This will continue for all the digits and
will go back to the first digit and repeat. If
the push-button is not pressed for 32
seconds the microprocessor will return to
normal and will change nothing. This is
useful if you’re only here to check when
the present service interval will occur. The
operator may also turn power off at this
point and nothing will change in the
microprocessor controller.
To save the changes you have made in the
display, you must press and hold the push-
button while any digit is flashing.
The digit will stop flashing and four
seconds later the microprocessor will reset
any previous events pertaining to the hour
service interval, and install the new
numbers. When the microprocessor is
finished the display will change to “donE”.
The trip switch must now be released to
return to normal operation. If the present
hour-meter is close to 999,999, your new
number may be past the overflow so when
you examine when the hour service event
will occur, the number shown will be less
then the current hour-meter. This is
because the current hour-meter must
overflow and start at zero before the
service event can occur.
2. The second menu item “Ser
diS”(Service distance) will allow you to
program the mileage service interval.
The description and operation are the
same as number 1 above except the mileage
service interval is changed or observed.
3. The third menu item “Clr HrS” (Clear
Hour Service) allows you to clear the hour
service flag and automatically reset the next
hour service.
The calculation will use the previous
interval value. When the operator stops at
the “Clr HrS” display and waits four
seconds the service interval will be
changed.
4. The fourth menu item “Clr diS” (Clear
distance) allows you to reset the mileage
service interval.
The implementation is the same as number
3 above.
5. The fifth menu item “PPgn Hi” (Program
High axle) will allow the operator to enter
the pulses per mile or kilometer for the
high axle.
This number will depend on how your
particular sender is arranged. The
maximum pulses per mile or kilometer are
limited to 150,000. When you stop at the
“PPn HI” display and wait four seconds the
microprocessor will display six digits with
the leftmost digit flashing.
The number displayed will be the present
