5.2. Loading time out management
In case of reagent loading time out, if a processing tank is empty or if the reagent quantity isn’t enough to
cover the appropriate level sensor, the program turns to PAUSE mode and this screen appears:
The LOADING TIME-OUT ALARM is audible for 20 minutes
with an intermittent audio signal. During this period the
reagent loaded (if any) will be kept into the cavity.
DURING THE 20 MINUTES COUNTDOWN
If the operator is in the Laboratory during this phase, he can:
Silent the audio alarm (figure above) and in the meantime check that the reagent level of the processing
tank isn’t below the MIN level and eventually fill the tank with new reagent (see chapter 2.11 for details).
Only maintaining the reagents level between the level markings assures the coverage of all the cassettes.
Clear the audio alarm (figure above) and Abort the processing to unload the rack with specimens from the
unit. Then check that the reagent level of the processing tank is not below the MIN level and eventually fill
the tank with new reagent (see chapter 2.11 for details). Only maintaining the reagents level between the
level markings assures the coverage of all the cassettes.
After this check, the operator can continue the processing with the STEP START function, starting from the
phase not executed (see chapter 3.2.4 for details).
AFTER THE 20 MINUTES
If Reagent Loading Time-Out occurs when nobody is in the Laboratory, after 20 minutes the system starts
the Safety mode procedure and automatically puts the specimens in “safe mode” following this schedule:
•
In case of reagent loading time-out, the unit (after 20 minutes) will enter in SAFETY MODE
procedure, unloading the reagent (if any) and loading the previous reagent of the protocol used. The
previous reagent and its fumes prevent samples from drying.
•
In case of reagent loading time-out of the FIRST reagent of the protocol used, the reagent movement
will be stopped and the rack remains into the cavity. The reagent and its fumes prevent samples
from drying.
This function assures that samples are kept soaked in the reagent until the arrival of the operator and the
software will advise what happened and at which stage the process has been stopped.
The screen will display that Safety Mode Procedure has been
activated, with following details:
-
Date and Time: when the program stopped
- Processing Cycle: Run ID, protocol name and size
- Phase loading step
When the operator is back in the Laboratory, he can Unload
Reagent, Unload cassettes and then CONTINUE the
processing by STEP START (for further details see chapter
3.2.4), according to the indications of the last phase not
executed prior to loading time out.
