the list and then repeatedly pressing the space key.

4.5. Board Detection Sensor

There are five board detection sensors installed on the PCB take-in and take-out paths of

the conveyor.

Figure 4-4. Installing Position of PCB Detection Sensors

The positions and functions of each sensor are as follows:

 Input Sensor: Detects take-in of PCB into this equipment from the previous process.

 Wait Sensor: Detects PCB in the Wait buffer (at the wait position).

 Place Sensor: Detects PCB in the place buffer (at the placement position).

 Quick-Load Sensor: Detects PCB completed placement so that the PCB in the wait

buffer can be loaded quickly.

 Output Sensor: Detects PCB taken out from the equipment.

The conditions for detection may vary depending on the installation method, distance,

and angle and location of each sensor as well as due to dust, external light, shape, and

color of the board. Therefore, sensitivity of a sensor should be adjusted by using the

actual board that will be used. Sensitivity of a board detection sensor is adjusted by

turning a control screw that is attached to each sensor with no PCB present until the green

LED is lighted. The case of no lighting indicates an unstable state.

Sensitivity is then adjusted with a PCB until the red and green LED's are lighted. The

case of only red LED lighted indicates an unstable state.

Warning

Adjusting the sensor or correcting an error while the

machine is ready could result in personal injury.

Be sure to adjust the sensor or correct an error in the stop

status (idle mode) after canceling the ready status.
