7.1.2 Instrument procedure in case of power failure
The specimens are then safeguarded by lling the retort with a safe reagent.
The objective in case of power failure is to secure the tissue samples in a currently running program
so that they can continue to be processed without hesitation after the power supply is restored. The
main emphasis is on the safety of the tissue samples, not the speed of processing.
In the event of a power failure, an alarm is not sounded immediately because the instrument is
supported by an uninterruptible power supply (UPS). This means that if the power supply fails, the
battery will begin supplying power to the instrument.
This is indicated by the green LED (107) in the unlocking button (44) illuminated under the retort
(Fig. 244)
The specimen protection system is initiated. Once the specimens have been secured, a restart is
performed. If power has been restored by that time, the instrument is restarted normally and
processing resumes. An alarm is not sounded.
If the instrument remains without power for a prolonged period, and it is not restarted, an alarm
is triggered!

If the instrument detects a power failure, the heaters and the monitor are im-
mediatelyswitched o. Ifthe powerfailure lastslonger than 10s,the safety
mechanism is initiated.
The property of a safe reagent is that the specimen can stay in it for a long time
without being damaged.
A safe reagent is assigned to each program step/reagent group.
