  • Page 5: Introduction

    Introduction The CL-100 Bipolar Temperature Controller from Warner Instruments is a versatile and simple to use thermal control device.This single channel, automatic controller capable of accurately maintaining a Peltier device between 0° and 50°C. The unit will also maintain a resistive heater from ambient to +65ºC.

  • Page 6: Nomenclature

    Nomenclature Text Conventions This manual refers to instrument controls at two functional levels; specific controls and settings of these controls.To increase readability, we employ the following text conventions. Since our goal is to provide clarity rather than complexity, we welcome any feedback you may wish to provide. •...

  • Page 7: Control Description

    Control Description Front Panel A schematic of the face panel of the CL-100 is shown below. Important components are identified by letter (A-H, J-N). Refer to this diagram as an aid in identification of the described components. Power Switch (Item A) Supplies power to the CL-100.

  • Page 8: Cooling Mode Switch (Item C)

    Control Description (Cont’d) Cooling Mode Switch (Item C) Selects between Automatic or Manual operational modes, or center select for off. Thermistor Recorder Outputs (Items D, E) BNC connectors are provided to send thermistor readings to a data acqui- sition system or chart recorder. CONTROL TEMP OUT (Item D) reports the actual temperature of the feed- back thermistor situated within the heater/cooler device being used.

  • Page 9: Manual Voltage Control (Item K)

    Control Description (Cont’d) Manual Voltage Control (Item K) Used to manually adjust the voltage output to the heater/cooler device.The associated GREEN LED is on when the INTERNAL/EXTERNAL SELECT CONTROL (Item J) is set to internal, and the COOLING MODE SWITCH (Item C) is set to manual.

  • Page 10: Rear Panel

    Control Description (Cont’d) Rear Panel A schematic of the rear panel of the CL-100 is shown below. Important components are identified by letter (P-T). Refer to this diagram as an aid in identification of the described components. External Volts Set (Item P) Input BNC for the application of a specified voltage to be applied to the heater/cooler being controlled.
  • Page 11 Control Description AC Conversion ATTENTION PLEASE READ BEFORE APPLYING POWER TO YOUR UNIT!! The unit has been set to be used with 120 VAC. If the VAC needs to be changed to 220VAC, enclosed you will find a kit (power cord (1) and fuses (2)) to be used to convert the unit from 120VAC to 220 VAC.

  • Page 12: Setup

    Setup The CL-100 has been designed primarily to drive Warner’s expanding line of Peltier driven Heater/Coolers.However,the device is also capable of supplying power to Warner’s full line of resistive heaters (e.g., Series 20 Heater Platforms, In-line Solution Heaters, etc.).The instrument will auto-detect when a resistive heating device has been attached and will disable cooling commands.

  • Page 13: Operation

    Operation The main use of a heater/cooler control device such as the CL-100 is to maintain a constant bath temperature with minimum deviation from a set temperature. This is usually achieved by using a thermally controlled cham- ber/platform or in-line solution heater, or a combination of both. NOTE: Refer to the front and rear panel schematics on pages 6-9 for orien- tation of the CL-100 controls.

  • Page 14: Manual Mode

    Operation (Cont’d) Manual Mode In manual mode, the MANUAL VOLTAGE control (Item K) is used to set the output voltage to a fixed value. In manual mode, the SET TEMPERATURE control (Item H) is disabled, as is the feedback system of the CL-100. Operation is again straightforward.

  • Page 17: Service Notes

    Warranty & Service (Cont’d) Service Notes Please refer all questions regarding service to our Engineering Department. A) If the instrument POWER light fails to light, check the fuse at the rear panel (located in the black POWER INPUT MODULE). If the fuse is found to be defective replace it with a 5x20 mm, 0.8 A, slow-blow fuse (0.4 A for facilities using 220-240 V line voltages).
