4.5. Outgoing condition Configuration
- When pressing IN-STOP key by SVC remocon, Red LED
are blinked alternatively. And then Automatically turn off.
(Must not AC power OFF during blinking)
4.6 GND & Hi-pot test
Confirm whether is normal or not when between power
board's ac block and GND is impacted on 1.5kV(dc) or
2.2kV(dc) for one second.
board's ac block and GND is impacted on 1.5kV(dc) or
2.2kV(dc) for one second.
• GND TEST = POWER CORD GND and SIGNAL CABLE
GND
• Hi-pot TEST = POWER CORD GND and LIVE&NUETRAL
• Test Process
• Test Process
1. Check the POWER CABLE and SIGNAL CABLE insertion
condition.
2. Connect the AV JACK Tester
3. Controller(GWS103-4) on
4. GND TEST(Auto)
3. Controller(GWS103-4) on
4. GND TEST(Auto)
- If Test is failed, Buzzer operate
- If Test is passed, execute next process(HI-pot test)
- Remove A/V CORD from A/V JACK BOX
- If Test is passed, execute next process(HI-pot test)
- Remove A/V CORD from A/V JACK BOX
5. HI-POT test(Auto)
- If Test is failed, Buzzer operate
- If Test is passed, GOOD Lamp on and move to next
- If Test is passed, GOOD Lamp on and move to next

EXPLODED VIEW
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These
parts are identified by in the Schematic Diagram and EXPLODED VIEW.
It is essential that these special safety parts should be replaced with the same components as
recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
