3.2 OPERATING PRINCIPLE AND INPUT SIGNAL PROCESSING
3.2.1 Operating principle
In course of its operation, TR-101 performs input sensors scanning, then, based on the data obtained,

- 5 -
NOVATEK-ELECTRO TR-101
calculates the current temperature value and outputs it on the digital display and sends Control signals to
the corresponding channel relay.
3.2.2 Input signal processing
The signal that is received from sensor is transformed into a temperature digital value.
In order to eliminate the initial input signal processing error, as well as errors that are produced by the
connection wiring; the device measured value can be adjusted. TR-101 provides for two adjustment types,
which allow performing a gain shift or sloping by a specified degree for each channel independently.
3.2.3 Measurements adjustment
3.2.3.1 To provide for the error compensation ΔR = (R0 - R0.TC) produced by the input wiring resistance
RTC, each measured temperature value (Tизм) is added with a user specified value δ. Figure 3.3 shows
an example of a characteristics shift for Pt100 sensor.
Programmable parameters: , , , .
3.2.3.2 To provide for sensor error compensation upon W100 value deviation from the rated value each
Tизм parameter measured value is multiplied by the user set adjustment parameter α.
The ratio boundaries are set within 0,50 to 2,00 limits.
Figure 3.4 shows an example of the characteristic slant variation for Pt100 sensor.
Programmable parameters: , , , .
Figure 3.3 Figure 3.4
3.2.4 Digital filter
To provide for the input signal properties improvement the device employs digital filters that allow
reducing the random interference effect on the temperature measurement.
Programmable parameters:
- digital filter band , , , ;
- digital filter time constant , , , .
The filters are set for each input independently.
3.2.4.1 The digital filter band allows protecting the measurement route from single interference and is set
in ºС. If the measured value Tизм is different from the previous Tизм–1 by the value larger than
parameter value, the device assigns to it a value equal to (Tизм + ) (Figure 3.5). Thus the characteristic
is smoothed out.
As seen in Figure 3.5, smaller band width of the filter leads to slowing down the device reaction to
temperature change. That is why in case of low interference level or during operation with discontinuous
temperatures it is recommended to increase the parameter value or switch off the filter band action by
setting the (, , ) parameter value to 0.
When working under strong interference, in order to eliminate its impact onto the device operation, it is
necessary to reduce the parameter value.
3.2.4.2 The digital filter eliminates the noise signal components by smoothing it exponentially. The main
characteristic of the exponential filter is τф– the digital filter time constant, ( , , )
interval, within which the temperature reaches the 63,2% from measured value Tизм (Figure 3.6).
Reducing τфwill lead to a faster device reaction onto discontinuous temperature variations, but also will

- 6 -
TR-101 NOVATEK-ELECTRO
reduce its protection against interference. Increasing τфvalue increases the device response rate, while
noise is significantly suppressed.
Figure 3.5 Figure 3.6
3.2.5 Two-position regulator (two-position control)
In the two-position control mode the device works according to one of the two logic types, Figure 3.7:
•Logic №1 (heater) is used to control a heater operation (tubular electric heaters, for instance), or to
produce warning that the current temperature value (Ттек) is less than the setting value (Туст). Upon
that the output relay initially closes at values of Ттек < Туст – HS, then opens at Ттек > Туст + HS and
closes again at Ттек < Туст – HS thus effecting the two-position control by Туст setting with the HS
hysteresis.
•Logic №2 (cooler) is used to control a cooler operation (a fan, for instance), or a warning of exceeding
Туст setting value. Upon that the output relay initially is ON at values of Ттек > Туст + HS, then is OFF at
Ттек < Туст and ON again at Ттек > Туст + HS.
If using as compressor cooler recommended define HS in
such a manner to provide the normal (minimum) compressor off time to avoid the device damage.

HS – hysteresis ( , , );

3.2.6 PID- controller (proportional-plus-integral-plus-derivative control)
3.2.6.1 PID control general principles

- 7 -
NOVATEK-ELECTRO TR-101
On the control relay the “controlling” signal Yi is generated; its action is directed at reducing the Ei
deviation.
wherein:
Xp – proportionality band ( - programmable parameter);
Ei– is the difference between the set Туст and current Ттек temperature value, or unbalance;
τд– response speed derivation (programmable parameter “PID-controller derivative constant ” - );
ΔEi– difference between two adjacent measurements Eiand Ei-1;
Δtизм – difference between two adjacent measurements Ттек and Ттек-1;
τи– integration response time (programmable parameter “PID controller integral constant ”);
- derivation cumulative sum.
To provide for the efficient PID controller operation it is important that proper values of Xp, τдand τи
ratios for the given controlled object be set.
Programmable parameters:
[Xp] – ( , , );
[τд]– ( , , );
[τи]– ( , , ).
ATTENTION! Sometimes PID regulation is overmuch or irremissible. In such cases fixing coefficient
τи= 0 or τд= 0 is possible to get PD and PID regulator.
3.2.6.2 Proportional regulator
Proportional regulator is the main where the task of temperature is directly proportional to mistake. Using
only proportional regulator lead to mistake. The low values of proportional regulator lead to lack of stability
and vibration in system but too high lead to low operation.

