TEC Controller DX5100 Technical Manual 1. INTRODUCTION 1.1. Objective Thermoelectric Controller DX5100 (further the Controller) represents a precision-programmed device of management of thermoelectric coolers (TECs, the Peltier modules). In the device a bi-directional (heating and cooling) PID regulation is realized. Besides the PID regulation some additional modes of operation are realized in the Controller: the DC voltage mode, T-regulation and programming of an object temperature behavior with time. The device allows maintaining a given temperature of a thermoelectric (TE) cooler with high accuracy or programming heating and cooling in time. The function of diagnostics of an object of regulation - a TE cooler (TEC) is realized in the device. The diagnostics includes the measurement of the TEC resistance at alternating current, of TE figure-of-merit and of time constant. The function of the auto-tuning of the PID parameters is also implemented. The device is based on a modular principle. By this principle the Controller is divided functionally and physically into the control board and the Power Board in two variants: single-channel and two-channel, as well as peripheral and additional modules - the indication board and the interface board. The modular concept allows assembling the offered modules of the Controller configuration from oneand two-channel into a network design of many channels (32) of regulation joint by the control protocol RS485. Every channel has an independent algorithm of work. 1.2. Features - Bi-directional temperature regulation (heating and cooling) of a TEC with high accuracy - Work with RTD sensor and thermistors of both NTC and PTC types - One or two TECs controlled by one Controlling Board - Power channels of two versions: high-power 4Ax8V and low-power 3Ax5V - TEC operation current and voltage range as ±4A and ±8V per channel. - PID temperature regulation mode - Constant voltage operation mode - T-Regulation (relay) mode - Mode of temperature programming in time - Diagnostics of TEC performance by the Z-metering approach - PID auto-tuning function - Independent work without computer, based on preset and programmed start. - Communication interfaces RS232 and RS485 - Network of up to 32 Channels is available jointed by RS485 bus - Software for RS232 and RS485 protocols - Protocol WAKE for user software programming (library provided).

Connections of thermistor Due to the limitations of the 2-wire method, the 4-wire connection method shown in figure is recommended for sensors <1kOhm. Rw F+ T I Vm UT UIN Rw F- 2-Wire Connections F+ Rw S+ Rw T I Vm UT UIN S- Rw F- Rw 4-Wire Connections With this configuration, the test current (I) is forced through the thermistor through the F+ and F- wires, while the voltage across the thermistor is measured through a second set of wires connected to the S+ and S- (sense) terminals. Although some small current may flow through the sense wires, it is usually negligible and can generally be ignored for all practical purposes. Since the voltage drop across the sense wires is negligible, the voltage measured by controller is essentially the same as the voltage across the thermistor (VM = VT), and more accurate resistance and temperature measurements result from the following resistance calculation: Page 12 / 56 Version 3.37 / 2015 RMT Ltd. TEC Controller DX5100 Technical Manual RT UT I The wires to thermistor should be twisted for reduction of pickups (separate for pair force – contacts 1, 4 and sense wires – contacts 2, 3).

Power Board DX5102 The Power Board operates under the control of the Digital Control Board and provides: -Voltage output to the object of regulation -Voltage polarity control -Protection of converter microcircuit from overheating and from limiting current excess For external commutations there are connectors located on two sides of the board. The board is attached to the heatsink, which has threaded holes for mounting the module to an external heatsink (heat removal surface). Attention! It is not allowed to remove heatsink. Always put thermoconductive pad (enclosed) between heatsinks when placing on external heatsink. Remove protection layer from the pad before installation. External heatsinking is required for proper operation. Lack of proper heat dissipation may result in considerably reduced operation temperature range and device failure.

