Model 3100-1L Temperature Controller User Manual 1
1 Overview
The Model 3100-1L Temperature Controller is a precision control unit which provides
closed loop temperature control of Peltier thermo-electric coolers/heaters at the <+/-
0.001 °C level. The controller is a microprocessor based unit with an Ethernet inter-
face which communicates through TCP/IP. The controller is optimized for use with L-1
Standards and Technology Inc.’s line of temperature controlled detectors which include
silicon photodiode trap detectors, single element silicon photodiodes, InGaAs pho-
todiodes, extended-IGA photodiodes and a 3-detector Windowed Integrating Sphere
Assembly that covers from 350 nm to 2400 nm in a single device. The Model 3100
comes in 3 versions: 1L – a low power model for single detectors; 3L – three channel
model to operate the detectors in the Integrating Sphere Detector, and 1H – which is a
higher power single channel model used for custom temperature control applications.
The temperature controller, when sold as part of a detector package, is precongured
to operate the detector automatically. All that is required is to connect the cabling and
power the unit on. The controller will then maintain the preset temperature on the
detector. If you wish to log data to a computer or change settings then an Ethernet
connection is required. The temperature controller is delivered with a LabVIEW virtual
instrument driver that will allow control and data logging from the controller using the
customer supplied LabVIEW program.

4 Setup
1 Make sure the Model 3100 Temperature Controller is turned off by unplugging its
power supply.
2 Connect the Model 3100 Temperature Controller to a L-1 temperature controlla-
ble detector using the supplied One Channel Cable. The four pin LEMO connec-
tor of the One Channel Cable connects to the back of the detector and the DB-15
connector to the back of the temperature controller.
3 Power on the temperature controller by connecting the DB-9 “DC Power” connec-
tor of the power supply to the “DC Power” connector on the back of the tempera-
ture controller and then plugging the power supply into a wall outlet that provides
100-240 VAC, 50/60 Hz power. L-1 recommends using a surge protector
between the equipment and the wall outlet.
4 The temperature controller will immediately boot up and several screens of infor-
mation will appear on the LCD screen before the temperature set point and cur
rent temperature reading appears.
First Screen:

Second Screen:
SWver1.1.1c.1t (code version; actual code version may vary)
User Name (actual user name may vary)
Third Screen:
IP Address:
10.0.1.10 (example IP address is used here; actual IP address may vary)
5 The nal screen will provide information on the set point (temperature setting)
and current temperature. The temperature controller is preprogrammed to auto-
matically control detector temperatures at a specic set point depending on the
detector type.
6 If a change in set point is needed or if automated recording of the temperatures
is desired, connect the temperature controller to a computer using an Ethernet
cable (not supplied) and use the Model 3100-1L Temperature Controller Soft-
ware. Please refer to the software section of this manual for further details.
NOTE Turn off power to the temperature controller before starting the below steps.

5 Software
The Model 3100-1L Temperature Controller can be controlled with computer software
written in LabVIEW. Using the provided software with LabVIEW 2012 or higher, a
user can modify the temperature set point, change the IP address and user name
of the temperature controller, modify various parameters and record data (including
temperatures) to le.
Starting the Model 3100-1L Temperature Controller Software
You must have LabVIEW 2012 or higher installed to run the provided software.

Running the Model 3100-1L Temperature Controller Software
1 Click the Run button (button with the white arrow in the upper left of the screen
underneath the edit menu of the software) of the Model 3100-1L Temperature
Controller v1.vi. The Run button starts LabVIEW running.

2 Verify the IP address on the screen and if needed, change it to match the tem-
perature controller’s IP address shown on the LCD screen during system boot up.
The preset IP address of the unit is also labeled on the top of the Model 3100-1L
Temperature Controller unit upon shipment.
3 The default folder path shown can be changed if desired. If it does not already
exist, the folder will be created when the program runs.
4 If the Model 3100-1L Temperature Controller has just been powered on, please
wait one minute after the temperature reading appears on the LCD screen before
continuing to the next step to allow the unit to fully power on.
5 Click the green Start Communication button to initialize communication with the
temperature controller. It may take up to 5 seconds for communication to be
established.

Model 3100-1L Temperature Controller User Manual 9
7 When communication is established, the Detector Temperature Control and
Manual Commands buttons, which were unavailable during connection estab-
lishment, become available. The IP Address and Folder Path controls become
unavailable as they cannot be changed after communication is established.
6 If communication fails, a pop-up window will appear stating that the connection
failed and giving instructions to restart the program after checking power, Eth-
ernet connection, and IP address. Pressing the OK button will close the pop-up
window and stop the Model 3100-1L Temperature Controller v1.vi.

8 Clicking either the Detector Temperature Control or Manual Commands button
opens the corresponding program’s front panel and starts the vi and program
running (Detector Temperature Control v1.vi and Manual Commands v1.vi
respectively). When either of these two programs is running, the Stop Communi-
cation button and the program buttons are unavailable within the Model 3100-1L
Temperature Controller v1.vi. To switch between these two programs, close the
current program using the Stop Program button and then click the other program
button in the Model 3100-1L Temperature Controller v1.vi.
9 Use the Detector Temperature Control v1.vi to monitor data and control the user
adjustable parameters.

Stop Program Button
Stops the program and closes the program window.
Pause Button
Pauses the program.
Target Temp (ºC)
Sets the set point (target temperature) in degrees Celsius.
Minimum: -28.000; Maximum: 35.000.
Control Mode
If set to 0, the DAC value is set to the Open Loop Setting value.
If set to 1, the DAC value is controlled by the PID Settings.
Open Loop Setting
Sets the digital DAC value using a 16-bit digital number between 0 and
65535 which corresponds to a voltage from 0 to 5 volts. The Control Mode
must be set to 0 for the DAC value to be set to the Open Loop Setting
value.
PID Settings
The temperature controller DAC value can be controlled using a PID
control algorithm in which the DAC setting is automatically varied based
on the PID settings and the temperature error. The temperature error is
the difference between the set point (target temperature) and the current
detector temperature.
