Chapter 2 Diagnostic Codes
2-2
Some notes about the operations of the wheel balancer:
All measured angular positions are related to the mass to balance the wheel; they are not the positions of the
imbalance mass itself.
If the balancer is in service mode, some of the normal behavior is changed:
Some error codes will be written into the error record in normal operation mode.
•
This is disabled in service mode, errors will not be recorded.
The number of revolution for a measurement run in service mode is set to
•
- 20 turns (GS, JBEG models)
•
- two times of the C6 setting but minimum 20 turns (CRT, HNA, HWT models)
2.1 IN FIELD REPROGRAmmING OF BALANCER
Turn off balancer.
1.
Place EEPROm in micro-controller socket with flat end at bottom of socket close to large blue connector.
2.
Notched end is 3 spaces short of other end of socket. (IBP) Remove dummie plug and place secure disk into
opening.
Turn on balancer.
3.
Three audible beeps accompanied by three flashes of the led on the micro-controller board indicate that pro
-
4.
gram is loading.
A continuous sequence of beeps and flashes indicates that program loading is complete.
5.
Turn off balancer.
6.
Remove EEPROm and turn on balancer. (IBP) Remove secure disk.
7.
The normal start-up procedure will be performed.
8.
Perform service codes in the following order;
9.
C47
- Select machine model (BFH / Optima)
•
C80
- Calibration of inner SAPE gauge arm
•
C81
- measurement of flange to zero plane distance
•
C82
- Calibration of outer gauge arm (Optima)
•
C83
- Basic calibration of vibratory system
•
C84
- measurement of residual main shaft unbalance
•
C88
- Adjustment of 12 h position
•
C90
- Saving calibration data
•
The machine is now ready for use.
2.2 RECOmmENDED SERvICE STEPS
In case of an error it is recommended to perform some service code to check the system. The following are some
common service codes for this job.
C28
-
Indicate the content of the error record
•
C74
-
Check the incremental encoder of the main shaft
•
C54
-
Some more testing for the incremental encoder of the main shaft
•
C98
-
Check the incremental encoder of the power clamp
•
C63
-
Continuous measurements for test of valid results
•
C56
-
Check the pedal switches. The switches and the Function-Code to lock the power clamp
•
should be checked if the power clamp does not work.
C75
-
Check voltages of SAPE potentiometers (AD8, AD9, AD10) or
•
perform STEP 1 of C80 and C82
C80
-
Check voltages for left SAPE
•
ATTENTION This is a calibration function; interrupt this function after the test in STEP 1
with the STOP or ESC key
C82
-
Check voltages for right SAPE
•
ATTENTION This is a calibration function; interrupt this function after the test in STEP 1
with the STOP or ESC key
C55
-
Check lines voltage
•
C110
-
Check vCC voltage
•
