EG power take-off activation
Function
More information on how power take-offs can be combined is found in the document “Power take-off combinations”.

FunctionThe function is used to activate the power take-off from the driver area and from out-side the cab. The power take-off is controlled by the BCI control unit(Bodywork Communication Interface).

For vehicles with a clutch pedal and EG power take-off, the engine speed controls Engine speed control or Raised idling speed are recommended since these engine speed controls are not affected when the clutch is depressed.

For control of the power take-off to work correctly, the power take-off must always be connected via Scania's bodywork interface.

Adjustment of parameters is done using SDP3 (Scania Diagnos & Programmer 3).

EG power take-off activationFunction

ActivationThe are different requirements for activating the power take-off. Depending on the power take-off type there may be permanent activation requirements and selectable activation requirements. The parameters for selectable activation requirements can be set as required for the particular installation. The activation requirements are there to protect the bodywork equipment.

If all activation requirements are satisfied, the function can be activated via BIC (Bodywork Interface Configuration) and External CAN.

The switch must be of the 2-position switch type.

Permanent activation conditionsOne of the following two combinations of requirements must be satisfied to allow the function to be activated:

• Combination of conditions 1:– Engine running, engine speed above 10 rpm– Vehicle stationary, propeller shaft rotational speed below 50 rpm– Air pressure above 0.5 MPa (5 bar)– Clutch depressed for at least 2.5 secs (does not apply to vehicles with fully

automated Opticruise)• Combination of conditions 2:

– Engine off, engine speed 0 rpm– Vehicle stationary, propeller shaft rotational speed below 50 rpm– Air pressure above 0.5 MPa (5 bar)

Selectable activation conditions• Applied parking brake conditions

If the vehicle is fitted with BCI functionality, then the following activation require-ments can also be used.

• Requirements for neutral position• Reverse gear conditions• Upper engine speed limit for activation• Lower engine speed limit for activation



Activation settingsThere are three different activation settings:1

• Manual• Automatic• Drive position

ManualFor activation using the Manual setting, the fixed activation requirements must be satisfied before the power take-off can be activated with the switch. If the switch is in the on position when the fixed activation requirements are satisfied, the switch must be switched off and on again to activate the power take-off.

AutomaticFor activation using the Automatic setting, activation can take place using the switch before other activation requirements are satisfied. The voltage must be on before the switch is activated, otherwise the switch must be switched off and then reactivated. The power take-off is activated when all activation requirements are satisfied.

Drive positionWhen activating in the Drive mode setting, the same prerequisites apply as for Au-tomatic activation, although the voltage does not need to be switched on before the power switch is activated.

1. Changing the settings requires BCI functionality. Activation with the Manual setting is standard from the factory.



DeactivatingThe request for deactivation is made by interrupting the activating input signal from the switch or via an External CAN request. The power take-off is automatically dis-engaged as soon as one of the deactivation requirements is satisfied.

Selectable deactivation conditions• Applied parking brake conditions

If the vehicle is fitted with BCI functionality, then the following deactivation require-ments can also be used:

• Requirements for neutral position• Reverse gear conditions• Upper engine speed limit for deactivation• Lower engine speed limit for deactivation• Upper vehicle speed limit for deactivation• Lower vehicle speed limit for deactivation

Acknowledgement for activation of power take-off in the instrument cluster.

MiscellaneousInformation that the power take-off is activated is sent to other control units and is also displayed in the instrument cluster.

AcknowledgementThe driver receives an acknowledgement that one of the power take-offs is activated when the indicator lamp in the instrument cluster comes on. The indicator lamp is not unique to a specific power take-off, it is used by all power take-offs in the vehicle. The driver can therefore not determine which power take-off is active.

If the vehicle has BCI functionality, it is possible to use status and warning lamps 2, 8, 9 and 10 to indicate to the driver which of the power take-offs is activated. The indicator lamp is set with parameters in SDP3.

Each power take-off has a unique acknowledgement signal sent to other systems in the vehicle when they need a signal on which power take-off is activated.

Power take-off without acknowledgement sensorIf the power take-off does not have an acknowledgement sensor, the acknowledge-ment signal is created internally in the BCI control unit and tracks the status of the activating output signal of the power take-off’s solenoid valve.



Cylinder balancingThe cylinder balancing function governs the fuel volume injected into each cylinder to reduce engine vibrations at low engine speeds. In certain cases, the load in combi-nation with cylinder balancing can cause engine vibration to intensify. In these cases, the function can be deactivated with the Cylinder balancing parameter in SDP3.

Retrofitting power take-offsIf the vehicle is not prepared for power take-offs or does not have a factory-fitted power take-off, then one can be retrofitted.

The following must be carried out when retrofitting a power take-off:

• Cable harness and BCI control unit must be retrofitted and installed.• The SOPS-file (Scania On-board Product Specification) must be updated.

For vehicles with TMS (Transmission Management System), the following must also be carried out:

• Solenoid valve V111 must be renewed with a solenoid valve for control of EG power take-offs.

• Cable harness and switch must be renewed between TMS and V111.

Note:Contact a Scania workshop for assistance with retrofitting a power take-off.
