Faults
Amplifier Gain Too High
If Measure > (Unloaded Reference x (100% + Tolerance%)), an Amplifier Gain Too High fault is
recognized. once this fault is happen, do the following checks:
o Make sure there is good connection between speaker and IDA8C/S.
o Ensure the speaker is a good one.
o Check gain of amplifier, maybe the value is changed after get reference.
If all check passed but still get a amplifier too high fault, change amplifier.
Amplifier Gain Too Low
If Measure < (Full Unloaded Reference x (100% - Tolerance%)), an Amplifier Gain Too Low fault
is recognized. once this fault is happen, do the following checks:
o Check if the signal goes into amplifier is too large, some amplifier has an indicator "Overload",
you can check this indicator.
o Check if speaker is good or damaged.
If all check passed but still get a amplifier too low fault, change amplifier.
If this fault generated after speaker configuration changed, you can do a get reference again to
get new values for reference.
Amplifier Fail
Measure < (Unloaded Reference / 10), once this fault is happen, do the following checks:
o Check if amplifier is power on or not.
o Check if the gain of amplifier is set to 0, if it is, set to a suitable value.
o Check if the wires between amplifier and IDA8 are good connection.
If all check passed but still get a amplifier fail fault, change amplifier.
