10.3 "POWER FAILURE" and "WRONG STATION" messages
"POWER FAILURE" is displayed when power is
restored after a power failure, but only if the
processing cycle in progress has been impaired
by the power failure.
The display reading is accompanied by a sound
signal which intends to attract the user's at-
tention to the malfunction so he/she can take
appropriate measures to rescue the specimens.
The upper line of the display shows the surplus
time the basket remained immersed, and the sta-
tion number where it was immersed due to the
power failure. In the example shown here the
infiltration time in station no. 3 was exceeded by
47 minutes.
If, due to the power failure, the basket is lowered
into a station which is not part of the program
(programmed infiltration time "0 h 00 min"), in-
stead of "POWER FAILURE" the message WRONG
STATION" is displayed. In addition, when the
power is restored, an uninterrupted sound signal
is emitted.
The upper line of the display shows how long the
basket remained in the wrong station due to the
power failure. In the example shown here, the
basket was in station 4 for 16 minutes.
By pressing any key the display reading will
switch back to normal and the sound signal will
be turned off.
Once the power is restored, processing will be
resumed as programmed. The basket will be
moved from the wrong station to the next station
that is part of the current program.
In case of a power failure the carousel
is lowered immediately into the station
where the tissue basket happens to be
located when the power failure occurs.
Once the power is restored, processing
will be resumed as programmed. Possi-
ble impairment of the processing cycle
through the interruption is displayed.
