DIESEL EXHAUST FILTER MONITORING
This unit is equipped with a Diesel Particulate Filter (DPF) to meet current EPA emissions standards. This section
gives an explanation of the indicators that are displayed on the "DPF Status" screen on the Power Zone™ controller.
Diesel particulate filter information can be found on the "Engine" tab within the maintenance screens.
To access the DPF Status page, press any direction arrow ("▲", "►", "▼", "◄") to enter the maintenance screens,
and then press the "▼" directional arrow on the "Engine" tab to toggle through pages until the "DPF Status" page
appears. There are four areas on the "DPF Status" screen that communicate various information to the operator.
The areas and indicators that appear in those areas are explained here:
•
HEST Lamp (High Exhaust System Temperature): This area will display the Regeneration Underway
indicator above the words "HEST Lamp - Solid" when the unit is in the process of diesel exhaust filter
regeneration. During the regeneration process, the exhaust temperature will be very high.
•
DPF Lamp: This area will display the Regeneration indicator above the words "DPF Lamp - Solid" when
auto exhaust filter cleaning is enabled. When the unit is being operated with auto exhaust filter cleaning
disabled, the indicator will begin to flash above the words "DPF Lamp -Flashing" if the soot load level goes
above 80%.
•
DPF Inhib: This area will display the Disabled Regeneration indicator above the words "DPF Inhib - Solid"
when auto exhaust filter cleaning is disabled.
