Individual steps in PRCD autotest
The test passes if the PRCD:
-
Does not trip out at ½
I
N
tests,
- Trips inside predefined time limits at I
N
, and 5
I
N
tests.
Displayed results:
Main result ............. last measured results
Sub-results ............ all results are displayed as sub-results
Ul-pe ...................... voltage UL-PE
Notes:
Consider any displayed warning before starting measurement!
For DUTs with integrated RCD the housing must be opened to access the RCD’s L
output terminal (this should only be performed by a competent engineer).
Mains voltage is applied to the PRCD under test. Do not touch the equipment
under test or the test leads during the test!
HW 4.x or higher:
When PRCD test is enabled in autotest sequence then mains supply voltage is
applied on test socket during earth bond test (if selected in autotest sequence).
