Introduction
Thank you for choosing the 5400 Series TECSource from Arroyo Instruments.
Your TECSource is a combination of leading edge technology combined with
years of experience in the field of temperature control.
With a crystal clear 4-line VFD display, very high power output, multi-sensor
support, both RS232 and USB computer interfaces, and auxiliary I/O, the
TECSource will fit into almost any temperature control application.
Unlike other temperature controllers in its class which use inexpensive 7-
segment LED displays, the TECSource takes advantage of its large VFD display
to simultaneously display set point temperature, actual temperature, current, and
voltage.
The user interface of the TECSource is engineered to make using the
instrument straightforward. With its text-based menus, there is never any
confusion over which setting is being changed, and parameters are displayed in
clear English (no cryptic numbers or LEDs to decode).
The TECSource offers all the features you would expect from a modern
temperature controller, including:
AutoTune for automatic PID parameter calculation
0.004°C temperature stability
0.001°C resolution for both set point and actual temperatures
What’s in the Box
Along with the TECSource itself, you will find a printed copy of the manual, a 2-
pin interlock header, and a CD with electronic copies of this manual, the

Quick Start
The 5400 TECSource was designed with ease of use in mind, and you will likely
have little need for this manual for almost all of the features the unit offers. This
section will show how you can quickly get the unit up and running in almost no
time.
The TECSource has a universal input power supply, accepting 90 to 240 VAC,
and 50 or 60 Hz. This covers all conventional power worldwide, but ensure your
AC power meets these requirements.
Plug the AC cord into the unit and into the wall outlet. Turn on the power switch
located on the IPC, and the unit will power up, displaying the model information
and firmware version number.
Press the Menu button to enter the menu, and using the knob, turn to the right
until the I Lim setting is displayed. Press the knob to edit the setting, and adjust
the limit as appropriate to your Peltier. Press the knob again to save the value.
Make the same adjustments to the high and low temperature limits (T-High Lim
and T-Low Lim), as appropriate for your application.
The unit comes pre-programmed for the BetaTHERM 10K3A1 thermistor. If the
TECSource is being connected to a LaserMount, no changes need to be
made, as this is the thermistor used in the mount. However, if you are using
manufacturer’s thermistor or a different BetaTHERM thermistor, you will need to
verify the Steinhart-Hart coefficients are set correctly. Navigate to the Main
Sensor Menu, pressing the knob to enter the sub-menu. Adjust the constants to
reflect the values for your thermistor.
Once you have made all your adjustments, press the Menu button to exit the
menu (in the future, if you’re only changing one value, you do not need to press
the knob --- pressing the Menu button while changing a value will save the value
and exit).
Next, connect the cable between your LaserMount or other fixture and the
Output connector of the TECSource. We recommend using our cables as they
have been designed to work well with the TECSource. If using your own cables,
ensure they have been properly wired according to the pin-out of the
TECSource and your fixture.
Finally, set the set point to an appropriate temperature and press the Output
button. The output will turn on and you will see the voltage and current begin
driving the fixture to the set point you have chosen. Depending on the thermal
size of your fixture, it may take seconds or several minutes to reach the set
point.

5400 Series TECSource User’s Manual · Page 7
If you notice the temperature is oscillating around the set point and not
stabilizing, you may need to adjust the Gain setting in the menu. You can use
the AutoTune PID feature to automatically calculate the best PID values, or
select from a set of eight factory preset values that typically cover most
applications. To use the factory gains, if the temperature is quickly jumping up
and down, the Gain will typically need to be reduced. If the temperature is slowly
moving up and down, try a higher Gain. You may need to experiment with
several gain settings to find the ideal value, and for even finer control, you can
set the Gain to PID and directly set the PID control values.
For more detailed operating and installation instructions, read on.
Installation
Installation of the 5400 TECSource is very straightforward, as the quick start
section above illustrated. This section will provide additional details and
considerations for installing your TECSource.
After unpacking the unit, make sure all packing materials have been removed
and nothing obscures the ventilation ports on the back and bottom of the unit.
The TECSource has a universal input power supply, accepting 90 to 240 VAC,
and 50 or 60 Hz. This covers all conventional power worldwide, but ensure your
AC power meets these requirements.
Powering Up the Unit
Once the correct voltage selection has been made, connect the AC power cord
to the unit.
Turn the power switch, located on the front of the unit, into the on (|) position.
The unit will display the current firmware revision, go through a quick power-up
self-test, and return to the last known operating state.
CAUTION
Do not exceed 250VAC on the line input.
It is critical to select the proper voltage selection prior to
applying power to the unit. If the actual voltage exceeds
the voltage selection by +/-10%, damage to the unit
may occur.

