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.

The analogue instrument panel has instruments
for reading engine speed, coolant temperature
and oil pressure. It also has hour counting and diagnostic 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.

When a fault code is generated, a symbol is
shown on the display in the tachometer. Acknowledge the fault code by pressing button 1 or
2.
Once the fault code has been acknowledged, the
fault code symbol remains (refer to illustration)
as long as the fault code is active.

Engine speed setting 1 and 2
Note:

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.
