NOTE: The "F" button can be pressed as often as nec-
essary, with every press the machine updates the
memory of the valve position.
5. The machine displays "SPN 2 ". Lower the wheel
guard to spin the wheel, when the shaft reaches the
balancing speed, machine displays "ACH 2" along with
a beep.
6. Once the spin cycle is complete, the display reads
"CAL CUL" for one second. Machine calculates the
results based on the previous two spins.
From this point, there are three possible procedures to
conclude the match balance routine. These 3 proce-
dures are quite different depending on the results of
calculation.
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" 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” “r" and "tur” “tir" alternatively. This instructs the
operator to turn the wheel and make a double cross
mark (XX) on the right side of the tire at 12 o'clock posi-
tion when the right center position LED turns to green.
See Figure 29.
NOTE: If you do not intend to continue minimization,
you can press the Cancel/Stop Button
If the Cancel/Stop Button is pressed now, machine dis-
plays "Qit Qit" for one and half second to remind op-
erator whether he wants to quit optimization or not. If
one presses Cancel/Stop Button immediately, the pro-
gram goes to procedure 1. If not, after one and half
second, machine returns to the optimization procedure.
To continue with optimization: Deflate the tire and then
turn the valve to point the XX mark on the tire. Remount
tire/wheel onto shaft, press "F" when ready to continue.
1. The machine displays "VAL tOP". Turn the wheel
so the valve is at top position. (12 o'clock) and then
press F Button. The machine stores the valve position.
See Figure 30.
2. The machine displays "SPN 3 ". Lower wheel guard
to spin shaft. Machine displays "ACH 3 ".
