5 Connection
5.1 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 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 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.

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 the 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. Apply power to the device.
4. Set up the device.
5. Make a test run of the device algorithm to verify that the settings are correct.
6. Power off the device.
7. Connect operating mechanisms to the device outputs.
20
5.3 Terminal block contacts assignments
Screw terminals are located on the back wall (panel-mounting) or inside the device (wall-mounting). The
terminal block contacts assignment is shown in Figure 5.1.
Figure 5.1 - Terminal block contacts assignments
5.4 Connection of switching devices and sensors
CAUTION
Do not apply voltage to the device inputs (pins 9 - 12 of the terminal block) that is outside the
range from 0 to 24 V.
21
NOTICE
Pin 13 is an internal power supply, required for connecting of switching devices and sensors.
If the power consumption of the input devices exceeds the load capacity of the internal power
source (24 V), an external source with an output voltage of 12 to 34 V (recommended 24 V) is
required.
Scheme for connection of the switching devices to the inputs is shown in Figure 5.2.
Figure 5.2 - Connecting switching devices: 1) when the device is operating from an external
power source; 2) when the device is operating from an internal power source
The connection diagrams of passive sensors with an n-p-n-type transistor with an open collector output
are shown in Figure 5.3.
22
Figure 5.3 - Connection of passive sensors with n-p-n-output: 1) when the sensor is operating
from an external power source; 2) when the sensor is operating from an internal power source
5.5 Connecting load to the outputs
The device may not have outputs, have one analog or digital output or two outputs, one of which is
analog, and the second is digital.
23
CAUTION
The outputs are galvanically isolated from the circuit of the device.
It is possible to use an internal 24 V power supply to power the output, which is used to power active
sensors.
5.5.1 Analog outputs
The analog output can operate as a DAC in two modes: “parameter-current” (И) or “parameter-voltage”
(У).
For normal operation of devices with an analog output of type И, the DAC must be powered from an
independent DC source that provides galvanic isolation of the device’s electrical circuit and “connected
mechanisms”. The voltage of the power source is calculated by the formulas:
UPSmin UPS UPSmax
UPSmin ¼ 7:5 þ IDACmax Rload
UPSmax ¼ UPSmin þ 2:5
where UPS is voltage of the power source, V;
UPS min is the minimum allowable voltage of the power source, V;
UPS max is the maximum allowable voltage of the power source, V;
IDAC max is the maximum allowable current of DAC, mA;
Rload is load resistance of DAC, kΩ.
24
CAUTION
The USP value must be included in the allowable range of the supply voltage (from 10 to 36 V).
If for any reason the voltage of the DAC power supply exceeds the calculated value USP max, then the
limiting resistor should be connected in series with the load, the resistance of which is calculated by the
formulas:
Rlimitmin < Rlimitnominal < Rlimitmax
Rlimitmin ¼UPS UPSmax
IDACmax
Rlimitmax ¼UPS UPSmin
IDACmax
where Rlimit nominal is nominal value of the limiting resistor, kΩ;
Rlimit min is minimum permissible value of the limiting resistor, kΩ;
Rlimit max is maximum permissible value of the limiting resistor, kΩ;
IDAC max is the maximum allowable current of DAC, mA;
UPS is voltage of the source used to power the DAC, V.
An example of the connection to the output of type И with a power source and load is presented in
Figure 5.4.
25
Figure 5.4 - Wiring of output of type И
An example of connection to the output of type У is shown in Figure 5.5.
Figure 5.5 - Wiring of output of type У
CAUTION
The load resistance Rload connected to the DAC must be at least 2 kΩ.
The voltage of the output power source should be not more than 30 V.
26
5.5.2 Digital output
The digital output is an electromagnetic relay (type P) (see Figure 5.6). This output is used to control the
load (on / off) directly or through more powerful control elements, such as starters, solid state relays.
Figure 5.6 - Output wiring
27
6 Operation
6.1 Principle of operation
Functional diagram of the device is shown in Figure 6.1.
Figure 6.1 - Device operation
The device has two digital inputs for connecting sensors (pulse counter and operating time counter). To
the inputs of the device can be connected:
• sensors with output n-p-n-transistor with an open collector;
28
• sensors with a dry contact type output (reed switches).
The counting input of the device receives pulses from a sensor that controls one or more marks on the
motor shaft.
The levels of the input signals are converted and processed in the matching unit, after which they are
sent to the digital processing unit, where it occurs:
• filtering of input signals;
• measuring the instantaneous value of the shaft speed;
• measurement of operating time at the operating time counter;
• conversion of measured values into real physical quantities;
• scaling of values before their output to the display;
• generation of signals for controlling the outputs according to a specified algorithm.
NOTICE
The parameter-current/voltage conversion is carried out using the built-in output of a ten-digit
DAC. The signals obtained after the conversion can be used to register parameters.
Control unit includes buttons for entering parameters and controlling the operation of the device.
Display unit displays the measurement results or operating parameters on the indicators and shows
the device status using LEDs.
Internal power supply, depending on the version of the device (with AC or DC power), converts the
supply voltage for all units of the device and generates a signal indicating the loss of supply voltage. It
also generates a DC voltage to power the sensors connected to the inputs of the device.
Using the RS-485 interface, the device is connected to a PC, which makes it possible to set and edit the
configuration of the device, to monitor its current status and readings.
29
6.2 Control and indication
Elements of indication and control are located on the front panel of the device (see Figures 6.2 and 6.3):
• seven-segment six-digit display;
• five LEDs;
• four buttons.

