This part of the instruction manual contains every specific information on how to
operate a temperature module TED8xxx. A general description is followed by
explanations of how to operate the unit manually. You will also find every information
about remote control via the IEEE 488 computer interface.
!Attention!
This manual contains “WARNINGS” and “ATTENTION” label in this
form, to indicate dangers for persons or possible damage of equip-
ment.
Please read these advises carefully!
NOTE
This manual also contains “NOTES” and “HINTS” written in this form.

1.1 Safety
Temperature module TED8xxx / page 1
1 General description of the temperature module TED8xxx
1.1 Safety
!Attention !
All statements regarding safety of operation and technical data in
this instruction manual will only apply when the unit is operated
correctly.
Before applying power to your PRO8000 (-4) / PRO800 system, make
sure that the protective conductor of the 3 conductor mains power
cord is correctly connected to the protective earth contact of the
socket outlet!
Improper grounding can cause electric shock with damages to your
health or even death!
Modules may only be installed or removed with the mainframe
switched off.
All modules must be fixed with all screws provided for this purpose.
Modules of the 8000 series must only be operated in the mainframe
PRO8000, PRO8000-4 or PRO800.
All modules must only be operated with duly shielded connection
cables.
Only with written consent from Thorlabs may changes to single
components be carried out or components not supplied by Thorlabs
be used.
This precision device is only dispatchable if duly packed into the
complete original packaging including the plastic form parts. If
necessary, ask for a replacement package.

1.1 Safety
Temperature module TED8xxx / page 2
!Attention !
Semiconductor laser modules can deliver up to several 100mW of
(maybe) invisible laser radiation!
When operated incorrectly, this can cause severe damage to your
eyes and health!
Be sure to pay strict attention to the safety recommendations of the
appropriate laser safety class!
This laser safety class is marked on your PRO8000 (-4) / PRO800
plug-in module or on your external laser source used.
!Attention !
Mobile telephones, handy phones or other radio transmitters are not
to be used within the range of three meters of this unit since the
electromagnetic field intensity may then exceed the maximum
allowed disturbance values according to EN 50 082-1.

1.2 Warranty
Temperature module TED8xxx / page 3
1.2 Warranty
Thorlabs GmbH warrants material and production of the TED8xxx modules for a
period of 24 months starting with the date of shipment. During this warranty period
Thorlabs GmbH will see to defaults by repair or by exchange if these are entitled to
warranty.
For warranty repairs or service the unit must be sent back to Thorlabs GmbH
(Germany)or to a place determined by Thorlabs GmbH. The customer will carry the
shipping costs to Thorlabs GmbH, in case of warranty repairs Thorlabs GmbH will
carry the shipping costs back to the customer.
If no warranty repair is applicable the customer also has to carry the costs for back
shipment.
In case of shipment from outside EU duties, taxes etc. which should arise have to be
carried by the customer.
Thorlabs GmbH warrants the hard- and software determined by Thorlabs GmbH for
this unit to operate fault-free provided that they are handled according to our
requirements. However, Thorlabs GmbH does not warrant a faulty free and
uninterrupted operation of the unit, of the soft- or firmware for special applications nor
this instruction manual to be error free. Thorlabs GmbH is not liable for consequential
damages.
Restriction of warranty
The warranty mentioned before does not cover errors and defects being the result of
improper treatment, software or interface not supplied by us, modification, misuse or
operation outside the defined ambient conditions (refer to the PRO8000 (-4) /
PRO800 mainframe operation manual) stated by us or unauthorized maintenance.
Further claims will not be consented to and will not be acknowledged. Thorlabs
GmbH does explicitly not warrant the usability or the economical use for certain
cases of application.
Thorlabs GmbH reserves the right to change this instruction manual or the technical
data of the described unit at any time.

1.3 Features
Temperature module TED8xxx / page 4
1.3 Features
1.3.1 Safety measures for the TEC element
To protect the connected TEC element the laser diode control system PRO8000 (-4)
/ PRO800 includes the following protection circuits:
• Limit of the TEC current (hardware- and software limit) in all operating
modes
Protection against thermal destruction.
• Protection of the sensor
Protection against use of incorrect temperature sensors / protection against line
interruption of the temperature sensor.
• Contact protection of the TEC element (open circuit)
Protection against cable damage, bad contact or TEC element with too high
resistance.
The output remains switched on since a wrong TEC element is still cooling and
can protect the laser diode.
• Separate on/off function for each module
Protection against operating errors.
• Control LED for TEC current on
Protection against accidental turning off the cooling.
• Separate over-temperature protection for each module
Protection against thermal failure of the module.

1.3 Features
Temperature module TED8xxx / page 5
• Mains filter
Protection against line transients or interference’s.
• Line failure protection
In case of power failure or line damage the temperature control and the laser
must explicitly be switched on anew since it cannot be taken for granted that all
components of the measurement set-up are still working faultlessly.
• Key-operated power switch
Protection against unauthorized or accidental use.
• LabVIEW®- and LabWindows/CVI®-driver
For the PRO8000 (-4) / PRO800 Thorlabs GmbH supplies LabVIEW®- and
LabWindows/CVI®-drivers for MS Windows 32.

1.3 Features
Temperature module TED8xxx / page 6
1.3.2 General functions
The temperature modules TED8xxx , TED8xxx-PT and TED8xxx-Kryo operate
similar, however they differ regarding maximum current, accuracy and resolution.
# (Refer to chapter 1.4, "Technical data" on page 7)
All normal modules have an input for IC temperature sensors of the AD590/592 or
LM335 series as well as an input for thermistors. With thermistors two resistance
ranges can be used (maximum resistance 20kΩor 200kΩ).
The TED8xxx-PT has an input for thermistors and PT-100 sensors.
The TED8xxx-Kryo only has an input for a PT-1000 sensor (2 temperature ranges).
All necessary value settings are done by the mainframe operating elements (keypad
and rotational encoder) or via remote control by a computer. Only the TEC current
limit (hardware limit) has to be set manually as "absolute limit".
In an automated test set-up for different laser diodes no manual settings are
required.
The set values for the temperature or the thermistor resistance have 16 bits
resolution. The limit value for the TEC current (software limit) is set with 12 bit. The
read back of actual temperature and actual resistance has 16 bit resolution, the read
back of TEC current, TEC voltage and the limit for the TEC current (hardware limit)
15 bit plus sign.
The P-, I- and D-share of the analog control loop are set with three independent
12 bit D/A converters.
The built-in mains filter in the mainframe and the careful shielding of the transformer,
the micro processor and the module itself provides an excellent suppression of noise
and ripple.
