HACCP FUNCTIONS
The instrument can save up to 3 HACCP alarms (“
HACCP BASIC
”
version) or 9 allarms (“
HACCP EXTENDED
” version).
The instrument provides the following information:
• the critical value
• the date and time when the alarm was triggered (only “
HACCP
EXTENDED
” version)
• • the alarm duration (from 1 min to 99 hr and 59 min, partial if the alarm is
still active).
CODE TYPE OF ALARM
CRITICAL VALUE
AL
minimum temperature

the minimum chamber temperature
during this type of alarm
AH

alarm
the maximum chamber temperature
during this type of alarm
Id
micro port input alarm
the maximum chamber temperature

PF
power failure alarm
the chamber temperature when the
power is restored (parameter AA)
“
HACCP BASIC
” VERSION: The device updates the information
if the new alarm is worse than the one stored or provided that the
information have already been shown. If the device is switched
off, no alarm will be stored.
“
HACCP EXTENDED
” VERSION: the most recent alarm will
overwrite the oldest. If the duration of the “
PF
” alarm causes a
clock error, the instrument will not provide any information
regarding the alarm duration.
When the cause that triggered the alarm is resolved, the display
restores normal operation, except for the power failure alarm,
which requires the normal display to be restored manually.
The HACCP LED provides information regarding the memory
status of the HACCP alarms: if it is on, not all the information
regarding the HACCP alarms have been displayed, if it flashes,
the instrument has saved at least one new HACCP alarm.