6.3 Switch on and operation
The device can perform following functions:
• tachometer;
• operating time counter.
The signals arriving at the counting input of the device are filtered. The filter is characterized by the
minimum allowable pulse and pause lengths (minImp parameter, ms). All pulses and pauses less than
the specified duration are perceived as bounce and ignored.
The recommended value for this parameter is calculated as follows:
where MaxFreqRele is the maximum frequency (up to 100 Hz) of switching a dry contact relay.
For input frequencies greater than 100 Hz, set minImp = 10 μs.
The principle of operation of this parameter is shown in Figure 6.4:
• 1: pulse duration and pause duration greater than minImp - the signal is passed through the
bounce protection system;
33
• 2: the pulse duration is less than minImp - the signal is not passed by the bounce protection
system;
• 3: the pulse duration is greater than minImp, but the pause duration is shorter than minImp - the
signal is not skipped by the chatter protection system.
Figure 6.4 - Parameter «minImp»
6.3.1 Tachometer mode
When performing the function of a tachometer:
• device measures the instantaneous value of the duration of the time intervals (T) between the
leading or trailing edges (in s);
• device calculates the value of N / T, where N is the value determined by the dimension of the
display of the measured value;
• device displays the obtained value taking into account the scaling factor.
34
The tachometer measurement interval is set by the dttA parameter in:
• rps (N = 1);
• rpm (N = 60);
• rph (N = 3600)
• custom values (N = F × 10-FdP, where F and FdP are variable parameters).
If F × 10-FdP < 1, the values dependent on dttA (FrEQ, UdAC, dPro, LOR, HIR, UdO, dU) can be less
than 1 (for example, 0.25) and displayed on the display as 0. This occurs because fractional display is
not supported. But in the operation of the device, values with a fractional part will be used.
The dttA value affects the upper and lower limits of the FrEQ parameter. That is, the limits are
recalculated in accordance with the coefficient N. For example, the values of the FrEQ parameter lie in
the range [1; 2500]. With the coefficient N = 60, the boundaries of the FrEQ parameter will be as
follows:
• lower limit: 1 × 60 = 60;
• upper limit: 2500 × 60 = 150000.
Counting results are shown on the display. Calculation units are displayed in the form of highlighting of
single LEDs (see Table 6.2 for details).
NOTICE
1. Rounding of the measurement results is carried out in a standard mathematical way, in a
big way. That is, if in a rounded digit a digit is more than or equal to 5, then one is
transferred to the next digit. If the measured value lies within 0.2 ... 0.5 Hz inclusively,
then a value of 1 is transmitted via Modbus to indicate the presence of a signal.
2. If the digit capacity is not enough to display the selected number of digits after the
decimal point, the device automatically shifts the number to the right.
35
An eighth-order moving average filter is used to damp the signal in the device. The MAV.L parameter
defines the minimum time (in seconds) for filling the filter buffer. Adding a new value to the buffer will be
done not earlier than in (MAV.L / 8) seconds. At input frequencies less than or equal to (8 /MAV.L), the
settling time of the input signal to the digital signal can be longer than MAV. L. By default, this filter is
enabled.
6.3.2 Operating time counter
The device counts the operating time if the signal level on the operating time counter reaches a logical
1. When the device performs this function, the LED lights up.
To see the current operating time on display, press and hold the button
. If you release this button, the
display returns to the tachometer reading.
The measured operating time is shown on the display (see Table 6.1 for details). If the current range is
exceeded, the device automatically sets the next display range of the measurement results. The
maximum value of the operating time takes values from 1 s to 9999 days 23 hours.
For devices with discrete output, it is possible to set the limit values of the operating time, upon reaching
which the output is switched on.
36

7.3 Output settings
Device digital output (type P) functions as a comparison device (comparator).
The input value of the comparison device:
• tachometer measurement result (SrcC = tACHo) - control mode is selected using the oUtdo
parameter;
• measured value of the operating time (SrcC = LiFE_T) - the output is switched on when the
setpoint is reached to control the digital output for the operating time UdAY, UHour, UMin, USEc.
When the output is turned on, the ВЫХ LED lights up.
It is possible to work according to one of the following types of logic (see Figures 7.6 and 7.7):
• reverse hysteresis (oUtdo = 1) - output turns on at values Fcurrent > (U+Δ) and turns off at values
Fcurrent < (U-Δ);
• direct hysteresis (oUtdo = 2) - output turns on at values Fcurrent < (U-Δ) and turns off at values
Fcurrent > (U+Δ);
• П-shaped logic (oUtdo = 3) - output is turned on at values (U-Δ) < Fcurrent < (U+Δ);
• U-shaped logic (oUtdo = 4) - output is turned on with the values Fcurrent < (U-Δ) and Fcurrent > (U +
Δ).

