Scania EMS Instrumentation 1 588 955 - part 2
Remote Control Box (RCB)
Remote Control Box is connected on switch C57 on Main Supply Box
(MSB). With RCB it is possible to lock the engine so that it is not
possible to operate it from another position than where the RCB is
located.
Note: This can 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 RCB with this warning
text.
-
There are two positions for key switch S26: Local and Remote.
- Local: The engine cannot be operated from any other location
than from the RCB box.
- Remote: Normal position, the engine can be operated from the
other throttle control positions.
-
When the Local position is activated the green lamp 2 is
illuminated. At the same time the Active Panel lamps on the Scania
Control Panel (Slave and Master) starts to flash, which indicates
that neither of these panels can be activated.
-
When the engine is started from the RCB using S27 it only runs on
idle as long as the Local position 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 lamp 2 will go out and the engine will continue to
run on idle, but it will then be possible to operate throttle control
from other control positions if the Slave or Master panel is active.
-
If key switch S26 is reset from Remote to Local while driving,
nothing will happen, except that this will be regarded as an
unintentional action.
-
If CAN communication fails when the engine has been started from
the RCB the engine will stop but the Limp Home function will not
be engaged.

- In order to start the engine again, it is necessary to carry out the
following procedure:
- Connect pin 50 on the starter relay with the plus pin on the
starter motor. The engine starts but it is only possible to control
the throttle using the Limp Home potentiometer
- In order to stop the engine you must switch off the power to EMS
S6 by turning the starter key to 0 or via switch C122 in the MSB.

Scania EMS Display (SED)
General
Scania EMS Display is a graphic display which represents engine data,
diagnostics which enables settings of certain parameters in the engine
control unit EMS. Scania EMS Display can only be used together with
EMS and the new electrical system adapted for marine use.
Communication to and from the display is carried out via CAN bus,
protocol J1939.
Function
The information content can be found in different screens according to
a tree structure. On the upper level there are six different screens, three
Favourites, Information, Diagnostics and Settings.
The buttons are configured to function differently depending on which
screen is currently active. To scroll between different screens on the
upper level, use button 1 and 5 depending on whether you want to
move forwards or backwards in the structure.
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. As soon as a button is depressed,
the description for the button is displayed for approx 5 s.
Each window (except the favourites) has a number in the upper left
corner. The numbers indicate the current screen and level.
Favourite screen
The screen Favourites is used to display engine data during operation,
more or less equivalent to Scania analogue instrument panel. The
favourite screen can have three different appearances, all on the
highest level.

coolant temperature is below 50°C. If the engine is running on a raised
idle speed for any reason, the idle speed cannot be reset either
28
1588955
LOW TEMP LIMIT (6.5.2)
The lower temperature limit, which has the basic setting 95°C (203°F),
is the level for the alarm and torque reduction if this has been selected.
See page 33 for an example.
It is possible to set this level between 85°C (185°F) and 105°C
(221°F). The lower limit cannot be set above the upper temperature
limit.
HIGH TEMP LIMIT (6.5.3)
The upper temperature limit, which has the basic setting 105°C
(221°F), also makes it possible (in addition to the alarm function) to
stop the engine automatically.
It is possible to set this level between 95°C (203°F) and 105°C
(221°F). The upper limit cannot be set below the lower temperature
limit.
FIXED SPEED 1 (6.5.4)
Setting of upper torque limit:
This is an isochronous idle speed which can be set and activated from
Scania Control Panel. See page 14.
On Scania EMS Display it is then possible to set an upper torque limit
for FIXED SPEED 1. This setting only applies when FIXED SPEED 1
is activated.
FIXED SPEED 2 (6.5.5)
Setting of upper torque limit:
This is an isochronous idle speed which can be set and activated from
Scania Control Panel. See page 14.
On Scania EMS Display it is then possible to set an upper torque limit
for FIXED SPEED 2. This setting only applies when FIXED SPEED 2
is activated.
SAFETY SWITCH (6.5.6)
The safety switch (idle switch) is a safety function in Scania's electrical
system which checks that the accelerator pedal is functioning correctly.
The component is a closing switch that is activated when the
accelerator pedal position is greater than zero.
The function can be disengaged.
Note: A safety function is then disconnected.
FUEL DENSITY (6.5.7)
Fuel density affects the calculation of the engine power and it can be
noted here. Default is 840 kg/m3 and the setting range is
700-1,000 kg/m3.
