CONTROL OVERVIEW
Touchscreen Display and Controls
The 15-minute automatic purge and pressurization cycle must complete before the oven operator
can turn on the touchscreen controller using the Power button. When powered, the touchscreen
controls heating in the oven chamber and displays the current chamber temperature and vacuum
pressure. It also provides access to the Settings and Timer menus.
The touchscreen controller and oven heating system immediately turn off if the purged safety
enclosures lose overpressure.
Units of Measurement:
The display can be set to show temperature in standard or metric units
of measurement. Vacuum can be shown in Torr, Bar, or Inches of Mercury. See page 96 for
information on how to change the units of measurement.
Heating Button
This button contains the word Start or Stop in it depending on whether the oven is heating or not.
Tapping the button when it shows START starts the oven chamber heating. Pushing the button
when it shows Stop stops heating in the oven chamber. While heating, a red heating icon will fade
in and out on the button. This indicates the oven is pulsing power to the chamber heating
elements.
Safety Interlock Reminder: The chamber must be vacuumed down below 76 Torr (0.1 bar)
before the oven will heat.
