Electrodes on Feeder / Feeder Bank
When electrodes on the feeder bank and the tape feeder get dirty, clean them as follows:
Clean them very lightly to just get rid of the dust with dry cotton swab or nonwoven fabric. Check the pins
for deformation. If you find a bent pin, do not use the feeder as it is. It may result in a flaw on electrodes.
Do not use alcohol, water base detergents and organic solvent, such as
thinner, benzene and acetone.
Do not use sandpaper and tools with sharp blade or edge, such as a knife and
a screwdriver.
NOTE: If they get stubborn stains, try not to get rid of them forcedly. Please contact us.

① Place a production board on the conveyor.
② Turn the Sensitivity Adjuster fully counterclockwise to the sensitivity minimum position. (The
adjuster turns 3/4 rotation overall. If it is turned clockwise, the sensitivity increases, if turned
counterclockwise, the sensitivity decreases.)
③ Turn the Sensitivity Adjuster clockwise slowly and confirm the point “A” where the Orange LED
lights up.
④ Remove the board and continue to turn Sensitivity Adjuster clockwise and confirm the point “B”
where the Orange LED lights up. (If the sensor does not light up, just turn the adjuster clockwise to the
end.)
⑤ Turn the Sensitivity Adjuster to the center of “A” and “B”. Determine the point as a detecting point.
⑥ Put back the board on the conveyor. Be sure that the Orange LED and Green LED light up at the same
time. When you remove the board, only the Green LED should light up.
NOTE: If your machine is equipped with the CE safety conveyor cover, make sure to stick the black rubber sheet
(LG0-M9AA1-00 GOM) on the bottom surface of the cover to prevent mis-detection.
