Before you can change anything you must download the DSE Configuration Suite.

You will then need to access the module via the USB config port.

Here you can select ECU options under the engine TAB.

Here you can set the controller for DPF regeneration for ECUs (ECM) which require the engine speed to drop during a manual regeneration cycle. During this time, the generator is not available to supply power and the under speed and under frequency alarms are not active.

To activate select the tick box to 'Allow Non- Mission Regeneration'.
