Operation
Proper operating technique is important both to fuel economy and the engine’s useful life. Always allow the engine
to reach normal operating temperature before applying maximum power. Avoid sudden throttle changes and high
RPM operation.
Check the instruments
Check the instruments directly after start-up and at re-
gular intervals during operation. The indicators should
be within the green areas.
Coolant temperature: Green zone (75°C-95°C).
Oil pressure, warm motor: Green zone. At idle it is
normal to have a lower value.
IMPORTANT! For engines under continuous ope-
ration lubricating oil levels must be checked at
least every 8 hours. See the chapter
”Maintenance, lubrication system”.
Alarms and error indications
If the EDCIII system receives abnormal signals from
the engine the ”Diagnostic lamp” (1) will begin to blink.
Pushing the ”Diagnostic button” (2) will give a error
code that can assist in locating the problem. Additio-
nal information on error codes and location of pro-
blems is in the chapter ”Problem location”.
The following conditions apply when the Volvo
Penta instrument box is used:
•
In case of excessively low oil pressure or
excessively high coolant temperature the engine
is shut down automatically and the acoustic alarm
is activated.
•
In case of excessive charge-air temperature and
oil temperature the EDCIII system temporarily
reduces the engine power until the value in
question normalizes. A warning lamp is activated.
•
In case of low coolant level, if the engine is
equipped with a coolant level sensor the engine is
shut down and the acoustic alarm is activated.
The warning lamp is activated.
•
In case of lack of electrical charging a warning
lamp is activated.
•
In case of a fuel warning a warning lamp is
activated.
For other applications we refer to the application
