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, 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 Characteristic Shift

To provide for the error compensation ΔR = (R0 - R0.TC) produced by the input wiring resistance RTC, each measured temperature value (Tmeas) is added with a user specified value δ. Figure 3.3 shows an example of a characteristics shift for Pt100 sensor.

Programmable parameters: Sh1, Sh2, Sh3, Sh4

Figure 3.3 – Characteristic shift example for Pt100 sensor

3.2.3.2 Characteristic Slope

To provide for sensor error compensation upon W100 value deviation from the rated value, each Tmeas 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: KU1, KU2, KU3, KU4

Figure 3.4 – Characteristic slope example for Pt100 sensor

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: Fb1, Fb2, Fb3, Fb4
• Digital filter time constant: Ft1, Ft2, Ft3, Ft4

The filters are set for each input independently.

3.2.4.1 Digital Filter Band

The digital filter band allows protecting the measurement route from single interference and is set in °C. If the measured value Tmeas is different from the previous Tmeas–1 by the value larger than the Fb parameter value, the device assigns to it a value equal to (Tmeas + Fb). Thus the characteristic is smoothed out.

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 Fb1 (Fb2, Fb3, Fb4) 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 Digital Filter Time Constant

The digital filter eliminates the noise signal components by smoothing it exponentially. The main characteristic of the exponential filter is τf – the digital filter time constant, Ft1 (Ft2, Ft3, Ft4) interval, within which the temperature reaches the 63.2% from measured value Tmeas.

Reducing τf will lead to a faster device reaction onto discontinuous temperature variations, but also will reduce its protection against interference. Increasing τf value increases the device response rate, while noise is significantly suppressed.

Figure 3.5 – Filter band characteristic Figure 3.6 – Filter time constant characteristic

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:

Logic №1 (Heater) – used to control a heater operation (tubular electric heaters, for instance), or to produce warning that the current temperature value (Tcurr) is less than the setting value (Tset).

• The output relay initially closes at values of Tcurr < Tset – HS
• Then opens at Tcurr > Tset + HS
• And closes again at Tcurr < Tset – HS

This effects the two-position control by Tset setting with the HS hysteresis.

Logic №2 (Cooler) – used to control a cooler operation (a fan, for instance), or a warning of exceeding Tset setting value.

• The output relay initially is ON at values of Tcurr > Tset + HS
• Then is OFF at Tcurr < Tset
• And ON again at Tcurr > Tset + HS

Caution

If using as compressor cooler, it is recommended to define HS in such a manner to provide the normal (minimum) compressor off time to avoid the device damage.

Figure 3.7 – Diagram of output relay function based on the logic type

Programmable parameters:

• Tset – temperature setting: SP1 (SP2, SP3, SP4)
• HS – hysteresis: HS1 (HS2, HS3, HS4)
• Relay function logic: rt1 (rt2, rt3, rt4)

3.2.6 PID-Controller (Proportional-Plus-Integral-Plus-Derivative Control)

3.2.6.1 PID Control General Principles

On the control relay the “controlling” signal Yi is generated; its action is directed at reducing the Ei deviation.

Where:

• Xp – proportionality band (programmable parameter P)
• Ei – is the difference between the set Tset and current Tcurr temperature value, or unbalance
• τd – response speed derivation (programmable parameter “PID-controller derivative constant” - d)
• ΔEi – difference between two adjacent measurements Ei and Ei-1
• Δtmeas – difference between two adjacent measurements Tcurr and Tcurr-1
• τi – integration response time (programmable parameter “PID controller integral constant” i)
• Σ – derivation cumulative sum

To provide for the efficient PID controller operation it is important that proper values of Xp, τd and τi ratios for the given controlled object be set.

Programmable parameters:

• [Xp] – P1 (P2, P3, P4)
• [τd] – d1 (d2, d3, d4)
• [τi] – i1 (i2, i3, i4)

Note

Sometimes PID regulation is overmuch or inadmissible. In such cases fixing coefficient τi = 0 or τd = 0 is possible to get PD and PI regulator.

3.2.6.2 Proportional Regulator

Proportional regulator is the main where the task of temperature is directly proportional to error. Using only proportional regulator leads to error. The low values of proportional regulator lead to lack of stability and vibration in system but too high lead to low operation.

Figure 3.8 – Working diagram of proportional regulator

3.2.6.3 Integral Regulator

It’s used for compensation of errors. The temperature will grow to the moment compensation of errors (or diminish by negative error). The minor constituents of integral element influence the regulator job much.

If the value fixed very high it means the system doesn’t recognize it and will work with overshoot.

Figure 3.9 – Working diagram of integral regulator

3.2.6.4 Differential Regulator

It’s used for increasing system performance rating the error change.

