3.9.6. ERRoR InDICAtIon
The commonest errors in the case of a test of a residual current device are:
The RCD did not trip out during the test. Now, to ensure the safety of users, a RCD must trip within 300 ms, or 200 ms for a
type S. Check the wiring of the RCD. If it is OK, the RCD itself must be declared defective and replaced.
The RCD trips out when it should not. The leakage currents are probably too high. First disconnect all loads from the network
on which you are performing the test. Then perform a second test with the current reduced (in U
F
check) as far as possible.
If the problem persists, the RCD must be declared defective.
In the case of a non-tripping test in pulse mode:
