  • Page 3: Section 1. Preface

    In heating devices of BAS manufacture, the temperature sensor is built into the instrument. To control other devices, a universal probe (part no.

  • Page 4: Section 2. Power Requirements

    115V or 230V operation is on the back chassis panel. The line voltage must be selected before applying power to the controller. A 3-prong power cable on the LC-22C must be connected to a standard, grounded power outlet for safety. If the instrument is operated from a power outlet without a ground connection, an appropriate adapter should be used and the ground connection of this adapter should be securely fastened to an earth ground.

  • Page 5: Section 3. Installation

    Plug the cable leads from the stainless steel UNIVERSAL PROBE (EW-8116) into the red, yellow, and black jacks on the back panel of the LC-22C labeled “PROBE 1" or ”PROBE 2". The black jack provides grounding for the instrument and must be connected for safety purposes.
  • Page 6 If you plan to use several different styles of column endfittings, it is best to use removable plastic fittings. BAS recommends a 2-piece PEEK finger-tight seal as provided in BAS part no. MR-4409 (this includes a nut and ferrule). One piece plastic fittings tend to loosen at higher temperatures.
  • Page 7 If you are installing the LC-23C as an upgrade to a BAS electrochemical detector or BAS 480 Liquid Chromatograph, and already have a cell preheater installed in the CC-5, you may wish to remove it.

  • Page 10: Section 4. Operation

    Using the “SETPOINT HEATER 1" knob, select the desired temperature, which is between ambient and 99.9°C. Turn off the main power to the LC-22C and connect the heater to “HTR-1" and the red, yellow and black probe plugs to the same color jacks of ”PROBE-1" on the back panel.
  • Page 11 ”PROBE 2" and observe the color code used on the jacks. Turn the main power on to the LC-22C. Rotate the display selector knob to “SENS 1" or ”SENS 2", depending upon which channel is being used for measurement. The digital display will read the probe temperature in degrees C.

  • Page 12: Section 5. Safety And Maintenance Checks

    Section 5. SAFETY AND MAINTENANCE CHECKS The LC-22C, LC-23A, LC-23C and cell preheater are all essentially maintenance free instruments. BAS does advise that you attempt to keep these pieces in good condition by following these suggestions: Avoid corrosive laboratory environments.
  • Page 13 If your unit fails either step 3 or 4, please contact the BAS Service Coordinator to return both the LC-22C and the probe used to make these tests for service. Do not return any equipment without first obtaining a Return Authorization number from BAS.
