Entes MPR-53S Manual

Entes MPR-53 is a network analyzer that allows the measurement of different electrical parameters in a network, such as voltage (including THD), current, active power (including demand), reactive power and apparent power. It also provides information about energy consumption, harmonics and power factor. The device comes with a backlit LCD display that shows all the measured parameters and it is possible to choose which units to display. It is also possible to connect the device to a computer via a serial interface to transfer the measured data.

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.This allows to monitor more than 50 parameters at the same time. MPR-53S has also

MODBUS serial interface feature.

;

Digital Inputs

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.

Energy Pulse Outputs

MPR-53/53S has 2 Energy Pulse Outputs. These outputs give the pulses only for E-1 (Energy Counter).

Pul1 and Pul2: 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.

Monitoring of Min.,Max. and Max. Demand Values:

Min. and max. values are defined for V

, V

, A, W, VAr, VA, S W, demand values are defined for A, W, VAr, VA, S W, S VA, S VAr

S VAr, S VA

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. Cos is continued to display.

j ) if demand button is pressed, instant value

Monitoring THD Values

When V

and THD leds light on, voltage THD is monitored and also if A and THD leds light on, current THD is monitored.

Monitoring Neutral Current

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

Calculation Methods for Active / Reactive Power Values

If the led on the most left side blinks it represents that active powers / reactive powers direction is negative.

There 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 fourth display (During S W is displayed) represents that displayed value is export active power value.

Vice versa, displayed value is import active power value.

2) The dot at the most right digit of the fourth display (During S VAr is displayed) represents that displayed value is capacitive reactive power value. Vice versa, displayed value is inductive reactive power value.

3) The displayed parameter will not change if power is off after 30 seconds of stand-by (ie. A).

The T times corresponds to a time in which data must not be exchanged on the communication bus to allow the connected devices to recognize the end of one message and the beginning of another. This time must be at least 3.5 characters at the selected baud rate. Adress range (1-247 ) is address of the connected device. The data field contains data sent to the slave by master or data sent to master by slave.

ERROR CODES (Available only for MPR-53S)

Slave device (MPR-53S) sends error message when receive any missing query.

Error codes are given below.

01 Invalid Function: If any message except given above is used, then 01 error messages will be sent.

02 Invalid Register: Error 02 will be send when a reading of a register is requested, except the registers which mentioned in table.

03 Invalid data: If any different value is been set for dedicated Transformer values and nonzero for demand value, then error message 03 will be sent.
