## Electrical connection

<a id="topic-5560"></a>

### Wiring recommendations

To ensure the reliability of electrical connections it is recommended to use copper stranded cables, the ends of which should be carefully cleaned and tinned. Otherwise use cable lugs before connection. Cable conductors should be stripped so that their bare ends do not protrude beyond the terminal strip after connecting to the device. The cable cross section must be not more than 1 mm<sup>2</sup>.

General requirements for connection lines:

- During the cabling, communication lines that connect the Device with sensors must be isolated to a separate circuit (or several circuits) and placed separately from power cables or other sources of high-frequency and impulse interferences;
- To protect the Device inputs from the effects of industrial electromagnetic interference, the communication lines between Device and sensors should be shielded. Special cables with shielding or grounded steel pipes of suitable diameter can be used. The cable shielding should be connected to the functional ground terminal (FE) in the control panel;
- Network interference filters should be installed in the power supply lines;
- Spark-fighting filters should be installed in the switching lines of power equipment.

When installing the system in which the Device operates, you should follow the rules for effective grounding:

- all grounding lines must be laid in Y-connected circuit, ensuring good contact with the grounding element;
- all earthing circuits must be made with wires of the largest possible cross-section;
- it is forbidden to connect the device terminal "Common" with grounding lines.

<a id="topic-5561"></a>

### Getting Started

> [!CAUTION]
> **Danger.** After unpacking the device, make sure that it has not been damaged during transportation.

If the Device was kept for a long time at a temperature below minus 20 °С, then before turning it on and starting work, it should be kept in a room with a temperature corresponding to the operating range for 30 minutes.

To connect Device:

1. Connect the Device to a power source.

   > **Caution.** Before applying power to the Device, check that the supply voltage and its level are correct.

2. Connect primary transducers to the Device inputs.

3. Connect actuators to the Device outputs.

4. Apply power to the Device.

5. Set up the Device.

6. Power off the Device.

<a id="topic-5562"></a>

<a id="НазначениеКонтактовКлеммника-28AFF5E1"></a>

![Контакты клеммника en](https://docs.owen.ru/book_img/120/18775EN.png)

*Pin assignment*

> [!WARNING]
> **Caution.** If the device is powered from a DC voltage network, then terminals 3 and 4 of the screw terminal block must be interconnected by a jumper.

<a id="topic-5563"></a>

### Connection of switching devices and sensors

> [!WARNING]
> **Caution.** Inputs of the Device (pins 9 – 12 at the terminal block) support supply voltage from 0 to 24 V. Any voltage out of this range is prohibited.

> [!IMPORTANT]
> **Notice.** To supply switching devices and sensors to the screw terminal block of the device, the supply voltage is derived (pins 13 and 14 of the terminal block). If power consumption of input exceeds the load capacity of the built-in power supply (24 V), then an external power supply with an output voltage of 12 to 34 V (24 V recommended) must be used for powering.

Scheme for connection of the switching devices to the inputs is shown in [Figure](#ПодключениеКоммутационныхУстройствА-2913625E).

<a id="topic-5564"></a>

### Connecting load to the outputs

Outputs can be made in the form of electromagnetic relays (P), transistor (K) or triac (C) optocouplers. The outputs are used for direct load control (on/off) or for control by more powerful elements: contactors, solid state relays, thyristors or triacs. The outputs are galvanically isolated from the circuit of the Device.

Scheme of connecting the load to the electromagnetic relay is shown in [Figure](#СхемаПодключенияНагрузкиКВУТипаР-29138F73).

<a id="СхемаПодключенияНагрузкиКВУТипаР-29138F73"></a>

![нагр к ВУ Р en](https://docs.owen.ru/book_img/120/18771EN.png)

*Scheme of connecting load to the output of type Р*

A transistor optocoupler is usually used to control a low-voltage relay (up to 50 V), see [Figure](#СхемаПодключенияНагрузкиКВУТипаК-29139189).

> [!WARNING]
> **Caution.** In order to avoid failure of the transistor due to the large self-induction current, it is necessary to install a VD1 diode (KD103 or similar type) in parallel to the relay coil.

<a id="topic-5568"></a>

### Switch on and operation

During operation (see [Figure](#ДиаграммаРаботыПрибора-2993FD55)), the Device counts the number of pulses arriving at its **counting** input (input 1), converts this quantity into a physical value, and displays the value on the indicator.

The counter of the Device operates in the mode of direct counting (counting of pulses from zero upward). If the maximum counting value (999999) is exceeded, the number of counted pulses is reset and the counter continues counting.

The logic of the counter on the **start/stop** signal (input 2) is as follows:

- the first impulse (starting) comes to this input and enables the counting;
- when the next (stop) pulse arrives, the counting stops.

If there is an active **Reset** signal (input 3), the number of counted pulses is reset.

**Block** (input 4) prevents the transmission of the counting pulses to the Device input. While this signal is active, counting is blocked.

> [!WARNING]
> **Caution.** The setpoint is specified with the same accuracy as for counting physical values. The multiplier can be set from 0.00001 to 99999. The conversion of counting results (result of multiplying) will be rounded up.

The counter also **filters** the input signals with two filters. The first one filters the signal on the counting input by pulse duration (from 1 to 2500 Hz), the second filters signal on the control inputs of the Device (from 200 to 999999 μs).

## Setup

<a id="topic-5570"></a>

### Sequence of setup

The Setup mode is intended for viewing and editing the device parameters. New parameters are saved to non-volatile memory of the device.

To enter (or exit) the Setup mode, press and hold button![Кнопка Прог](https://docs.owen.ru/book_img/120/5568.png) for at least 2 seconds.

While editing, if no button is pressed within 2 min., device automatically returns to parameter view mode.

When device enters Setup for the first time, indicator shows `PASS`. Enter a new 4-digit password (default is **0000** ), save it and memorise. This password is further required for changing the device settings and for restoring factory settings (`dEFAUL`).

> [!IMPORTANT]
> **Notice.** If you forgot your password, Setup mode can be entered with password **1098**.

Structure of the device settings menu and sequence of pressing the buttons for setup is shown in [Figure](#МенюНастроекПрибора-29BB3EF2).

<a id="МенюНастроекПрибора-29BB3EF2"></a>

![параметры рис А6 prag en](https://docs.owen.ru/book_img/120/18790EN.png)

*Device settings menu*

Since the **FDP** and **DP** parameters set restrictions on each other (the number of displayed digits after the decimal point in the counting results can not be larger than the number of digits after the decimal point of the entered multiplier), editing of parameters **FDP**, **DP**, **F** should be performed in the following sequence:

- to increase the number of displayed digits after the decimal point (decimal point offset to the left):

  - set parameter **FDP**;
  - set parameter **F**;
  - set parameter **DP**.

- to decrease the number of displayed digits after the decimal point (decimal point offset to the right):

  - set parameter **DP**.
  - set parameter **FDP**;
  - set parameter **F**.

Due to the restrictions imposed by the Dispenser mode (`oUt`= **2**), it is recommended to change the mode of operation of the control unit in the following sequence:

- set parameter **SPM**;
- set parameter **rSt**;
- set parameter **oUt**.

> [!IMPORTANT]
> **Notice.** The list of configurable parameters of the device and their possible values is shown in [Appendix A](#topic-5579).
