• DPF Inhib: This area will display the Disabled Regeneration indicator above the words “DPF Inhib - Solid”

when auto exhaust filter cleaning is disabled.

• Alarm: This area will display the Engine Alarm indicator above the words “Alarm - Solid” when an alarm

condition occurs. This area displays different text depending upon which alarm condition occurs.

For more information on the operation of auto exhaust filter regeneration and service regeneration, refer to “Exhaust

Filter Cleaning Operations” on page 29.

WET STACKING

The unit is powered by a diesel engine. Diesel engines are susceptible to wet stacking if lightly loaded. Wet stacking

occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the

exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load.

It can also cause fouling of injectors and buildup on engine valves. Diesel engines operate properly when applied

loads are between 30% and 100% capacity. Appropriate generator sizing is determined by the anticipated load. If

the unit is in a wet stack condition, load the unit heavily for five hours or until the exhaust is clear.

Wet stacking in the exhaust system is less likely to occur in iT4-certified engines because of regeneration of the

Diesel Particulate Filter (DPF). During the regeneration process, exhaust temperatures are increased to burn off

accumulated particulate, and in the process also removes any un-burned diesel fuel or engine oil in the exhaust

system. Wet stacking may still be present in the engine due to low cylinder temperatures.

Note: If the unit has a 15% or less load for 10 minutes, “Wet Stacking Alarm” will pop up. The unit will still run but

the controller will be inaccessible. The alarm needs to be acknowledged in order to allow the controller to be accessible

again by pressing the Alarm Mute button.

FINE VOLTAGE ADJUSTMENT

Adjustment of the output voltage from the generator is necessary to provide the correct voltage to the end of the

power line. Voltage adjustment can be carried out at any time on the “Voltage Adjust” screen.