Digital Input-Output Board DX5107 By the board DX5107 the controller can carry out: - Control of a digital output depending on temperature of a channel (for each channel). On the circuit board there is a relay which responds a certain period after of the set temperature is achieved. - LED indication of the status of the digital output - Transition to the programs of control of channels by the signals entering the digital input. I.e. manipulating from the outside, for example by buttons, it is possible to transfer the controller to various modes of regulation. - Synchronization of work of the controller with work of external devices and with external events For external commutations there are connectors located on two sides of the board. For fastening the board there are 4 holes (=2.7mm, on the corners of the board).

Connections of Digital Input Buttons, switches, contacts of the relay or transistors can be used as a source of input signals (Open Drain or Open Collector Output). The board of the digital input is controlled by the bus I2C. The number of the port of extension on the bus I2C (for the command 0x44) - 04. The operation of the board is determined by the commands 0x4d and 0x4e (see Appendix 2). The command 0x4d serves to enable/disable the control of the relay depending on temperature of an object (according to parameters of the command 0x49). However even if the command 0x4d forbids the relay control, it is still possible to operate them by the command 0x44 (operations with bus I2C).

On pressing on and off the buttons there is a transition to the programs predetermined by command 0x4e (control of digital input). The front further is meant as a high potential on the input, the rising stands for a low one. Thus, for example, pressing on the button displayed in the figure causes a falling on the appropriate input. Pressing off - results in a rising. The first parameter of a command specifies the number of a channel, the second parameter is interpreted as follows: most significant nibble - № of the program to go to on a rising least significant nibble - № of the program to go to on a falling Since after the start by the button, one of the programs set by the command 4e is necessarily carried out, it is possible to stop this process by removing the extension of an appropriate digital input. For the interdiction not a level of the signal but a change of the enabling signal (front) is important.

Network Configuration Some modular solutions in different combinations (OEM1 – OEM3) can be connected in a network on the basis of the protocol RS-485. The cable RS-485 provided with the Digital Control Board serves for the connection to the network. The first contact of the connector XP6 and the red wire of the cable correspond to the signal "A" of the interface RS-485. The physical environment of signaling in the interface RS-485 is a twisted pair. Since the length of the cable is small, it is necessary to solder its wires to the wires of the twisted pair observing polarity. The place of the soldering should be insulated. Cable RS-485 Device 1 Device N When using long communication lines and high rates of exchange there can be negative phenomena as a signal reflection or distortion, etc. For these phenomena reduction, terminating resistor should be connected on the ends (and only on the ends) of the communication line. A terminating resistor is just a resistor connected on the end(s) of a cable. In an ideal, the resistance of terminating resistor equals the wave resistance of the cable. Terminating 120 Ohm resistors are placed in the Interface Converter DX5106 and on the Digital Control Board DX5101. The connection of terminating resistors is made with the help jumpers. For the connection of a terminating resistor in DX5106 it is necessary to connect the jumper J2 (MJ 2.0 mm). See section 3.8 "Interface Converter DX5106". For the connection of the terminating resistor in DX5101 it is necessary to connect the jumper J1 (MJ 2.0 mm). See section 3.3 "Digital Control Board DX5101". The network general topology on the basis of interface RS-485 with use of the interface converter USBRS485 is given below. Page 40 / 56 Version 3.37 / 2015 RMT Ltd.

