SHUTTING DOWN THE GENERATOR

Check with personnel using power supplied by the generator and let them know that the power is going to be turned

off. Make sure the power shut down will not create any hazards by accidentally turning off equipment that needs to

be kept on (pumps, compressors, lights, etc.).

1. Remove all loads from the generator by opening all circuit breakers (turn to “OFF/O”).

2. Let the engine run for approximately five minutes to allow it to cool down.

3. Push the red Engine Stop/Reset “O” button. Pressing the Engine Stop/Reset “O” button will result in the generator

going into the shutdown cycle and starting a 15 second shutdown timer called “Stopping.” If the unit does not

shut down within 15 seconds, a “Stop Fail” alarm will be displayed on the main display.

4. After the unit shuts down, move the control power switch to the “CONTROL OFF/O” position.

Note: For extended storage time, disconnect the battery. Refer to the engine operator’s manual for extended storage

requirements.

EXHAUST FILTER CLEANING OPERATIONS

When enabled, the exhaust filter system goes through an automatic cleaning process known 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 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. Open the control door and locate the switch labeled “EXHAUST FILTER CLEANING.”

2. Move the rocker switch into the “DISABLED (O)” position.

3. Toggle to the “DPF Status” page on the Power Zone™ controller and verify the Disabled Regeneration

indicator appears above the words “DPF Inhib” (refer to “Diesel Exhaust Filter Monitoring” on page 23

for information regarding the “DPF Status” screen and indicators).

Disabling Auto mode is not recommended for any situation unless it is safety related or if

the fuel tank lacks the required fuel to complete the cleaning process.
