8.2 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. 26 – 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 racks from both coverslip lines are transported by the gripper arm into the unload drawer.
After this, the gripper arm moves into the secure position behind the oven.
