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
6.2. GND & HI-POT auto-check
265
(1) Pallet moves in the station.(POWER CORD / AV CORD is
267
tightly inserted)
267
(2) Connect the AV JACK Tester.
(3) Controller (GWS103-4) on.
265
(4) GND Test (Auto)
265
- If Test is failed, Buzzer operates.
- If Test is passed, execute next process(Hi-pot test).
265
(Remove A/V CORD from A/V JACK BOX)
265
(5) HI-POT test (Auto)
265
- If Test is failed, Buzzer operates.
- If Test is passed, GOOD Lamp on and move to next
265
process automatically.
