  • Page 21: 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, the environment, and the materials being treated in the oven, as well as to prevent damage to the oven.

  • Page 22: Theory Of Operations

    OPERATION HEORY OF PERATIONS Heating The oven temperature controller stores an operator-selected constant temperature set point. When powered, the oven heats the chamber atmosphere to the set point. The controller board is wired to a solid-state temperature probe located in the chamber on the rear wall. When the controller detects that the chamber temperature has dropped below the temperature setpoint, it pulses power to the heating elements.
  • Page 23 OPERATION Vents – Intake and Exhaust The oven is provided with an intake vent and exhaust vent that may be opened or closed using dampener slides located on the vents. The dampeners are intended to be opened after the heat treatment or bake out phases of an application are complete.

  • Page 29: Data Port

    OPERATION 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 30: Auto Tuning

    OPERATION UNING The auto tuning function runs the oven for a period of hours to optimize the controller PID parameters when running the oven with a large volume or mass of product in the oven chamber. PID optimization is intended to be used if the oven temperature is lagging, overshooting, or failing to achieve the setpoint under the above conditions.

  • Page 31: Gn 2 Purge Option

    OPERATION Note: The GN purge is not intended to enhance air exchange rates or ventilation. URGE PTION TFO ovens may be ordered with a gas nitrogen purge option. This is a special quote build and must be requested at the time of purchase, prior to construction of the oven.
  • Page 32 OPERATION Set Up Close the oven vents. Failure to close the vents compromises the integrity of the purge. a. Close both the intake and exhaust vents on the top of oven. b. Close the access port on the back of the oven. All 3 vents fully closed.
