Technical Information
Once the cycle to change the duration of the SOFT phase
is started (never greater than the parameter C4) simply
press the button (3) which will show on the display (19)
the wording "Soft" and on the display (18) the value in
minutes of the SOFT phase. With the +/- buttons, it is
possible to increase or decrease this value and confirm it
with the button (3) or wait 5 seconds (N.B. THE CHANGED
VALUE ONLY APPLIES TO THE CYCLE IN PROGRESS).
In the case of temperature chilling, the set changes will
be decided by the product temperature detected (see
paramerer cd).
"HARD" -3 LEDs on (Default)
In this condition and in the absence of adjustments 0.10V
of the compressor, there will be a set cell temperature of
-40°F (-40°C). This set accelerates the freezing process in
the presence of products that do not require particular
preperation.
"RUN" -4 LEDs on flashing
In this condition and in the absence of adjustments 0.10V
of the compressor, there will be a set cell temperature of
-40°F (-40°C). This set accelerates the freezing process in
the presence of products that do not require particular
preperation. In this case then the deep-freezing cycle will
be continuous without moving into storage. The move
to storage will be performed by pressing the button (3)
and reducing the LEDs from 4 to 3. That process should
be used in continous insertion and extraction condition
produced by the blast chiller.
During negative chilling, the compressor stops when the
air temperature reaches the planned set point. In this
cycle there will NOT BE automatic defrosting.
- Probes value reading
With the cycle in progress, pressing the button (12) will
chow in sequence, after the cell probe value, the values
of the insert probe 1 and 2 and the evaperator probe in
flashing mode on the display (18) while on the display (19)
will appear the wording in sequence of SP1, SP2 and SE
that represent the type of probe being displayed.
7.5 - Storage phase
Storage always takes over and automatically after every
chilling event (apart from the negative RUN+HARD
exception) and keeps the product at the storage
temperature of 35.6°F (2°C) or -13°F (-25°C), depending on
the typre of chilling.
These values will be editable in all cases by pressing
the button (2) or (3). It is possible to change during the
storage phase the temperature set which appears flashing
on the display (18), while on the display (19) the wording
SET appears. To adjust the value (within 6 seconds) press
the buttons +/-.

8 - DEFROST MODE
"Gas-hot" or "air" defrosting takes place:
- in automatic mode only during the storage phase and
with a default time of 8 hours that is editable - or -
- manually both with machine in storage and with machine
in STOP (not during chilling) by pressing the defrost
button (13). All defrosting in progress can be interupted
by pressing the defrost button.
Duration of the defrost cycle is given by reaching the
defrost end temp measured by the evaporator probe;
there is in any case a maximum length for defrost after
which defrosting ends automatically.
Whenever possible, namely during the cycles of chilling,
of ice-cream hardening, of storage, defrosting in storage
and defrosting at machine standstill, it is possible to view
the evaporator probe temperature by pressing the button
(12): the display will show fo r5 seconds the wording "S.EV
+ valore".
Manual defrosts cannot be activated in the event that
the value of the evaporator probe is higher than a certain
temperature value, in which case a series of beeps will be
emitted to alert the user to the fact that it is not possible
to defrost and the wording "NoDefrost" will appear for 5
seconds.
9 - DRYING WITH MACHINE AT STANDSTILL
When the machine is stopped by pressing the button (13)
for more than 3 seconds, ventilation will be activated for
a maximum time of 20 minutes (either with door open
or closed). During this function the LED flashes and the
display shows the scrolling text "Air Defrost". To exit from
this function press (short press) the defrost button (13).
This mode is used when the machine is at a standstill for
air defrost or to dry the machine after cleaning.
10 - DOOR OPENING
When the machine is running (chilling, storage, defrost),
the door is opened, the display shows the scrolling text
"DOOR OPEN" every 5 seconds, alternating with the value
read, and the beeper emits beeps.
When closing the door, the fan starts without delays.
If the machine is running the door remains open for
more than 5 minutes, the fan does NOT start again. The
compressor is also locked and the open door alarm is
given. Door reclosing, resetting of the audible alarm,
visual and alarm relay.
If the door is opened while the machine is in "stop" the
beeper does not sound but the appearance of the wording
DOOR OPEN continues.
