Enable: Enable/disable the leakage detection on the corresponded internal/external amplifier/
VO3 channel.
Leakage impedance (ohm): The impedance between the Line A or Line B port and ground wire
causes the current leakage.
Note:
Due to the device component requires to charge, the leakage detection will be
mandatory begin in 3 minutes after the device is powered, so that the leakage impedance
result will be accurate. You will see a countdown time first as the picture below, and the
value of leakage impedance will be shown after 3 minutes. If users do not wish to wait for the
result which is displayed after 3 minutes, click [Leakage Test] button to see the instant
detection of leakage impedance.
Enable all: Enable the leakage detection on all the internal/external amplifier amplifiers.
Fault report threshold: A threshold value for leakage detection. If the measured impedance is
lower than this value, a leakage fault is recognized.
Isolation impedance threshold: If the measured leakage impedance is lower than this
threshold, a leakage fault is recognized and the relay will be opened, this will result in no
audio sound and show in fault list.
Isolation leakage speaker line: By enabling this option, the relay will open to stop audio output
if a leakage fault is detected.
Leakage test: Click this button to start the leakage detection process, the progress status will
show on [Leakage impedance] grid.
5.1.11.4.1 Faults
Leakage occurrence: If the leakage impedance is lower the [Fault Report Threshold] which is
defined on [Leak to Ground] window, then a [Leakage Occurrence] fault is recognized.
Leakage open: The measurement of speaker lines has short-circuit fault due to the + speaker line
is connected to ground wire, and - is connected to ground wire, then a [Leakage Open] fault is
recognized.
