Adjustments and Problems
The only user serviceable adjustment is the LCD contrast (see below). There
are no user serviceable components inside the instrument enclosures.
WARNING
There are potentially lethal voltages inside this
instrument’s enclosure. The source of these voltages
is from the line power and also from the system and
Aux I/O connections.
6.1 LCD Contrast Adjustment (XTC/2 only)
The LCD contrast is optimized for "above the display" viewing angles and
adjusted at the factory. It may be better optimized on site for use in positions
that place the instrument in extreme viewing angles.
To adjust for best possible contrast in the installed position use a potentiometer
adjustment tool or small common screwdriver carefully inserted through the
front panel (see
section 2.4 on page 2-10 , Item 11) and turn clockwise or
counter clockwise to obtain the best possible display contrast for your viewing
angle.
6.2 Error Messages
The following error codes are generated and displayed by the XTC/2.
6.2.1 Powerup Errors
ERR 0 . . . . . Film parameters lost on power up. This may be cleared by
pressing any key. All film and layer parameters will have to be
re-entered.
ERR 9 . . . . . Process data lost on power up. This is cleared by pressing any
key. Automatic process recovery will not be possible.
NOTE: Upon detection of power failure, all current layer and process data is
normally saved for process recovery use on subsequent deposition
system recovery.
