Power on-
Restart
On: If the power is lost during a run, when the power comes back on, the au-
tosampl
er will restart the injection that it was carrying out at the moment of the
power failure
Off: If the power is lost during a run, when the power comes back on, the au-
tosampler will return to the home screen (see paragraph 7.1), without completing
the run
• Injection mode: sets the predefined injection mode. This parameter is editable only if the
system is configured for two injectors. This setting is always used for single injection runs, while
during an automatic run it is only used if the injection mode in the injection sequence is set to
“Default” (otherwise it will take the mode specified in the injection sequence). See paragraph
5.3.2 “Setting sequence step parameters”:
Injection
Mode
Front: the autosampler injects only in the first injector
Rear: the autosampler injects only in the second injector
Confirmation
: the autosampler injects the same sample in both injectors
(see “Confirmation mode” explanation in paragraph 11 “Appendix A – Glos-
sary”).
• Injection Synchro: sets the synchronization mode between the autosampler and the analyzer
or other instruments during the execution of one or more injections.
