The Operating Modes
The X
TRA
system is equipped with three operating modes:
• Automatic
• 1 Touch
• Manual
Each is described in the sections below.
Modes of operation influence the execution of the active protocol, affecting the transition between
phases and cycles.
The current operating mode can be set from the Protocol/Mode tab of the Menu Screen. The operating
mode may be changed while the machine is stopped (at the Ready Screen), or any time during a
cycle. Step-by-step instructions can be found in the section “Running a Case With the X
TRA
System” on
page 5-5.
Automatic
In Automatic mode the system recognizes the end of each phase and automatically switches to the
next phase without any intervention from the operator (Fill to Wash/Spill to Empty). By default, at the
end of each cycle the system displays the Ready Screen and does not begin a new cycle automatically.
Automatic mode is compatible with all protocols and can be switched to at any time.
While Automatic mode is active, the word “Automatic” appears in the status area of every screen.
If an intraoperative or postoperative protocol is selected (Pstd, Popt, Post-op and Pfat), then either or
both of the Continue and Autostart functions may be enabled in conjunction with Automatic mode. If
both Continue and Autostart are enabled, then Automatic mode behaves exactly like 1 Touch mode.
1 Touch
The 1 Touch operating mode is a shortcut to running the Automatic mode with both the Autostart and
Continue functions enabled. It is only available if processing with an intraoperative or postoperative
protocol (Pstd, Popt, Pfat or Post-op).
In 1 Touch mode, each cycle is started automatically (Autostart function), the system recognizes the
end of each phase and automatically switches to the next phase without operator intervention (Fill to
Wash to Empty), and the system starts a subsequent cycle automatically as long as sufficient blood
volume is available in the reservoir (Continue function).
While 1 Touch mode is active, “1 Touch” appears in the status area of every screen.
The 1 Touch mode will not be available if disabled in the current configuration (refer to
Chapter
8: Configuring Xtra
).
Although it is possible to disable the Autostart function when 1 Touch mode is selected, it is considered
exceptional. On the contrary, it is not possible to disable the Continue function when 1 Touch mode is
selected.
