Failure to perform intended measurements or functions If necessary, return the instrument to ILX Lightwave, or authorized local ILX Lightwave distributor, for service or repair to ensure that safety features are maintained. All instruments returned to ILX Lightwave are required to have a Return Authorization Number assigned by an official representative of ILX Lightwave Corporation prior to shipping the instrument.
This section describes the safety symbols and classifications. Technical specifications including electrical ratings and weight are included within the manual. See the Table of Contents to locate the specifications and other product information. The following classifications are standard across all ILX Lightwave products: Indoor use only ...

Options and accessories Specifications Safety Considerations If any of the following symptoms exist, or are even suspected, remove the LDT-5416 from service. Do not use the LDT-5416 until trained service personnel can verify safe operation. Visible damage ...
This is achieved by modulating the current through a thermoelectric load and continuously monitoring the feedback signal generated from a thermistor temperature sensor. The linear output stage of the LDT-5416 offers the low current noise necessary to achieve the temperature stability required in most low-noise and frequency-stabilized laser applications.

With the LDT-5416 connected to an AC power source, pressing POWER supplies AC line power to the instrument. After power-up, make sure that the OUTPUT is off (LED unlit) until you have configured the instrument for your application.
Fan (+) Fan (-) Figure 2.1 – LDT-5416 Output Connector The TE drive current is available at the 15 pin connector. Pins 1 and 2 and pins 3 and 4 are tied together internally. Pins 1 and 2 source current while cooling and sink current while heating. Pins 3 and 4 sink current while cooling and source current while heating.
GAIN: A single turn potentiometer which adjusts the control loop gain. This adjustment affects the slew rate and settling time of the LDT-5416 when reaching the desired setpoint. If the GAIN is set too low (counter-clockwise), the LDT-5416 will take longer to reach the desired setpoint. If the GAIN is set too high (clockwise), the LDT-5416 may oscillate around the desired setpoint.
Rotating the knob clockwise in 10/100 µA mode will increase the resistance (decrease the temperature) and rotating counterclockwise will decrease the resistance (increase the temperature). When the LDT-5416 is in °C LINEARIZED FOR 10k rotating the knob counter clockwise will increase the temperature and when rotating clockwise will decrease the temperature.
SNS OPEN LED indicator is illuminated. • TEC OPEN – If the connected TEC exceeds the rated voltage of the LDT-5416 the output will be disabled and the TEC OPEN LED will be illuminated.
LDT-5416. Thermistor resistance and voltage are related through Ohms Law (V = I x R). The LDT-5416 supplies current to the thermistor, either 10µA or 100µA, and as the resistance changes, a changing voltage signal is available to the thermistor inputs of the LDT-5416.

Figure 2.3 Thermistor Temperature Range Temperature from Resistance The LDT-5416 Thermoelectric Temperature Controller primarily displays resistance of the thermistor; several methods can be used to convert the resistance to a temperature. Resistance-Temperature Conversions Charts - Most thermistor manufacturers will supply a resistance - temperature (R-T) chart for their thermistors.

Linearized Thermistor Mode – For users wanting to display a calculated temperature without using one of the methods above the LDT-5416 has a unique mode that when selected will display and control to a calculated temperature. To use this mode the LDT-5416 sensor select switch must be set to °C LINEARIZED FOR 10k.
1. Plug the LDT-5416 into an AC power source within the specified range of the instrument. 2. Turn on the LDT-5416 by pressing and releasing the power switch to latch it to the on position. The output will be disabled at power up and the unit display mode will power up in the same mode which existed when the power was last shut off 3.
Chapter 3: Troubleshooting This chapter will help you resolve any problems you may experience with your LDT-5416. If you need additional help, please contact ILX Lightwave Customer Service. ILX Lightwave Corporation provides in-house calibration services for ILX instruments. International customers may contact our service centers for regional calibration support. Most ILX instruments, including the LDT-5416 require yearly calibration to ensure performance to published specifications.
This section lists some common problems and corrective actions. In the event that the corrective action does not resolve the problem, please contact ILX Lightwave.
