2. Errors checking mode (Displaying the protection history)
2.1. Operation specications
Error mode (Displaying the protection history):
When the set is started up in this mode, the error information is displayed.
Starting up:
• Common in all the models
Press the "ON/STANDBY" button to turn on the power while pressing the "STATUS" and "SLEEP" buttons. The error
(protection history display) mode is set.
Now, press the "STATUS" button to turn on the FL display.
2.2. About the display on the FL display
When the "STATUS" button is pressed after setting the error (protection history display) mode is set, a history like the one
shown below is displayed, depending on the conditions.
(1) Normal (when there has been no protection incident)
FLD
N O P R O T E C T
(2) For ASO (when the last protection incident was ASO protection)
FLD
P R T : A S O
Cause: The line between speaker terminals is shorted, or speakers with impedance of less than the rated value.
Supplementary information: As the excess current is detected after operation of the speaker relay, a short on the
speaker terminal and the connected speaker can be identied.
If the power is turned on without correcting the abnormality, the protection function will work about 5 seconds later
and the power supply will be shut off.
(3) For DC (when the last protection incident was DC protection)
FLD
P R T : D C
Cause: DC output of the power amplier is abnormal.
If the power is turned on without correcting the abnormality, the protection function will work about 5 seconds later
and the power supply will be shut off.
(4) For THERMAL (when the last protection incident was THERMAL(A) or THERMAL(B) protection)
FLD
P R T : T H E R M A L A
FLD
P R T : T H E R M A L B
Cause: The temperature of the heat sink is excessive.
If the power is turned on without correcting the abnormality, the protection function will work about 5 seconds later
and the power supply will be shut off.
b
Additional causes of protection can be due to loose connections, associated components, Microprocessor, etc.
When the "STATUS" button is pressed again after the above protection history as shown above is displayed, the normal
display reappears.
