7 “HACCP” FUNCTION (EVXV812 AND EVXV815
MODELS ONLY)
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

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”.
