Configure overload switch-off
You can configure the overload switch-off for each output voltage individually.
The configuration of the overload switch-off is similar to the selection of a fuse: you select the nominal current and the tripping characteristic.
The nominal current can be set between 1000 and 4000 mA.
Connection | Nominal current in mA | Tripping characteristic |
|---|---|---|
1 | 8000:12 „Nominal Current Us“ 8000:13 „Nominal Current Up“ | 8000:11 „Characteristic“ |
2 | 8010:12 „Nominal Current Us“ 8010:13 „Nominal Current Up“ | 8010:11 „Characteristic“ |
3 | 8020:12 „Nominal Current Us“ 8020:13 „Nominal Current Up“ | 8020:11 „Characteristic“ |
4 | 8030:12 „Nominal Current Us“ 8030:13 „Nominal Current Up“ | 8030:11 „Characteristic“ |
If the nominal current is exceeded, the status bit "Warning" is set.
Examples of maximum switch-off times
The following table shows the maximum switch-off time of the overload switch-off for different currents and tripping characteristics.
 | Shorter switch-off time with current limitation The switch-off times shown only apply to output currents below the current limit. If the current limitation is active, the output may be switched off earlier than the configured switch-off time. |