However it demands knowledge of system of commands, see «System of commands» (for an advanced User). The detailed application is given in «DX5100 Vision. User Guide». A User has an opportunity to develop one's own software. For the communication with the device it is necessary to provide a compatibility of the protocol and the system of commands. When developing your own software, you can use the supplied library DX5100.dll. Examples of use are given in the "API DX5100 for LabView" and "API DX5100 for C". 3.13. Operation Modes 3.13.1. Constant Temperature The given mode provides maintenance of constant temperature of an object (TEC). Maintenance of temperature is carried out by TEC voltage calculated according to PID regulation. In this mode the voltage value and polarity are controlled. The temperature is controlled within the allowed limits. The size of the voltage is controlled and does not exceed the limiting value. The PID coefficients are set by a User. The start of regulation in this mode can be switched on by command or automatically after the Controller getting supplied (auto-start). Start of the temperature PID regulation by command 35 0 3 278.5 Switching on the maintenance of temperature. start the regulation of TEC1 to maintain the set temperature 278.5 K according to the PID law Auto-start of temperature PID regulation 3B 0 3 278.5 Page 42 / 56 Auto-starting of temperature maintenance. after restarting start the regulation of TEC1 to maintain set temperature 278.5 K according to the PID law Version 3.37 / 2015 RMT Ltd. TEC Controller DX5100 Technical Manual 3.13.2. Constant Voltage In the mode the TEC constant voltage is maintained in the appropriate polarity. A User should set a value of constant voltage allowing for a sign. The sign «-» stands for the heating polarity. The regulation in this mode can be performed by the command or automatically after switching on (autostart). Start of the constant voltage by command Switching on the maintenance of voltage start TEC2 in heating mode at constant voltage 2.3 V 35 1 4 -2.3 Auto-start of constant voltage mode Auto-starting of voltage maintenance after restarting start TEC2 in cooling mode at constant voltage 1.5 V 3B 1 4 1.5 3.13.3. Mode «Program» The Controller has a function “Program” - changing of operation mode in time. This function is carried out by the programs stored in the non-volatile memory. - Programs number up to 16 (0-15) - Number of lines in program up to 50 (0-49) Each line in program contains the following: - Temperature (setpoint) (K) for modes 2 and 3 or Voltage (V) for mode 4 (see below) - Time after which one has to leave this line of program (number of seconds - max 65535) - Most significant nibble – mode of current line (interpretation of the field of the first parameter of the program line as temperature or voltage). Possible values: 0 2 3 4 5 6 7 Interdiction of regulation T-regulation Temperature maintenance (PID) Constant voltage Setting the voltage of T-regulatory Adjust the settings Exit from the program without shutting down the last mode - Least significant nibble - number of program to go (0-15) on the expiration of the period Time - Number of line to go Each program (memory space for programming) has the following status: - 255 - there is no program - 0 - there is a program and it is the program beginning - 1-244 - there is a program and it is not the program beginning Stop the regulatory process and to stop work on the program, you can specify in the address line of transition value 0xFF (255). If the text of the program line number where you want to go - 0xFF, respectively, will be switched off (regulation will be stopped) It is possible to proceed to any line of any program - programs can be cascaded and cycled (repeat periodically). Cascading provides the duration of the process 50 steps and more. The cascading means that after one program performed another program starts. It is possible to stop the regulation process. For this purpose the set number of the program to proceed with should exceed 15. Version 3.37 / 2015 Page 43 / 56 TEC Controller DX5100 Technical Manual RMT Ltd. For reading, editing and recoding programs of temperature maintenance in time the command «Management of programs of change with time» used. By means of the command 45h it is possible to write or read a line of the program, to establish or read the status of the program. 45 0 14 1 278.5 60 3e 2 Response: 00 14 1 278.5 60 3e 2 45 1 14 1 0 0 0 0 Response: 01 14 1 278.5 60 3e 2 Or a possible response: 03 14 FF 0.00 0 0 0 45 2 14 00 0 0 0 0 Response: 02 14 0 0.00 0 0 0 45 3 14 00 0 0 0 0 Response: 02 14 00 0.00 0 0 0 Or a possible response: 03 14 FF 0.00 0 0 0 Line formation Write in line 1 of program 14 the setpoint 278.5 (K), maintenance time for this setting 60 (s), when the time is over proceed to line 2 of program 14 There has been a record of data according to the command in line 1 of program 14 Line reading Read line 1 of program 14 The contents of line 1 of program 14 corresponds to the previous example The status of program 14 (the space is free), there is no program Program status setting Set the status of program 14 equal 00.

