4.9.4.1 CESAR Control Computer
The CESAR control computer is used for the following tasks:
—
to modify or to create recipes,
—
to define the recipe variables (process time, temperature, pressure, gas flows)
needed for recipe start,
—
to start, stop and cancel recipes,
—
to digitally control the temperature,
—
to control the gas flows,
—
to control the loading machine,
—
to communicate with the handling system (option),
—
to monitor alarm/abort levels (gas flows, temperature, pressure),
—
to control the temperature via cascade controller,
—
to carry out automatic profiling via cascade temperature control,
—
to store a nearly limitless amount of recipes,
—
to log user defined process data up to the capacity limit of the storage medium
(hard disk, NFS server PC),
—
to enable extensive testing of the running process (execution of individual process
steps, modification of variables, setting/resetting of breakpoints, etc.).
4.9.4.2 centrotherm Machine Safety (CMS)
The CMS system (option) is a fault indication unit. It monitors
—
the cooling water flow,
—
cooling system leaks,
—
the fuse of the main fan of the horizontal furnace,
—
the temperature in the heating zone,
—
the temperature on the outside wall of the heating cassette,
—
the temperature of the power electronics,
—
the temperature of the heating transformers.
The disturbances are displayed on the operating panel of the CMI user interface. The
system's response to a disturbance is configurable.
