5 PARAMETER RESET
To reset the parameters to the default values it is necessary to switch on the machine, using the main switch located under the unit,
holding down keys C and D simultaneosly, selecting YES value pressing key C and then confirming it, pressing key A.
It is also possible to reset the parameters to the default values starting the machine in Super Service Mode, selecting parameters
PA27, selecting YES value pressing key C and then confirming it, pressing key A.
6 FUNCTIONAL TEST OF THE MACHINE
The following procedure allows to test the complete functionality of the unit:
1
Switch On the machine.
2
If in Standby set the machine in Working Mode.
3
Set all the bowls in Ice Cream Mode: the gear motors must turn regularly. The icon J flashes on the right display. The icons I
flash on all the displays.
4
After 15 seconds, when the time set by parameter PA15 is expired (delay timer of the solenoid valves, factory default 15 sec.)
the solenoid valves open (the sound "click" must be heard one time for each bowl in a short time). The icon J, on all the display,
stop flashing becoming still.
5
After 180 seconds, when the time set by parameter PA14 is expired (delay timer of the compressor, factory default 180 sec) the
compressor and the fan motor start. Now the cooling system of the machine is working and after some ten of seconds the
evaporators must begin to freeze in the front lower part. The icon I, on the right display, stops flashing becoming still.
6
If it is possible to complete this procedure with success it means that the machine works properly.
This test takes approx. 5 minutes and allows to verify the proper working of the gear motors, of the compressor, of the fan motor, of
the solenoid valves and of the electronic boards all together.
The only thing that this procedure can't allow to verify is the efficiency of the cooling system which can be reduced for example due
to a leak of refrigerant gas. In order to execute such a check, a test with product, 90 minutes long, is required.
7 PROTECTION AGAINST EXCESSIVE DENSITY
In the case of excessive product density, in order to avoid damage to the dispenser, both the freezer and the mixer will be stopped
for three minutes and one of the following messages will appear on the display: “AL03”, “AL06” or “AL08”. After three minutes, both
mixing and freezing will be reactivated and the previous density setting will be decreased by one level.
To reset the alarm message and return to the fixed display, hold down the B key for three seconds.
From serial number 1184, with the introduction of firmware versions 025 and 018, the alarm display has been replaced by the symbol
---- shown on the display.
The alarm display is possible in Service Mode or Super Service (see paragraph 3 and 4) or, during normal operation, by simultane-
ously pressing the + and -.
