cator Lamp Lamp State Description of the Indication Engine Status
On On Lamp Check When the keyswitch is moved to the ON po-
sition, the lamps come on for 2 seconds and
the lamps will then go off.
The keyswitch is in the ON position but the en-
gine has not yet been cranked.
If any of the indicators will not illuminate during indicator check, the fault must be investigated immediately
If any Indicators stay illuminated or flash, the fault must be investigated immediately.
Off Off No Faults With the engine in operation, there are no
active warnings, diagnostic codes, or event
codes.
The engine is operating with no detected
faults.
On Solid Off Warning Level 1 warning The engine is operating normally but there is
one or more faults with the electronic manage-
ment system for the engine.
As soon as possible the fault should be investigated.
Flashing Off Warning Level 2 warning The engine continues to be operated, but the
level of importance of the warning has
increased.
Depending on the particular fault and the se-
verity the engine may be de-rated.
The engine could be damaged if continued to
be operated.
Stop the engine. Investigate the code.
Flashing On Engine Shutdown Level 3 warning
If both the warning lamp and the shutdown
lamp are in operation, this issue indicates
one of the following conditions.
1. One or more of the shutdown values for
the engine protection strategy has been
exceeded.
2. A serious active diagnostic code has
been detected.
If installed, the audible warning will sound.
After a short time period, the engine may
shut down.
The engine is either shutdown or an engine
shutdown is imminent. One or more monitored
engine parameters have exceeded the limit for
an engine shutdown. This pattern of lamps can
be caused by the detection of a serious active
diagnostic code.
Contact your Perkins dealer or your Perkins
distributor.
Flash Codes
Some applications may support flash codes. A flash
code can be viewed by an indicator lamp that when
asked will flash in a particular sequence. The
indicator lamp used to view the codes is the warning
lamp, the lamp can then be referred to as a
diagnostic lamp. For more information refer to this
Operation and Maintenance Manual, “Diagnostic
Lamp”.
Aftertreatment System
The aftertreatment indicators should illuminate at key
on for 2 seconds to test the system. If any of the
indicators do not illuminate, the fault must be
investigated immediately.
For more information on the illumination of the
aftertreatment indicators refer to this Operation and
Maintenance Manual, “Selective Catalytic Reduction
Warning System”.