The regulator speeding leads to increasing 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 diagram 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: rt1 (rt2, rt3, rt4)

Caution

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 according to the following formula:

D = Tcycle × Yi / 100

Where:

• D – impulse duration (seconds): L1, L2, L3, L4
• Tcycle – pulse repetition period (seconds): t1, t2, t3, t4
• Yi – command current of PID regulator (%)

Figure 3.11 – Diagram of output relay action in PID regulation mode

Caution

The small value of Tcycle leads to often commutation and short life power contacts but the big value of Tcycle leads to quality loss regulation.

3.2.7 RS-485 Communication Interface

Using of interface is described in Appendix A.

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.

Note

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 to install 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.

Danger

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 than 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, when TR-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 for the wires parasitic resistance, perform the following:

1. 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)).

2. Then connect a resistor box with accuracy rating not less than 0.05 (P321, for example) to the opposite ends of the “device-sensor” communication line, instead of the thermal element.

3. On the resistor box, set the value equal to the RTD resistance at temperature of 0 °C (50, 100, 500, 1000 Ohms, depending on the sensor type).

4. Energize the device and after 20-30 sec, by the digital display readings, define the value of the temperature deviation from 0 °C.

5. Set the Sh1 (Sh2, Sh3, Sh4) parameter value equal to the temperature deviation value, taken with the opposite sign.

6. 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 °C.

7. De-energize the device, disconnect the communication line from the resistor box and connect it to RTD.

8. After all these actions, the device is ready for further operation.

Caution

To avoid interference impact to the measurement part of the device, the “device-sensor” communication lines must be:

• made of screened cable of twisted pair (triple);
• have section of not less than 0.5 mm²;
• be reliably connected to the device terminals;
• the cable connection route must be separate from the high voltage cables and inductive load feeding cables.

Danger

THE DEVICE IS NOT INTENDED FOR THE LOAD COMMUTATION IN CASE OF SHORT CIRCUIT. THEREFORE THE DEVICE SHOULD BE OPERATED IN THE ELECTRICAL MAINS PROTECTED BY THE CIRCUIT BREAKER WITH INTERRUPTING CURRENT OF 16 A MAXIMUM OF CLASS B.

6.2 Output Relay Testing

The device gives an opportunity to test both all relays at once, or each relay independently; to test, perform the following:

1. When in parameter edit mode, set the tSt parameter value according to Table 7.1 and press ENTER key; upon that, the display will show OFF message (which means that all relays that are being tested are currently in the normally open (de-energized) state), all LED lights will go off.

2. Single pressing of ENTER key changes the status of the relays under testing:

   • OFF – the relays are in normally open (de-energized) state
   • On – the relays are in normally closed (energized) state

3. To switch back to the menu press the MENU key. If no key is pressed during 20 sec the TR-101 device goes into the initial state.

7.2 Programming Sequence

7.2.1 Setting Up Measurement Entry Parameters

7.2.1.1 Enter the Ct1 (Ct2, Ct3, Ct4) parameter value in accordance with the sensor type (Table 1, Table 7.1).

7.2.1.2 Measurement Characteristic Adjustment

The measurement adjustment procedure performed by the device is described in paragraph 3.2.3. The device performs measurement adjustment after the necessary values for parameters Sh – sensor measurement characteristic shift and KU – sensor measurement characteristic slope, have been set.

• Sh parameter can be modified within boundaries from -50 to +50 °C
• KU parameter can be modified within boundaries from 0.50 to 2.00

Note

1. The necessity of measurement accuracy adjustment becomes clear after the sensors and device have been verified.
2. When thermal element is connected under a two-wire diagram, the Sh parameter must be entered. The Sh parameter value definition is performed according to methodology described in 5.3.1.

7.2.2 Setting Up Digital Filter Parameters

The digital filter operation is described in paragraph 3.2.4.

The measurement digital filter setting up is performed by specifying two parameters values:

• Fb – digital filter band
• Ft – digital filter time constant

The Ft value can be set within limits from 0 to 60 sec; when Ft = 0 filtration by way of exponential smoothing is unavailable.

The Fb value is set within range from 0 to 200 °C; when Fb = 0 the “single interference termination” is off.

7.2.3 Setting Up Relay Control Method Parameters

For a specific regulation system, the control method has to be selected by means of setting corresponding values to rt1 (rt2, rt3, rt4) parameter:

• 0 – logic 1 (heater)
• 1 – logic 2 (cooler)

7.2.4 Setting Control Modes

The device can function in one of the two modes: the two-position control and PID-control.

The proper mode is set by specifying a proper value for ch1 (ch2, ch3, ch4) parameter:

• 0 – OFF
• 1 – two-position control
• 2 – PID control
• 3 – Automatic adjustment of PID regulator

The two-position control and PID control operation is described in paragraphs 3.2.5 and 3.2.6.

The two-position controller hysteresis HS (°C) is set under HS1 (HS2, HS3, HS4) parameter, see 3.2.5; the parameter may be modified within range from 0 to +50 °C.

