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
• C111
- Check belt tension
The following codes allow some deeper tests of the vibratory system:
•
C67
- Indicate the phase stability/shift of the vibratory system
• C72
- Measure the angular deviation of the vibratory system
• C63
- Continuous measurements to check measurement deviation.
