maiNtENaNcE
The maintenance operations described in this chapter
should be carried out with the machine energised and
therefore by qualified personnel, who are trained in the
correct use of the machine and are aware of the specific
risks of such condition.
To energize the system with the open door, simply insert
the special key into the switch on the payment system
compartment door (see fig. 26).
inside the machine, the only parts that stay ener-
gised are those protected by covers and carrying
a plate with the warning “disconnect the power
before removing the protective cover”.
before removing such covers disconnect the ma-
chine from the power grid.
the integrity of the vending machine and its con-
formity with the rules and regulations in force for
its relevant systems must be checked by qualified
personnel at least once a year.

iNdicatoR lampS
The C.P.U. (Central Processing Unit) board controls all
users set for the maximum configuration of the spiral
compartment and processes the input signals from the
keypad, the payment system and the cooling unit sen -
sors.
The card also houses some LEDs which, during the
machine operation, give the following indications:
- Green LED (3): blinks during normal operation of the
C.P.U. board;
- Yellow LED (4): glows when 5 VDC are detected;
- Red LED (7): glows when, for any reason, the software
is reset.
ConfIGurInG The C.P.u. Board
This board is preset also for the MDB protocol.
The 4 dip-switches for setting the SW2 coin mechanism
(see Fig. 19) should be set to OFF for Executive-BDV
and to on for mdB.
SoftWaRE updatE
The machine is fitted with a Flash EPROM which can be
electronically updated.
By means of a special program and suitable system
(UpKey, Personal Computer or similar) the machine
management software can be updated without replacing
the ePRom.
Warning!
When downloading the software it is advisable to discon -
nect the motor connectors from the C.P.U. board (J1 and
J2).