T-Regulation (relay) Immediately after the launch of the specified mode for feasibility study on the maximum voltage is applied (for this type of feasibility study), commanded 25 per polarity determines the sign of the mismatch of the current temperature and the temperature setpoint. This is done as quickly as possible to achieve the set point. After reaching the set point controller switches to maintain the desired temperature. Page 44 / 56 Version 3.37 / 2015 RMT Ltd. TEC Controller DX5100 Technical Manual In the relay mode of regulation the TEC is exposed to the stepwise voltage equal to the specified UTreg (set by the command 26). Depending on a mismatch (the difference between the setpoint and current temperature) and a sign of the voltage UTreg, either the voltage UTreg, or 0 volts is supplied. T[K] 296 294 292 290 288 286 284 282 Tneed=280K U[V] UTECmax=8V UTreg=2V 0 The examples of T-regulation in the heating and cooling modes are followed. Note that the sign of the voltage specified by the command 26h, must comply with the regime: "+" - for the cooling mode, "-" - for heating. The described procedure is implemented in the firmware version 3.34. In earlier versions the voltage UTreg was applied to the TEC in the polarity depending on the mismatch. That is, the polarity changed but the voltage remained constant. The new algorithm provides a smaller temperature fluctuations in the vicinity of the setpoint. In the T-regulation mode signal "temperature is within the setting" will appear immediately after reaching the set point (the parameters set by a team of 49 are ignored). Removing the same signal out to the set defined by the parameters set by command 49 (Criterion alarm out to the set.) Version 3.37 / 2015 Page 45 / 56 TEC Controller DX5100 Technical Manual RMT Ltd. Voltage UTreg =-6V, and temperature setpoint is 340K. Voltage is UTreg= 6V and temperature setpoint is 280K. Page 46 / 56 Version 3.37 / 2015 RMT Ltd. TEC Controller DX5100 Technical Manual 4. HOW TO GET STARTED 4.1. Connections - Assemble the available OEM module of the Controller with connecting TEC (TECs) and thermistor (thermistors) according to the connecting procedure described. Important! For a proper functioning of an object of regulation it is necessary to provide effective heat rejection from the TEC hot side. It is achieved by a heat sink (probably with induced cooling) with good thermal contact of the TEC hot side and the heat sink surface. Important! It is necessary to provide a good thermal contact of the thermistor with the regulation object (TEC). The place of the thermistor should be chosen as close as possible to the cooled surface of the TEC to provide the minimal transport delay. The transport delay is the time after the moment of the voltage change to the moment of reception of the feedback signal - the change of temperature caused by this voltage change. - Connect the device to the network RS-485 and (or) to a COM-port of a computer by the cable RS-232 provided with the Digital Control Board. Connect to the connector XP7 or XP10 of the Digital Board, respectively. - Connect the power supply. As the power supply the source providing voltage 12V±10% should be chosen. Important! Power source should be chosen based on the total power of the Power Boards of the Controller and additional power consumption if the Controller is idling (Specification). If the maximal power required for a given TEC (Imax and Umax) are lower than the maximal characteristics of the Power Boards of the Controller, the the power source can be chosen with a smaller total power. Important! For correct operation of the board should provide them with proper cooling, possibly forced (with fans). Hardware current limit allows briefly slightly exceed the maximum allowed under current specifications . However, you should absolutely avoid long-term operation of the board at a current exceeding the allowable specification . In the case of passive cooling when the board is located without cover, with the orientation of elements - up, at ambient temperature isn't more than 25C - electric power (per channel ) mustn't exceed half of the maximum capacity. Under the conditions that impair the natural convection - this power is reduced. - Start the program DX5100 Vision or TEControl Terminal if working with a computer. - At auto-start the Controller will carry out the given program automatically. 4.2. Presets. The device is produced with the following factory settings: - Network address RS-485 - The device is tuned to receive the commands (by the protocol WAKE) via the interface 01 RS-232 BIN - PID parameters (two channels are identical by default) - TEC maximal voltage (V) 4.5 - PID coefficient Kp 0.03 - PID coefficient Ki 0.5 - PID coefficient Kd 0 - Criterion of the signal of setting value established (s) 20 - Criterion of the signal of setting value gone, s, 5 - Current mode of regulation Version 3.37 / 2015 Off Page 47 / 56 TEC Controller DX5100 Technical Manual RMT Ltd. - Setting temperature, K 293 - Auto-start Off - Maximum temperature of the object, K 403 - Minimum allowable temperature of the object, K 203 - Delay for starting of temperature protection, s 10 - The channels are (Alpha (K-1) =3.85E-03) adjusted for work with Pt thermistors 1000 Ohm Pt1000 4.3. Diagnostics Function The Controller can carry out the function of diagnostics of a TEC by the Z-metering method (Patent RU 2285980 C2 «Method of Thermoelectric Module Quality Control») The following parameters of an object controlled are measured: - TEC electrical resistance (R); - TE Figure-of-Merit(Z); - TEC time constant (); The relative change of these parameters in time can characterize the TEC degradation or the regulated object dynamics. The function of TEC diagnostics is supported by the commands: 37h - start of diagnostics By this command the measurement of TEC parameters (R, Z, ) is started. 