Activation of EG power take-off
Function
Information on how power take-offs can be combined is found in the document Pow-er take-off combinations.

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

The conditions for when and how the power take-off is to be activated and deactivat-ed are defined in the software tools BICT, (Bodywork Interface Configuration Tool) and SDP3 (Scania Diagnos and Programmer 3):

• A logic diagram defining the factors that will affect the activation of the power take-off is created in BICT. The factors can be, for example, time, rotational speed, torque and vehicle speed.

• The parameters that define the values for how and when the different factors will affect the activation of the power take-off are specified in SDP3.

• The logic diagram, together with the defined parameters, are transferred to the ve-hicle’s BCI control unit by using SDP3.

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

Function


ActivationThere are different conditions to activate the power take-off. Depending on the pow-er take-off type there may be permanent activation conditions and selectable activa-tion conditions. The selectable activation conditions' parameters can be set as required for the particular installation. The activation conditions are there to protect the bodywork equipment.

If all activation conditions are fulfilled, the function can be activated via BCI (Bod-ywork Configuration Interface) or external CAN interface.

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

Permanent activation conditionsOne of the following 2 combinations of conditions must be fulfilled to allow the function to be activated:

• Combination of conditions 1:

– Engine running, engine speed above 10 rpm– Vehicle stationary, propeller shaft 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 au-

tomated Opticruise)

• Combination of conditions 2:

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


Function


Selectable activation conditions• Applied parking brake conditions

If the vehicle is equipped with BCI functionality, then the following activation con-ditions can also be used:

• Reverse gear conditions

• Upper engine speed limit for activation

• Lower engine speed limit for activation


Function


Activation settingsThere are 3 different activation settings:1

• Manual

• Automatic

• Drive position

ManualFor activation using the Manual setting, all the activation conditions must be fulfilled before the power take-off can be activated with the switch. If the switch is in the on position when the activation conditions are fulfilled, 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 the activation conditions are fulfilled. The voltage must be on before the switch is activated, otherwise the switch must be switched off and then be reactivat-ed. The power take-off is activated when all activation conditions are fulfilled.

Drive positionWhen activating with the Drive position setting, the same conditions apply as for Au-tomatic activation, but the voltage does not need to be switched on before the power switch is activated.

1. BCI functionality is required to change the settings. Activation with the Manual setting is standard from the factory.


Function


DeactivationThe request for deactivation is made by interrupting the activating input signal from the switch or via the external CAN interface. The power take-off is automatically dis-engaged as soon as one of the deactivation conditions is fulfilled.

Selectable deactivation conditions• Applied parking brake conditions

If the vehicle is equipped with BCI functionality, then the following deactivation conditions can also be used:

• Neutral position conditions

• 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 and bodywork information in the instrument cluster, it is possible to indicate to the driver which power take-off is activated by us-ing any status and warning lamp. The indicator lamp is set by a parameter in SDP3.

Each power take-off has a unique acknowledgement signal which is sent to other sys-tems in the vehicle when they need a signal about 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 it tracks the status of the activating output signal of the power take-off's solenoid valve.


Function


Cylinder balancingThe cylinder balancing function governs the quantity of fuel injected into each cyl-inder to reduce engine vibrations at low engine speeds. In certain cases, the load in combination 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 EG power take-offsIf the vehicle lacks power take-off preparation or a factory installed power take-off and a power take-off needs to be retrofitted, the following must be done:

• Cable harness and BCI control unit must be retrofitted and installed.

• The SOPS-file (Scania On-board Product Specification) must be updated.

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

Note:Due to the extent of the work, Scania recommends ordering the vehicle prepared for power take-off or with factory mounted power take-off.

Contact a Scania workshop for retrofitting of power take-off.

Connecting and activating a functionElectrical preparation from the factoryTo facilitate the installation of power take-offs there are electrical preparations for power take-offs, refer to preparations from the factory under the heading Chassis conditions.

More information on electrical preparations for power take-offs is found in the doc-uments under Factory-fitted option packages.

The electrical preparation includes power take-off control and cable harness from cab to gearbox. The cable harness and solenoid valve V111 are fitted at the factory which means the following:

• Acknowledgement signal can be connected directly to one of the connectors lo-cated on the right-hand side of the gearbox.

• Air connection for manoeuvring can be made directly to the solenoid valve for the applicable power take-off.
