TECHNICAL DATA
GENERAL INFORMATION
PEGO S.r.l. does not accept responsibility for any loss of data or
information, costs of goods or substitute services, damages to
objects, persons or animals, lost sales or profits, interruption of
activities, any direct, indirect, accidental, property, insured, punitive,
special or consequential damage caused in any way, be it contractual,
extra-contractual or due to negligence or other responsibility
resulting from the use of the product or its installation. The guarantee
automatically becomes invalid in the case of poor functioning due to
tampering, impact or inadequate installation. It is mandatory to
observe all instructions in this manual and the operating conditions of
the device. PEGO S.r.l. does not accept responsibility for any
inaccuracies which may be present in this manual in the case that
these are due to printing or transcription errors and reserves the right
to make modifications to its products which it deems necessary or
appropriate,
without

characteristics.
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.
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 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
Var
MEANING
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.
Ec
Compressor protection alarm (e.g. thermal protection or max.
pressure switch). All outputs are deactivated except for the
alarm output if present.
Ed
Door open alarm. When the door switch opens and the tdo
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).