37 0 200 start diagnostics of TEC1 with measurement time 200 seconds Important! The time 200 s does not include the time of delay to calm down the temperature field in the system. 3Eh - transfer the result of diagnostics By this command the latest diagnostics of the thermoelectric cooler and the measured parameters are outputted (R, Z, ). 3E Response: 01 0.97 2.36e-03 0.82 output the results of the TEC latest diagnostics the last TEC diagnosed was TEC2: R=0.97 Ohm 38h Z=2.36e-03 1/K =0.82 s - store the results of diagnostics as reference By this command the results of the latest diagnostics are stored as reference for the given TEC. These parameters can be used further for the degradation control of the TEC by comparison of the reference record with the results of current diagnostics. 38 3Fh store the results of diagnostics as reference - output the parameters of the diagnostics By this command the TEC reference data (R, Z, ) are outputted. 3F 01 Response: 01 0.97 2.36e-03 0.82 output the TEC2 stored parameters of the diagnostics the TEC2 reference data: R=0.97 Ohm Z=2.36e-03 1/K =0.82 s 4.4. Auto-PID Function The PID temperature regulation efficiency is determined by a choice of optimum coefficients of regulation for a given object. Page 48 / 56 Version 3.37 / 2015 RMT Ltd. TEC Controller DX5100 Technical Manual The consecutive iterative selection of coefficients does not always provide a choice of optimum parameters and demands quite a long time and User's experience. For simplification of the task of the optimum PID parameters selection there is a function in the Controller program providing their preliminary estimation. The concept is based on the Ziegler-Nichols method. In detail the auto-PID algorithm is described in Appendix 3. By the command auto-PID the procedure of the object special diagnostics is started in conformity with the algorithm - see Appendix 3. By the results of this diagnostics approximate PID coefficients are calculated. The PID coefficients offered by the auto-PID procedure can be used by a User for serve as approximate values for the subsequent User's fine adjustments. For example, the criteria of the optimum adjustment, can be the settling time, minimal overshoot, or accuracy of temperature maintenance. The default (the delivery) factory PID parameters values are given above. The autotuning function searches the values of proportional, integral and differential coefficients of the PID algorithm. The coefficients are obtained for the cooling mode in which all the ADC channels are allowed to be measured – the longest sampling period of PID. During autotuning no commands are received and no information frames are outputted. The LED indication stops (the beginning of it can be a signal of the autotuning end). During the process autotuning, as the intermediate stages being over, the debugging information may be outputted into a non-command interface. After the process of autotuning is over, the coefficients of a corresponding PID channel are set. Function of auto-PID is supported by the commands: 51h - start auto-PID; 51 0 start auto-PID of TEC1 After this command reception the Controller sends the information frame with the message “Tuning PID № started. Wait!!!” 32h - send PID controller coefficients By this command the PID coefficients are outputted. 32 01 send PID algorithm coefficients for regulation TEC2 Response: 01 0.029000 0.278000 0.000000 PID algorithm coefficients for regulation TEC2 Kp=0.029 Ki=0.278 Kd=0 It is necessary to note that during the autotuning of any channel, the regulation on the other channel stops. 4.5. Working with RS232 and RS485 Both interfaces are serial and use the following adjustments: Rate Information bits parity stop bits flow control 19200 baud (default) 8 Not available 1 Not available One of the interfaces is used for management of the Controller (sending commands and reception of responding frames via the protocol WAKE). I.e. WAKE can function in any of the named interfaces. For definiteness we shall name the interface in which WAKE works as the command interface. Version 3.37 / 2015 Page 49 / 56 TEC Controller DX5100 Technical Manual RMT Ltd. The protocol WAKE suggests a half-duplex exchange. It does not give enable the device to output information on its own initiative via the command interface. For this purpose (outputting of the telemetry on the initiative of the device) the other interface (where WAKE does not work) is used. Thus, each of the interfaces realized in the Controller can be command. The assignment of the status command to the interface is by sending the command 4Bh. (see Appendix 2) It means that after switching on, the interface established by the command 4Bh will be command. If connecting to the interface that at present is not the command one, it is impossible to operate the device at once. To give the connected interface the status command for the current session it is necessary to send the sequence of symbols «$&%» to an appropriate COM-port. The reception of this sequence via any interface switches the device into the mode of commands reception via this interface. The specified sequence of symbols can be given in any terminal program. Also it is possible to output it by the command 02h - «Transfer an echo». 02 @$&% switch the reception of commands to the interface on which this command is accepted. The response to this command is not sent. The protocol WAKE will further work via the interface by which the command has arrived. However, after turning off and repeated switching on of the device, the command interface will be again the one established by the command 4Bh. 4.6. Light Indication There are four LEDs on the Digital Control Board (LED 1…LED 4). Just after switching ON the Device, during 1 sec LEDs show the exchange rate per interface and the mode WAKE corresponding to the Table below.

