제품의 설명

DESCRIPTION

설치

1. 앰프의 파워 코드를 AC OUTLET 으로부터 뽑으십시오.

파워 앰프의 fault detection 모듈은 출력레벨 2V RMS(70 or 100V line)
에서 20KHz의 주파수에 의해서 앰프의 작동 상태를 파악하고, 스피커
라인의 접속 끊김을 체크합니다.
Block diagram에서 볼수 있듯이, 20KHz(2V RMS)는 스피커 케이블을 통
해서 detection 모듈로 전달이 되며 앰프의 출력상에서 다른 signal과 섞
이게 된다. 그리고 detection 모듈은 fault를 체크하는 filter를 통해서 20
KHz 주파수를 감시합니다. 

2. FD-200 SLOT의 BLANK PANEL을 제거한 다음 콘넥터(AN601)가
   묶인 케이블타이를 풀어주십시오.

3. FD-200 모듈의 CN601에 콘넥터(AN601)를 연결한 다음 FD-200 
   보드상의 SW1을 ON위치로 설정하십시오.

5. FD-200을 후면 판넬에 부착하십시오.

6. 앰프의 출력 터미널의 COM 단자와 100V 단자를 FD-200의 COM 단자

와 HOT 단자에 각각 결선하십시오.

7. FD-200의 릴레이 접점을 FS-3381(FAULT STAND-BY AMP SWITCHER)

1. Digital Portable Multimeter를 AC 전압 측정 레인지에 설정하고, 측정리
   드를 파워 앰프의 COM과 100V 단자에 연결하시오.
   "OSC LEVEL" 볼륨을 조정하여 전압계가 2Vac RMS(20KHz)가 되도록 설
   정하십시오.

의 릴레이 접점 입력 단자와 결선하십시오.

파워 앰프의 PGM과 PRIORITY 입력 스크류 터미널을 뽑으십시오. 

Ensure amplifier to be adjusted in not being used, I.e. Unplug 

the PGM and PRIORITY input screw terminals.

INSTALLATION

1. Unplug the power cable from a AC outlet.

2. Remove the rear mounted blank panel, and mount the 

    FD-200 in the resultant hole using screws supplied with the module.

3. 

    of CN601 on the FD-200.

4. Set the switch "FD-200" of FD-200 ON/OFF switch on the 

    rear panel of amplifier.
5. Screw FD-200 on the panel.

7. Connect relay contact of FD-200 to the input terminal of relay 

    contact of FS-3381. (FAULT STAND-BY AMP SWITCH) 

6. Connect "COM" of AMP output terminal and 100V terminal 

    to the "COM" and "HOT".

CALIBRATING FD-200 ON POWER AMPLIFIERS

파워 앰프 설치후 FD-200 조정방법.

4. 앰프의 후면 판넬의 FD-200 ON/OFF 스위치를 FD-200위치로 설정

하여 주십시오.

1. Set Digital Portable Multimeter to measure AC voltage and 

    

    Confirm output of power amplifier is 2Vac RMS at 20KHz.

    Adjust "OSC LEVEL" potentiometer(VR602), If necessary. 

주의: Digital portable multimeter는

 

20KHz

 

주파수를 측정할

수 있는 정밀한 계측기를 사용하십시오. 

Note : Use accuracy Digital portable multimeter which has 

FQ test range.

The fault detection module of power amplifier checks operating

conditions of amplifier and disconnection of speaker wiring by 

giving out the sine wave of 20KHz at an output level of 2V RMS

(at 70 or 100V line).

As the block diagram shows, the sine wave of 20KHz(2V RMS)

deliverd to the detection module though speaker cables and 

the detection module detects only the sine wave of 20KHz 

through a filter to check a fault.   

Set "ON" position SW1 on the FD-200 module after connection 

connect across power amplifier COM and 100V terminals

is mixed with other signals on the amplifier output which is

2. Sensivity 볼륨을 시계방향으로 천천히 Sens램프가 점등 될때까지
    조정하십시오. Sens램프가 점등되는 시점에서 약 1~2˚ 정도 더
    돌려 설정을 마무리 하시면 됩니다.
    설정완료후 오디오를 출력하면 램프가 점멸 할수 있으나 에러는
    아닙니다. 

2. Adjusting sensitvity volume to turn on Sens LED. Turn on Sens 

    LED , adjust the volume to 1 ~ 2˚. Finish the setting and operating 

    amplifier, LED can be flicking, but it is not fault.
