Can only occur after the end of the self-test:
- Incorrect current transformer type set
- During the self-test the clamp was:
Not stationary
Or a residual current was flowing through it
Or the PGH locating current was flowing through it
- EDS195P hardware faulty
Press the "RESET" button to restart a self test.
No measuring clamp or no measuring current transformer on
the measuring input or incorrect transformer type connected
Measures:
Connect correct measuring clamp or correct measuring current
transformer
A permanent display of pause (- - -) indicates no measurement is
possible.
Steps:
- Hold the measuring clamp still
- Avoid low frequency residual currents
A malfunction has occurred during insulation fault location
Possible causes:
- The measuring clamp was not held still.
- There is a low frequency residual current flowing through the
measuring clamp that is interfering with the EDS measurement
- There a magnetic field around the measuring clamp that is
interfering with the EDS measurement
- EDS195P hardware faulty
If the EDS195 can no longer detect the locating current due to system interfer-
ence and an existing alarm is therefore cleared, an insulation fault will be detect-
ed again at the end of the interference.
