PAGE 129
5 6 7 8 7.3.2 AMPLIFIER SYSTEM PROTECTION OPERATION SPECIFICATION 1. DC-abnormality detection DC detection is only enabled 2 seconds after power-on. If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input, the DC_DET port becomes “L”. If the “L” is detected, the microprocessor will perform as following flow chart. A In the case of simultaneous detection with the overload protection circuit, DC-abnormality detection is performed preferentially to overload detection.
PAGE 130
1 2 3 4 3. XPROTECT detection XPROTECT is started to be monitored 200msec after power on. XPROTECT port is checked every 20msec. If Low level (ERROR) is recognized during consecutive 9 times, micon judge it as XPROTECT ERROR. A It processes more preferentially than DC abnormal detection and overload detection. POWER ON ↓ When 200 msec passed after power on, the XPROTECT detection starts. Don't detect it during power off.
PAGE 131
5 6 7 8 7.3.3 AMPLIFIER FAILURE DIAGNOSIS FLOW CHART Amplifier failure diagnosis flow chart A When DC detection is activated ("AMP_ERR" flashes on the display), failure (damage) of the power amplifier section is considered. As DC detection and fan stop protection circuits commonly use same abnormality detection port in microprocessor, please make sure that the operation of fan motor is in normal condition before proceeding to the troubleshooting of amplifier.
