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.

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:

In Digital Control Board DX5101 there is an opportunity to choose one of two possible values test
current (Iforce1 or Iforce2).
3.4. 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.

3.9.4. 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.

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.

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.

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.)

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.

4.3. 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

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:

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.

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

Controlling with Indication board.
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.

4.8. 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). If it is possible connect
the device to a computer by not command interface.
2.
Start the program TEControl Terminal and adjust it for work with the interface that is command
3.
Send the command
41
Send the parameters stored in FLASH.
After sending this command the device gives out the contents of
structure with parameters kept in the non-volatile memory into the
interface from which will receive any symbol. Each byte is transferred
as two hexadecimal figures.
4.
If is used only one interface - disconnect communication.
5.
Start the program Hyper Terminal (included in the MS Windows) or other terminal program by means
of which it is possible to write the file of exchange protocol. Adjust the terminal program for work with
the interface that is not command in the device. If is used only one interface adjust for work with the
command interface.
6.
Switch on protocol storage in a file in the Hyper terminal program (Menu - Transfer - Save as). Specify
the file place and name for storage.
7.
Press any key. Data will transferred.
8.
Stop protocol storage in a file in the terminal program (Menu - Transfer - Storage in a file - Stop).
The file specified in item #4 can be used for recovery.
Procedure of Recovery from Backup
1.
Connect the device to a computer by by command interface (RS232 or RS485). If it is possible
connect the device to a computer by not command interface.
2.
Start the program TEControl Terminal and adjust it for work with the interface that is command.
3.
Send the command
41
Store the parameters stored in FLASH.
After sending this command the device expects data and interprets them
as given by the command 41. The data received are stored in the
structure and then are stored in the non-volatile memory.
4.
If is used only one interface - disconnect communication.
5.
Start the program Hyper Terminal (included in the delivery of MS Windows) or other terminal program
by means of which it is possible to send the text file. Adjust the terminal program for work with the
interface that is not command in the device. If is used only one interface adjust for work with the
command interface.
6.
Send the backup file protocol storage in a file in the terminal program (Menu - Transfer – Send the text
file). Specify the file place and name.
