5.2.3. Tool Option Inspection
- Method : Press Adj. key on the Adj. R/C, then select Tool
option.
5.3. Ship-out mode check (In-stop)
▪ After final inspection, press In-Stop key of the Adj. R/C and
check that the unit goes to Stand-by mode.
6. GND and HI-POT Test
6.1. GND & HI-POT auto-check preparation
(1) Check the POWER CABLE and SIGNAL CABE insertion
condition.
6.2. GND & HI-POT auto-check
(1) Pallet moves in the station.(POWER CORD / AV CORD is
tightly inserted)
(2) Connect the AV JACK Tester.
(3) Controller (GWS103-4) on.
(4) GND Test (Auto)
- If Test is failed, Buzzer operates.
- 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 operates.
- If Test is passed, GOOD Lamp on and move to next
process automatically.
6.3. Checkpoint
(1) Test voltage
1) 3 Poles
- GND: 1.5 KV/min at 100 mA
- SIGNAL: 3 KV/min at 100 mA
2) 2 Poles
- SIGNAL: 3 KV/min at 100 mA
(2) TEST time: 1 second
(3) TEST POINT
1) 3 Poles
- GND Test = POWER CORD GND and SIGNAL
CABLE GND.
- Hi-pot Test = POWER CORD GND and LIVE & NEUTRAL.
2) 2 Poles
- Hi-pot Test = Accessible Metal and LIVE & NEUTRAL.
(4) LEAKAGE CURRENT: At 0.5 mArms
