Page 5: Quick Start
5235 TECSource User’s Manual · Page 5 Quick Start 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.
Page 6 Page 6 · 5235 TECSource User’s Manual 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. If the temperature is quickly jumping up and down, the Gain will typically need to be reduced.
Page 7: Installation
5235 TECSource User’s Manual · Page 7 Installation Installation of the 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.
Page 8 Page 8 · 5235 TECSource User’s Manual Rack Mounting A rack mount kit (p/n 1400-RM) for standard 19” racks is available for the TECSource, and supports the rack mount of one or two units in a 2U (3.5”) high opening. The rack mount kit provides sufficient clearance below the units for ventilation, so units can be rack mounted immediately above other equipment (no rack spacers required).
Page 9: Front Panel Operation
5235 TECSource User’s Manual · Page 9 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 three buttons on the front panel: Output, Menu, and the adjustment knob.
Page 10 Page 10 · 5235 TECSource User’s Manual Control Modes TECSource offers three control modes: constant temperature mode (T Mode), and constant resistance mode (R Mode), and constant current mode (Ite Mode). Changing the control mode is done through the menu by changing the Mode parameter to T Mode, R Mode, or Ite Mode.
Page 11 5235 TECSource User’s Manual · Page 11 Because 5235 TECSource uses a digital PID loop, it will always stabilize at the set point, and you will never have a temperature offset, which is different that most other temperature controllers. Using Limits TECSource supports three different types of limits: temperature, sensor, and current.
Page 12: Settings And Menus
Page 12 · 5235 TECSource User’s Manual Settings and Menus All parameters of the TECSource can be viewed and changed within the menu. 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.
Page 13 5235 TECSource User’s Manual · Page 13 Menu Description Factory Default PID I The integral term of the PID loop. Will only be 0.01 available if Gain is set to PID. PID D The derivative term of the PID loop. Will only be available if Gain is set to PID.
Page 14 Page 14 · 5235 TECSource User’s Manual Menu Description Factory Default Tol Temp Tolerance temperature is a temperature band 0.1°C (in °C) around the set point temperature. When the actual temperature is within this band for longer than the Tol Time setting, then the unit is considered to be in tolerance.
Page 15 5235 TECSource User’s Manual · Page 15 Menu Description Factory Default Sys Menu System Settings Menu Disp Mode Display mode, which is used to control the Normal layout on the main screen. Normal will display four values, typically the set point temperature, read back temperature, current, and voltage.

Page 16 · 5235 TECSource User’s Manual Rear Panel In addition to the input power connector described above, there are three connectors on the rear panel of the TECSource: Output connector, USB connector, and RS232 connector. TECSource Rear Panel TEC Output Connector The Output connection is a female DB-15, and has the following pin-out: DB-15 Pin Description...

5235 TECSource User’s Manual · Page 17 Description Receive Transmit Ground 1,4,6 Commoned together Commoned together No connection Shell Earth ground RS232 Connector (DB-9 Male) For more information on using the RS232 interface, see the Computer Interfacing Manual which is included on the CD that accompanied this product. Connecting to the TECSource Arroyo Instruments carries two cable assemblies specifically designed for connecting the TECSource to temperature controlled fixtures or devices.
Page 18: Remote Mode Operation
Page 18 · 5235 TECSource User’s Manual Adjusting the Mount setting to User Defined removes all software limits, allowing unrestricted operation of the TECSource. Remote Mode Operation Remote mode operation is when the TECSource is being controlled by a computer over the USB or RS232 interfaces. When in remote mode, the TECSource behaves differently, preventing you from affecting the operation of the instrument.
Page 19: Working With Thermistors
5235 TECSource User’s Manual · Page 19 Working With Thermistors TECSource is designed to work with negative temperature coefficient (NTC) thermistors, such as the BetaTHERM 10K3A1 thermistor used in the LaserMounts. A thermistor works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’).
Page 20: Resistive Heaters And Heat/Cool Only Modes
Page 20 · 5235 TECSource User’s Manual The typical setting is 100μA, but your application will determine the actual needs. The Steinhart-Hart Equation As can be seen from the temperature versus resistance graph above, resistance varies inversely with temperature in a non-linear fashion. This relationship can be accurately modeled by polynomial equations, and one such being the Steinhart- Hart equation: The coefficients A, B, and C can usually be obtained from the thermistor...
Page 21: Compensating For Cable Resistance
5235 TECSource User’s Manual · Page 21 To manually adjust the PID, start by changing the I and D values to zero, and adjust the P value so that it reaches the set point as quickly as possible without overshooting the set point an unacceptable amount. Gradually increase the I value until the set point is achieved without oscillation.
