Code: C-1245
Classification: SD: SD-513 abnormality
Cause:
After the horizontal conveyance roller pressure release motor/1 (M7) starts the home position search operation, the horizontal conveyance roller pressure release home sensor/1 (PS6) does not become active within a specified period of time.
Measures to take when alert occurs:
The main body and the option stop immediately.
Estimated abnormal parts:
- Horizontal conveyance roller pressure release home sensor/1 (PS6)
- Horizontal conveyance roller pressure release motor/1 (M7)
- SD drive board (PCB2)
- SD control board (PCB1)
Press the help key to activate and deactivate the sub power switch (SW2) of the main body.
Note:
- Faulty part isolation allows you to use the machine temporarily.
- The message "Please call service" and "Press [Help] to disengage" are alternately displayed.
- When you press the help key, the message "Please turn on the power again" is displayed.
Solution:
- Check the horizontal conveyance pressure release drive section, and if there is any abnormality, clean or repair it.
- Check the connector connection and the wiring harness between PCB2 and the motor, PCB1 and the sensor. Then, repair them when there is any abnormality.(Wiring diagram: SD-513 (1/2): 6-N) (Wiring diagram: SD-513 (1/2): 22-B).
- Check the connector connection and the wiring harness between PCB2 and PCB1, and if there is any abnormality, repair them.
