No half engine - (OFF)
Half engine when cold air inlet temperature is less than 12.5
F), with parking
brake set - (IF COLD)
Half engine all the time, whenever park brake is set - (ON)
N/A is displayed when changing half engine with the DDR or laptop is not allowed in
the engine calibration. The engine may have half engine program as part of that engine
calibration. View "Diagnostic Data List" to see if the engine is currently operating in
half engine mode.
Idle shutdown can be set with the DDR or programming station.
Time: 01 - 99 minutes
Enabled on VSG: Yes/No; this determines if you want the idle timer to shut the engine
down during idle only
Yes (Idle and High Idle)
Yes/No, will flash the CEL 90 seconds before shutdown to allow the driver to press
the pedal that will cancel the idle shutdown, and run until the key is cycled or by
pressing the pedal again.
Ambient Air Temp disallows override: Can be set with the DDR or programming
station. (Override Temp Disable) Lower Limit = XX; Upper Limit =XX. (When upper
and lower limits are set, the operator will only be able to override ISD if the calculated
ambient air temperature is above or below these temperatures. Upper and lower limit
both set to 167
F=disables the feature.
Adding Ambient Temp Sensor: DDC offers an actual ambient temperature sensor.
If the override temperature disable function is wanted by a customer, it is recommended
that this be added (Kit P/N: 23518521, with instructions 18SP397).
Idle speed can be set on the mainframe for some industrial applications to a maximum of 1000
r/min. It is a fixed speed for on-highway engines.
Idle Speed Offset
The Idle Speed Offset is read by the DDR as Idle Adjust.
Idle speed offset can be adjusted from + 100 r/min, to - 25 r/min using the DDR. Maximum
combined speed for automatic transmission applications is 700 r/min. (Some special applications
allow 750 r/min.)
