1. Prepare a place for mounting on the control panel (see Figure).
2. Install the gasket on the frame of the device to ensure degree of protection IP54.
3. Insert the device into a specially prepared hole on the front of the control panel.
4. Insert the supplied retainers into holes on the sides of the device.
5. Tighten supplied screws M4 x 35 in the holes of each retainer so that the device is pressed firmly to the front of the control panel.

To ensure the reliability of electrical connections it is recommended to use copper multicore cables, the ends of which should be carefully cleaned, tinned, otherwise use cable lugs before connection. Stripping of conductors must be performed in such way that the stripped ends after connecting to the device do not protrude beyond the terminal block. Cable cross section should be no more than 1 mm².

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 screened. Special cables with shielding or grounded steel pipes of suitable diameter can be used as screens. 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.
• It is necessary to install spark-suppression filters in the lines of switching of power equipment.

When mounting the system in which the device is used, the rules for effective grounding should be taken into account:

• 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.

Caution

After unpacking the device, make sure that it has not been damaged during transportation.

If the device has been for a long time at a temperature below minus 20 °C, it is necessary to keep it in a room with a temperature corresponding to the operating range for at least 30 minutes before switching on and operation.

For connecting the device perform following actions:

1. Connect the device to a power source.

   Danger

   Before powering up the device, it is necessary to check the correct connection of the supply voltage and its level.

2. Connect the "device - sensors" communication lines to the sensors and to device inputs.
3. Connect the "device - load" communication lines to the actuators and to outputs of the device.
4. Apply power to the device.
5. Set up the device.
6. Power off the device.

Screw terminals are located on the back wall of the panel-mounting device or inside the device (wall-mounting). The terminal block contacts assignment is shown in Figure.

Danger

Supply voltage on the device inputs (pins 9 – 12 at the terminal block) must be in range from 0 to 24 V.

Notice

To supply the switching devices and sensors to the screw terminal block of the device is provided with supply voltage (pin 13 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 Figures and .

Scheme for connection of passive and active sensors with an output n-p-n open-collector transistor or p-n-p is shown in Figures and accordingly.

Device has a dual switch for selecting, which of the types of sensors will work. It is located on the lateral side of the housing Щ1 and Щ2. For device in the H housing, the switch is located inside the housing (to access the switch, it is necessary to remove the device cover by unscrewing the four screws that fasten the cover to the base). Appearance of the switch is shown in Figure.

Positions of the switch depending on which device operates with different sensors, are shown in Table.

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.

A transistor optocoupler is usually used to control a low-voltage relay (up to 50 V) – see Figure.

Danger

The diode VD1 (KD103 or similar type) should be installed in parallel to the relay coil, in order to avoid failure of the transistor due to the large self-induction current.

The optosimistor is connected to the control circuit of the power triac through the limiting resistor R1 according to the scheme shown in Figure.

Notice

Nominal value of the resistor determines the current of the triac.

Optosimistor can also control a pair of anti-parallel connected thyristors (see Figure).

Danger

It is recommended to connect a filtering circuit (RC) to the terminals of thyristors or triacs in order to prevent breakdown due to high-voltage power surges in the network.

Functional diagram of the device is shown in Figure.

The device has four independent digital inputs for external control signals. To the inputs can be connected:

• switching devices (buttons, switches, reed switches, relays, etc.);

• sensors with output n-p-n-transistor with an open collector;

• sensors with output p-n-p-transistor.

The levels of the input signals are converted and processed in the matching unit and then sent to the digital signal processing unit that performs:

• reassignment of inputs in accordance with the selected counting mode (see section);

• filtering of input signals (see section);

• counting incoming pulses on the device inputs;

• convertion of the value from the counter into real physical value;

• comparing signal value to the setpoint before displaying;

• generation of signals for controlling the outputs according to a specified algorithm.

Control unit includes buttons for entering parameters of the device.

Display unit displays the measurement results or operating parameters on the indicators and shows the counter status using LEDs.

Secondary power supply converts the incoming voltage for all units of the device, depending on the version (with AC or DC power supply), and generates a signal indicating the loss of supply voltage.

The device can be connected with PC using RS-485 and USB interfaces that allow to set and edit the device configuration, monitor its current status and indications.

Elements of indication and control are located on the front panel of the device (see Figures and):

• two seven-segment six-digit digital indicators, red and green – see Table;
• six/eight LEDs (depending on the construction type) – see Table;
• four/five buttons (depending on the construction type) – see Table.

All elements are placed on two (in housings Щ1 and Н) or on three printed circuit boards (in housing Щ2).

During operation, the device counts the number of incoming pulses at its counting input, compares it with setpoint, converts this quantity into a physical value, and displays the value on the indicator. Device can operate in following modes of counting:

• count-up;

• count-down;

• command;

• individual;

• reversing;

• quadrature.

During operation the counter interprets different types of signals. On the device input first incoming pulse is considered as Start signal for counting. Counting stops when the Stop signal (next pulse) comes.

If there is an active "Reset" signal, the number of counted pulses is reset (counting continues from 0).

Block prevents the transmission of the counting pulses to the device input. While this signal is active, counting is blocked.

Danger

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.

Read more about each of the counting modes, see section.

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 50,000 Hz), the second filters signal on the control inputs of the device (from 1 to 999999 microseconds).

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 for at least 2 seconds.For access to configuration setup (parameters of connection with PC) press at the same time buttons and and hold them for 2 sec.

While editing, if no button is pressed within 2 min., device automatically restores previous value of the parameter and returns to parameter view mode. If within 3 minutes there are no actions in Setup menu, device automatically returns to Operation.

