Indicator Lamps
The following two lamps are installed on the right-hand operator console of the machine:
"DPF" lamp
"High Exhaust System Temperature (HEST)" lampFunctions of the Lamps
DPF Lamp
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless there is an active warning.On - The lamp will be on when a "warning" is active. The warning will occur when the level of soot in the DPF has reached 80 percent. The lamp will be on when the derate level has been reached. This situation will occur when the level of soot in the DPF has reached 100 percent. The "Warning" lamp will also be flashing. The lamp will be on when the shutdown level has been reached. This situation will occur when the level of soot in the DPF has reached 116 percent. The "Warning" lamp will also be flashing and the "Shutdown" lamp will be on.High Exhaust System Temperature (HEST) Lamp
Lamp check - When the keyswitch is turned to ON, the lamp will come on for 2 seconds. The lamp will then go off unless there is an active warning.On - The lamp will be on during active regeneration when the machine is not operating under load and the outlet temperature of the DPF is more than 450° C (842° F).Operation of the Indicator Lamps

HEST Lamp DPF Lamp Lamp State Description of the Indication Engine State
On On Lamp Check When the keyswitch is moved to the ON position, the lamps come on for 2 seconds and the lamps will then go off. The keyswitch is in the ON position but the engine has not yet been cranked.
Off Off No Faults The exhaust system temperature is below
450° C (842° F). The soot loading in the DPF is normal The DPF is not regenerating.
On Off High exhaust temperature The engine is operating at a low idle speed and the exhaust system temperature is above
450° C (842° F). The lamp will remain on until the exhaust temperature falls below 450 deg C, or the engine is operated above the low idle speed. If the engine is operating at a low idle speed, the exhaust temperature is high during an active regeneration. The exhaust temperature is also high during the cooling period immediately after an active regeneration.
Off On High DPF soot loading The soot loading in the DPF is high. The soot loading in the DPF has reached 80%. The lamp warns the operator that an active regeneration is required.
