(Translated from Italian)
- The MC BOX Electronic Panel does NOT come with protective switches;
it is therefore mandatory that the MC BOX be installed with an electrical panel
that is suitable to the individual MC BOX and has a differential power switch or,
at the very least, a fast-access device such as a socket/plug, to be used in the
event of anomalies;
- All the electronic components found within the MC BOX container have been
pre-wired and tested at the factory; as such, it is NEVER necessary to have the
MC BOX opened by the person who installed it or the plant operator, unless the
fuse protection on the I/O card needs to be replaced;
- The installer should carry out a plug/socket connection for a quick sectioning of
the electric system in case of failures.

ICOMMISSIONING
To correctly commission the MC BOX the sequence of operations indicated below
must be followed and the MC control system functions must be known (see attached
manual).
Once the power connections have been made, the MC BOX can be energised by
means of the master switch to be fitted by the installer on the upstream line.
Switching on of the MC system will be indicated by the lighting up of the two backlit
LCDs fitted on the front.
NOTE:
In the event of continuous current power supply (DC), a fuse size that is appropriate
to the DC motor's absorption level should be introduced to the motor
power line.
For example:
• If the connected motor is one that absorbs 10A max then a 12A delay fuse should be
inserted.
• If, however, the motor absorbs 50A max, then a 60A delay fuse should be inserted.
• If the fuse is small, it can be fitted along
the cable inside the junction box, in
position (1) (see illustration)
• If, however, the fuse is very big (e.g. 60A)
and cannot physically fit inside the box,
then it can be inserted along the motor’s
power supply cable in position (2) (see
illustration)

Every MC BOX station can be adapted to the specific requirements of the station
manager. To do this the MC control system must be CONFIGURED.
After completing configuration, user PIN CODES can be assigned to the persons
charged with using MC BOX, in accordance with the detailed information in the MC
manual.
I.2 STATION CONFIGURATION
EN (Translated from Italian)
MC configuration is crucial and must be done by skilled personnel.
To perform this operation, the MC manual must be carefully and thoroughly read.
! WARNING

17
In MANUAL mode:
• The MC's LCD may be switched off (only the
backlight is clearly visible) or you may continue
to see the indication that was present at the
time of transition from AUTO to MAN.
• No PIN CODE is required to activate the
pump; the pump starts when the dispenser
nozzle is removed from its lodging and stops
when it is put back (naturally this is in the event
that the "nozzle contact" function is used).
• The amount dispensed is not shown in any
way.
All the MC BOX functions are controlled by the MC control system.
The MC system can nevertheless be disengaged for any startup or maintenance
activities requiring repeated pump starting.
In these case, it is often convenient to simplify pump startup by not having to enter any
code and record any dispensing data.
To do this, a JUMPER has been fitted on the card that permits switching from
AUTOMATIC mode (code request to access dispensing) to MANUAL mode (no code
request).
I.3 DISENGAGING THE “MC” SYSTEM
WITHOUT
JUMPER
JUMPER
IN POSIT.
AUTO
EN(Translated from Italian)
The jumper is only accessible by opening the front panel and is positioned as
shown in the photo.
In this operating mode, MC does not record any data relating to performed
dispensing operations.
Before accessing this jumper, the voltage must be removed.
! WARNING
Before accessing the electrical parts, be sure that you have disconnected all of
the general switches that power the device.
! WARNING

LEVERY DAY USE
Thanks to the MC control system, all the MC BOX models provide access to authorised
users only.
MC acknowledges User authorisation by means of two alternative systems:
• The entering of a 4-figure SECRET CODE (PIN CODE)
• The fitting of an electronic key (OPTIONAL)
18
Before using the MC BOX station, check the METER ACCURACY.
For this purpose, proceed as follows:
• Enter a previously enabled USER PIN code;
• Run the fuel into a calibrated container;
• Compare the quantity of dispensed diesel fuel using a calibrated container.
If accuracy is NOT satisfactory, proceed to CALIBRATE THE METER according to the
instructions in the specific manual.
I.4 METER CALIBRATION
EN (Translated from Italian)
To correctly check accuracy, always keep to the following instructions:
• Use a precision sample container, featuring a graduated scale, with a capacity
of at least 20 litres.
• Before making the check, always make sure you have eliminated all the air from
the system and then run the fuel until a full and regular flow is achieved.
• Dispense continuously at MC BOX maximum flow rate.
• Stop the flow by quickly closing the nozzle.
• Reach the graduated area of the sample container, avoiding prolonged
dispensing at low flow rate, but rather performing short dispensing operations
at maximum flow rate.
• Compare the reading provided by the container, with that provided by MC BOX,
after waiting for all the froth to disappear
! WARNING
Differences of up to 1/10 of a litre affecting the dispensing of 20 litres of fluid fall
within the guaranteed precision of +/- 0,5%.
! WARNING
All the users to whom a PIN CODE is assigned must be adequately instructed and
be at least acquainted with the contents of this chapter.
! WARNING

The pump will start (if previously enabled) just as soon as the control lever is moved
to ON position, while it switches off as soon as the control lever is moved to
OFF position.
No further manual operation is required to start or stop the pump.
In the case of the simplest configuration (no optional data required), the fuel dispensing
procedure is the following:
• Insert PIN CODE
(or apply the electronic key)
If the MC recognises the activated PIN
(or key), a “GOOD MORNING MANAGER /
USER” message is displayed and the
pump enabled.
For details on dispensing options, please
refer to the M0187 manual.
L.1 FUEL DISPENSING
The configuration of the MC system permits requiring the User to enter further optional
data (vehicle licence plate, mileage, quantity to be dispensed).
For details, see the MC control system manual.
In the event that these options are not set, MC will recognise an activated PIN CODE
and, once the nozzle contact (if applicable) has been closed, the pump is enabled,
allowing it to dispense
EN(Translated from Italian)
Such enabling does not result in immediate pump startup.
The pump is in fact controlled by a switch (positioned in the nozzle seat)
operated by the user.
! WARNING
Fuel MUST ONLY be dispensed under the careful control of the User.
