Stage the race vehicles by moving them into
the Pre-Stage (if present) and Stage beams (Pre-
Stage and Stage lights on the Tree come on).
To start the race, press the
[0] RUN
key. The
system will automatically check the alignment of
selected test sensors and emitters prior to starting
the Tree. If the alignments are all good after the
[0]
key was pressed, the Tree will begin the starting
light sequence. If a driver interrupts the starting
beam prior to the green lamp illuminating in that
lane, the starting sequence will stop for that lane,
freezing the tree and illuminating the red/yellow
lamps indicating a redlight start in that lane. Once
a driver crosses the starting line, they must cross
the finish line to complete their run. The Tree will
continue to illuminate the red or green lamps until
both lanes have crossed the finish line (or only one
lane crosses the finish line in the case of a BYE
run). When both vehicles cross the finish line, the
Display will indicate the Elapsed Times or Total
Times (ET or ET+RT if selected).
After both lanes have completed their runs,
the Tree will display the redlight conditions of each
lane if Finish Light sequence [1] was selected. The
selected Finish Light sequence will be illuminated
for the winning lane after applying NHRA rules
for reaction time, breakouts, redlights, and first to
cross the finish line. If a printer option is present,
the selected number of timeslips will print.
[Print]
[SLiP]
will display in window after a race when
printing is occuring. Additional prints can be made
by pressing the
[*7] PRINT
key. If a Scoreboard
option is present, the Scoreboard will display the
selected information (ET/MPH/RT).
The Console Display will show the
Left ET
in the upper display and the
Right ET
in the lower
display; a box
[o]
to the left of one ET indicates
the winning lane. After each race, the race data can
be displayed: Press
[1]
to view Reaction Times,
presss
[2]
to view 60 ft times; press
[4]
to view ET.
If an emitter/sensor pair were out of alignment
when the
[0
] key was pressed, the console
will display
[SS-6SF]
[SS-6SF]
in the LED
displays and flash the offending emitter/sensor
pair(s). Pressing the
[*5] ALIGN
keys will enter
alignment mode and the problem can be corrected
by re-aligning the emitter/sensor pair. If sensors
or emitters are damaged and there are no spares
available, options such as 60 foot and Speed can
be turned off (no start test) and the sensors used
on required positions (Finish).
Race results are available for recall and
reprint until the
[0]
key is pressed for a new race.
Dial-in racing is started by pressing the
[6]
DIALIN
key on the Keypad to display current
Dial-ins, then press
[6]
again to enter the Dial-
in for the Left and Right lanes; the next start
will apply the appropriate differential to the
starting sequence of the race. At the end of a
Dial-in race, the Tree will additionally indicate a
bracket breakout if one occurs on either lane by
illuminating the center yellow light if Finish Light
sequence [1] was selected. Dial-in selections can
be checked by pressing the
[6]
key.
