Reset procedure when no errors are present
If no failure is present, the message “Ok - 0/0” is
displayed. The user can go back to the standard mode
by pressing the ENTER key.
This way, a quick system check-up by the operator is
also ensured.
Reset procedure when errors are present
If errors are present the procedure consists of two phases:
1. Error list;
2. Error removal (removal attempt).
1- Error list
The VM displays a list of errors detected. The first line
on the display indicates the total number of errors “XX
ERRORS”.
The second line on display shows the list and descriptions
of errors on one or more screen pages. This list shows
the current active error or fault messages of the vending
machine: Each message is displayed on a screen with
the error description, e.g.: “NO WATER 01”.
The user goes to the following screen page by pressing
the ENTER key.
The error removal stage is accessed by pressing ENTER
again after the last screen page.
2 - Error removal (removal attempt)
The VM attempts to remove the errors automatically in
sequential order. During this phase the error subject to
the reset procedure is displayed.
A “status bar” is shown on the second line of the display:
The bar elements are “dots” (“.”). 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 is considered successful; otherwise
(one or more failures are still present) the reset is
considered failed.
Reset successful
The VM shows the message “ Ok - N/N” and emits 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 a few short beeps. The
vending machine is reset by pressing the ENTER key.
- Error recording
The VM records significant events that occurred to VMC
in the internal Eeprom (e.g. errors, Warning signals
etc.).
Recording takes place when the error condition is detected
and consists of saving the following information:
MAINTENANCE ERROR
MESSAGE nn

ERROR LOG /03

ERROR LOG RESET
Displayed

counter is

Only when a failure occurs,
the message “Reset” is
displayed by pressing Enter.
- Error / Message nn
This describes the current error (check the cause in section
12 - Error messages). If no error is present, this message
is not displayed.
After checking the error cause, press the ENTER key to
reset the vending machine (see section 12 for the
complete list of errors).
- Step down counters
By pressing Enter you may see which operation is needed.
By pressing Enter again it is possible to reset the message
that is bringing the quantity of dispensable water back
to the limit value.
The message does not block the machine. The vending
machine continues working normally even when the
decrement counter is reset.
- Automatic Error Reset
Simplified error reset mode (for use by non-qualified
technical personnel); when enabled, attempts to remove
any non-critical error condition for the VM operation.
Starting the error reset procedure
The error-reset procedure is enabled by pressing both
the P1 “Programming” and P2 “Maintenance” keys
simultaneously for at least 5 seconds (see Fig. 40, ref. 1
and 2).
A beep signals the start of the procedure.
