Fault 11 Temperature monitoring
Subfault: 11.1 Description: Heat sink overtemperature | ||
|---|---|---|
| Response: Output stage inhibit + line contactor unchanged + module bus response "Critical" | |
Cause | Measure | |
Maximum permitted heat sink temperature exceeded. The capacity utilization is possibly too high. | – Reduce the load. – Reduce the rms value of the current. – Reduce the PWM frequency. – Ensure sufficient cooling. – Reduce the ambient temperature. | |
Subfault: 11.2 Description: Heat sink utilization – prewarning | ||
|---|---|---|
| Response: Heat sink utilization – prewarning | |
Cause | Measure | |
High thermal load on heat sink of device, and prewarning threshold reached. | – Reduce the load. – Reduce the rms value of the output current. – Reduce the PWM frequency. – Ensure sufficient cooling. – Reduce the ambient temperature. | |
Subfault: 11.3 Description: Device utilization | ||
|---|---|---|
| Response: Output stage inhibit + line contactor unchanged + module bus response "Standard" | |
Cause | Measure | |
The temperature has reached or exceeded the switch-off threshold. Possible causes: Mean output current too high. | Reduce the load. | |
PWM frequency too high. | Reduce the PWM frequency. | |
Ambient temperature too high. | Ensure sufficient cooling. | |
Unfavorable air convection. | Check air convection. | |
Fan defective. | Check the fan and replace if necessary. | |
Subfault: 11.5 Description: Electromechanical capacity utilization | ||
|---|---|---|
| Response: Output stage inhibit + line contactor unchanged + module bus response "Standard" | |
Cause | Measure | |
Electromechanical components of device overloaded by excessive continuous current. | Reduce the load. If necessary, reduce the rms value of the current. | |
Subfault: 11.6 Description: Electromechanical utilization – prewarning | ||
|---|---|---|
| Response: Electromechanical utilization – prewarning | |
Cause | Measure | |
High load on electromechanical components of device due to high continuous current. Prewarning threshold reached. | – Reduce the load. – Reduce the PWM frequency. – Reduce the rms value of the current. – Reduce the ambient temperature. | |
