Troubleshooting
When a problem occurs with the HistoCore PEARL, take the following steps to diagnose the problem:
1. Read the error message(s).
2. Follow the instructions on the message.
3. Check the Run Log for any messages that indicate the nature of the failure. If the failure
occurred during a program run, check the Run Log for an indication of whether the failure
occurred during the fill, processing or drain cycles, and the station in use at the time.
7.2
Power failures
If there is evidence of a power failure to the instrument:
•
Verify that the power plug is plugged into the socket and that the socket is switched ON.
•
Verify that the power switches on the rear of the instrument (adjacent to the power lead) is switched
ON.
•
Disconnect the instrument from the power supply, take out the main fuses and check them for
continuity. In case of discontinuity, replace them with fuses of the correct value, reinsert them and
reconnect the power cable. For how to replacing the fuse, see
.
Note
If you cannot identify the problem by carrying out the above listed steps, call Leica Biosystems
Technical Service.
Caution
If the instrument detects a power failure, the heaters and the display are immediately switched off.
The objective in case of power failure is to secure the tissue samples in a currently running program.
The main emphasis is on the safety of the tissue samples, not the speed of processing.
In the event of a power failure, local alarm and remote alarm are triggered off.
After the power is restored, a message box is displayed, instructing the user to take out the specimens.
If no operation is taken to the instrument with 5 minutes after the message box appears, the system
starts reheating and the specimens are then safeguarded by filling the retort with a safe reagent.
If the power can not be restored in time, remove the specimens and put them into a corresponding safe
reagent. Check which bottle is running when the power fails. After the power is restored, check if the
paraffin is melted or not, set a program and reprocess the specimens.
Note
The property of a safe reagent is that the specimen can stay in it for a long time without being
damaged. An individual safe reagent is assigned to each program step/reagent group.