When device enters Setup for the first time, upper 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).

Notice

If you forgot your password, Setup mode can be entered with password 1098. When this value is entered, password is reset to 0000. Therefore, it is not recommended to set the new user password as 1098, because in this case, each time the password is entered, its value will be reset to default.

Structure of the device settings menu and sequence of pressing the buttons for setup is shown in figure and figure.

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.

Structure of the RS-485 configuration settings menu and sequence of pressing the buttons for setup is shown in Figure.

Notice

The list of configurable parameters of the device and their possible values is shown in Appendix.

Availiable types of counting (depending on the values of parameter inP) are presented in Table.

Types of counting

Mode	Description
Count-up (inP = 1)	Input functions: Input 1 – count, Input 2 – start/stop, Input 3 – reset, Input 4 – block Operating principle: Pulse count from zero upwards. When the setpoint is reached, the corresponding output is switched and the counter is reset {t1–t2} – blocking signal the counting inputs; t3 – switching of output 2 in case of coincidence of values of the counting register and setpoint 2; {t4–t5} – stop-start signal; t6 – switching of output 1 in case of coincidence of values of the counting register and setpoint 1
Count-down (inP = 2)	Input functions: Input 1 – count, Input 2 – start/stop, Input 3 – reset, Input 4 – block Operating principle: Counting pulseopw6z7ds from the highest by the module setpoint to zero (decreasing). When the zero is reached, corresponding output is switched and the setpoint register is written to the count register {t1–t2} – blocking signal on the counting inputs; t3 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; {t4–t5} – stop-start signal; t6 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1
Command count (inP = 3)	Input functions: Input 1 – count, Input 2 - direction of count, Input 3 – reset, Input 4 – block Operating principle: Two inputs are used: counting pulses are applied to the first, the status of the second determines the direction of the count. If there is a "logical 0" at the second output, the counter increases its value, if there is a "logical 1" it decreases. In this type two setpoints can be set, meanwhile: • if the setpoints have the same sign, counter resets after reaching the setpoint, that is larger by module. {t1–t2} – the decrease in the value of the counting register (impulse appears at the counting input 2); t3 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1 • if the setpoints have different signs, the counter is reset after reaching each value {t1–t3} – the decrease in the value of the counting register (impulse appears at the counting input 2); t2 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1 Notice If the setpoint is set as zero, it is considered to be disabled, and the counter does not use it.
Individual count (inP = 4)	Input functions: Input 1 – count 1, Input 2 – count 2, Input 3 – reset, Input 4 – block Two counting inputs are used: pulses on Input 1 increase the value of the counting register, and the pulses on Input 2 decrease it. In this case, two setpoints are used (after reaching each of them, the corresponding output switches): Operating principle: • if both setpoints have the same sign, counter does not reset after reaching lesser (by module) value. Otherwise, corresponding output is switched each time counter reaches this setpoint, regardless of the direction of the count t1, t3, t5 – moments of the decrease in the value of the counting register (impulse appears at the counting input 2); t.2 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1 • if the setpoints have different signs (the first is greater than zero, and the second is smaller), then counter resets after reaching each setpoints t1, t3 – moments of the decrease in the value of the counting register (the appearance of the pulse at the counting input 2); t2 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1
Reversing count (inP = 5)	Input functions: Input 1 – count 1, Input 2 – change counting direction (reverse), Input 3 – reset, Input 4 – block Operating principle: After the power is on, the device is in the "count-up" mode by default. For reversing count it is necessary to apply signal to input 2. Thus there are two counting inputs: pulses on Input 1, lead to an increase in the value of the counter, the counting direction is changed cyclically with each incoming pulse on Input 2. In this case, two setpoints are used (after reaching each of them, the corresponding output switches): • if both the setpoints have the same sign t1, t2 – moments of change of the counting direction (the appearance of the pulse at the counting input 2); t3 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1 • if the setpoints have different signs t1, t3 – moments of change of the counting direction (the appearance of the pulse at the counting input 2); t2 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1
Quadrature / operation with encoders (inP = 6)	Input functions: Input 1 – count 1, Input 2 – count 2, Input 3 – reset, Input 4 – block Operating principle: The counting direction is determined by the meanders that come on two inputs. If the first meander is ahead of the second one, the counter counts the pulses at the first input in the increase mode, and if it lags – in the decrease mode. In this case, two setpoints are used (after reaching each of them, the corresponding output switches): • if both the setpoints have the same sign t1, t2, t5, t6 – meander at input 1 is ahead of the meander at the input 2, the counter counts in the mode of increasing the value of the count register; t3, t4 – the meander at input 1 lags behind the meander at input 2, the counter counts in the mode of decreasing the value of the counting register; t7 – moment of switching of output 2 for the time of exceeding the value of setpoint 2 by the counting register; t8 – moment of switching of output 1 for the time of exceeding the value of setpoint 1 by the counting register • if setpoints have different signs t1, t2 – the meander at input 1 lags behind the meander at input 2, the counter counts in the mode of increasing the value of the count register; t3 – moment of switching of output 2 in case of coincidence of values of the counting register and the setpoint 2; t4, t5 – the meander at input 1 is ahead of the meander at input 2, the counter counts in the mode of increasing the value of the count register; t6 – moment of switching of output 1 in case of coincidence of values of the counting register and the setpoint 1 Note After reaching the physical limit of the count (if the counter does not reset after reaching the setpoint), the device transfers the overflow result and continues the count.
