Fault 6 Line fault
Subfault: 6.1 Description: Line phase failure | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Missing line phase detected. | Check the supply system cable. | |
DC link voltage periodically too low. | Check the configuration of the supply system. | |
Inadequate line voltage quality. | Check the supply (fuses, contactor). | |
Subfault: 6.2 Description: Power failure | ||
|---|---|---|
| Response: Power failure | |
Cause | Measure | |
Power failure detected. | Check the supply system cable. | |
Subfault: 6.3 Description: Line overvoltage | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Line voltage exceeds permitted upper threshold value. | Check the nominal line voltage of the project planning. | |
Inadequate line voltage quality. | Check the quality of the power system. | |
Subfault: 6.4 Description: Line undervoltage | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Line voltage dropped below permitted lower threshold value. | Check the nominal line voltage of the project planning. | |
Inadequate line voltage quality. | Check the quality of the power system. | |
Supply system cable missing. | Check the wiring. | |
Subfault: 6.10 Description: Supply system cables swapped | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Supply system cables swapped. | Check the wiring of the line components. | |
Subfault: 6.11 Description: Fault in supply system cable or output stage | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Supply system cable missing. | Check the wiring. | |
Faulty branch of output stage. | Check the device. | |
Subfault: 6.12 Description: Line overcurrent | ||
|---|---|---|
| Response: Output stage inhibit + line contactor unchanged + module bus response "Critical" | |
Cause | Measure | |
Too much current flows in the supply system cable. | Check the line current taken into account in project planning. | |
Subfault: 6.13 Description: Short circuit of line contactor digital output | ||
|---|---|---|
| Response: Output stage inhibit + open line contactor + module bus response "Critical" | |
Cause | Measure | |
Short circuit detected at digital output of line contactor. | Check the wiring. | |
