  • Page 23: Operation

    OPERATION Safe operation of the oven is dependent on the actions and behavior of the oven operators. Operating personnel must read and understand the Operating Precautions in this section prior to operating the oven. The operators must follow these instructions to prevent injuries and to safeguard their health, environment, and the materials being treated in the oven, as well as to prevent damage to the oven.

  • Page 24: Theory Of Operations

    OPERATION HEORY OF PERATIONS Heating When powered, the TFO oven heats the oven chamber atmosphere to the current constant temperature set point. The oven can also be programmed with multi-step automated heating recipe profiles. When launched, a profile overrides the constant temperature set point. In its default setting, the oven resumes heating to the constant temperature set point after a profile completes or is aborted.
  • Page 25 OPERATION Exhaust Vent The oven is provided with an exhaust vent that may be opened or closed using the dampener slide located on the vent body. The dampener is intended to be opened after the heat treatment or bake out phases of an application are complete. Opening the dampener vent during a baking application may speed the rate of material drying depending on the nature of the sample material, outgassed byproducts, and ambient conditions.

  • Page 30: Data Port And Data Jack

    OPERATION ORT AND The 25-pin RS485 data port, located on the back of the oven, connects to the oven temperature controller. It is primarily intended for updating the controller software but can be used for data logging and graphical profile programming. Accessing the controller with a computer requires a 25- pin RS485-to-USB converter cable and driver software.

  • Page 31: Auto Tuning

    OPERATION UNING The auto tuning function runs the oven for a period of hours to optimize the controller PID parameters. This optimization is intended for use only if the oven temperature is lagging, overshooting, or failing to achieve the set point when large volumes or significant masses of product are present in the oven chamber Auto tuning will not allow the oven to exceed its maximum specified heating rates.

  • Page 32: High Exterior Temperatures

    OPERATION Note: Allow the oven to cool or use appropriate PPE and tools when adjusting the chamber gasket seating. XTERIOR EMPERATURES If the chamber gasket comes out of alignment, oven chamber air may be drawn into the insulating baffle spaces. This can result in heating of the oven exterior surfaces. If the oven is exterior is unusually warm or hot, push the chamber gasket inward along its entire length to restore the integrity of the seal.

  • Page 33: Operator Maintenance

    OPERATOR MAINTENANCE Warning: Disconnect the unit from its power supply prior to performing maintenance or services. Avertissement: Avant d'effectuer toute maintenance ou entretien de cet appareil, débrancher le cordon secteur de la source d'alimentation. LEANING If a hazardous material or substance has spilled in the unit, immediately initiate your site’s Hazardous Material Spill Containment protocol.

  • Page 34: Gaskets And Chamber Integrity

    MAINTENANCE ASKETS AND HAMBER NTEGRITY Periodically, inspect the door latch, trim, catch, and the gasket for signs of deterioration. Failure to maintain the integrity of the door system shortens the life span of the oven. These ovens use snap-in fiberglass chamber gaskets. The only tool required for swapping out these gaskets is a cutting implement for tailoring the length of the new gasket.
