RPM control
To allow easily to control engine RPM from the “engine
room”, a simultaneous acceleration/deceleration function
(RPM+/RPM-), active only when the switch (1) is in the
“ENGINE ROOM” position, and the switch (2) is in IGNI-
TION position.
Acceleration (RPM +)
If, the engine is running, and RPM+ / RPM- push-button (4)
is held down in the “RPM+ position, then engine rpm are
progressively increased. The increase ends when the push-
button is released, allowing the engine to run at the desired
rpm.
Deceleration (RPM −)
If the engine is running, and RPM+ / RPM- push-button is
held down in the “RPM-” position, a progressive reduction in
rpm is obtained. The reduction ends when the push-button is
released, allowing the engine to run at the desired rpm.
The set out engine speed will be kept until the next engine
shut-off.
The engine shut-off resets every previous configuration.
NOTE
The effect of the RPM + e RPM – controls varies according
to the duration of the operation:
it is achieved a very slow variation during the first 3 seconds;
continuing the operation, the regulation becomes much
more effective and enables to complete the full range of the
engine speed in a overall time of about 20 seconds.
CAUTION
Never operate the “BRIDGE - ENGINE ROOM” switch
when the engine is running.
Once the first start-up phase is complete, verify that:
o There are no liquid leaks from the coolant loop pipeline
junction hoses.
o There are no exhaust gas leaks in the hull.
o In order to carry out the cooling system degassing, do as
follows:
1. Venting screw.
Stop the engine, then loose the venting screw (1) carefully to
degas the expansion tank. When the operation is completed,
tighten the screw to the prescribed torque, start the engine
and keep it up for a few minutes. Stop the engine and verify
the coolant level again, fill it up, if necessary.
Make sure that the coolant that flows out is not dispersed in
the environment.
o Complete the instrument panel operation tests as
described in the related Chapters.
o Verify that the power supply voltage across the battery,
after about 15 minutes with the engine running, is no
less than about 26 V.
o Stop the engine and delete any “errors” which may have
been stored in the injection system ECU during the sta-
bilization phases. The error deletion can be carried out
by the diagnostic instrument IVECO SERVICE TOOL.
