If the leakage impedance is lower than the leakage threshold which is defined in [Global
Settings] tab, then a Leakage Occurrence fault is recognized.
If the internal values of monitoring Line A/B become abnormal, the IDA8C/S will detect and
recognize that error, then generate a global fault Line A/B Error. The error status is showed in
the field [Measure(ohm)]. There are three kinds of Line A/B Errors listed below:
Line A/B Open:
If the value of Measure (ohm) is greater than 5000 ohm, this fault can be recognized by the
IDA8C/S. The field of [Measure(ohm)] shows "OPEN". Please see the example on Zone 2.
Line A/B Bad Impedance:
If the value of Measure (ohm) is greater than Reference A&B (ohm) + Tolerance (%), or value of
Measure (ohm) is less than Reference A&B (ohm) - Tolerance (%), this fault can be recognized
by the IDA8C/S. The field of [Diff(%)] shows the percentage of difference. In the figure above, the
difference in percentage of zone 1 is -50.85% which is greater than the tolerance of 25%. A Line
A/B bad impedance is then recognized.
Line A/B Short:
The voltage of pin +, - is monitored by the IDA8C/S, if the voltage is zero. This means there is a
short circuit outside the IDA8C/S. If this fault is detected, the internal relay of a zone will be
open to stop the audio signals to the speaker. The user needs to perform a Reset Monitoring as
described in the preview part of this topic in order to switch the status back. Pleas see the Line
A/B Short example on Zone 3, which makes the audio output to the speaker short. A string "S.
C." will be showed in the field [Measure(ohm)].
5.7.1.5 Normal Amplifier Monitoring
Settings:
First, in Ateis Studio, right click
the IDA8C/S icon.
When the window [Monitoring(Matrix Mode)-IDA8C/S X ] appears, select the [Normal Amplifier
Settings] page.