It arises, if when reading the calibrating and adjusting parameters stored in the non-volatile memory, there was an error in checking the control sum. This error is critical. The supply voltage of the device has gone out of the allowable limits 12V±10%. Occurrence of the error is accompanied by switching off of the voltage converters. The error remains true even after voltage returning to allowable limits. This error is critical. The bite dump can be made only by resetting (switching off and repeated switching on) of the device.

Since the Firmware version 441, the Indication Board can be used not only for imaging parameters but also for management the controller. You can launch the channel regulation of the previously prepared program and also stop regulation on the channels. Important! The program should be prepared and stored in the controller. Special screen (E6) is used for manage the controller, E6 screen can be accessible from the E2 or E3 screens. If regulation is disabled – E6 screen displayed start string with program number (START Pr-XX). The program number can be changed with buttons. Hold of the right button starts the program (XX). If the channel mode isn't OFF or it is working on the program, the E6 is a string stop (STOP). Hold of the right key will stop regulation. Which channel will start or stop depends on the screen, which preceded E6. If in E6 no button is pressed within 5 seconds - will return to screens E2 or E3.

Storage and Recovery of Parameters The working parameters of the Controller stored in the non-volatile memory of the Digital Control Board, can be outputted for backup (storage) and, if necessary, recovered. The parameters are outputted by the command 41h, received and stored - by the command 42h. It is expedient to take advantage of an opportunity of the parameters storage before the procedures changing them, and also after their end. Such procedures, for example, are calibration, storage of the thermistor polynomial, etc. Backup Procedure 1. Connect the device to a computer by command interface (RS232 or RS485).