Figure 7.6 - Types of logic (reverse and direct hysteresis) when the output operates as a
comparator
44
Figure 7.7 - Types of logic (П- and U-shaped) when the outputs operates as a comparator
NOTICE
1. With П- or U-shaped logic, to suppress bounce during switching, there is an additional
hysteresis of operation of 5 % of the range between the limits (2Δ) (see Figure 7.7).
2. When the pulse repetition rate at the counting input is more than FrEQ, the value equal
to the value calculated for FrEQ is set at the output.
Recommendations for setting the output:
• set oFFdo = 0 and oUtdo = 0;
45
• specify values in Udo and dU. It is recommended that Udo, dU, the upper and lower limits do not
go beyond 0 and FrEQ;
• set the desired output logic (oUtdo).
Digital output control is disabled when oUtdo = 0. The output status is set using the oFFdo parameter.
Analog output of the device (types И, У) functions as a П-controller and a recorder. The operation
mode of the analog output is set using the oUtdAC parameter.
When the output operates as a П-controller, the current value of the measured value is compared with
the preset setpoint (UdAC parameter) and the output signal is from 4 to 20 mA (for type И) or 0 to 10 V
(for type У) proportional to the deviation. The direct proportionality zone is set by the parameter Δ
(dPro). The output signal is generated in accordance with the regulator characteristic set in the oUtdAC
parameter, either in direct proportion (1) or inversely proportional (2) regulation law. Graphs explaining
the principle of forming the control current and voltage of the П-controller for both characteristics are
shown in the Figures 7.8 and 7.9.
Figure 7.8 - Generating of the output signal in the П-controller mode (output of type И)
46
Figure 7.9 - Generating of the output signal in the U-controller mode (output of type У)
When the output works as a recorder (oUtdAC = 3), the following occurs:
• comparing the measured value with the set values of the lower limit of the recording range and the
value of the entire recording range;
• issuing an analog signal to the corresponding output in the form of a current from 4 to 20 mA (for
output type И) or voltage from 0 to 10 V (for output type У), which can be fed to a recorder or other
recording device.
The principle of generating the output signal is shown in Figures 7.10 and 7.11. When the output is
working as a recorder, the lower and upper limits of registration should be set in the Lor and Hir
parameters.
NOTICE
When the measured value goes beyond the recording range, the error level is set at the output:
20.2 mA (for type И output), more than 10.5 V (for type У output).
When oUtdAC = 0, the operation control of the analog output is disabled. The output status is set by
oFFdAC parameter.

8 Maintenance
8.1 Maintenance
Safety measures (see Section 3) should be observed during the maintenance.
Maintenance of the device has to be carried out at least once in 6 months and includes the following
procedures:
• checking the mounting of the device;
• checking the screw connections;
• removing dust and dirt from the terminal board of the device.
8.2 Calibration
Calibration is intended to restore the metrological characteristics of the device in case of their change
after prolonged use or repair work and consists in selecting the minimum and maximum values of the
output signal.
CAUTION
Calibration of the device should be carried out only by qualified specialists of metrological
services.
Calibration is carried out only for analog outputs. To do this:
• connect the load (Rload) and a voltmeter to the output according to Figures 8.1(for output of type У)
and 8.2 (for output of type И);
• apply power to the device.
50
NOTICE
As Rload, you can use the resistance box P4831 or similar with an accuracy class of not more
than 0.05, and as a voltmeter, a device with an accuracy class of not more than 0.05, for
example, B1-12.
0 is displayed - the device is in operating mode.
Figure 8.1 - Calibration of output voltage values
Figure 8.2 - Calibration of output current values
51
The calibration algorithm for analog output:
1. By changing the DAC code and controlling the current (voltage) at the output of the analog
device, to achieve the value of the output signal corresponding to the lower limit of the output
current or voltage (in general, 4 mA or 0 V).
2. Commit the current DAC code as the lower desired limit of the signal at the output of the analog
device.
3. By changing the DAC code and controlling the current (voltage) at the output of the analog
device, to achieve the value of the output signal corresponding to the upper desired limit of the
output current or voltage (in the general case, 20 mA or 10 V).
4. Commit the current DAC code as the upper desired current limit at the output of the analog
device.
5. Set APPLY parameter to YES.
6. Exit the calibration menu.
NOTICE
To apply the calibration parameters, you need to edit both LdAC and HdAC.
Calibration can be carried out using the service menu of the device or via the RS-485 network.
The commands used when calibration over the RS-485 network are given in Appendix A (section
“Calibration”).
Set the LdAC and HdAC parameters to achieve that the value of the output signal corresponds to a
lower or upper desired limit of the output current (voltage). The first submission of these commands is
considered the implementation of paragraphs 2 and 4 of the calibration algorithm, respectively.
