* Heat Bath Fluid The heat bath fluid must be able to obtain and maintain the required contactor actuation and deactuation temperatures. For the temperatures required for the calibration procedure, silicone fluid must be used. Silicone fluid has a temperature range between 10° C (50° F) and 230° C (446° F). Silicone fluid can be purchased from Cole-Parmer by ordering G-01294-40. The fluid comes in a 3.8 Liter (1 gal) container.
Use extreme caution around heat baths with high temperature fluids. High temperature fluids can cause severe burns.
Calibration Procedure
Use the following procedure to test and calibrate the temperature contactors.1. If connected, disconnect the contactor from the power supply. Mark the terminal location and disconnect the three wires from terminals 1, 2, and 4.
High voltage electrical shock is possible. The contactor must be disconnected from the power supply and the wires disconnected from terminals 1, 2, and 4. Failure to follow this recommendation can result in serious bodily injury.
2. Locate and record the part number of the temperature contactor in Chart A. This will determine the actuation and deactuation temperatures. If the temperature contactor is used in extreme ambient temperatures there will be a scale deviation from the required actuation and deactuation temperatures. Refer to the "Calculating Scale Correction for Severe Temperature Applications" section in this Special Instruction.
Temperature Contactor
(1) Housing cover. (2) Housing cover screws. (3) Temperature probe. (4) Capillary tube.3. Loosen housing cover screws (2) and remove housing cover (1).4. Fill the heat bath unit with silicone fluid and heat it to approximately 5° C (10° F) below the actuation temperature setting. Do not immerse the temperature probe at this time.

(5). Lock screw. (6) Range spindle. (7) Range scale. (8) Differential spindle. (9) Differential scale.5. Loosen lock screw (5).6. Adjust range spindle (6) to a setting above the desired actuation setting determined in Step 2. Determine the setting by using range scale (7).7. Adjust the differential spindle (8) to the approximate mechanical differential temperature using differential scale (9). Mechanical differential temperature is the difference between the actuation and deactuation temperature settings.
Temperature Control Function For Actuation And Deactuation (specifically shown for 7C-3888 Contactor)
Adjusting Temperature and Differential Settings On The Temperature Contactor
This example shows the temperature set at 66° C with an 8° C differential setting. This results in a deactuation temperature of 58° C and actuation temperature of 66° C. (Refer to "Temperature Control Function For Actuation And Deactuation" illustration.)8. Fully immerse temperature probe (3) in the silicone fluid. Increase the heat bath temperature to the specified actuation temperature.9. When the actuation temperature has stabilized, very slowly turn range spindle (6) counterclockwise until the contact actuates. This will be accompanied by an audible "click".
When Contact Actuates, Terminals 1 And 4 Will Have Continuity10. Use a 6V-7070 Multimeter, or equivalent, to verify the actuation of the contactor. Check for continuity between
