(1)Contents
| Trouble type | Alignment plate motor/Rrs malfunction | |
| Trouble code | C1140 | |
| Rank | B | |
| Detection timing | <When FS-533 is installed> • The alignment plate home sensor/R (PS109) is not unblocked after the set period of time has elapsed after the plate drive starts from the home position. • The alignment plate home sensor/R (PS109) is not blocked after the set period of time has elapsed when the plate returns to the home position. <When FS-534 is installed> The alignment plate/R home sensor (PS13) is not blocked or unblocked even after the set period of time has elapsed while the alignment motor/Rr (M8) is energized. <When FS-535 is installed> The alignment plate motor home sensor/Rr (PS18) is not blocked even after the set period of time has elapsed while the alignment plate motor/Rr (M12) is energized. | |
