xxviii
The following table shows the errors that may occur. You should note here that if the green tube is replaced it is very important that the green yoke be
placed so there is no tilt. If it is not placed correctly, a repetitive “80” can occur.
* 60, 70 or 80 appears only in Service Mode.
* In case of multiple error, last error is displayed.
(EXAMPLE)
11B :
Left sensor Blue level low. (Left sensor circuit may be faulty.)
61R : “ RED CENT H ” offset overflow. (“ PWM2 ” may be required adjusting.)
00 No Error
10 Sensor Output Level Low * Check wiring, beam position, sensor.
20 Sensor Output Level High * Check OP-amp circuit.
30 Adjustment Loop Counter Overflow 0 : “ CENT V ”
1 : “ CENT H ”
2 : “ SKEW V ”
3 : “ SKEW H ”
40 Regi Data Overflow Same as Loop Counter Overflow
50 Regi Data Overflow Same as Loop Counter Overflow
60 Offset Overflow Same as Loop Counter Overflow
* Check beam position. If need, adjust “ PWM2 ” for H error,
“ V CENT (main) for V error.
* “ PWM2 ” is usually 34 or 36.
70 Offset Overdrow Same as Counter Overflow
* Check beam position. If need, adjust “ PWM2 ” for H error,
“ V CENT (main) for V error.
80 Green “ V SKEW ” too tilt * Adjust Green beam righ or left sensopr, or Green DY tilt.
