HACCP ALARM MANAGEMENT
With ambient probe temperature ≤ A1 , after the Ald time, the EL
low temperature alarm is activated.
With ambient probe temperature ≥ A2 , after the Ald time, the EH
high temperature alarm is activated.
During a high or low temperature alarm, the display alternates the
visualisation of the temperature with the EH or EL headings; the
alarm relay is activated (if set), the Buzzer (silenceable) and the
alarm bell icon (flashing).
When the set alarm conditions are turned off, alarm signals
automatically undo (the alarm relay is deactivated, the buzzer is
silenced and the normal visualisation is reactivated).
The alarm bell icon remains on (fix) to indicate that EH or EL alarm
was triggered and the memorisation of the event (see HACCP
menu for displaying the latest temperature alarm activated).
To get the alarm, push the arrow button up when the fix bell light
is on.
Besides, the starting date of the latest EH or EL event is registred,
together with its duration and its maximum or minimum reached
temperature.
A counter of the nr of occurred alarms from the latest alarm reset
(max 99 alarms can be counted) is also present.
To display data related to the latest temperature alarm, enter in
the HACCP menu (push the arrow button up + stand-by for 3
seconds).
Inside the menu, all the data can be scrolled with the up and down
arrows or they can be reset, by pressing the SET button + arrow up
button for 5 seconds.
Once the reset occurred, a BIP with the buzzer is provided to
confirm the occurred cancelation.
To exit the menu, wait 10 seconds without pressing anything or
press simultaneously the up and down arrows.
HACCP variables are available in read-only mode and are the
following:

DIAGNOSTICS
In the case of faults, the "Expert nano" control unit informs the
operator by means of alarm codes shown on the display and an
acoustic signal emitted by the buzzer (if present). The acoustic
alarm can be stopped by pressing the UP key (the error code
remains) and can be reactivated by pressing the SET key. In the
event of an alarm, one of the following messages is displayed:
ALARM CODE TABLE
MEANING
Var
E0 Functional fault of ambient probe.
E1 Functional fault of defrosting probe (in this case, any defrosting
processes will have a duration equal to time d3).
E2 EEPROM memory error. All outputs are deactivated except for
alarm outputs if present.
E8 Man-in-room alarm.
Compressor protection alarm (e.g. thermal protection or max.
Ec
pressure switch). All outputs are deactivated except for the
alarm output if present.
Door open alarm. When the door switch opens and the tdo
Ed
time has elapsed, normal function of the control is reset,
triggering the door open alarm (Ed).
EL Minimum temperature alarm. The letters EL flash alternating
with the temperature (see parameter A1).
EH Maximum temperature alarm. The letters EH flash alternating
with the temperature (see parameter A2).
E9 Room light alarm. The letters E9 flash alternating with the
temperature (see parameter dO2 and Tdo).

ELECTRICAL PRESCRIPTIONS
Avoid using multipolar cables with conductors connected to
inductive and power loads and signal conductors such as probes and
digital inputs. Avoid installing in the same channels power cables and
signal cables (probes, digital inputs or RS485 connections). Reduce to
a minimum the length of the connecting cables, avoiding that the
cabling takes on a spiral form which may have inductive effects on
the electronic system. All conductors used in the cabling must be
appropriately sized in order to support the load which they must
provide. If it is necessary to extend the probes, use conductors with
appropriate cross-sections and not less than 1 mm². The extension or
reduction of the probes may alter the calibration which was
performed in the factory. Therefore, verify and calibrate by means of
an external thermometer.
