3.8.1.2 Operation of Change ID Code Display if “Blank ID Menu During No Activity” is Enabled
If the Configuration Item entitled
“Blank ID Menu During No Activity”
is enabled and none of the
Function Keys
are pressed for a period of 2 minutes, the CDU will display the currently entered
Customer String (e.g., ABC Railroad) for 2 minutes and will then blank the
Function Menu Display
.
This only applies to the Change ID Menu Item and has been provided to reduce distractions to the
locomotive operator.
3.8.2 Entering the Train Length
Before the operator can make use of the Train Length Distance function, the current length of the train
must first be entered. This is accomplished as follows.
1. To view the current train length or enter a new one, press the
MENU UP
or
MENU DOWN
key until
the
Function Menu Display
reads:
“ Change train length: ##### ft “
where ##### is the current 5-digit value of the train length stored in the CDU’s parameter storage
EEPROM memory.
2. The train length is changed in the same manner as the ID code. Use the " " or " " keys to select
the digit(s) to be modified. The current active digit flashes.
Use the
" "
or
" "
keys to increment or decrement the selected active digit.
Once the desired train length has been selected, press the
SET
key to store the new value. The
sonalert will beep once to signal the successful completion of the save of the new train length into
the CDU’s parameter storage EEPROM. For example, if a train length of 3650 feet has been
entered, the
Function Menu Display
will show:
" New Train length: 03650 ft "
3. The units displayed (feet or meters) will be per the configuration selected via the Diagnostic PC as
described in Section 3.8.9.1.
The Train Length Distance counter function is now ready for use.
