10. Procedure of system calibration and parameter setting
10.1 Balancing calibration Important:
Calibration is needed when: a)First time operation; b) Incorrect test
result suspected.
The procedure of calibration:
Put a medium size wheel, mount on the shaft and lock it well. Input the data of the rim.
Press and hold the key
[F]
and key
[C]
. The display reads:
[CAL][CAL],
hold the keys until
the unbalancing position LEDs light on and blinking. Put down the protective cover and press
[start]
key.
After first spin, rotate the wheel until outer LED light fully flash. The display reads:
[ADD] [100]
, which tells to
add 100g(3.5oz) weight to the outer circumference edge of the rim. the 100g must attach on 12 o'clock posi-
tion of rim.
Put down the protective cover, press [start] to proceed second spin.
after second spin, rotate the wheel until inner LED light fully flash. The display reads:
[ADD] [100]
, which tells
to add 100g(3.5oz) weight to the inner circumference edge of the rim. the 100g must attach on 12 o'clock posi-
tion of rim.
Put down the protective cover, press [start] to proceed third spin. When the cycle of spin finished,
the calibration ended with the data memorized in the machine and the display will read:
[End] [Cal]
.
Error shows during balancing calibration.
[Err] [-8-] forget to attach 100g or power board is out function.
[Err][-9-] forget to attach 100g
[Err][-6] sequence of outer and inner attach 100g incorrect.
[Err][-r-] hardware installation was not correct. calibration cannot completed.
PARAMETER SETTING AND UPDATE PROCESS.
ALL COSENG WHEEL BALANCERS HAVE ITS DYNAMIC PARAMETERS ([dF], [I] an d [S]) SET DURING PRODUCTION.
THE VALUES ARE A VAILABLE ON ALABEL C LEARLY POST ED INSIDE T HE WHEEL BALANCER. TO KNOW THESE
VALUES YOU MUST REMOVE THE TOP COVER.
AFTER CHANGING TO A NEW COMPUTER BOARD IT IS REQUIRED THAT THE PARAMETERS ([dF], [I] and [S]) BE COR-
RECTLY SET AND SAVED INTO THE COMPUTER BOARD.
WHEN [dF], [I] and [S] P ARAMETERS VALUES ARE NOT CORRECTLY SET THEN THE ACCURACY OF THE BALANCER
CANNOT BE GUARANTEED. IT IS RECOMMENDED THAT THE PARAMETERS BE PE-RIODICALLY CHECKED FOR
ACCURACY AND CORRECTED IF NEC ESSARY ON AN EXISTING COM-PUTER BOARD.
PARAMETER UPDATE PROCEDURE
Press and hold the
[F]
and
[C]
keys until display lights stop blinking. This takes about 5 seconds. Then pro-
ceed with the following steps.
Press
[a↓]
and
[a↑]
at the same time. The display panel will go blank (no lights). Press the button to start.
First display will automatically show
[dF][nnn]
where [nnn] represents a positive numeric value. The nu-
meric value of [dF] must match the label inside the wheel balancer. To modify press
[b↑]
to increase or
[b↓]
to decrease value.
To go to the second display press
[a↑]
and this will switch the display to show the <I> value in the form
[I.-]
[nnn]
for a negative value or
[I.-¦][nnn]
for a positive value where [nnn] represents a numerical value. To
change the <I> value press
[b↑]
to increase or
[b↓]
to decrease value. Be careful to note that the value is
correctly entered as indicated on the label in the wheel balancer. This value may be negative or positive.
To go to the third display press
[a↑
]
again. This will switch the display to the <S> setting. A value will be
shown as
[S.][nnn]
where [nnn] is always a positive value. To change it to the correct value as listed on the
label press
[b↑]
to increase or
[b↓]
to decrease value.
To go to the fourth display press
[a↑]
again. This will switch the display to the < Buzzer> set-ting. A value
will be shown as
[bee.][nnn]
where [nnn] show either [On] or [OFF]. [On] means the keypad tone is turned
on. [OFF] means the keypad tone is turned off. To changed it by pressing
[b↑]
or
[b↓]
to go the fifth display press of unbalancing value show> setting. A value will be shown as
[EC.][nnn]
where
[nnn] is one of [05], [10] or [50]. [nnn] means the display will show [00] when the unbalancing value less than
[nnn]. To change it press
[b↑]
to increase or
[b↓]
to decrease value.
To complete the process and save the new values (overwrites the old values) into the computer board press
key
[a↑]
