- Automatic Error Reset
Simplified mode (for technical unskilled
personnel) for error reset that, when
implemented, tries to remove any non-critical
error condition in the VM operation.
Starting the Error Reset Procedure
The error-reset procedure is started by pressing
both the P1 ‘Programming’ and P2 ‘Maintenance’
simultaneously for at least 5 seconds - see fig.
40, ref. 1 and ref. 2.
A beep signals the procedure start.
Reset Procedure in Absence of Errors
If no failure is present, the display shows the
message ‘Ok - 0/0’. The user can go back to the
standard mode by pressing ENTER.
In this way, a quick system check-up by the
operator is also assured.
Reset Procedure in Presence of Errors
In presence of errors the procedure consists of
two phases:
1. Error list;
2. Error removal (attempt to remove).
1- Error list
The VM displays a list of errors detected. The
first line of the display indicates the total number
of errors ‘ERRORS XX’.
The second one displays their descriptions on
one or more screens. This list shows current
error or trouble messages: Each message is
displayed on a single screen page containing
their descriptions, for example: ‘NO WATER 01’.
The user can pass to the following screen page
by pressing ENTER.
By pressing ENTER again after viewing the last
screen, the user will remove the errors.
2 - Error removal (attempt to remove).
The VM tries, in sequential order, to remove the
errors automatically. During this phase the error
subject to the reset procedure is displayed;
In the second line of the display there is a ‘status
bar’: the bar elements are made by points (“.”).
At the end of each attempt the display shows
the message Ok/Fail and then proceeds with the
following step.
If, at the end of the sequence, all the errors have
been removed, the reset has been carried out
successfully; otherwise - if one or more errors
could not be removed - it failed.
Successful Reset
The VM shows the message ‘ Ok - N/N’ with a
long single beep.
N indicates the number of errors removed.
The vending machine is reset by pressing the
ENTER key.
Reset failed
If, at the end of this procedure, at least one error
condition remains unchanged, the display will
show the message ‘Fail X/N’ where X is the
number of errors that could not be removed and
N the total number of errors detected.
The message is accompanied by some short
beeps.
The vending machine is reset by pressing the
ENTER key.
- Error Log
The VM stores in its internal storage significant
incidents occurring in the VMC (for example
errors, trouble signals etc.)
The storage takes place at the detection of the
error condition and consists in storing the
following information:
1. error or failure code
2. location of the signal source
3. day, month, hour and minute of the error
detection - this information is given only if the
VM is equipped with a timekeeper.
The information is included in a list that can
contain up to 50 elements, over that limit the
information is stored starting by position 1
(previous information will be lost).
