E2-34 Electrical Propulsion Components 2/02 E02016
The following list defines each option:
a. GE engine control
Y: “Fuel Saver” circuitry is installed. The
engine, accelerator and retard pedals inter-
face with the FL275 panel.
N: Accelerator and retard pedals interfaced
with ACC/RET panel.
b. Engine Status (voltage signal from engine sys-
tem fault which inhibits propel):
Y: 0 v trip
N: 28 v trip
NOTE: Y is used for DDEC and MTU engine system
interface for Engine Service and Engine Shutdown
digital inputs.
c. Engine crankcase pressure sensor installed
Y: Analog engine crankcase pressure sensor
has been installed on the engine.
N: Ignore this input.
d. Engine coolant temperature sensor installed
Y: Engine coolant temperature sensor has
been installed on the engine.
N: Ignore this input.
e. Engine coolant pressure sensor installed
Y: Analog engine coolant pressure sensor has
been installed on the engine.
N: Ignore this input.
f. Engine oil pressure sensor installed
Y: Analog engine oil pressure sensor has
been installed on the engine.
N: Ignore this input.
g. APS (Accelerator Pedal Switch) accel inhibit:
Y: 28 v at the “accinh” digital input will inhibit
acceleration.
N: 0 v at the “accinh” digital input will inhibit
acceleration.
h. Two speed overspeed system installed
Y: Loaded/empty load weighing system is
operating on the truck.
N: System not installed on the truck.
i. Optional motor 1 temperature sensor installed
Y: Motor 1 temperature sensor option is
installed.
N: Ignore this input.
j. Optional motor 2 temperature sensor installed
Y: Motor 2 temperature sensor option is
installed.
N: Ignore this input.
k. AS switch overrides retard speed control
Y: Pressing the accelerator pedal will override
the retard speed control system and allow
acceleration with the retard speed control
system turned on.
N: Pressing the accelerator pedal does not
override the retard speed control system.
l. Retard speed control system installed
Y: FL275 panel accepts the retard speed con-
trol system input.
N: Control computer ignores this input.
m. Spin/stall option
Y: Spin stall system is active.
N: Function is turned off.
n. Electric contactor/reverser option
Y: Electric propulsion contactor an reverser
are active.
N: Function is not computed. (Air operated
components are installed.)
o. AT speed spin-correction active above mph
(Enhanced Version 1.00 only)
At speeds greater than the mph number
entered, both wheelmotors are monitored for
evidence of wheel spin and if detected, trac-
tion horsepower is reduced until the spinning
wheel regains traction or until the wheel with
traction falls to the mph value specified.
p. mph OEM option
The number entered is the value in miles per
hour at which the digital output OEM SPEED
EVENT is turned On. When the truck slows to
a speed below this setting, the OEM SPEED
EVENT is turned Off.
