# EMC tests of non-rad-tol DI/OT system
|
|
|
|
|
|
Test setup:
|
|
|
- Crate
|
|
|
- 2x Hartmann PSUs
|
|
|
- 1x Non-rad-tol System Board
|
|
|
|
|
|
standard 61000-4-4:
|
|
|
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
|
|
|
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
|
|
|
|
|
|
all timestamps in local time
|
|
|
according to standard: 61000-4-5
|
|
|
1. Surge test on 230VAC power line (testing the Hartmann PSU) - PSU1
|
|
|
1. 500V every 10s into L and N, 20 surges, test start 10:57 - all good
|
|
|
2. 2kV every 10s into L and N, 20 surges, test start 11:03 - all good
|
|
|
2. Surge test on 230VAC power line (testing the Hartmann PSU) - PSU2
|
|
|
1. 500V every 10s into L and N, 20 surges, test start 11:09 - 11:13 - all good
|
|
|
2. 2kV every 10s into L and N, 20 surges, test start 11:13 - 11:16 - all good
|
|
|
