This handbook contains information and procedures to assist technicians in machine setup and
repair. For this reason, this handbook is reserved exclusively for QUALIFIED TECHNICIANS. Attached
are electrical scheme and programming table.
When turned on, the machine carries out a functional test of the display and all LEDs light up. The
display shows the software version and the machine returns to the function that was active when it
switched off (see BLACKOUT).

Software version
When the machine is turned on, the display shows the software version. For example:
It means software version is 1.00.
In case of you request assistance, get the best possible support from IceTeam1927, the
technician will always need to specify software version number along with the machine serial
number found on the machine’s info tag.

Functions
STOP
In this function, the machine is stopped and the led light associated (backlight) is on.
From the STOP it is possible to access any of the machine's functions.
To change function, you MUST return to STOP before.
The display shows:
If the machine is left on STOP with level uncovered, after 30'' the following message is
displayed “Why in Stop?”to warn the user that the machine should be placed on
PRODUCTION or STORAGE.
Resetting to zero the hour counter MA –MP
To reset the MP hours counter to zero:
- The MP counter resets to zero automatically after having performed a calibration of the
pump pipe (see CLEANING/LOAD/CALIBRATION PUMP TUBES).
To reset the MA hours counter to zero:
- Press STOP for 20”
- When the event reading message (**READ EVENTS**) is displayed, wait for the
message "Reset hrs Count" to be displayed.
The hours count selected will reset to zero (MA)
Resetting to zero of the total and partial hours counter
By pressing MIX immediately after the return of voltage and keeping it pressed for at least 5"
the total and partial (daily) cones are set to zero.
The display shows:
10:33:21 Fri

SL193-011342 ED00 10-2018 12
The cones are memorized with one resolution of 1 unit.
Event log
The machine has a memory for storing events (event log). To read the event log on the
display the machine must be stopped. Press and hold STOP for 3’’. The display will show the
following sequence:
The last screen corresponds to the last stored event.
To scroll the events, press the INCREASE button (next event) and DECREASE button (previous
event). To exit the event log, press STOP or do not press any button for 30’’.

PRODUCTION
Cylinder
Access to the PRODUCTION is only permitted with the level covered.
In PRODUCTION mode the following outputs are activated MA, MP, EVAria, MV e MC.
For the beater motor, if the current absorption
HOT < Set Hot (U16)–Isteresi Hot (T03),
the cylinder cooling is activated (EVFC switches ON) until HOT value, set in User Menu, is
reached (U16 user).
MP/EVAria will keep active until Set. Current. PP (T29) is reached (See Chap. Pump Pipe
Calibration), or the maximum time permitted, MP ON Time Prd. (T42), if the Set is not reached
within this time.
When the consistency set is reached, EVFC switches OFF and EVRC switches ON for a time
programmed Hot Gas (T05).
When the consistency set is reached MA keeps ON for a time programmed Delay beater
(T07).
In this moment, the cabinet will be cooled if necessary (TEV ³ Storage Temp. (T23). MC and
MV keep ON and MVcab and EVFV will switch ON.
Once the HOT is reached, if no cone is taken, the beater is activated every 10 minutes
(Cyclic Timer) for 5’’, to control the ice cream consistency: if HOT < Set HOT (U16)–Isteresi Hot
(T03) also the compressor and electro valve are activated (EVFC) to bring the consistency to
the HOT set value.
If the consistency is reached and the machine is on hold in PRODUCTION function, if a cone is
taken (MIR activated), MP and MA switches ON 5’’ to control the consistency.
During PRODUCTION, when the level sensor in the hopper is uncovered, it is only available the
dispensing of a limited number of cones Last Cones. It is shown in the display Mix Out, in the
first row and in the second one it is shown the number of cones remaining. In example:
:
Mix Out
Last cones 10

SL193-011342 ED00 10-2018 14
Overrun settings
The overrun adjustments of the ice-cream of the cylinder is carried out through an air electro-
valve connected to the pump. In PRODUCTION, once the MP is activated, the EVAria
activates during the time in which the MP is ON.
This valve activates cyclically with ON/OFF times adjustable in step Overrun 1 (U18 or T41). This
parameter is programmable from 1 to 6, and correspond to each of the set ON/OFF times
(see table below):

