7. Troubleshooting
First, the current status of processing the program that is running is determined.
This includes:
• Determining the step number.
• Reagent of the step (reagent in the retort).
• Safe reagent for this step.
• Status of the step (filling, processing, draining).
• Whether the safe reagent has already been used in the program.
• Reagent of the next step.
• The system checks whether the last safe reagent used in the program is possible as a safe state
(compatibility).
• This safe reagent is then filled into the retort and the program step counter is corrected. In
doing so, a search is carried out from the current program step going backwards until a safe
reagent program step.
(It is also possible to proceed to the next step if the current step was completed and a safe
reagent is present in the next program step.)
After the actions described, the ASP6025 (and thus the specimens as well) is in a safe state.
The tissue samples are in a safe reagent and the currently running program is modified such that
when the power supply is restored, the processing can be resumed.
The software now carries out a controlled shutdown of the system.
The instrument remains in this state until the power supply is restored. It then restarts automatically.
The end time of the protocol is recalculated, the power failure entered into the Run Logs and the
operator is notified of these using a display.
