Test setup:
|
|
## Levels of EMC environment as per standard 61000-4-4:
|
|
- Crate
|
|
* **level 1**: well protected environment (e.g. computer room)
|
|
- 2x Hartmann PSUs
|
|
* **level 2**: protected environment (e.g. control room of instustrial plants)
|
|
|
|
* **level 3**: (5kHz, 100kHz, 2kV to power lines, 1kV to signal ports): industrial environment, no surpression of bursts, poor separation of industrial circuits, poor separation of power and signal cables
|
|
|
|
* **level 4**: (4kV to powerlines, 2kV to signal lines): heavy industrial, power plants, rely rooms
|
|
|
|
|
|
|
|
*Possible test results*
|
|
|
|
* **A** - good performance
|
|
|
|
* **B** - some interuption that disapears after stopping test - automatic recovery
|
|
|
|
* **C** - temp loss of function but requires intervention (need to reset)
|
|
|
|
* **D** - not recoverable loss

### Performed tests
|
|
level 1: well protected environment (e.g. computer room)
|
|
|
|
level 2: protected environment (e.g. control room of instustrail plants)
|
|
|
|
level 3 (2kV, 5kHz or 100 kHz, for signal ports 1kV): industrial environment, no surpression of bursts, poor separation of industrial circuits, poor separation of power and signal cables
|
|
|
|
level 4 (4kV to power and 2kV to signal lines): heavy industrial, power plants, rely rooms
|
|
|
|
|
|
|
|
A - good performance
|
|
All timestamps in local time, tests performed according to the 61000-4-5 standard.
|
|
B- some interuption that disapears after stopping test - automatic recovery
|
|
|
|
C - temp loss of function but requires intervention (need to reset)
|
|
|
|
D - not recoverable loss
