14 COMMISSIONING
FOREWORD 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).
ELECTRICAL POWER
SUPPLY
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:
85
86
87

• 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)
STATION
CONFIGURATION
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.
ATTENTION MC configuration is crucial and must be done by skilled personnel. To per-
form this operation, the MC manual must be carefully and thoroughly read.
After completing configuration, user PIN CODES can be assigned to the per-
sons charged with using MC BOX (USER PIN), in accordance with the detailed
information in the MC manual
DISENGAG-
ING THE “MC”
SYSTEM
All the MC BOX functions are controlled by the MC control system. The MC
system can never the less be disengaged for any startup or maintenance ac-
tivities 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 dis-
pensing 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).
ATTENTION 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, ALWAYS INTERRUPT THE POWER SUPPLY
