Frequently Asked Questions - MPR-16S-21-D ENTES

How do I properly wire the MPR-16S-21-D power factor controller?

Connect voltage inputs (L1, L2, L3) via 3-phase lines and current inputs via external current transformers (CTs). Ensure CT secondary is rated 5A. Refer to the wiring diagram in the manual for correct phase sequence and CT orientation.

Can I use this controller in a single‑phase system?

The MPR-16S-21-D is designed for 3‑phase systems. Using it on single‑phase may produce inaccurate readings. For single‑phase applications, consider a dedicated single‑phase controller.

What is the maximum number of capacitor steps supported?

The controller supports up to 6 steps via its relay outputs. Each step can be programmed independently for size and switching delay.

How do I set the target power factor?

Access the programming menu via the front keypad. Navigate to 'Target PF' and set a value between 0.80 inductive and 0.80 capacitive. The controller will automatically switch capacitor banks to maintain this PF.

What does the 'ALARM' indication mean?

The alarm can indicate over‑voltage, under‑voltage, over‑current, or harmonic distortion exceeding limits. Check the alarm history in the menu; refer to the troubleshooting section of the manual.

Can I connect the controller to a PC or SCADA system?

Yes, if the optional RS‑485 Modbus port is installed. Use the ENTES software or any Modbus master to read real‑time data and adjust settings remotely.

How often should I clean the controller?

Clean the front panel with a soft, dry cloth when dust accumulates. Do not use liquids or abrasive cleaners. Internally, the device is maintenance‑free except for annual wiring checks.

What is the warranty period for this device?

ENTES provides a standard 2‑year warranty from the date of purchase against material and manufacturing defects. Extended warranty options may be available from your distributor.

Can I replace the internal fuse myself?

Yes, the fuse is user‑accessible. Disconnect power, open the terminal cover, and replace the 5x20mm fuse (rating 0.5A/250V) with an identical type. Use only ENTES‑approved fuses.

Where can I download the full user manual?

The manual is available for free on notice‑facile.com in PDF format. Search for 'ENTES MPR-16S-21-D' and click 'Download'. You may also request a translation via email.

Applications

This is a MPR-1 series 3-phase mains analyzer. It is a microprocessor based device which is designed for measuring all parameters of an electricity main; calculate consumptions and transferring desired parameters with Modbus and I/O outputs.

Thanks to the RTC clock chip and flash memory of the device, the operations performed by the operator such as interruption records, time and setting changes, reset operations are recorded in real time. These records can be remotely read and monitored with Modbus RTU protocol over RS-485 communication line.

The current connection is made by connecting it to a 1A or 5A secondary current transformer.

MPR-1 Product Family

Appearance and Interface

The appearance of the device's front is as below:

Terminal Structures

The terminal structures according to the models are described in this section:

Structure of the MPR-14S 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 95-270 VAC/DC (12-50 VDC for MPR-1X-D series) supply connection through these terminals.

Voltage Terminals: N, L1, L2, L3

Please, apply 3-phase voltage connection through these terminals.

Communication Terminals: A(+), B(-), GND, TR

RS-485 communication terminals are used for Modbus RTU communication connection. A (+) and B (-) terminals are connected in parallel between devices.

When the communication distance exceeds 10 meters and there are more than one device on the line, communication instability may occur. In this case;

• A 120 Ohm connection resistor from the device box is installed between the A (+) terminal and the B (-) terminal,
• Short circuit between the TR terminal and the A (+) terminal.

In this way, line balancing is done.

Structure of the MPR-15S-22 Terminal:

DOC terminals is referred to digital output common, digital output reference connection is done with this terminal.DO1 and DO2 is also referred to 1st and 2nd digital output terminals.

INC terminal is referred to Input Common and it is the digital input reference. IN1 and IN2 are also referred 1st and 2nd digital input 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 5-30V. Inputs have 1kV insulation level.

Digital Output Terminals: OC, O1, O2

As the OC terminal will be the joint point (reference), the O1 and O2 terminals are used 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.

Structure of the MPR-16S-21 Terminal:

Different from the MPR-16S-21'den 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 MPR16S-21 model is as in the following:

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 5-30V. Inputs have 1kV insulation level.

Structure of the MPR-17S-23 Terminal:

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.

Analog Output Terminals: AOC, AVO, AIO

AOC terminal is the common point (reference), and analog current or voltage output is provided from the AIO and AVO terminals, respectively. Only one of the AVO and AIO terminals is used at the same time.

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 5-30V. Inputs have 1kV insulation level.

Digital Output Terminals: OC, O1, O2

As the OC terminal will be the joint point (reference), the O1 and O2 terminals are used 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.

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.

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.

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 connection 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.

Communication Line Termination Resistance

RS-485 communication terminals are used for Modbus RTU communication connection. A (+) and B (-) terminals are connected in parallel between devices. When the communication distance exceeds 10 meters and there are more than one device on the line, communication instability may occur. In this case;

• 120 Ohm line coming out of the device box between A (+) terminal and B (-) terminal. termination resistor installed,
• Short circuit between the TR terminal and the A (+) terminal.
  In this way, line balancing is done.

Device Communication Settings

Device communication address and baud rate settings are adjustable from the DIP switches located at the device's front panel. Devices communication address settings can be done, as shown at the below table.
