This message remains displayed until the sampling arm is in the home position
and it is safe to open the door. The screen then displays the message that it is safe
to open the door (see
Figure 3-38 ).
The
Time
field counts down the amount of time remaining in which it is safe to
open the door. If you open the door, the sequence or schedule pauses. When you
close the door, the sequence or schedule resumes.
The timer continues counting down while the door is open. If the door is still open
when the timer reaches zero, the sequence is ended.
To cancel the
OPEN DOOR SAFETY
screen, press any front panel button. If the
door is open, a message cautions you that pressing a button again will end the
schedule.
Notes
•
When the AS is operating under computer control, the door can be opened
safely only when the sampling arm is in the home position and the
autosampler is idle. This can occur at various times in a program (for
example, after injection is complete, but before the next injection starts).
•
When the AS is operating under front panel control, the door can be opened
safely only when the sampling arm is in the home position and the status
displays
WAITING FOR CYCLE TIME TO EXPIRE
. The cycle time controls the
time between injections (see Section 2.7.5 and Section D.5.4 ). For most runs,
selecting a cycle time greater than 4 minutes provides an adequate wait period
between each injection for opening the door. If a method has a long sample
prep phase, however, a longer cycle time may be required.
