Operation
30 MMG25I-35D-45I-55DF4 Operating Manual 36949 B
1. Overload of the generator circuits to the connection lugs or the optional cam lock receptacles.
2. The door covering the connection lugs or the optional cam lock receptacles is opened.
3. If the emergency stop switch is activated.
Verify problems that cause the main circuit breaker to trip are corrected before returning the switch to ON (I).
The main circuit breaker interrupts power to the connection lugs and the optional cam lock
receptacles only. The control panel receptacles have power even if the main circuit breaker
is OFF (O). To disconnect power to these receptacles, use the individual circuit breakers
located near each receptacle.
EXHAUST FILTER CLEANING OPERATIONS
When enabled, the exhaust filter system goes through an automatic cleaning process knows as regeneration. Under
normal circumstances, regeneration occurs without interruption of unit operation and with minimal operator involve-
ment. In the event there are conditions requiring the operation of the unit with the auto exhaust filter cleaning disabled,
the operator may be required to perform procedures to enable or disable the auto exhaust filter cleaning. The operator
may also be required to perform a manual regeneration. The following procedures describe how to perform these
functions.
WARNING
The area above and surrounding the exhaust system during an auto or manual exhaust
filter cleaning should be clear of any people and objects. Exhaust gases and compo-
nents can reach temperatures hot enough to ignite and melt common materials.
Note: Always park the unit in a safe location for elevated exhaust temperatures and check for adequate fuel level
before beginning the exhaust filter cleaning process. The cleaning cycle can take an extended period of time
(approximately 45 minutes). Cleaning is complete when the Regeneration indicator remains off.
Disable Automatic (Auto) Exhaust Filter Cleaning
The auto exhaust filter cleaning feature should always be enabled unless doing so would cause an unsafe working
environment. In the event that an unsafe working environment would occur, use the following procedure to disable
the auto exhaust filter cleaning feature:
1. Enter the maintenance screens by pressing ▲, ►, ▼, or ◄.
2. Press and hold () to enter the Running Editor.
3. Press ▼ to move the cursor (blue highlighted text) down to the Engine section.
4. Press () or ► to access the sections. Options should already be highlighted.
5. Press ► and then ▼ to highlight DPF Regen Inhibit. Press () to select the check box.
6. Press ▲ to mark the check box.
7. Press and hold () to save the settings. The display should return to the Home screen.
8. Verify the Home screen displays “DPF Regen Inhibit” above the kW meter and the load used gauge.
Force a Manual Exhaust Filter Cleaning
If running the unit with the exhaust filter cleaning function disabled, the DPF Status screen may display a red alarm,
prompting the operator to force a manual exhaust filter cleaning. Use the following procedure to force a manual
exhaust filter cleaning feature:
