8.7 Alarm parameters
Alarm and activation parameters
AL (AH) allows you to determine the activation temperature for low (high)
temperature alarm LO (HI). The set value AL (AH) is always compared with
the value detected by the control probe. The parameter Ad represents
the alarm activation delay in minutes; the low temperature alarm (LO)
activates only if the temperature is lower than threshold AL for period
of time greater than Ad. The thresholds can be relative or absolute,
depending on the value of parameter A1. In the fi rst case (A1=0) the
value AL indicates the deviation regarding the set point and the low
temperature alarm activation point is: set point - AL. If the set point
diff ers, the activation point will automatically diff er. In the second case
(A1=1), the value AL indicates the low temperature alarm threshold. An
active low temperature alarm is indicated via internal buzzer, with the
code LO on display and with the activation of the alarm relay. The same
occurs for high temperature alarm (HI), considering AH instead of AL.

Notes:
• The alarm LO and HI are alarms with automatic reset. A0 determines
the hysteresis between the value of the activation and deactivation
of the alarm;
• if you press the Alarm button when the measurement is above a
threshold, the buzzer and the alarm relay immediately turn off , and
an indication of the alarm code will remain active until the measure
falls within the activation threshold. Parameter A6 has similar meaning
as parameter c4 (duty setting). If an external alarm occurs, the
compressor works for a time equal to the value set for parameter A6,
while it remains OFF for a fi xed period of 15 minutes.
• In case of relative alarms (A1= 0) both AL and AH are considered as
absolute values (e.g. AL= -10 is considered as AL= 10)
8.8 HACCP Alarm parameters and
monitoring activation
In order to activate HACCP alarm monitoring, set parameter HCE=1.
HA alarms
The HA alarm is generated if during normal operation it is noted that the
temperature read by the control probe exceeds the high temperature
threshold for the time Ad + Htd. Therefore compared to the normal high
temperature alarm already signalled by the control, HACCP alarm type HA
is delayed by a further Htd time specifi c for HACCP recording.
