayed.
H-L-M LEDs
H-L-M LEDs are dedicated to displaying the min., max. and max. demand
values according to selected parameters.
H: Maximum Value, L: Minimum Value, M: Max. Demand Value
Energy P lse O tp ts
MPR-53/53S has 2 Energy Pulse Outputs. hese outputs give the pulses only
for E-1 (Energy Counter).
P l1 and P l2: In o-1 (Pulse1), o-2 (Pulse2) menus which are in the pulse
menu, device give pulse according to selected energy parameters as [Active
energy (ACt, A-I, A-E), Reactive energy (rEA, r-L, r-C)].
Please refer to the pulse menu for the coefficients of energies.
In this menu, current transformer ratio is set between 1 - 2000.
C rrent Transformer Ratio Set p
Note: If the current transformer is not used between the system
and MPR-53/53S, current transformer ratio is entered as 1.
Example: If a current transformer which has a ratio of 250/5A is
used between the system and MPR-53/53S; Current transformer
ratio is entered as 50 (250/5).
Press SE button for 3 seconds (trA Fo menu is displayed)
Press ESC button one by one until SAU E SEt yES is displayed.
Press SE button. When SAU E SEt yES is displayed, if you
press ESC button or choose no option instead of yES option
by using UP-DOWN buttons, new data will be cancelled and
previous value will be activated.

Press SE button. Blinking the first digit of displayed value appears.
(trA Fo Utr menu can be programmed similarly.)
Digital Inp ts
MPR-53/53S has 2 digital inputs which are used to monitor the status of
electrical contacts. Digital input has 2 functions :
- Enabling remote control of the data received through the digital input terminal
(battery, thermostat, circuit breaker, pumps status)
- Controlling energy counters and determining which energy counter will be
active.
FUNCTIONS OF BUTTONS
In the monitoring mode, it is used to switch between
(V
LN
, V
LL
, A, W, VAr, VA, Cosj, kWh, kVarh, HD) parameters.
At the programming mode, it provides to increase value of desired
parameter and pass to the next menu.
(Back) In the monitoring mode, it is used to switch between SW, SVA
and Hz parameters. It used to switch to the previous digit in submenu.
In the monitoring mode, it is used to pass between
(V
LN
, V
LL
, A, W, VAr, VA, Cosj, kWh, kVarh, HD) parameters.
At the programming mode, it provides to decrease value of desired
parameter and pass to the prevides menu.
(SE ) In the monitoring mode, it is used to switch between min.,
max., demand and instant values. When it is pressed for 3 seconds,
programming mode it is entered.
In the programming mode, it is used for saving parameters and
moving to the sub menu.
(ESC) In the monitoring mode, it provides to switch between SVAr
and Cosj values. In the programming mode, it is used to enter to
the upper menu or it is used to quit from the programming mode
without saving values.
If ser password is activated and set b tton is pressed for 3
seconds, a pin code is req ired in order to enter to the men .
Press SE button; trA Fo Ctr menu is displayed (In C -25 adapted
devices, trA Fo trn is displayed instead.)
(Not: trA Fo Utr menu can be displayed by scrolling the UP/DOWN
buttons.)
Enter the blinking digit value by scrolling UP/DOWN buttons.
Switch to the other digits by using SE button, use BACK button
to go to previous digit. After you entered the last digit press SE
button, trA Fo Ctr / trA Fo trn / trA Fo Utr is displayed. on
can be selected by scrolling UP/DOWN buttons.

Calc lation Methods for Active / Reactive Power Val es
If the led on the most left side blinks it represents that active powers / reactive
powers direction is negative.
here are two methods for calculating total active and total reactive powers:
1) Active / Reactive power can be calculated by summing import and export
values and displaying as a single value.
2) Active / Reactive power can be calculated according to direction as
import / export.
Note :
1) The dot at the most right digit of the fo rth display (D ring SW is
displayed) represents that displayed val e is export active power val e.
Vice versa, displayed val e is import active power val e.
2) The dot at the most right digit of the fo rth display (D ring SVAr is
displayed) represents that displayed val e is capacitive reactive power
val e. Vice versa, displayed val e is ind ctive reactive power val e.
3) The displayed parameter will not change if power is off after 30 seconds
of stand-by (ie. A).
