EMS (Engine Management
System)
EMS (Engine Management System) is an electronic system with CAN communication (Controller Area Network)
for diesel engine control. The system was developed by Volvo Penta and includes fuel control and diagnostic
function.
Input signals
The control unit receives input signals about engine
operating conditions, etc. from the following components:
- coolant temperature sensor
- charge air pressure and charge air temperature
sensor
- crankcase pressure sensor
- position sensor, camshaft
- speed sensor, flywheel
- coolant level sensor
- oil level and temperature sensor
- oil pressure sensor
- fuel pressure sensor
- water in fuel indicator
Output signals
The control module uses input signals to control the
following components:
- unit injectors
- starter motor
- main relay
- pre-heating relay
Information from the sensors provides exact information about current operation conditions and allows the
processor in the control unit to calculate the correct
fuel injection volume and timing, check engine status
etc.
Diagnostics function
The purpose of the diagnostic function is to detect and
locate any malfunctions in the EMS system, to protect
the engine and to ensure operation in the event of
serious malfunction.
If a malfunction is detected, it is announced by warning lamps, a flashing diagnostic lamp or in plain language on the instrument panel, depending on the
equipment used. If a fault code is provided as a flashing code or in plain language, it is used for guidance
in any fault tracing. Fault codes can also be read by
Volvo's Vodia tool at authorized Volvo Penta workshops.
If there is a serious malfunction, the engine will be
shut down altogether, or the control unit will reduce
the power delivered (depending on the application).
Once again, a fault code is set for guidance in any
fault tracing.
Fuel control
The engine fuel requirement is analyzed up to 100
times per second. The amount of fuel injected into the
engine and the injection advance are fully electronically controlled via fuel valves in the unit injectors.
This means that the engine always receives the correct volume of fuel in all operating conditions, which
offers lower fuel consumption, minimal exhaust emissions etc.

CIU (Control Interface Unit)
The CIU is a "translator" between the control unit
(EMS) and the customer's own control panel. The CIU
has two serial communication links, one fast and one
slow.
The fast one is a so-called CAN link. All data related to
instruments, indication lamps, connectors and potentiometers is controlled by this link.
The slow link manages diagnostic information for flashing codes etc.
Easy Link Instruments
The following Easy Link instruments are available:
- Tachometer / hours counter (fault codes are also
displayed on the tachometer display when the diagnostic button is pressed)
- Coolant temperature
- Oil pressure

Starting
Make it a habit of giving the engine and engine room a visual check before starting. This will help you to discover
quickly if anything abnormal has happened, or is about to happen.
Also check that instruments and warning displays show normal values after you have started the engine.
WARNING!
Never use start spray or similar agents to start an engine. This may cause an explosion in the inlet manifold.
Danger of personal injury.
Before Starting
•
Check that the oil level is between the MIN and MAX
marks.
NOTICE! The oil level can be read both when the
engine is stopped (the STOP side of the dipstick) and
with the engine running (the OPERATING side of the
dipstick).
For filling refer to Oil level, checking and topping up.
•
Open the fuel valves.
•
Check the fuel pre-filter; refer to Draining conden-
sate, fuel system page 51.
•
Check the coolant level and that the radiator is not
blocked externally. Refer to Coolant Level, Check-
ing and Topping Up page 54 and Charge Air
Cooler, External Cleaning page 55
WARNING!
Do not open the coolant filler cap when the engine
is warm, except in emergencies, this could cause
serious personal injury. Steam or hot fluid could
spray out.
•
Check that no leakage of oil, fuel or coolant is
present.
•
Turn the main switch(es) on.
•
Move the engine speed control to idle, and open the
disengageable clutch/gearbox if installed.
IMPORTANT!
Never break the circuit with the main switch while the
engine is running, as this may damage the alternator.

The pre-heating time is adjusted to suit the engine
temperature, and can last for up to 50 seconds both
before and after starting.
The starter motor connection time is maximized to 20
seconds. After that, the starter motor circuit is cut for
80 seconds to protect the starter motor against overheating.

Without pre-heating
1 Depress the ON/OFF-button (6).
2 Press the START-button (2).
Leave the engine to idle for the first 10 seconds. Then
warm the engine up at low speed and under low load.
Never race the engine when it is cold.
Starting
47702660 03-2013 © AB VOLVO PENTA 23
Starting in Extreme Cold
Certain preparations must be made to facilitate engine
starting, and in some cases to make starting possible
at all:
•
Use a winter grade fuel (of a well-known make)
which has been approved for the relevant temperature. This reduces the risk of wax deposits in the fuel
system. At extremely low temperatures, the use of
a fuel heater is recommended.
•
For fully acceptable lubrication, a synthetic engine
oil of recommended viscosity for the relevant temperature should be used. Please refer to the Main-
tenance, lubrication system chapter. Synthetic lubricants are able to manage a wider temperature range
than mineral-based lubricants.
•
Pre-heat the coolant with a separately installed eletric engine heater. In extreme cases, a diesel-burning engine heater may be needed. Ask your Volvo
Penta dealer for advice.
•
Make sure that the cooling system is filled with a
glycol mixture. Please refer to the Maintenance,
cooling system chapter.
•
The batteries should be in good condition. Cold
weather reduces battery capacity. Increased battery
capacity may be necessary.

Starting Using Auxiliary Batteries
WARNING!
Explosion hazard. Batteries contain and give off an
explosive gas which is highly flammable and explosive.
A short circuit, open flame or spark could cause a violent explosion. Ventilate well.
1 Check that the auxiliary batteries are connected
(series or parallel) so that the rated voltage corresponds to the engine system voltage.
2 First connect the red (+) jumper cable to the auxili-
ary battery, then to the flat battery. Then connect
the black (-) jumper cable to the auxiliary battery
and to a location that is somewhere away from the
discharged battery, e.g. the main switch negative
terminal or the negative terminal on the starter
motor.
3 Start the engine.
WARNING!
Do not touch the connections during the start
attempt: Risk of arcing.
Do not bend over any of the batteries either.
4 Remove the cables in the reverse order.
IMPORTANT!
The ordinary cables to the standard batteries must not
be loosened on any condition.
