MACHINE INFORMATION
failurEs
The machine is equipped with several sen-
sors intended to control the various func-
tional units.
As soon as a malfunction is found out, the
type of failure is displayed and the machine
(or part of it) is set out of order.
The failures that are found out are stored in
special counters.
failurE History filE
Use this function to display the failure his-
tory le. The history le shows the failure
name with the corresponding date and
time.
The function shows if the failure is still pre-
sent and/or solved.
From the function you can reset the list of
recorded failures.
cHroNology of EvENts
Use this function to display and lter the
events recorded by the equipment.
An event might be for example the access
to menus, the change of parameters, …
From the function you can reset the list of
recorded events.
failurEs
It displays the faults on the equipment.
If there is no fault, the list is blank
DosEr fault
If the current input of an ingredient motor
falls outside the range of pre-set values, all
the selections using that doser are disa-
bled.
wHippEr fault
If the current input of a whipper motor falls
outside the range of pre-set values, all the
selections using that mixer are disabled.
solENoiD valvE (valvE fault)
If the current input of a solenoid valve falls
outside the range of pre-set values, all the
selections using that solenoid valve are
disabled.
sHort circuit mosfEt
One of the mosfets on the actuation board
remains active.
The mosfets control the activation/deactiva-
tion of direct current motors
sHort circuit
A short-circuit is detected on one of the
direct current motors connected with the
actuation board.
A fault may be simultaneously detected on
one of the direct current motors.
volumEtric couNtEr
The volumetric counter (ow meter) ena-
bles the operator to count the water quan-
tity necessary to prepare a selection.
If the actuation board fails to detect the
volumetric counter pulses produced by the
water passage within a pre-established
time interval, the equipment is put out of
order.
airbrEak watEr loss
The air-break micro (operated by the oat)
signals the lack of water even if no request
has been made for a selection.
The water inlet solenoid valve is opened or
the self-supply pump activated (attempt at
lling the air break).
If the air break is not lled, the equipment is
set out of order.
