Section 4 Control, Indicators and

Connectors

Before putting the Oven into operation, the user should become
thoroughly familiar with the location and function of all controls,
indicators, and connectors. Most are clearly labeled and located on or
below the front panel, with the exception of the two (PURGE and
VACUUM) hose connectors, which are located on the lower right side of
the oven. A set of vacuum pump auxiliary contacts and the
temperature/vacuum recorder output connectors are located on the rear
side of the control board. See Auxiliary Pump Contacts for instructions on
accessing these connectors.

The control panel consists of two 14-segment alphanumeric displays, six
indicator LEDs, four keypads, and an ON/OFF toggle. The VACUUM
and PURGE valves are located just beneath the control panel. The list
below gives a more detailed explanation of each.

Day/Time Display

A four character alphanumeric readout that alternately displays the day
of the week and time of day in 5-second intervals.

Temp/Vacuum Display

A four character alphanumeric readout that alternately displays the tem­perature (°C) and chamber pressure (in Hg) in 5-second intervals.
