HACCP FUNCTION
5.1
Preliminary notes
The instrument is able to store up to 9 HACCP alarms, after which the
most recent alarm will substitute the oldest.
The instrument provides the following information:
• critical value
• the date and time the alarm was signaled
• the duration of the alarm (from 1 min to 99 hours and 59 min, partial
if the alarm is in progress).
CODE ALARM TYPE (CRITICAL VALUE)
AL
minimum temperature alarm (the minimum temperature
of the cell during the alarm)
AH
maximum temperature alarm (the maximum temperature
of the cell during the alarm)
id
door microswitch input alarm (the maximum tempera-
ture of the cell during the alarm); see also parameter i4
PF
power supply interruption alarm (cell temperature when
power is restored); see also parameters A10 and A12
Notes:
•
to avoid repeatedly storing alarms due to interruptions
in the power supply, disconnect the power when the
instrument is switched off
•
if the duration of the power supply interruption alarm is
long enough to cause a clock error (code “rtc”), the instru-
ment will not provide any information about the alarm
duration
•
if the instrument is switched off no alarms will be stored
When the problem that caused the alarm disappears, the display is
restored to normal operation, with the exception of the power supply
