This Operator's manual describes operation of
Scania instrumentation.
The information in this manual was correct at the
time of going to press. Scania reserves the right
to make alterations without prior notice.
Always use Scania spare parts for repair work.
Overview
The base system consists of a coordinator, coordinator junction box and main junction box. The
main junction box is connected directly to the engine control unit. There are a number of different
options for the base system that can be connected
to the system:
Introduction
• A digital display together with a control panel
with starter key.
• An analogue instrument panel that can be
used instead of the digital display or together
with it.
• An accelerator pedal sensor.
• A remote control (for marine engines only).
The entire instrumentation system is Plug and
Play which makes it very easy to install.
This Operator's manual only describes the analogue instrument panel, remote control, digital
display and control panel.

Engine speed setting 1 and 2
Note:

321 169
Engine speed setting 1 is an engine speed set between high and low idling. High and low idling
vary depending on the engine. The engine speed
is set with control 3.
Engine speed setting 2 is an engine speed that is
set between 450 and 2,000 rpm. The engine
speed is set with control 4.
For both engine speed settings, torque limitation
can be set via either the digital display or using
SDP3. The engine speed settings are isochronous, i.e. the engine speed is held constant irrespective of load.
When either of the engine speed settings is activated, the engine speed goes up or down to the
last saved engine speed.
Control panel
In order to activate engine speed setting 1 or 2,
the engine must be running, the active panel indicator lamp must be on and the throttle must be
at 0%.
Change the engine speed:
• Activate engine speed setting 1 or 2 with control 3 or 4.
• Adjust engine speed up or down with control
1.
• Save the new setting by holding control 2
down for 3 seconds.
If the setting is not saved, the engine uses the last
saved value next time engine speed setting is activated.
This is how to switch off the engine speed settings:
• Press control 5, touch the accelerator pedal or
switch off the engine.

Setting range:

Set the engine idling speed:
• Hold control 2 down for 3 seconds. This will
take you to the adjustment mode.
• Adjust idling up or down with control 3.
• Save the new setting by holding control 2
down for 3 seconds.
It is also possible to change engine idling speed
with the digital display or using SDP3.
Control panel
In order to change the idling speed setting, the
coolant temperature must be higher than 50°C
(122°F) with the engine idling.
Limp home mode
Limp home mode is a marine engine function
that is activated if the coordinator or accelerator
pedal fails or if CAN communication is not
working.
If one of these occurs, the indicator lamp for limp
home throttle control 6 and limp home throttle
control 7 is connected.
The limp home throttle consists of a potentiometer on the control panel which can be used to
limp home. The potentiometer value goes directly to connector A2 on the engine control unit.
In order to use the limp home throttle control, the
potentiometer must first be turned to the 0 position and then activated.

4. Stop button
The remote control for marine engines is connected on connector C4044 on the main junction
box. The remote control can be used to lock the
engine so that it cannot be controlled from anywhere other than where the remote control is located.
This can and should only be done when the boat
is moored, i.e. when there is no risk that the boat
will drift out of control. There is a sign on the remote control with this warning text.
There are 2 positions for key switch 3: Local and
Remote.
Remote control
• Local: The engine cannot be controlled from
anywhere other than from the remote control.
• Remote: Normal position, i.e. the engine can
be operated from the other throttle control positions.
When Local mode is activated, the green indicator lamp 1 comes on. At the same time the active
panel indicator lamp on the control panel starts to
flash, which indicates that the control panel cannot be activated.
When the engine is started from the remote control via starter button 2, it only runs at idling
speed whileLocal mode is activated and no other
throttle control can be used.
If the key switch is reset from Local to Remote
when the engine is running, the green indicator
lamp 1 goes out and the engine continues to run
at idling speed. Other control positions can however take command of throttle control, if the control panel is activated. If key switch 3 is reset
from Remote to Local while running, nothing
happens, but this will be regarded as an unintentional action.
If CAN communication fails when the engine
has been started from the remote control, the engine will stop, but the limp home throttle pedal
will not be engaged.
In order to start the engine again, it is necessary
to carry out the following connection:
• Connect pin 50 on the starter relay to the positive pin on the starter motor. The engine
OPM 500 en-GB 13

starts but it is only possible to control the
throttle using the limp home throttle control.
In order to switch off the engine you must switch
off the power to the engine control unit by turning the starter key to 0. Alternatively you can
switch off the power via connector C4027 in the
main junction box.
Digital display
The digital display shows engine data and any
alarm systems and fault codes. But the display
can also be used to set certain parameters in the
engine control unit.
Digital display
Function
The information content can be found in different screens according to a tree structure. The are
6 different screens at the top level:
• 3 favourite screens
• Information
• Diagnostics
• Settings
The buttons on the display have different functions depending on which screen is active. Use
buttons 1 and 5 to scroll between the different
screens at the top level, depending on which direction you want to go in the loop.
When one of the favourite screens is active, the
information about each button's function is hidden. The reason for this is to make as big an area
as possible available for presentation. When a
button is pressed, the description of the buttons is
displayed for about 5 seconds. Each window
apart from the favourite screens is numbered at
the top left. The numbering indicates the favourite screen and the level of the structure you are
on.

All alarms must be acknowledged before the
next screen will be displayed.
