Description
The YRC1000 previously stores the connected CPU boards, and checks if each board properly responds on a startup. This alarm occurs if there is any CPU board which does not properly respond to the YRC1000.
Subcode description
The ASF01#7 board did not respond when control power was turned ON.
Causes and remedies
| Cause | Remedy |
|---|---|
| Software (incorrect setting) | Check the following settings. • Control group setup in maintenance mode • Rotary switch setting on the ASF01 board for the corresponding station number (6) • Rotary switch setting on the SDCA01 board for the corresponding station number (SV#7) (6) |
| Cable (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, check that the following cables and connectors are connected and fully inserted. • Cable for connector CN207 on the ASF01 board • Cable for CN509 on the SDCA01 board • Cable for connector CN515/516 on the SDCA01 board • Cable for connector CN111 on the AIF01 board • Cable for CN155 on the CPS control power supply unit |
| ASF01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the ASF01 board. Save CMOS.BIN before replacing the board. |
| ACP01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the ACP01 board. Save CMOS.BIN before replacing the board. After replacing the ACP01 board, remove the SD card from the original ACP01 board and insert it into the new ACP01 board. |
| AIF01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the AIF01 board. Save CMOS.BIN before replacing the board. After replacing the AIF01 board, load CMOS.BIN saved before the alarm occurred. |
| Other | If the alarm occurs again after implementing the countermeasures, contact our service department and describe the circumstances when CMOS.BIN was saved (operating procedure, etc.). |
