LCD contrast/bias: The optimal viewing is designed for perpendicular to about 45
° up and about 45° from
perpendicular to either side. Within a few minutes of powering the unit on, there will be some thermal drift
effecting color but this should be relatively unnoticeable. If, however, the unit will be in an environment
having elevated ambient temperatures (above 30
° Celsius), the LCD contrast/bias should be set to low
through menu programming (Main/Executive/System Configuration menus).
Graphical Display: Although no hardware other than the LCD display is associated with this item, it needs
to be setup. Three film parameters need to be programmed: Plot Vert Scale Volts, Plot Horiz Scale H, Data
Plot Type. The graphical display, as the name implies, displays, in graph form: rate deviation, rate or
power.
Rack Mounting: Rack mounting ears, extenders and screws are supplied with the STC-2000A for the
purpose of mounting the unit in a standard rack. Don't block ventilation slots or place above heat sources.
Rubber Feet: Rubber feet are not supplied with the STC-2000A. The anticipated usage of the product is
within a rack. If, however, in the unlikely case where the usage will be on a shelf, table or some other flat
surface, rubber feet should be used to prevent sliding with the possible resultant damage. They should be
of the type that sticks on the bottom of the unit. These can be purchased cheaply at many retail outlets.
The waxed paper is first removed from each foot. The foot is then applied to the bottom of the STC-2000A
such that they are placed in each corner an inch from the 2 corner surfaces. Subsequently, if the unit will
be rack mounted, remove the rubber feet.
System Hardware Connections: Except for the generalized previous descriptions, complete system
hardware setup is beyond the scope of this manual. Consult the manuals for each of the components in the
system. The sum of the manuals is less than the whole: Be forewarned that the general information
contained herein is meant as an overview of the system only, an overview to describe how the STC-2000A
integrates with the other components in the system and some of its' typical usage's. The information
presented here does not adequately describe the many hazardous situations that could occur brought about
by the incorrect constellation of valve states, temperatures, pressures and voltages. The system needs to
have safety provisions should inadvertent human intervention cause changes or should a power failure of
any or all parts of the system occur. Safety concerns include electrocution and explosion.

Synopsis:
Select mode: sequencing/runtime, sequencing/test, non-sequencing/runtime, non-sequencing/test.
Optional selects: manual mode and test mode. Select memory configuration: factory, purged, as-is.
Program system parameters. Program film parameters (for a single film or multiple films) and process
steps. Set active process. Select crystal. Start process.
The versatility of the STC-2000A translates into many modes, parameters and configurations all of which
arrive from the factory in default states. Except for the Input card hardware configurations (uses jumpers),
all modes, parameters and configurations are user programmable by menu. The VAR or end user must
tailor the unit to work with specific hardware for the desired deposition process.
The VAR or end user must
tailor the unit to the specific hardware and deposition process at hand .
Runtime mode is the general name for the mode used for the deposition process whose screen can
always be brought forth from any menu screen by pressing the fixed front panel key labeled STATUS.
A second press of the STATUS key while the RunTime screen is displayed will invoke a screen showing the rate,
power and thickness in large characters. A third press of the STATUS key while the RunTime screen is displayed will
invoke a screen showing, among other elements, active control output channel[s], pocket number[s] and power %
expended on each. A forth press of the STATUS key beginning when the RunTime screen was displayed will invoke a
screen showing, among other elements, active sensor channels and their states, rates, thickness', stability's and crystal
lives. This forth screen can be used to fail or reinstate (re-verify) a crystal. Zero thickness at this level is used for
tooling setup or diagnostics and has no effect on the deposition thickness.]
