When the HF alarm is detected the following information, regarding the status parameters, is recorded:
temperature before the power failure;
duration of the power failure ;
time the power failure is detected (instant the power resumes );
temperature reached on resumption of power;
number of events (HF) detected.
In the case of a series of alarm (HF) events, the information on the alarm is updated:
both temperatures involve the highest value of all the events recorded;
the time refers to the last event;
the duration is the longest of all the events recorded;
the number of events is increased by 1.
Alarm signals: the detection of one of the two alarm events, HA or HF, is signalled using the LED display of the plug-in
instrument, and by activating any alarm devices available on the instrument: alarm LED, buzzer if featured, alarm relay if featured.
HA alarm: the display LED
shows the HI alarm code flashing
alternately with the temperature value, the alarm LED
is on and
the upper segment
of the left-most digit is on.
If present the buzzer and the alarm relay are also activated.
HF alarm: the display LED
shows the HI alarm code flashing
alternately with the temperature value, the alarm LED
is on and
the lower segment
of the left-most digit is on.
If present the buzzer and the alarm relay are also activated.
8.3.9 Cancelling the alarms
In the event of the HA or HF alarm signal, the signals can be reset,
both the signals and the recording of the status can be cancelled
completely:
press the
button for 2 seconds to turn off LED , silence the buzzer and deactivate the alarm relay, if present. The display
still shows the HA or HF alarm status (segments and in the figure) and the alarm code;
use the parameter to to completely cancel the pending alarms, signals and status recording variables.
Warning: resetting the signals or the entire status of alarm cancels the signals requested by the HACCP module; if other alarms
detected by the plug-in instrument are present, some signals may remain active.
