Installation InstructionIntroduction

This installation instruction contains instructions forinstallation, connection and configuration of VolvoPenta instrument panel DCU II.

The installation instruction with appurtenant kit contentis only intended for professional use in Volvo Pentaservice workshops, machine manufacturers and otherauthorized workshops having staff with qualifiedprofessional training.

Volvo Penta disclaims all responsibility for injury topersons or damage to property that may occur as aresult of the failure to follow the instructions, or for workcarried out by unqualified staff.

NOTICE! The illustrations are used in differentinstructions, consequently details may vary betweendifferent engine models. The essential information iscorrect.

DCU II communicates with the engine control unit andhas a number of functions such as the display ofengine data, monitoring and diagnostics. Ininstallations with several DCU units. In installationswith several DCU units, only one unit can be used ascontrol unit. The other unit only displays engine data.

DCU II can be configured for the current installationwith respect to the inputs and outputs that are to bedisplayed; refer to I/O Status, page 14.

See the Operator’s Manual for respective enginemodel on how to operate DCU II.

InstallationIMPORTANT!Read through the entire instruction carefully beforestarting work.

Installation without a bracket provided by VolvoPenta

1 Use accompanying hole template; refer toInstallation Instruction, page 21. Position the holetemplate at the desired screen location.

2 Drill and cut out the installation area with the aid ofa jigsaw along the inside of the line shown on thetemplate.

3 Drill the four holes for the mounting screws (2), M5.

4 Mount the DCU unit according to the descriptionbelow.

Installing in the bracket

1 Mount the DCU unit (1) in the bracket (3) andsecure using the mounting screws (2), M5. Lock thebolts with thread sealing fluid to prevent them fromloosening due to vibrations.Tightening torque 2.7 ±0.1 Nm (2.0 ±0.07 lbf ft).

2 Assemble brackets (2 and 3). Use 4 screws with arubber mount (6) and 8 nuts (7) as shown in thefigure.Tightening torque 10 ±1.5 Nm (7.4 ±1.1 lbf ft)

3 Use a flange screw (5) in the event the bracket hasto be attached to the engine.

4 The display screen is sensitive to a high level ofheat and should be covered with a protective cover(8) when not used.

NOTICE! The protective cover is not included in allkits but can be ordered separately.

Connection

Connection to engineNOTICE! If this is used as a vehicular node, the plus(+) and minus connections (-) in the line must be usedfor the node, otherwise the CAN-bus must begalvanically insulated. The term, vehicular node, refersto systems other than those belonging to Volvo Penta.

1 Connect the harness between the engine and theDCU to the contact labeled ENGINE on the rear ofthe DCU. Make sure that the harness is orientedcorrectly; see figure.The harness to the engine may not be longer than30 meters (98.4 ft).

2 The harness to connector I/O A and I/O B may notbe longer than 3 meters (10 ft). For configuration ofinput and outputs, see I/O Status, page 14.For examples of installation of I/O A/B, seeInstallation Instruction, page 11.

Maximum throttle can be varied between 50-100 % offull scale. The pre-set value is 100 %The speed request can only be overidden if a fault thatcan damage the engine occurs or if a request for CANtakes place via a TSC1 notification.

Set the min and max position of the gas pedal usingthe potentiometers themselves; they can subsequentlybe finely adjusted, (±10 %) using the +/- buttons on thepanel.The back button confirms the setting and moves backin the menu to set the next value.

Potentiometer Position setting5 V 0.2–4.8 V10 V 0.2–9.8 V

Calibrate the min. value upwards 0.1 V from what isdisplayed on the screen to achieve 0% throttle. E.g. 0.5V is displayed; calibrate to 0.6 V.

Calibrate the min value downwards 0.1 V from what isdisplayed on the screen to achieve 100 % throttle. E.g.2.8 V is displayed; calibrate to 2.7 V.
