10.5 HACCP alarms (HACCP = Hazard Analysis and Critical Control Point)
These are specifi c alarms for controlling the operating temperature, recording any anomalies due to power failures or an increase
in the temperature due to other causes (breakages, extreme operating conditions, user errors, etc.); see “HACCP alarm parame-
ters and activating monitoring” for details.
Two types of potentially critical HACCP events are managed:
• type HA alarms, high temperature during operation;
Example: The critical temperature was exceeded, the alarm was not managed and the temperature remained above the
threshold for longer than the maximum tolerable time (thresholds defi ned by site HACCP procedures). The event is critical
and potentially hazardous.
• type HF alarms, high temperature after power failure;
Example: The unit was powered off . When restarted, the temperature is above the threshold and does not return to an acceptable
level within an appropriate time (parameters defi ned by site HACCP procedures). The event is critical and potentially hazardous.
When an alarm occurs, the HACCP icon comes on (if featured), the display shows the alarm code, the alarm is logged and the
alarm relay and buzzer are activated.
10.5.1 HACCP alarm parameters and activating monitoring
Type HA alarms
The type HA alarm is generated if during normal operation the temperature read by the control probe exceeds the high temper-
ature threshold for the time Ad+Htd. Consequently, compared to the normal high temperature alarm already signalled by the
controller, the type HA HACCP alarm is delayed by a further time Htd specifi cally for HACCP recording.

Type HF alarms
The type HF HACCP alarm is generated following a power failure, if when power returns the temperature read by the control
probe exceeds the AH high temperature threshold. HFn indicates the number of type HF alarms activated.

(*) Parameters visible in APPLICA.
The HA and HF alarm signals can be reset using the alarm reset parameter rSA.
The HACCP event log can be deleted using parameter rHP, from the Applica Desktop confi guration software or in the Applica
app (Bluetooth™ connection only).
Notice: deleting the HACCP event log is irreversible.