(or diminish by negative error). The minor constituents of integral element influence to regulator job much.
If the value fixed very high it mean’s the system doesn’t recognize it and will be work with overshoot.

TR-101 NOVATEK-ELECTRO
The regulator speeding lead to incresing overshoot and as a result is lack of stability the system.
Most cases derivative term is fixed neutral or low value to avoid this lack of stability.
Figure 3.10 - Working hours of differential regulator
3.2.6.5 Methods of PID controlling
During the controlling, one of the control methods is selected: “Heater” or “Cooler”.
“Heater” – the output signal value decreases while the controlled temperature grows.
“Cooler” – the output signal value increases while the controlled temperature grows.
Programmable parameters: ( , , ).
ATTENTION!Not recommended using PID control in cooler range of compressor in relation of lack
control the minimal off time compressor can lead to damage device.
3.2.6.6 Action in PID - regulator mode with output key element (pulse-length modulation)
Command current from PID regulator (Yi) is transforming to multiple pulses (picture 3.11) according
following formula:
where :
D– impulse duration (second) ,,,;
Тсл – pulse repetition period (minute) , , , ;
Yi– command current of PID regulator (%).
Figure 3.11 - Diagram act output relay in mode of PID regulation
ATTENTION! The little value of Тсл leads to often commutation and short life power contacts but
The big value of Тсл leads to quality loss regulation.

4 MAINTENANCE AND SAFETY
4.1 SAFETY
Open terminals of the device carry dangerous voltage of up to 250 V. Any connections to the device and
its maintenance operations must be performed only on de-energized device and executive units.
Ingress of moisture to the output terminals and the device inside electronic elements is not allowed. The
use of the device in aggressive environments containing acids, alkali, oils, etc. is prohibited.
The device connection, adjustment and maintenance must be performed only by authorized personnel
that is familiar with this manual.
4.2 MAINTENANCE SCHEDULE
Recommended maintenance schedule – semiannually.
Maintenance scheduled operations consist of visual observation, during which wiring connection to
terminals is checked, frame and casing integrity check for cracking and chipping.
During maintenance operations, the safety precautions listed in chapter 4.1 must be followed.
5 DEVICE CONNECTION
5.1 PERIPHERY CONNECTIONS
5.1.1 General instructions
Prepare cables for connecting the device to sensors, execution mechanisms and peripheral equipment,
as well as to the power supply. To provide for the electric connections reliability it is recommended to use
cables with copper stranded wires, the ends of which should be carefully cleaned and soldered prior to
connecting. The wire core shall be cleared in such way, that its bare ends would not project beyond the
terminals after connection to the device. The cable section must not exceed 2,5 mm2.
5.1.2 Mounting instructions aimed at electromagnetic interference reduction
When laying the “device-sensor” lines, they should be separated into an individual tract (or several
tracts). The tracts shall be placed separately from the power cables, as well as from cables that produce
high frequency and pulse interference.
ATTENTION!The tracts shall be planned in such manner, that the signal lines length is kept minimal.
5.1.3 Mounting instructions aimed at reduction of the power circuit interference
The device shall be connected to 220V 50Hz, circuit feeder that is not connected with supplying power to
heavy-duty industrial equipment. It is recommended installing in the peripheral supply line a feed switch
providing disconnecting the device from the circuit, as well as 1A fuses.
5.2 DEVICE CONNECTION
The device shall be connected in accordance with the diagram on figure 5.1, observing the listed below
sequence:
A) Connect the device to power supply and execution units;
B) connect the “device-sensor” communication lines to the device inputs.
ATTENTION!The device terminals for connecting power circuit and peripheral heavy-duty equipment are
designed for max voltage of 250V. To avoid disruptive electric discharge or insulation arc-over it is
prohibited to connect power sources with higher voltage that one mentioned to the device terminals.
5.3 CONNECTING SENSORS (RTDS)
TR-101 devices employ a three-wire diagram for connecting RTDs (resistance temperature detectors).
Two wires are connected to one of the RTD outputs, and the third wire is connected to the other RTD output
(see figure 5.1). Such diagram, provided that impedance of all three wires is equal, allows to compensate its
impact onto the temperature measurement.
The resistance temperature detectors can be connected to the device under a two-wire diagram as well,
but such arrangement does not provide for the connecting wiring impedance compensation which may lead
to certain dependence of the device measurement from the wires temperature variation.
5.3.1 Connecting sensors (RTDs) according to a two-wire diagram
5.3.1.1 The RTDs (resistance temperature detectors) are connected to the device according to a two-
wire diagram in case when a three-wire diagram cannot be used, for example, whenTR-101 is installed
within units equipped with earlier laid two-wire connection lines.
5.3.1.2 Please, mind that the device readings will depend on the “device-sensor” communication line
wires impedance change, that takes place under influence of the outside air temperature. To compensate

