KIT-FUEL INJECTION PUMP 1183740 - Caterpillar

Amber Warning Lamp - This lamp indicates that the soot load has increased. Active regeneration or stationary regeneration is required.
DPF Lamp - This lamp provides a general indication of the soot load. The lamp is off when the soot load is low. This lamp is on when an active regeneration or stationary regeneration is required in order to reduce the soot load. The lamp flashes when the soot load has increased to a very high level. The lamp also flashes whenever the ARD disable switch is activated.
High Exhaust System Temperature Lamp (HEST) - This lamp is illuminated when the exhaust temperature is greater than 450 °C (842 °F) and the vehicle speed is less than 8 km/h (5 mph).
Red Stop Lamp - This lamp indicates that the soot load is very high. ARD Lamp - This lamp is illuminated whenever the ARD disable switch is activated.Switch Inputs
The engine aftertreatment system may not require input from the operator in order to work correctly. Operator input may be necessary under certain operating conditions. A flashing DPF lamp notifies the operator when intervention is necessary. The switches are optional. A vehicle may be retrofitted with the switches.Two switch inputs are provided. The inputs can be provided by a single switch or by two ARD switches.Single Switch
Top Position
Illustration 1 g01356895
The top position for a single switch initiates a stationary regeneration when all of the following conditions are met:
The soot load is level one or higher. The DPF lamp is illuminated or the DPF lamp is flashing.
The coolant temperature is greater than 60 °C (140 °F).
The exhaust temperature is greater than 100 °C (212 °F).
The air inlet shutoff is not activated.
The clutch is disengaged.
The brake pedal is released.
The transmission is in neutral.
The throttle position is less than seven percent.
The parking brake is engaged.
The vehicle speed is zero mph.
The power take-off switch is off and stationary regeneration is not allowed during operation of the PTO.Depress the switch for at least two seconds in order to initiate a stationary regeneration if the switch is wired directly to the ECM. Refer to the owner's manual in order to determine the operation of this position if the switch is wired to a J1939 device.If all of the conditions are met, the DPF lamp turns off. Note: The engine speed increases to 1400 RPM on C13 and C15 Engines. The engine speed increases to 1200 RPM on C7 and C9 Engines. If the ECM is controlling the cooling fan, the cooling fan is enabled during the stationary regeneration. Stationary regeneration begins.The HEST lamp illuminates while the exhaust temperature exceeds 450 °C (842 °F).The duration of the stationary regeneration depends on the soot load. Engine speed returns to idle when the stationary regeneration is complete.If stationary regeneration is attempted and all of the conditions are not met, the DPF lamp does not turn off. Engine speed does not increase.Middle Position

This position is for normal operation. The engine aftertreatment system operates automatically. Active regeneration occurs according to engine operating conditions.Bottom
