DDEC VI ELECTRONIC CONTROLS APPLICATION AND INSTALLATION
3.7
LAMPS
The instrument panel warning lamps, the Amber Warning Lamp (AWL) and the Red Stop
Lamp (RSL), are supplied by the OEM. The functionality of each lamp along with the wiring
requirements are covered separately in the following sections.
3.7.1
AMBER WARNING LAMP
The AWL is controlled by DDEC VI.
The AWL remains ON:
□
For approximately
fi
ve (5) seconds at the start of every ignition cycle
(a bulb check)
□
When an electronic system fault occurs (This indicates the problem
should be diagnosed as soon as possible.)
The AWL
fl
ashes:
□
When the Diagnostic Request Switch is used to activate the AWL to
fl
ash inactive codes
□
During last 90 seconds before Idle Shutdown if programmed for override
□
When Idle Shutdown occurs or the Optimized Idle system shutdown occurs
AWL and PasSmart
AWL is active with PasSmart. When the Passing Speed Duration time expires, the Amber
Warning Lamp on the dashboard will begin to
fl
ash one minute prior to ramping the Vehicle Limit
Speed (VLS) back down to the normal VLS limit. The rampdown event always takes 5 seconds
regardless of the Passing Speed Increment programmed into the ECU. The rampdown alert
can be distinguished from an engine fault warning in that the AWL
fl
ashes for the former and
remains on constantly for the latter.
PasSmart still operates when there is an active engine fault. In this situation the Amber Warning
Lamp goes from constant illumination to
fl
ashing one minute before the VLS limit ramps down.
At the end of the passing event when PasSmart is deactivated, the Amber Warning Lamp will
return to constant illumination if the engine fault is still active.
Amber Warning Lamp Requirements and Guidelines
The following requirements and guidelines apply to the AWL:
□
The AWL is required.
□
A 12 volt light of less than 0.25 A (DC) is required depending on the ignition source.
□
The AWL must be integrated into the instrument panel or placed in clear view of the
equipment operator.
□
The lens color must be amber.
All information subject to change without notice.