Page 8 · 5400 Series TECSource User’s Manual
Ventilation
The TECSource has vent holes on the rear and left side of the unit. You must
not block these vent holes, or overheating may occur, causing damage to the
unit.
Rack Mounting
The rack mounting kit (p/n 1403-RM) for standard 19” racks are available for the
TECSource. Because the unit draws air from the side, and therefore inside the
rack housing, be sure that the internal rack ambient temperature (which will
typically be several degrees higher than room ambient) does not exceed the
unit’s operating temperature.
Warm-up and Environmental Considerations
In order to achieve the highest level of accuracy, the TECSource should be
powered on for at least one hour prior to taking measurements. In addition,
ensure that the unit is not operating outside the ambient temperature range or
humidity conditions.
NOTE
As the unit nears maximum load conditions, it is normal
for the internal fan to significantly increase in speed.
CAUTION
Do not operate the unit above +40°C ambient, and
ensure the instrument is properly ventilated, or the unit
may overheat and possible damage to the instrument
may occur.

Power and Cable Connections
In addition to the input power connector described above, there are five
connectors on the rear panel of the TECSource: Output connector, Auxiliary
connector, Interlock connector, USB connector, and RS232 connector.
TECSource Rear Panel
TEC Output Connector
The Output connector is a female 17W2, and has the following pin-out:

6 Sensor 2– 13 Earth Ground
7 Fan+ 14 Sensor 2+
15 Fan– (Signal Ground)
Output Connector (17W2 Female)
Inverting the TE Output
In the event the polarity of the TE pins is backwards, it is possible to reverse the
direction of the TEC current by setting the Advanced » Invert ITE to Yes. While
not recommended as it can lead to confusion when the controller is used later is
properly wired setups, this allows for correct operation of system when the TE
pins are wired backwards and rewiring is not possible or feasible.
Using Remote Sensor
The Remote Sensor 1 pins (10 & 11) are used in RTD 4-wire mode, and provide
a remote measurement of the RTD voltage to eliminate voltage measurement

Page 10 · 5400 Series TECSource User’s Manual
errors. See Working with RTDs below for more information. Only Sensor 1 has 4-
wire remote sense capability.
Using Remote TEC Voltage Sense
The Remote TEC Voltage Sense pins (2 & 9) are used to remotely measure the
TEC voltage. See Using Remote TEC Voltage Sense below for more information.
Using the TEC On LED
Pins 1 & 8 on the Output connector can be used to drive an LED to indicate
when the TEC is on. The signal is driven from a +5V buffer with a 249Ωresistor
in series with the output, limiting the current to 20mA. This is suitable for the
direct connection of most green and red LEDs. Add additional series resistance
for lower current devices, such as blue LEDs.

Connecting to the TECSource
Arroyo Instruments carries two cable assemblies specifically designed for
connecting the TECSource to temperature controlled fixtures or devices. The
1264 is a two meter cable, capable of up to 30A of TEC current, designed for
use with Arroyo Instruments mounts, and has 17W2 connectors on both ends,
one male and one female. The 1265 is identical to the 1264, except that it has
bare wires on the device end, allowing you to terminate the cable with your own
connector or mount.
See the manual for your fixture for additional safety and operational information.
Front Panel Operation
Operation of the TECSource is very straightforward. The sections below will
help familiarize you with the front panel, the display, and the menu structure.
The front panel is designed for simplicity in operation. There are six buttons on
the front panel: Output, Menu, Display, Func A, Func B, and the adjustment
knob button.
The Output button is used to turn the output on and off. Whenever the output is
on, the blue Output On LED will be lit.
The Menu button is used to enter the TECSource menu. When in remote mode,
it acts as a Local button, returning the instrument to local mode.
NOTE
Connections to the TECSource and the fixture must be
secure. Tighten any screws on the connectors, and
make sure all connections are in good condition.

