ALARMS
J.1
Introduction
The electronic board manages two types of alarm systems:
•
HACCP
for monitoring and storing high temperature alarms.
An HACCP alarm status is signalled by sounding of the
buzzer, blinking of the HACCP red LED, and the alarm
message appearing on the display.
•
SERVICE ALARMS
for storing and managing all the alarms
available on the electronic board (except the high temper-
ature and blast chilling cycle end error alarms).
J.2
HACCP alarms
For managing the compartment high temperature alarm and
the blast chilling cycle end error alarm.
If no alarm is active: the “TEMPERATURE“ display shows the
message
none
, whereas the “TIME“ display remains off.
In case of an alarm the “TEMPERATURE“ display shows the
alarm number
AL 1, AL 2
, etc., and the “TIME“ display shows
the description of the alarm (see paragraph J.2.1
).
To access the menu, press the button
. To exit the menu
press the button again. Use the buttons
and
to scroll;
the messages
AL 1, AL 2
, etc. will appear. After displaying the
last alarm, the display shows the message “——“; the unit
automatically returns to the main menu after 12 seconds of
inactivity.
To cancel the alarms, press
+
together for 5 seconds.
CAUTION
The reset function is disabled if the
operator has not seen the stored alarms
and the message “RES“ appears on the
TEMPERATURE display.

indicates the start of the alarm,
End Date Time
indicates the end of the alarm (“Date”
format: DD-MM-YY, “Time” format HH.MM; ).
•
Blast chilling cycle end error alarm
This type of control is done to check that a blast chilling/
freezing cycle with core probe ends correctly. If it does not
end correctly, a “
Blast chilling duration outside limit
“
alarm is generated and the display shows:
– the message
Batch
(number)
Ot
(blast chilling time)
MIN
Start
Date Time
End
Date Time
EXAMPLE:
BATCH1 Ot 120MIN Start 25-10-01 15.48
End 25-10-01 17.48.
where:
(number)
indicates the current day’s batch number;
Start Date Time
indicates cycle start;
End Date Time
cycle end.
Batch number
:
Every blast chilling cycle (SOFT/HARD chilling, freezing)
carried out will be identified by a progressive number (1,2,
… ) called the “BATCH NUMBER“. It refers to the current
day and will be reset to
0
at the start of a new calendar day.
NOTE!
N.B. In case of timed blast chilling/freezing,
there are no cycle-end control alarms.
