7 “HACCP” FUNCTION
7.1 Foreword
Using the “HACCP” function, it is possible to memorise up to 9 events for each of the 3 HACCP alarms, after which the
most recent event overwrites the oldest.
The following table illustrates the information relative to the HACCP alarms, which the device can memorise.
Alarm Code Critical value
Date and time of
occurrence
Duration
temperature-controlled
blast chilling or deep
freezing not concluded
within maximum
duration alarm
tiME
the maximum
temperature detected by
the needle probe after
temperature-controlled
blast chilling of deep
freezing not concluded
within maximum
duration
yes
from 1 min to 99 h and
59 min, partial if the
alarm is in progress
maximum temperature
during storage alarm
AH
maximum cabinet
temperature during the
alarm
yes
from 1 min to 99 h and
59 min, partial if the
alarm is in progress
power-cut during storage
alarm
PF
the cabinet temperature
at restore f power supply
yes
from 1 min to 99 h and
59 min
To prevent repeated memorisation of power cut alarms (“PF” code), make sure that the device is in the "stand-by" or
"on" status before disconnecting the power supply.
If the duration of the power cut alarm (“PF” code) is such to cause a clock error (“rtc” code), the device does not
memorise the date or time the alarm occurred or its duration.
The HACCP LED supplies information relative to the memory status of the HACCP alarms of the device; see paragraph
10.1 “Signals”.