5400 Series TECSource User’s Manual · Page 13
The Display button is used to cycle through the display modes of the controller.
Because the controller monitors more information than can be displayed at
once, the Display button allows you to cycle between the TEC information,
auxiliary temperature measurements, and digital I/O status.
The Func A and Func B buttons are used to execute user-defined macros,
recall saved settings, or other actions as defined in the Function Keys Menu.
The large adjustment knob located on the right hand side of the unit is used to
change the set point or parameters in the menu. It also acts as a push button,
primarily as an enter button, when making changes in the menu.
There are ten LEDs:
Color Function When lit, indicates:
Blue Output On TECSource is actively controlling the temperature
Red Error Error has occurred
Yellow Remote Unit is being controlled via a computer
Green Cool Instrument is cooling
Green Heat Instrument is heating
Green Stable Temperature is stable
Green ITE Limit Controller is in current limit
Green VTE Limit Controller is in voltage limit
Yellow T Limit Controller is in temperature limit
Green Link Controller is linked to another instrument
Whenever an error is generated, the red Error LED will light, and the error will be
displayed on the VFD display. There may be one or more errors, but only the
first error will be displayed. To display the next error, press Menu button. To
clear all errors, press the knob. A list of error codes can be found in the Error
Messages section below.
When the unit is in remote mode, the yellow Remote LED will be lit. More
information about how the instrument behaves in remote mode can be found in
the Remote Mode Operation section below.
Control Modes
The TECSource offers three control modes: constant temperature mode (T
Mode), and constant resistance mode (R Mode), and constant current mode (Ite
Mode).

Page 14 · 5400 Series TECSource User’s Manual
Changing the control mode is done through the menu by changing the Mode
parameter to T Mode, R Mode, or Ite Mode.
Constant temperature mode uses the sensor constants to calculate the
resistance of the thermistor at the desired or actual temperature.
While most users will only need the temperature control mode, the constant
resistance mode allows you to bypass the sensor equation and directly select
the sensor set point. This can be useful when only the desired sensor value is
known, or when the sensor-to-temperature conversion values are not available
for your sensor.
Main Display Screen
The top of the main display will be the temperature of the active sensor, except
when adjusting the set point. The bottom half of the display can display one of
three sets of data:
1. Set point and TEC current and voltage
2. Sensor readings for the non-active primary sensors
3. Sensor readings for the auxiliary sensors
4. Digital input and output status
Example displays are shown below:
Main Display: Set Point and TEC Current and Voltage
Main Display: Additional Primary Sensors
T=25.000°c
Sens 2= 25.000°c
Sens 3= Disabled
T=25.000°c
TSET= 25.000°c
I= 3.25AV= 6.72V

5400 Series TECSource User’s Manual · Page 15
Main Display: Auxiliary Sensors
Main Display: Digital I/O State
The set point will depend on the control mode you have selected. When in T
Mode, the set point will be temperature. When in R Mode, the set point will be in
the active sensor’s units (ohms for thermistor and RTD, uA for AD590, and mV
for LM335). When in Ite Mode, the set point will be in amps.
Measurements
The second line of the display contains the measurements appropriate for the
control mode. In T Mode, the actual temperature, current, and voltage can be
displayed, depending on the display mode. In R Mode, the actual sensor value
is displayed instead of the actual temperature. In Ite Mode, the actual
temperature is displayed.
No Set Point Error
Because the TECSource uses a digital PID loop, it will always stabilize at the set
point, and you will never have a temperature offset often found with analog
controllers.
Using Limits
The TECSource supports four different types of limits: temperature, sensor,
current, and voltage. There is both a temperature high and temperature low limit,
and if the actual temperature exceeds either of these limits, the output will be
shut off. Likewise, both high and low limits exist for the sensor (R limits), and the
output will be shut off if the sensor measurement exceeds either of these limits,
as determined by settings in the Output Off Menu.
T=25.000°c
Din 1/2/I:On / Off / Off
Dout 1/2/R:Off / Off / Off
T=25.000°c
Ax1=25.00 Ax3= Dis
Ax2=25.00 Ax4= Dis

Page 16 · 5400 Series TECSource User’s Manual
Settings and Menus
All parameters of the TECSource can be viewed and changed within the menu
(except for the user calibration adjustments, which must be done via the
computer interface). The menus are constructed with the most used parameters
first. To change any setting, press Menu to enter the menu then rotate the knob
to select the parameter to change. Press the knob to begin changing the value.
As a visual indication that you are in edit mode, you will see an asterisk appear
next to the value. Once you have made your change, press the knob or Menu
button to store the value. Pressing the Menu button will store and exit the menu,
while pressing the knob will store the value but leave you in the menu to make
additional changes.
Some settings are contained inside a sub menu, such as communications
settings. To access the sub menu, simply press the knob to enter the sub menu
when its name is displayed.
