Voltage: Select the current voltage which connects to the amplifier.
[18K or 20K Zone]/[1K Tone]: Choose to display window based on your tone setting. Please refer
to [Frequency] option on
Faults:
Line A/B Open: If the value of Measure (ohm) is greater than 4000 ohm, this fault can be recognized by
the IDA8C/S. The field of [Measure(ohm)] shows "OPEN". Please see the example of Zone 1 from the
picture above.
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 3 is 53.247 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. Please see the example of
Zone 2, which indicates "S.C." on the field [Measure(ohm)].
