e. Engine full load rpm value
Used when the manual horsepower limit set is
"N". Sets the engine rpm value that the control
system will maintain by automatically adjust-
ing the load. The available range is displayed
at the bottom of the screen when this line is
selected with the cursor. This generally is set
to the rated RPM of the engine.
f. Retard current demand adjust
This line allows entering the adder or reducer
to make the system regulate at the proper
retard current limit by compensating for the
offset error in the isolation amplifiers. Use the
TEMPORARY RETARD CURRENT ADJUST
SCREEN to determine what this value should
be. The number entered (units are amps) can
be + or -, and it will cause the control to
change the retard current limit by that amount.
1. With the truck shut down and control power
ON, measure the output of Iso-amps IA3
and IA4 at terminal "D" and record the val-
ues.
2. Use the higher of the two readings. (1 amp
=0.001 volts). (For example, if the higher
reading was +0.01 volts, the offset is +10
amps.)
3. Using the above example, enter -10 amps
in the temporary screen.
4. Operate the truck and verify the correct
retard limit was obtained.
5. If the correct retard limit was observed in
step 4, enter that number (-10 in this exam-
ple) on this screen to make it permanent.
Note: Items g. through j. are applicable only if truck is
equipped with "Fuel Saver" system and "GE engine
control" on the OEM-ONLY SETTABLE OPTIONS
ENTRY SCREEN is set to "Y".
g. Percent accel pedal travel off request
Used to enter the percent of pot reference
volts at which the accelerator pedal is cali-
brated to have zero accel request.
h. Percent accel pedal travel full request.
Used to enter the percent of pot reference
volts at which the accelerator pedal is cali-
brated to have full accel request.
Note: Refer to "Statex III Electrical System Checkout
Procedure, Throttle System Check and Adjustment" for
accelerator pedal calibration.
E2-36
i. Percent retard pedal travel Off request
j. Percent retard pedal travel full request
Note: Refer to "Statex III Electrical System Checkout
Procedure, Retard System Check and Adjustment" for
retard pedal calibration.
k. Blower pressure fault time
l. Event data collection interval (sec)
m. Propel with dumpbody up limit (mph)
n. Statistical quarter start month (0=jan, 1=feb,
o. Truck identification number
3. When changes are completed, move the cursor
to "LEAVE TRUCK SPECIFICS SCREEN" and
press [ENTER]. This automatically returns the
program to the TRUCK SETUP CONFIGURA-
TION MINE MENU.
Electrical Propulsion Components
Used to enter the percent of pot reference
volts at which the retard pedal is calibrated to
have zero retard request.
Used to enter the percent of pot reference
volts at which the retard pedal is calibrated to
have full retard request.
Use to set the blower fault time delay in sec-
onds. A value between 30 seconds and 101
seconds may be entered if a delay other than
the default setting of 101 seconds is desired.
Used to set the time interval in seconds that
the CPU collects fault data.
Sets maximum forward propulsion speed (0 to
4 mph) with dump body up and override
switch not activated.
2=mar)
Used to set the starting month for the active
calendar quarters on the CPU clock. Example:
0=Jan, Apr, Jul, Oct
1=Feb, May, Aug, Nov
2=Mar, Jun, Sept, Dec
For use by the mine to enter the truck identifi-
cation number. Truck ID shows up with the
event data and must be unique for each truck.
