Engine program
Non-compliant engines
EU Stage II compliant engines
*) = Standard with dual speed configuration. The engine speed can be switched between 50Hz / 60Hz via the Coordinator/EMS.
Note! that the default setting is 50Hz from factory.
To manually change the nominal speed please refer to the installation instruction documentation 19:01-20in the workshop manual or the ‘CAN specification’ and ‘EMS/S6 software function description’located on SAIL at http://sail.scania.com.
