NOTE : THE "F" BUTTON CAN BE PRESSED AS OF-
TEN AS NECESSARY, WITH EVERY PRESS THE
MACHINE UPDATES THE MEMORY OF THE VALVE
POSITION.
5. The machine displays " ACH SPN 2 ". Lower the
wheel guard to spin the wheel, when the shaft reaches
the balancing speed, machine displays "
--- ACH --- " along
with a beep.
6. Once the spin cycle is complete, the display reads
"
CAL CUL ACH " for one second. Machine calculates
the results based on the previous two spins.
After calculation the machine displays the unbalance
contributions of rim and tire in percentages of total un-
balance to allow operator to evaluate the quality of the
tire or rim. For example, if the total unbalance is 4.5 oz
in which the rim unbalance measured is 3 oz and tire
unbalance is 1.5 oz. In this case, the rim unbalance is
67% of total unbalance and tire is 33%. Machine dis-
plays
“ r “ “ 67” and “ t “ “ 33” alternatively until the
operator presses the “F” button. This function allows
operator to check the unbalance contribution of the rim
and tire. If someone has too large unbalance, operator
can stop the procedure and change the bad rim or tire.
From this point, there are three possible procedures to
conclude the match balance routine. These 3 procedures
are quite different depending on the results of calcula-
tion.
Procedure 1
The imbalance measured in spin 2 has been reduced to
an acceptable amount, less than 2 oz, and it will not be
necessary to continue match balance. The display reads
"
ACH FIN ISH " for one second, and then proceeds to
the normal two-plane balancing mode and displays the
weight imbalance amount and its position for both planes.
Procedure 2
Due to a large amount of remaining imbalance the op-
erator can continue match mount. Machine displays
"
CRS CRS R " and " TUR TIR --- " alternatively. This in-
structs the operator to turn the wheel and make a double
cross mark
(XX) on the right side of the tire at 12 o'clock
position when the right center position LED turns to green.
