2-12
locked or damaged
-
the cable connecting the camera controller board and the rear shift scanner mo
-
tor is unplugged, damaged or missing
-
there is a fault in the motor power supply board
-
there is a fault in the rear shift scanner motor
-
there is a fault in the camera controller board motor drivers
Corrective actions:-
check all items above
25.3
Check Optima rear shift motor missing steps
E406
Affected models : models with optima hardware
Service Codes : C123
Possible causes: -
the rear shift scanner movement is not smooth or it is striking the frame
-
the motor power supply is not configured properly
-
there is a fault in the motor power supply board
-
there is a fault in the rear shift scanner motor
-
there is a fault in the camera controller board motor drivers
-
the cable connecting the camera controller board and the rear shift scanner mo
-
tor is partially unplugged or damaged
Corrective actions:-
check all items above
26.
Check model information
E900
Affected models : All models
Service Codes : C47 to set model
The stored machine model is not known.If the trouble signalled by the error code is not remedied (using
service codes C47), the machine will remain in service code mode.
27.
Check calibration
E901
Affected models : All models
Service Codes : C80, C81, C82, C83, C84, C88, C90
machine was not calibrated. For calibration the following calibration codes will have to be carried out in
the sequence as given below:
C80 – Calibration of inner SAPE gauge arm
C81 – measurement of flange to zero plane distance
C82 – Calibration of outer gauge arm
C83 – Basic calibration of vibratory system
C84 – measurement of residual main shaft unbalance
C88 – Adjustment of 12 h position C90 – Saving calibration data
28.
Hardware test disturbed
H 82
Affected models : All models
Service Codes : All codes available for the model
A self test was disturbed (e.g. wheel was rotated during the transducer test)The code is read out for 3
seconds, then measurement is repeated (10 times maximum), or aborted using the STOP or ESC key.
29.
Check Optima main shaft encoder zero mark
C1- ---
Affected models : All models
Service Codes : All codes available for the model
There is an error occurred during the hardware test. The four hyphens replace the digits 0 to 9 and the
letters A to F which all characterize an error/defect. The following test will be performed:
1. Power supply voltage (235v)
2. 5v line
3. Incremental encoder (Current of opto-electronic LED)
4. Transducer signal available
5. Auto Stop System (voltage for relay)
