Overcurrent protection for sum currents
EP92x4-002x determines two types of sum currents:
- Sum current for each individual output (calculated)
US + UP - Sum current for all outputs (measured)
∑ (US + UP)
The overcurrent protection for sum currents is disabled in the factory settings. It can be individually activated and parameterized for each sum current:
Sum current | CoE indices | ||
|---|---|---|---|
Activation „Enable Sum Current Limitation“ | Nominal current „Nominal Sum Current“ | Tripping characteristic „Sum Current Characteristic“ | |
Channel 1: US + UP | 8000:04 | 8000:14 | 8000:11 |
Channel 2: US + UP | 8010:04 | 8010:14 | 8010:11 |
Channel 3: US + UP | 8020:04 | 8020:14 | 8020:11 |
Channel 4: US + UP | 8030:04 | 8030:14 | 8030:11 |
∑ (US + UP) (Sum of all output currents) | F80E:02 | F80E:12 | F80E:13 |