- 10 -
TR-101 NOVATEK-ELECTRO
for the wires parasitic resistance, perform the following:
•Before the operation start install a jumper between contacts 23 and 24 ((26 and 27), (29 and 30), (32
and 33)) of the terminal block, and connect the two-wire line immediately to contacts 22 and 23 ((25 and
26), (28 and 29), (31 and 32)).
•Then connect a resistor box with accuracy rating not less than 0,05 (МСР-63, for example) to the
opposite ends of the “device-sensor” communication line, instead of the thermal element.
•On the resistor box, set the value equal to the RTD resistance at temperature of 0 ºС (50, 100, 500,
1000 Ohms, depending on the sensor type).
•Energize the device and after 20-30 sec, by the digital display readings, define the value of the
temperature deviation from 0 ºС .
•Set the ( , , ) parameter value equal to the temperature deviation value, taken with
the opposite sign.
•Check the accuracy of the value assigned; to do it, without changing the resistance value on the
resistor box, switch the device to the temperature measurement mode, and verify that its reading is equal to
0±1 ºС.
•De-energize the device, disconnect the communication line from the resistor box and connect it to
RTD.
•After all these actions, the device is ready for further operation.

APPENDIX A
1 RS-485 COMMUNICATION INTERFACE
1.1 General information
The communication interface is employed to connect the TR-101 device to RS-485 network. The device
utilization within RS-485 network allows for the following functions.
•collecting data of measured temperatures within SCADA system;
•setting device parameters with use of configuration software;
•remote control of the channels output relays.
RS-485 as an interface standard has found extensive industrial application; it provides for establishing
networks with node count of up to 247 and data transfer at distance of up to 1200 m. With use of
duplicators, the number of nodes and the transmission distance can be increased.
All network devices are connected in a serial bus (Figure A1). To maintain the reliable operation of
transmitters/receivers and to eliminate interference impact, the communication line ends must be equipped
with a terminating resistor of impedance Rсогл = 120 Ohm that is connected immediately to the device
terminals (see Figure A1).
The device is connected to a PC via RS-485 /
RS-232 or RS-485 / USB interface adapter.
The data exchange may take place at one of
the following bitrates: 2400, 4800, 9600 bps.
1.2 Remote control for power relays.
By installation the value = 2 (table 7.1) device will be switched to the value of remote management
power relay. Control registers are shown at table A2.
If the channel working with two level action and labeled to control register value 0 or 1 is possible switch
on or switch off prorated power relay.
If the channel working with PID regulation and labeled to control register value 0 or 100 is possible to
manage capacity plug into correspondent relay (pos. 3.2.6.6 ).
If the mode ‘Remote management of power relay’ is switched on Tr-101 continuous working in usual
mode.
Exception is the fact that management of power relay is passed to operator.
1.3 Data exchange adjustment through interface RS-485.
Data exchange adjustment is realized by parameters:
– set switching on (switching off) RS-485 and the mode of remote management
– device base address (1…247);
-Rate of exchange the facts online (2400, 4800, 9600 bit/s);
– Time delay the packet answer 0-99,9 ms.
Device TR-101 has following fixed exchange parameters not shown at the indicator:
Quality Stop-bit –2; Length of a data word – 8; Parity check – not.
Attention! New option exchange value come into effect only after device restarting or restarting at
RS-485.
1.4 Data exchange through interface RS-485.
1.4.1 Working through interface RS-485 it should be done relevant connection (p. 1.1 of Appendix A)
and set the value of net parameters (p. 1.3 of Appendix A) .
1.4.2 For organization data exchange online through interface RS-485 necessary have net Master. The
main function of this device is to activate data exchange between sender and recipient. TP-101 may work
at Slave mode by ModBus RTU protocol.
