Introduction

Introduction

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.

Note:

Always use Scania spare parts for repair work.

Overview

1

The base system consists of a coordinator, coor-

dinator junction box and main junction box. The

main junction box is connected directly to the en-

gine control unit. There are a number of different

options for the base system that can be connected

3

to the system:

6

• A digital display together with a control panel

with starter key.

7

4

• An analogue instrument panel that can be

used instead of the digital display or together

2

with it.

• An accelerator pedal sensor.

• A remote control (for marine engines only).

5

The entire instrumentation system is Plug and

Play which makes it very easy to install.

Analogue instrument panel

The analogue instrument panel has instruments

for reading engine speed, coolant temperature

and oil pressure. It also has hour counting and di-

agnostic and alarm switches and lamps.

The analogue instrument panel is available in 2

versions, depending on whether the engine is

equipped with an SCR system or not.

The starter lock (8) is used to start and shut down

the engine.

Position 0: The engine electrical system and the

engine are switched off.

Position 1: The engine electrical system is acti-

vated.

Position 2: The starter motor is activated.

Engine speed setting 1 is an engine speed set be-

tween high and low idling. High and low idling

vary depending on the engine. The engine speed

is set with control 3.

6

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

7

SDP3. The engine speed settings are isochro-

nous, i.e. the engine speed is held constant irre-

spective of load.

When either of the engine speed settings is acti-

vated, the engine speed goes up or down to the

last saved engine speed.

In order to activate engine speed setting 1 or 2,

1

9

8

the engine must be running, the active panel in-

dicator lamp must be on and the throttle must be

at 0%.

Change the engine speed:

• Activate engine speed setting 1 or 2 with con-

trol 3 or 4.

• Adjust engine speed up or down with control

1.

• Save the new setting by holding control 2

down for 3 seconds.

Note:

If the setting is not saved, the engine uses the last

saved value next time engine speed setting is ac-

tivated.

This is how to switch off the engine speed set-

tings:

• Press control 5, touch the accelerator pedal or

switch off the engine.

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.

Note:

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 potentiome-

ter on the control panel which can be used to

limp home. The potentiometer value goes direct-

ly 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 posi-

tion and then activated.

The remote control for marine engines is con-

nected 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 any-

where other than where the remote control is lo-

4.

Stop button

There are 2 positions for key switch 3: Local and

Remote.

• 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 po-

sitions.

When Local mode is activated, the green indica-

tor 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 can-

not be activated.

When the engine is started from the remote con-

trol 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 how-

ever take command of throttle control, if the con-

trol panel is activated. If key switch 3 is reset

from Remote to Local while running, nothing

happens, but this will be regarded as an uninten-

tional action.

If CAN communication fails when the engine

has been started from the remote control, the en-

gine 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 pos-

itive pin on the starter motor. The engine
