Power failure scenario and instrument failure
Warning
In the event of a software crash or an instrument malfunction, a previously defined audible
warning signal will sound. In this case, the user has to remove all racks from both instruments,
HistoCore SPECTRA CV and HistoCore SPECTRA ST, as well as restart the instruments afterwards.
Note
• In the event of a prolonged power failure (> 3 sec.), the internal battery ensures that the
HistoCore SPECTRA CV is shut down in a controlled manner and any negative impact on the
specimens is avoided.
• The fully charged internal battery can bridge two successive power failures (> 3 sec.). After
two successive power failures and once the power supply has been re-established, the internal
battery is recharged when the instrument is started up. The user is notified of the charging
process by a note on the screen. The instrument is not ready for use again until after charging.
• After the power supply has been restored, the instrument automatic performs a restart. The user
is notified of the power failure by an information message (→ Fig. 108) on the screen, and the
event is entered into the event log.
• An external UPS (uninterruptible power supply) ensures a long-term bypass, depending on the
specifications of the connected UPS (→ P. 27 – 4.2.2 Using an external uninterruptible power
supply (UPS)).
In case of a power failure, the instrument carries out the following steps regardless of whether just one
or both coverslip lines are in use:
1. The software shuts the screen down.
2. The slides currently being processed in the coverslip lines L1 and L2 are still completely
covered and pushed back into the rack.
3. The rack in the coverslip line L2 is transported by the gripper arm into the unload drawer. After
this, the gripper arm moves into the secure position behind the oven.
4. The rack remains in the elevator in the coverslip line L1.
5. The instrument is then shut down by the software in a controlled manner
(→ P. 31 – 4.5 Switching on and shutting down the instrument).
LL After power supply has been restored, the instrument restarts automatically. An audible warning
signal sounds and a warning message is displayed on the display (→ Fig. 108).

6. Confirm this message with OK, whereupon the instrument shuts down in a controlled manner.
Then follow the instructions in the information message (→ Fig. 108) and remove the slides from the
instrument.
Note
• After the restart of the instrument, the oven is shut down, and the user must reactivate it in
the Oven Settings menu (→ P. 56 – 5.8.5 Oven settings). The user is notified by a information
message upon the setting of a rack.
• For a safe and easy removal of the racks from the instrument, the instrument must be shut down.
Following shutting down, the user can, for example, easily move the transport arm in order to
carry out the necessary steps for removing the racks.
• Check the removed racks for un-coverslipped slides and coverslip those slides manually. In
doing so, observe the sequence in which the individual slides are processed in the coverslipping
process (→ P. 96 – 6.6 Starting the coverslipping operation) and (→ Fig. 75).
• The following chapters shall be observed for removal of the rack remaining in the instrument.

Warning
• Risk of injury! Always wear personal protective clothing (lab coat, cut-resistant gloves, safety
goggles)!
• We recommend calling in a second person for support.
• The instrument software provides instructions on the screen. Compliance with these is mandatory.
• If a manual removal of a rack from the right-side L2 coverslip line is necessary, the transport of
racks in and out of the oven is interrupted for safety reasons. racks may remain in the oven for
longer than 5 minutes as a result.
Note
In the event of instrument malfunctions requiring the user to remove a rack from inside the instrument
manually, note that the instrument software cannot precisely locate a rack inside the instrument and
therefore only gives general instructions regarding manual removal. If the user can readily identify
the rack to be removed upon looking inside the instrument, the user can carefully remove it without
following the instruction on screen if there is no risk of damage to the specimens or the instrument
from doing so.
Manual removal of a rack from the interior of the instrument:
1. Open the load drawer.
2. Open the unload drawer and remove all racks contained (→ Fig. 109‑1).
3. Pull the red retaining lever upwards (→ Fig. 109‑2). Pull out the drawer entirely and lower it
into the rescue position (→ Fig. 109‑3).
4. Locate rack by looking through the shaft of the unload drawer. (→ Fig. 109‑4).
5. Insert your hand into the shaft and try carefully to feel around for the rack.

Warning
• There can still be un-coverslipped slides in the racks. Proceed with utmost caution and care.
• If the elevator interferes with the removal of a rack, then the user must manually lift the elevator
upward (→ P. 146 – 8.3.2 Removing a rack from the elevator of the coverslip line).
6. Lift the gripper with the rack to the very top if necessary and push/pull the gripper arm to the
center of the instrument (→ Fig. 109‑5).
7. Carefully lower the gripper with rack downwards (→ Fig. 109‑6).
8. The rack is now in a position (→ Fig. 109‑7) that facilitates secure removal.
9. With one hand, secure the gripper so it does not fall down and grasp the front part of the rack
with the other hand.
10. Lightly lift the front of the rack to release it from the gripper (→ Fig. 109‑8).
11. Finally, hold the rack upwards in a tilted fashion (→ Fig. 109‑9) and pull it forwards out of the
gripper (→ Fig. 109‑10).
12. Place the gripper in the secure position behind the oven.
13. Close the unload drawer and acknowledge the information message that follows with Ok.
14. Afterwards, the instrument is re-initialized.
15. A Quick Prime (→ P. 125 – 7.3.1 Quick Prime) must always be performed after initializing.
