12.7 INSTRUMENT PANEL
IVECO manufactures, for its own engines, some types of on-board signal and controls panel.Their con-
nexion to the electrical equipment is done through the engine wiring. Systems for the main deck and
upper deck (fly bridge) have been provided for better control and manoeuvre conditions.
The technical data and instructions for panel installations are available in the technical information man-
uals together with instructions and information to manufacture boards for the dockyard personnel.
The essential panel signals are:
■
Engine coolant high temperature
■
Lubricating oil low pressure
■
Water in fuel
■
EDC system damage / malfunction (if present).
The level of gathered data will depend on the versions and use requirements. It is important the prior
availability of the diagnosis connector fitted in the electrical engine equipment provided by IVECO, in
the presence of EDC system.
In the case of engines equipped with electronic injection system, IVECO provides for an optional
remote control in the engine room to be used during testing and maintenance procedures.
When using it, the main station controls cannot be activated simultaneously, which avoids an unex-
pected engine startup.
Follow carefully the instructions and information details attached to the electrical equipment layout to
operate and use the installation properly.
12.8 WARNINGS AND PRECAUTIONS
Electromagnetic compatibility (EMC)
On board electrical and electronic systems as well as other external ones, may transmit or be sensitive
to parasitic radio signals capable of causing malfunction.
IVECO provides for compatibility tests carried out under specific regulations.
To minimise signal sensitivity in equipment installed by the dockyard personnel, the engine wiring har-
nesses must follow different paths from other wiring on the vessel. The ground connexion installa-
tion should be properly checked to ensure optimal performance at ground connexion points and of
the on board equipment to preserve proper conductivity characteristics through timely periodical
maintenance.
Electrical and electronic devices, such as radio receivers, generators and others, must comply with the
regulations in force regarding electromagnetic compatibility.
To guarantee total compatibility of the manufactured components a test must be carried out after com-
plete assembly.
Welding
When welding near the engine or its systems, disconnect the on board electronic units and place them
considerably far from the engine. Disconnect the alternator and electrical components connectors from
the engine. The electromagnetic field generated by the electrical welding equipment could cause seri-
ous damage.
NOTE
During welding operations, it is not safe enough to disconnect only the storage batteries, since the electro-
magnetic field interferes directly with the component’s electrical lines and generates at the ends potential dif-
ferences that might cause damage.
