HACCP

4.1 Introductory comments
The device is capable of storing up to 9 HACCP alarms, after which the
most recent alarm will overwrite the oldest.
The device can furnish the following information:
• the critical value
• the data and time at which the alarm occurred
• the alarm duration (from 1 minute to 99 hours and 59 minutes,

partial if the alarm is ongoing).

CODE ALARM TYPE (AND CRITICAL VALUE)

minimum temperature alarm (the minimum temperature
of the cabinet or the minimum temperature detected by
the auxiliary probe during the alarm state)

maximum temperature alarm (the maximum temperature
of the cabinet or the maximum temperature detected by
the auxiliary probe during the alarm state)

microport input alarm (the maximum temperature of the
cabinet during the alarm state); see also parameter i4

power failure alarm (the temperature of the cabinet on
restoration of the power supply); see also parameter AA

Warnings:
• the device records minimum temperature alarms and

maximum temperature alarms providing the temperature
associated with the alarm is the cabinet temperature
(parameters A0 and A3 = 0) or the temperature measured
by the auxiliary probe, providing its function is that of
display probe (parameter P4 = 1 and parameters A0 = 2
and A3 = 1)

• in order to avoid repeatedly recording power failure alarms,

disconnect the device power supply while in stand by
mode

• if the duration of a power failure alarm is such as to

cause a clock error, then the device will not provide any
information regarding alarm duration

• no alarms will be recorded if the device is in stand-by

mode.

When the cause of the alarm is resolved, the display returns to normal,
except in the case of a power failure alarm where normal display
function must be restored manually.
To restore the normal display manually:
• press any key.
If parameter u1 is set to 4 (or the service controlled by the fourth output
is the alarm output), then pressing any key will also deactivate the
alarm output.
The HACCP LED provides information relating to the status of the
HACCP alarm memory; please refer to paragraph 6.1.
4.2 Viewing HACCP alarm information
To access the procedure:
• ensure the keyboard is not blocked and that no procedures are

running

• press

for 2 s: the display will show the first available label

• press

to select “LS”

• press

the display will show the most recent alarm code, or one
of the codes reported in the table in paragraph 4.1 fol-
lowed by the number "1" (the higher the number follow-
ing the code, the older the alarm).

To select an alarm:
• press

(to select "AH3" for example).

To display the information relating to the alarm:
• press

the HACCP LED will stop flashing and remain on and the
display will show the following information in succes-
sion (for example):