7.2.5 PID Regulator Adjustment

7.2.5.1 General Concept

PID regulator operation is described at p. 3.2.6.

For adjustment of PID regulator needed attend following actions:

1. Set value of regulator setting SP1 (SP2, SP3, SP4)
2. Set parameters of pulse-length modulation (PLM) regulation:
   • t – pulse repetition period Tcycle
   • L – minimal pulse length
3. Set parameters of PID regulation:
   • P – Proportionality band of regulator Xp
   • i – Reaction time of integration τi
   • d – Reaction time of differentiator τd

Option setting t1 (t2, t3, t4) set in seconds from 60 to 999.

Option setting L1 (L2, L3, L4) set in seconds from 1 to 999.

Option setting P1 (P2, P3, P4) set in °C from 1 to 999.

Option setting i1 (i2, i3, i4) set in minutes from 0 to 999. For i = 0 device works as PD regulator.

Option setting d1 (d2, d3, d4) set in minutes from 0 to 999. For d = 0 device works as PI regulator.

For i = 0 and d = 0 device works as P regulator.

Considering that at each individual scheme there are non-periodic External actions of different characters, all coefficients in above shown formulas can change for getting optimal behavior in positive conditions.

Selected parameters for superfine temperature maintenance in steady-state may happen totally unacceptable for suppression transient phenomena for External action or on-exit onto mode.

As well as alternatively.

For another thing in the course of operation controlled plant characteristic regulation can change very much. Like for operational changes and in time.

Usually calculated values require repeated correcting and selection. And changing single parameter involves necessity correcting other.

7.2.5.2 Automatic Adjustment of PID Regulator

This mode designed to autodetection initial approximate values of PID coefficients τi, τd and Xp when operated at concrete scheme.

Automatic tuning is recommended to lead by start and system debugging.

7.2.5.2.1 Enter to program mode (see p. 7.1.3).

7.2.5.2.2 Define SP (Tset) like setting value which in future will be supported by device.

If necessary fix PLM pulses repetition period and minimal PLM pulse length, parameters t1 and L1.

Factory settings are t1 = 60 seconds, L1 = 1 second.

7.2.5.2.3 Define parameter ch1 = 3 (ch2, ch3, ch4).

After pressing key ENTER, at display device will appear blinking caption Pid with number display device for 10 seconds (the time can change depending on fixed time filter Ft1, Ft2, Ft3, Ft4).

On the morrow of time regulator will give continuous output limit and at display device will appear current temperature dotted in low order position “xxx.”.

Whereby output relay of loading will be power on till will not be reach the volume of temperature like SP (Tset).

After switching off loading relay (period I, point B) sometime the temperature mechanically will increase further.

As soon as the control temperature will come down below SP (Tset), process automatic tuning will finish (point G at Figure 7.1) and display device will show continuous lettering Pid.

TR-101 calculates coefficient of PID regulator: band proportionality, characteristic time of integration, characteristic time of differentiator.

After finishing automatic tuning needed press key MENU and switch device to program mode in which is possible to look and correct received coefficients value.

The coefficients were received as a result of “Automatic tuning PID” are not optimal and work for preliminary analysis.

Note

For cancellation started mode of automatic tuning needed hold the MENU key for seven seconds.

7.2.5.3 PID Regulator Manual Setting

Below mentioned method allows defining approximate generic parameters of regulator.

7.2.5.3.1 Enter to program mode.

7.2.5.3.2 If necessary, fix PLM pulses repetition period and minimal PLM pulse length, parameters t and L.

Factory settings are t = 60 seconds, L = 1 second.

7.2.5.3.3 Fix the value equal to zero for i (τi), d (τd) and P (Xp). Fix SP (Tset) value equal to temperature setting value which will be supported by device in future.

After passage to mode regulation (at the end of 20 seconds the device automatically passes into mode regulation) output relay of loading will be power on till fail to reach regulation temperature (setting limit) Tset (period I, point B at Figure 7.1).

7.2.5.3.4 Take measure t₁ – time from the moment of temperature increase to 10% (point A at Figure 7.1) and to the moment of temperature increase to 63% from the range Tset − Tmax (point B at Figure 7.1).

7.2.5.3.6 Take measure of maximum value overshoot between points B and G (Emax, Figure 7.1).

7.2.5.3.7 Fix the value Xp = 2 × Emax (period II at Figure 7.1).

Make sure that for datum value Xp does not absent achievement of setting value Tset. Otherwise necessary increase the value Xp.

If the value of Xp = 2 × Emax and the difference between steady-state temperature and setting value is too much, then need to diminish Xp.

7.2.5.3.8 Fix the value τi = 2.4 × t₁. Make sure that given value τi not appear temperature vibration around setting value (period III). For decreasing vibration is necessary increase value τi, for increasing delivery speed necessary diminish value τi.

7.2.5.3.9 Fix the value τd equal to [0.1; 0.2; 0.3; 0.4] × τobj.
