Volvo Engine Display Control Unit and Display Unit

DCU II (Display Control Unit)

The Volvo Penta DCU II instrument panel communicates with the engines control unit and has a number of functions as control, monitoring and diagnostics.

NOTICE! Settings and the type of engine data presented on the display may vary depending on the installation and engine model. Depending on the installation the DCU II can also be used as presentation display only.

NOTICE! The menus and illustrations shown here are the English version. Refer to the section Settingsto change the display language.

Display

The DCU II basic view shows three main menus.

• VOLVO NGINE DATA (ENGINE DATA), shows current engine data.

• DIAGNOSTICS (DIAGNOSTICS), shows active fault codes.

• SETTINGS (SETTINGS), shows display and engine settings.

Status bar

The status bar with symbols for active malfunctions is shown in the top right of the display.

Alarms and messages

Messages to the operator are of three types, color coded according to degree of severity.

When a message is shown on the display, press OK key to reach the diagnostic menu to get more information regarding registered faults and instructions for remedial actions.

• ALARM (ALARM), red text, the system has detected a serious fault — consult a Volvo Penta workshop immediately.

• VARNING (WARNING), yellow text, the system has detected a fault — consult a Volvo Penta workshop as soon as possible.

• MEDDELANDE (MESSAGE), blue text, non-critical engine message for the operator.

Menus

DU (Display Unit)

The DU is an computerized instrument panel which shows engine working values on an LCD screen. In the display it is possible to show multiple windows with different information, i. g. engine rpm, coolant temperature, fuel consumption and fault messages. At start up, the display performs a self-test. If an constant signal is heard, the system has discovered a malfunction. The display will work but may act in an unexpected way.

The DU is connected between the engine control unit and the CIU or DCU.

Display modes

Press any of button 1–4 to view the function menu for the buttons, apperaring in the lower part of the display. To leave the menu, wait a few seconds or press button

5 (EXIT).

1 Engine

2 Multi

4 Graph

5 Exit

Contrast

In the display modes Engine, Trip and Graph, it is possible to adjust the contrast.

Press button 5 outside the menu and then + (button 4) or – (button 3) to adjust the contrast.

Engine

Rpm and coolant temperature is shown in the upper part of the display. In the lower part it will show trip computer and a fuel level indicator, if these function are installed.

Multi

In the multi mode, button 2, the information can be shown in four windows,analogue or digital. The display toggles between the two when button 2 is pressed repeatedly. By pressing button 5, the right arrow, you choose what information to be shown in the different windows. Press repeatedly on the button that correspond to the window, until desired information is shown.

Trip

To display the trip computer press button 3, Trip

Trip Fuel, since last reset

Fuel Rate, fuel consumption

Trip hours, since last reset

Engine hours, total amount of operating hours Reset by pressing button 3 for three seconds until a beep is heard.

Graph

The information is shown as graphs. Press button 4 repeatedly to choose what information will be shown. The time interval is set in the Configuration menu. If the connection is broken there will be a straight line in the display.

Configuration menu

Press button 5 for three seconds to enter the Configuration menu. Navigate with the up and down arrows, select with the right arrow.

CIU (Control Interface Unit)

The CIU is a "translator" between the control unit (EMS) and the customer's own control panel. The CIU has two serial communication links, one fast and one slow.

The fast one is a so-called CAN link. All data related to instruments, indication lamps, connectors and potentiometers is controlled by this link.

The slow link manages diagnostic information for flashing codes etc.

Easy Link Instruments

The following Easy Link instruments are available:

- Tachometer / hours counter (fault codes are also displayed on the tachometer display when the diagnostic button is pressed)

- Coolant temperature

- Oil pressure

- Oil temperature

- Battery voltage

- Alarm panel

- Turbo pressure
