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 The oven temperature controller stores an end-user-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 set point, it pulses power to the heating elements. - Page 25 OPERATION Vents: Intake and Exhaust The oven is provided with an intake vent and an exhaust vent. These may be opened or closed using dampener slides located on the vents. The vents are intended to be opened after the heat treatment or bake-out phase of an application is complete.

Page 27: Set The Over Temperature Limit
OPERATION ET THE EMPERATURE IMIT Note: Test the OTL system for functionality at least once per year. Failure to set the OTL voids the manufacturing defect warranty if over temperature damage occurs. This procedure sets the mechanical heating cutoff to approximately 10˚C above the chamber temperature. -
Page 28: Over Temperature Limit Activation
OPERATION EMPERATURE IMIT CTIVATION Possible causes: A user has set the Over Temperature Limit below the current set point. • This can be an issue when running heating profiles. The most common cause is the OTL being set to a temperature lower than the highest set point of a profile. An external heat source or heat source inside the chamber is causing the chamber air •... -

Page 30: Venting The Exhaust Port
OPERATION ENTING THE XHAUST Optional: The oven does not require venting to operate. However, evacuating exhaust out of the workspace can help prevent elevated ambient temperatures and the buildup of unpleasant odors. Obtain flexible, non-insulated ducting. • Attach the ducting to the lip of the exhaust port on the top, right side of the oven. See the •... -
Page 31: Power Exhaust Blower
Leave the oven exhaust vent closed until it is time to turn on the blower. SHEL LAB offers an accessory forced-air power exhaust blower that can be mounted directly on the exhaust vent cover. The blower is self-cooling when powered and running. - Page 32 OPERATION Activating and Deactivating the Power Exhaust The power exhaust may be run during any step of a heating profile except the terminating step. To run the exhaust blower, change the option control parameter of the step from 0000 to 0100 while programming the profile.

Page 35: Calibrating The Temperature Display
MAINTENANCE ALIBRATING THE EMPERATURE ISPLAY Note: Performing an accurate calibration of the temperature display requires a calibrated temperature reference device. Please see the Reference Sensor Devices entry on page 7 for the minimum device requirements. Temperature calibrations match the temperature display to the actual air temperature inside the oven chamber. - Page 36 MAINTENANCE 5. The oven temperature must be stable in order to perform an accurate calibration. The temperature is considered stabilized when the oven chamber has operated with the doors closed at your calibration temperature for at least one hour with no fluctuations greater than the specified stability of the oven (see page 43).
- Page 37 MAINTENANCE Calibration continued Operations Menu Enter the Operations Menu. Push the Program buttons. Configuration Advance to Configuration. a. Push the Up arrow to advance to “ConF”. Input Enter the Configuration menu. a. Push the Program button. The “InP” Input option will be the first to appear in the menu.

Push the Program button to unlock the -3 Offset Entered Offset parameter and place it in its blinking adjustable mode.
- Page 39 MAINTENANCE Calibration continued Once the temperature has stabilized, compare the Reference Device* reference device and the oven display temperature readings. If the readings are the same or the difference • between the two falls within the acceptable range of your protocol, the oven is calibrated for Homepage temperature.
