Control Board

Handling Control Board

Note the followings when handling PC boards.

z Do not touch control boards by wet hands.

z Do not handle control boards where there are metal chips around.

z Wear an antistatic wrist strap and connect it with any metal part of the machine.

z Do not put an electrical board on the place where may cause the short circuit.

Adjustment of Board Detection Sensors

This section explains how to adjust the sensitivity of the board detection sensors.

● LE6-M6547-00X PHOTO SENSOR E3Z-LS81 (OMRON）

z Entrance sensor

z Exit sensor

z Exit buffer arrival sensor

■ Adjusting Method

① Place a PCB on the conveyor belt in the direction in which PCBs will be placed for actual production

operation.

② Turn the sensor’s sensitivity volume counter-clockwise (toward “min”) as far as it will go, to set the

sensitivity to the minimum level.

*The volume can be turned 3/4 turns. Turning it clockwise (toward “max”) increases the sensitivity

and turning it counter-clockwise (toward “min”) decreases it.

③ With the PCB detected by the sensor, turn the volume clockwise (toward “max”) gradually, up to the

point (A) where the orange LED (operation indicator) begins to light up.

④ Remove the PCB and turn the volume clockwise (toward “max”), up to the point (B) where the orange

LED begins to light up. (If the orange LED does not light up even if the volume is turned clockwise as

far as it will go, the position to which the volume has been turned clockwise as far as it will go will be

considered to be position (B).)

⑤ The center position between the positions (A) and (B) is set as the adjustment position. With the PCB

detected at that position, check that both orange and green LEDs light up at the same time. Also check

that only the green LED lights up when the PCB is removed.

⑥ When the conveyor cover is provided because of the safety spec., attach a black rubber sheet

(LG0-M9AA1-00X GOM) to the sensor detection position on the bottom of the cover to prevent false

detection.

NOTE: Make sure that the operation selector switch is set to “L” (ON when light is entered).
