8.3.2 Description of maintenance
menu messages
MAINTENANCE
IThis function allows to show and reset the errors
that may be present. It is also possible to upkeep
the vending machine.
The error can be reset through the maintenance
menu or using the Automatic Error Reset mode.
Important
The latter, designed to be used by unskilled
technical personnel, can be activated without
entering the programming/maintenance menu
and tries to remove automatically any (non-
critical) error conditions that may occur in the
V.M.
Failures
This mode does not eliminate all error conditions,
but only those caused by operational defects.
Errors are divided into two groups (defect and
failures) according to their criticality and therefore
according to the easiness of removing the
causes that determined them.
Defects include error conditions automatically
recovered when their cause ceases to exist, as
well as those conditions requiring an operators
intervention that, consequently, can be removed
only upon the operators request.
Failures, on the contrary, always require a
technical intervention of skilled personnel.
The following table shows the error conditions
divided into their two categories
