Solution Of Problems - LAVAZZA Magystra LB 2600 INT Installation And Maintenance Manual

EN
Any event that may occur during the operation of
a machine may totally or partially compromise its
functionality.
To help the operator restore the normal functionality
of the vending machine, the display shows an error
code as an abbreviation that identifies the malfunc-
tion and helps the operator find the faulty device.
In the machine, the error may be signalled with or
without a suffix that – if present – is intended to
specify the meaning better. The number on the dis-
play identifies for sure the devices, assemblies and
functions in question.
Not all malfunctions are signalled by an error
message since the latter is generated by electric
controls that are not made available in all ma-
chine districts .

SOLUTION OF PROBLEMS

CPU integrated circuits not working properly
Water level low in the inner tank, or no water.
The volumetric counter is blocked or can not detect pulses in water flow to the thermoblock; display will
shows: "add water and turn off and on".
The capsule unit motor is not detected or the motor is short-circuited or disconnected.
The capsule unit fails to move within the pre-set period of time.
The capsule unit fails to go up within the pre-set period of time.
Stored data are not consistent (reading or writing error) and the overall operation of the vending machine
may be otherwise than expected.
The PROG internal programming button is short-circuited or it has been held down too long.
A button appears as if it were constantly pressed.
The actual 24 V dc voltage value is higher than the tolerated one.
The measured 24 V dc voltage value is below the admitted threshold or totally absent, e.g. because a
fuse has tripped; find out and remove the causes that have produced this error before powering on the
machine again.
The thermoblock water temperature is higher than the programmed value.
Water fails to achieve the set temperature.
Sensor shorted or open.
In the following table:
• The first column shows the machine number. Any
variant is shown with the detail letters for more
specification.
• The second shows the machine district or func-
tion affected by the event.
• The third one contains a comment, the purpose
of which is to help find a solution; these notes
are surely not exhaustive because a malfunction
may have several causes or be originated by an
ensemble of factors, but they any way give some
hints on how to proceed.
