CHAPTER1 INTRODUCTION This manual contains operation, calibration and specification information for the LDT-5100. It is recommended that the user become thoroughly familiar with this information prior to operating the LDT-5100. If any of the following symptoms exist, or are even suspected, remove the LDT-5100 Temperature Controller from service. Do not use until trained service personnel can

INTRODUCTION CHAPTER 1 Product Overview Product Overview The LDT-5100 Temperature Controller is a device which, when powered by the appropriate supply, measures the temperature dependent resistance of a thermistor. Using this resistance as feedback, it stabilizes temperature by driving current to a thermoelectric (TE) module. The TE drive for the LDT-5100 is bipolar (positive current to cool; negative current to heat). This allows for highly stable temperatures and fast settling times. Desi

CHAPTER2 OPERATION See Figure 2.1 for location and identification of control connectors and jumpers. Thermistor Resistance Set Point Two methods of thermistor R set point control are provided in the LDT-5100; internal resistor or external resistor. A jumper, “RESISTOR SEL”, (J6) is used to select which resistor is used as the set point reference for the control loop. (A jumper on the left an

OPERATION CHAPTER 2 Thermistor Current Source Thermistor Current Source For a greater range of temperature sensing, two current sources are provided on the LDT-5100; 100 µA and 10 µA. Each source is selectable on the “THERMISTOR CURRENT” jumper (J5). The default setting from the factory is 100 µA. Note: If the jumper is removed, the 100 µA current source (default) is selected. The choice of current source will depend on the thermistor sensor used. Please refer to LX Lightwave Application No

OPERATION CHAPTER 2 Measurement/Control (J2) Output Monitors The LDT-5100 has two buffered output monitors present on the measurement / control connector (J2). These monitor the actual thermistor resistance and I TE (TE drive current). Thermistor Monitor The thermistor monitor (pin 10) provides an output voltage which is proportional to the thermistor sense resistor value. The transfer function with the 100 µA thermistor current range selected is 10k Ω/V and with the 10 µA thermistor current

OPERATION CHAPTER 2 LED Indicators supply voltage, this threshold is not a fixed value. Under normal operation (with a low impedance TE), the control line will be in a high impedance state. Output On/Off (pin 2) This control line indicates if the TE output is on (driving current to a TE load). A ground at this control line indicates that the output is off and no current is being driven through the TE modules. LED Indicators Pads are located on the LDT-5100 PCB to allow direct connection of in
