English 8.3.2 Description of maintenance menu messages 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
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 (noncritical) error conditions that may occur in the V.M. Operational defects

Recommended solutions In maintenance mode it is possible to: - move the gear motor of the brew group by pressing beverage key 2; - have the mixer rinsed by pressing beverage key 3; - display for 5 seconds total and partial counters by pressing the beverage key 4. - move the cup release / cup bracket gear motor by pressing beverage key 6; - reset errors by pressing beverage key 8
- Error / Message nn It describes the current error - check the cause in section 12 Error messages. If there are no errors present, this message is not displayed. After checking the cause of the error, press the ENTER key to reset the vending machine - for the complete list of errors see section 12.
English - 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).

- the message on the second line indicates that if the program is updated you will pass from the current version (X.yz) to the update flash version (A.bc); - to upgrade the software press the internal key P1 (near the corner) of the CPU card, any other key will have no effect. - The software requires about 30 seconds to be updated and the procedure end is signalled by a message on the display; - turn off the vending machine;

UPDATE COMPLETED

- disassemble the external memory; - assemble the TIMEKEEPER (if present).

English Out of service/Failure conditions In particular situations, the VM can be fully or partially out of service. There are 3 categories (classified by severity): A. failures due to scheduled maintenance conditions which partially block the VM. By these failures (out of coffee, too many dump in the box, out of cups in case of cup preselection) the VM is not out of service but its dispensing function is somehow limited ; B. failures due to scheduled maintenance conditions which block the VM fully. By these failures (out of cups, no water, too many dumps in the box, too high water level in the residues tray) the VM product dispensing is disabled, thus inhibiting the payment systems; C. out of service conditions which disable the entire VM. The VM is brought to this condition when it detects failures which are not solvable with scheduled maintenance. In this condition, the payment systems are inhibited and no VM load can be operated. The following table resumes all failure and/or error conditions which may occur on the VM, listing for any of them: possible cause description category; associated code (i.e. the code shown in maintenance and registered in the error log); effect on the VM state; how to restore the VM normal operation - once the failure/error cause has been removed
