1.1 - IMPORTANT SAFETY GUIDELINES

Before connecting the equipment to the supply voltage, read the following Safety
Guidelines, in order to protect yourself and the equipment from any serious
danger.

• Read all the instructions for the installation, before connecting the supply
voltage and alarm cable.

• Follow all the instructions and precautions concerning the equipment.

Immediately disconnect the supply voltage and alarm cable in the following cases:

• If the connecting cables or the connectors are worn out or damaged.

• If liquid is present, even in the form of moisture, inside the equipment.

• If the case of the equipment shows damage or breaks.

• If it is felt that the equipment requires maintenance or repair.

t Warning: before cleaning the mixer wagon with high pressure jets of water,

disconnect the connection cables, remove the equipment from the mixer
wagon and protect the connectors of the connection cables from water
infiltration. Also take great care to see that the load cells, junction box, alarm
device and other options are not exposed to direct jets of water. y

t Warning: before carrying out welding operations on the mixer wagon, always

disconnect the connection cables. In order to prevent the welding current
from passing through the load cells, it is necessary to short circuit the body of
the load cells with a cable having a suitable cross section, besides positioning
the pliers of mass as close as possible to the welding point. y

1.2 - MECHANICAL INSTALLATION

No special precautions are necessary for the mechanical installation.
The equipment must be installed on a perfectly flat surface, stable and devoid of
vibrations, using the special "Dovetail" fixing system (Figure 2).
The case has an IP65 degree of protection (totally protected against dust and jets
of water).

t Warning: do not install the equipment near heat sources or in the vicinity of

intense magnetic fields (motors, magnets, etc.). y

USERS’S GUIDE

1.3 - CONNECTIONS

The equipment is connected by two connectors of the series MS/MIL - C5015
(see Figure 3). The 5 pole connector, identified by a blue label with the word
SENSOR written on it, is meant for connecting the sensors extension cable,
identified by a blue colored band. The 3 pole connector identified by a red label
with the word POWER/ALARM written on it, is meant for connecting the supply
voltage and alarm cable, identified by a red colored band.
Other connectors can be installed when the equipment is preset for the connection
with options.

t Warning: before making the connections, make sure that the equipment and

the option devices (option) are switched off. y

t Warning: do not force the insertion between the connector of the cable and

that of the equipment, because, if the two do not connect easily, they are
probably incompatible. Before inserting each connector, it is necessary to
verify the type, the position and the reference notch, as inserting the
connectors incorrectly could cause serious damage to the equipment.
After having inserted the connector, screw down the metal fixing ring.
To disconnect the connector, unscrew the metal fixing ring and take the
connector out by holding it by the tip and not by pulling at the cable. y

1.4 - REPLACEMENT OF THE FUSE

Before starting to replace the fuse, try to find out the possible causes which could
have caused the break (short circuits in the power wires of the equipment,
humidity, breakdown of electronic components inside the equipment, ect.).
Proceed with the replacement of the fuse, using one having the same
characteristics, after having identified the cause of the break.

To replace the fuse, follow the operations described below.

1. Take a 3.15 Ampere, 5x20mm fast fuse.
t Warning: if the equipment is supplied with the Three Power Outputs option,

use a fuse by 6.3 Ampere, 5x20 mm, fast type. y

t Warning: disconnect the supply voltage and alarm cable before opening the

case. y

2. Unscrew the 8 fixing screws and open the case, taking special care with the

internal connections of the equipment.

3. Identify on the printed circuit board, the fuse holder indicated by the symbol

F4 and placed near the connecting wires (see Figure 4).

4. Remove the fuse-holder cap and replace the fuse.

5. Replace the fuse-holder cap, and close the case, paying special attention to

the connecting wires, screw the 8 fixing screws.

1.5 - MAINTENANCE

The weighing systems for mixer wagons do not require special maintenance
operations. However, in order to prevent problems in running or breakdowns, it is
advisable to carry out the following operations periodically:

• Check the perfect running of the power wires outside the equipment; also
check for the presence of oxides or humidity at the connection points.
It must be remembered that, very often in areas where food items are handled,
small rodents may be present, which can attack the cables placed even in
places that are not easily accessible.

• Check that the load cells do not show bruises; presence of any rust on the
body of the load cell does not impair proper running. Instead, check the
perfect adhesion between the silicon sealant and the body and the silicon
sealant and the cover, paying special attention to the presence of any cracks
in the sealant, as it may cause infiltration of moisture.

• Check that none of the accessories of the equipment show the presence of
bruises or signs of burning.

• Check, by loading a known weight on the mixer wagon, the correspondence
of the loaded weight with the displayed weight of the equipment.

• Check the fastening of all the screws present on the parts that constitute the
weighing system.

If the equipment needs cleaning operations, use a damp cloth, soft and without
fluff. Never use sprays, solvents, abrasives, pointed or cutting objects which may
damage the case.

1.6 - GENERAL SAFETY GUIDELINES

This equipment has been tested and resulted conform with the requirements of the
Directive 89/336/EEC on the Electro-magnetic Compatibility, and with the
requirements of the Directive 90/384/EEC on the Non-Automatic Weighing
Instruments.

As regards 89/336/EEC, the equipment results in accordance with the limits
imposed for environments of the light industry and for residential and commercial
environments.

This equipment cannot be used for applications included in art. 1 par. 2 letter (a)
of Decree 90/384/EEC.

The equipment, described in this guide, can present anomalies in the functioning
or causing them to the equipments that surround it or connected with it, if it isn't
installed and used in strict accordance with the instructions described below. In
any case, it's not sure that these anomalies don't happen in a specific installation.
If some trouble should appear, contact Technical Service and Support that can
suggest some stratagems to adopt for eliminating the discovered troubles.

For respecting the Standards, it's also
compulsory to point out, in a clear, easily
readable and indelible way, the Max. Capacity
of the instrument indicated in kilogram or ton,
before the equipment is put on the market. Near
the connectors there is a label for identifying
the products (see Figure 5). It has been
purposely prepared for being completed with
the indication of the true Max. Capacity of the whole weighing
system. The Max. Capacity value to be pointed out is the least one
among the one of the equipment, the one of the load cells and the one of the
mechanical structure of the mixer wagon.

The conformity with the Directives is ensured only if original accessories and
spare parts are used.

Any modification or intervention on the equipment that isn't approved in writing
by Label could annul its conformity to the Guidelines and make its use forbidden.