It also has value 7, free and adjustable in the Prog menu for the cylinder with the parameters

Do Not Serve (WAIT)
When PRODUCTION is selected, the display shows –“Wait!”which means that the ice-
cream has reached its ideal texture and then, it should not be removed until the message
turns off.
For example:
Once the HOT is reached (the first time, while in the following the value of
HOT > Set Hot (U16)–Hysteresis Hot - HOB Hot Block (T49))
will have a normal operation. On this point, the display shows:
Wait! Serve
TEV +4°CW- 14

SL193-011342 ED00 10-2018 15
NOTE: If the consistency is below the value programmed in the step Set Hot (U16 user)–Hysteresis Hot - HOB
Hot Block (T49) - Wait! is shown on the display. This means the ice-cream is not ready to be removed.
To deactivate the message, adjust to zero the parameter HOB Hot Block (T49).
Ice in the cylinder
In PRODUCTION, if the TEC temperature reaches a value lower or the same as the step Ice
Cylinder, the Ice Cylinder alarm, which is memorized ONLY in the event, is generated.
The display does not view this alarm.
In this condition, all the outputs related to the cylinder are deactivated and the machine
then cools the cabinet, if necessary. When the PRODUCTION timeout finishes, the texture is
examined again if the TEC of the cylinders is greater than Ice Cylinder.
Timeout Prd
In PRODUCTION, if the texture does not reach the set in the time expected according to that
established in the step Timeout Prd., it is necessary to force the end of cycle, as if the HOT had
been reached and the events alarm memorized (with Timeout Prd. Alarm in the display).
If the Hot Block (T09) is not reached then the machine passes in STOP with Timeout Prd. alarm
on the display.
Blocked Beater
In PRODUCTION, if the texture reaches a value greater than 126 in 5’’., all the cylinder outputs
are deactivated and the machine cools the cabinet if necessary, with the alarm Blocked
Beater. This control is necessary to preserve the belt.
Cabinet
The cabinet is kept through the TEV probe. It cools when TEV Storage Temp. (T23). In this
condition, the MC, MV, MVcab and EVFV activate, until reaching the set Temperature.
The cabinet and the cylinder never activate at the same time.
The cylinder has priority: Firstly, the cylinder is taken to texture and then the cabinet in
temperature. While the cabinet is in operation, if the cone is supplied, the cabinet stops and
the cold in the cylinder activates until the product has the texture again.

TEV +4°C W- 14

SL193-011342 ED00 10-2018 16
Inside the cabinet there is a fan (MVcab) to favour the cooling of the air inside the cabinet.
This fan is active in cooling phase and turns off when reaching the set temperature, except in
the cases in which the cabinet door is open or a cabinet defrost cycle is being performed.
TGC (T.RC) control
The TGC (T.RC) probe controls the cabinet evaporation temperature and, through the
control board, it manages the times necessary to cool the cabinet.
The TGC (T.RC) probe adjusts the cooling level through the ON/OFF switch of the EVFCab:
-If TGC < -14°C ➔EVFCab OFF during 130 - 75 tenths of second; the remaining 75
tenths of second EVFCab ON
-If TGC < -11℃➔EVFCab OFF during 120 - 75 tenths of second; the remaining 75
tenths of second EVFCab ON
-If TGC < -8℃➔EVFCab OFF during 110 - 75 tenths of second; the remaining 75
tenths of second EVFCab ON
-If TGC < -5℃➔EVFCab OFF during 100 - 75 tenths of second; the remaining 75
tenths of second EVFCab ON
-If TGC < -2℃➔EVFCab OFF during 90 - 75 tenths of second; the remaining 75 tenths
of second EVFCab ON
Temperature controls of the liquid in the condenser (TGV (T.CN)):
In PRODUCTION, the temperature of the liquid coming out of the condenser performs a
double control:
MV speed control: Adapts the operation of the machine (noise/power consumption) to the
atmosphere where it is installed. The machine performs a speed control of the MV according
to the reading of the TGV (T.CN).
Maximum condensation pressure control: According to the temperature read by the TGV
(T.CN) performs a ON/OFF switching of the EVFC, so that too high pressures are prevented at
room temperature above 40ºC.
