MANAGING THE ENGINE FROM THE RELAY
BOX
By means of the electronic unit indicated as the "Relay Box", installed
close to the engine room so that it can be accessed during mainte-
nance operations and during navigation, it is possible to start and stop
the engine and manage its running speed, while at the same time pre-
venting accidental start-up from the bridge.
The relay box contains the multi-pin connector (6), protected by a
screw-on cover, used to connect to the IVECO MOTORS diagnosis
instruments.
1. Selector for control from bridge or engine room - 2. Engine electric
circuits power supply switch - 3. Button to start from the engine room
- 4. Maintenance alarm" reset button - 5. Button managing accelera-
tion and deceleration - 6. Connector for diagnosis instrument - 7. EDC
blink code indicator - 8. Maintenance interval expired indicator - 9. Bad
engine parameters indicator (WARNING).
The box contains the components that protect the electrical lines
from accidental short-circuits or excessive current absorption. These
components do not require replacing, as the electrical continuity of the
circuit will be restored automatically as soon as the malfunction ceases.
Start-up procedure
1. Turn the switch 1 in the Relay box to the "ENGINE ROOM" posi-
tion. This totally excludes the bridge commands and must never
be carried out when the engine is turning.
2. Turn the switch 2 to the “IGNITION” position to power the sys-
tem's electric circuits and enable the commands on the panel.
3. Press and release the START button (3), to commence the start-
up phase.
