Scania DI13 Installation dimensions Provide a 150 x 120 mm rectangle where the display is to be positioned. There must be at least 70 mm free space behind the display.
- Scania recommends positioning the main display in the engine compartment for the following reasons:
- To ensure that operation and monitoring are close to the engine.
- To minimise the lengths of the electrical cables between the sensors and main display.
- To reduce the risk of electrical interference caused by long electrical cables.
Scania DI13 Auxiliary display (RP)
The auxiliary display is an option and has the same user interface as the main display. The auxiliary display reads the configuration from the main display. This makes it easy to retrofit.
Scania DI13 Control panel
The engine can be started and stopped through the control panel. It can also be used to activate and adjust engine speed settings 1 or 2. The engine installation can be carried out with or without a control panel.
Scania DI13 Network switch
A network switch is only required if more than one auxiliary display is connected to the engine management system. If the system only contains one auxiliary display, it is connected directly to the main display via a crossover network cable.
Scania DI13 Safety module (SDU)
The safety device unit has monitoring and shutdown functions and is a requirement for classified engine management systems. It should be easily accessible so that alarms can be acknowledged in an easy way.
Scania DI13 Junction box
The junction box is used to connect all the parts of the engine management system to the engine. The junction box also contains fuses. It should be easily accessible.
Scania DI13 Gateway
The gateway reads specific messages about position and speed via NMEA 2000, so that the instrumentation can calculate fuel consumption per nautical mile. The gateway cannot process messages other than these. The gateway requires software version 2.11 or later to be installed in the displays.
Scania DI13 Electrical cables
To protect against electromagnetic interference, Scania recommends that all electrical cables within the system are twisted in pairs with 35-40 turns/m. This only applies to external signal cables connected to the system.
Junction box, connection
Minimum connection, The minimum connection required for the system to function is for the pins on connector C4066 to be connected. If the throttle control is to be controlled via the main display, then pins 1 and 2 of connector C4068 must also be connected. Please refer to the electrical system installation manual 03:01 for information on how to connect the throttle control to the engine control unit. If the throttle control is connected to the engine control unit, secondary throttle control cannot be used.
Junction box, components
There are two 20 A miniature circuit breakers in the junction box, one for each battery connection. Depending on the cable length, it may be necessary to fit extra fuses for the electrical cable. The junction box also has a number of blade fuses, diodes and relays as described below.
