6. Troubleshooting
6.1 General
→
For all error states, the instrument takes corrective measures to
protect the specimens, except in such cases where continued
functioning of the instrument would be possible only under hazard-
ous operating conditions.
The Leica ASP200 S is equipped with a cutting-edge fault detection and
troubleshooting system.
When detecting a malfunction, the instrument provides the operator with
detailed error messages and corresponding steps to take via the screen.
• All processes are recorded in detail in the "Run Log."
To inspect the processes, the Run Log file can be opened by pressing
the MENU and RUN LOG symbols.
6.2 Power failure
Power failure during an infiltration program
• If a power failure occurs during an ongoing infiltration program, the
Leica ASP200 S calculates the power failure duration into the total dura-
tion of the step taking place; in other words, the respective step is not
lengthened due to the power failure.
• If the power failure continues for longer than the remaining duration of
the step during which it occurred, the Leica ASP200 S does not shorten
the following steps.
• If, on account of a power failure, the paraffin temperature is reduced to
the point that the paraffin is no longer suitable for continuing the ongo-
ing program, the Leica ASP200 S builds in a delay time sufficient to bring
the paraffin back to a suitable operating temperature before the paraffin
step.
Power failure during a retort or paraffin cleaning program
• If a retort or paraffin cleaning program is running during a power failure,
the total program duration is lengthened by the duration of the power
failure. This is to make sure that the cleaning results are not impaired.
