Selection of Analog Output Response Time
The Gauge Setup screen now has a line for selecting between a FAST or SLOW analog
output response time. When FAST is selected, the analog output response time is ~10
msecs, while the SLOW selection is ~ 250 msecs. The original XGS-600 release was always
slow. The fast mode is useful for applications where you want to log and inspect the events
that lead up to a fast set-point release or if they want to use the analog output for their own
interlock purposes and bypass the XGS-600 set point outputs. When the fast response time
is selected, the signal is necessarily somewhat noisier and less accurate than the slow
version.
The default settings are FAST for the IMGs and SLOW for hot filament, rough gauges and
gauges connected to the analog board.
System Setup Screen
Use this screen to set values for overall system operation.
To open this screen select SYSTEM SETUP on the Sensor Setup screen.
Figure 3-7 System Setup Screen
UNITS Select: Torr (default), Pascal or mbar. Once the units are changed,
the values throughout the system are updated to the new units.
SETUP LOCKOUT Toggle this to ON to make all fields on the SYSTEM SETUP and
SENSOR SETUP screen display-only (except for this field). This pro-
vides a layer of security to prevent inadvertent changes.
AUTO FILAMENT
ADVANCE (HFIG
Boards) For two-filament HFIG sensors, if Auto Filament Advance is
selected, Filament 2 is automatically engaged if Filament 1 has an
open filament error (NO FIL1). FIL2
ON then appears on the main
screen. Auto filament advance can occur when emission is first
turned on or during gauge operation. Auto advance does not
advance from Filament 2 to Filament 1. If an open filament error
occurs on Filament 2, instead the
NO FIL2 error appears and emis-
sion is turned off.
