Stationary DPF Regeneration
Atlas Copco recommends that the DPF configuration be left in the AUTO mode at all times; however, in the event that a stationary or manual regeneration is desired, the following process should be followed.
Go to the “STATION REGEN” screen. For normal operation this should be “OFF”.
Press the “Enter” button. This function is not password protected.
Use the up/down arrow to change the selection to “ON” and press the “Enter” button.
Go to the “DPF” screen. For normal operation this should be in “AUTO” mode.
Press the “ENTER” button.
This is password protected. Enter “1968”
Use the up/down arrow to change the selection to “ON” and press the “Enter” button.
This will set the unit up for manual regeneration; after a few moments, the regeneration icon should appear, confirming the unit is regenerating.
After completion, Set both STATION REGEN to “OFF” and DPF to unit to “AUTO” mode.
