Step 4) Confirm that R/G/B value is lower than 10 of the "Raw
Data (Sensor data, Back light)". If after 6 seconds,
R/G/B value is not lower than 10, replace Eye Q II
sensor.
Step 5) Remove your hand from the Eye Q II sensor and wait
for 6 seconds.
Step 6) Confirm that "ok" pop up. If change is not seen,
replace Eye Q II sensor.

4.9. 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.
After final inspection, Always turn on the Mechanical S/W.
5. GND and Internal Pressure check
5.1. Method
1) GND & Internal Pressure auto-check preparation
- Check that Power Cord is fully inserted to the SET.
(If loose, re-insert)
2) Perform GND & Internal Pressure auto-check
- Unit fully inserted Power cord, Antenna cable and A/V
arrive to the auto-check process.
- Connect D-terminal to AV JACK TESTER
- Auto CONTROLLER(GWS103-4) ON
- Perform GND TEST
- If NG, Buzzer will sound to inform the operator.
- If OK, changeover to I/P check automatically.
(Remove CORD, A/V form AV JACK BOX)
- Perform I/P test
- If NG, Buzzer will sound to inform the operator.
- If OK, Good lamp will lit up and the stopper will allow the
pallet to move on to next process.
5.2. Checkpoint
• TEST voltage
- GND: 1.5 KV / min at 100 mA
- SIGNAL: 3 KV / min at 100 mA
• TEST time: 1 second
• TEST POINT
- GND TEST = POWER CORD GND & SIGNAL CABLE
METAL GND
- Internal Pressure TEST = POWER CORD GND & LIVE &
NEUTRAL
• LEAKAGE CURRENT: At 0.5 mArms
