This chart shows that board B on the WAIT sensor which
has been carried in from the IN buffer is removed.
This chart shows that board B once removed is returned on the
centering station which is not detected by the WAIT sensor.

Carriage, completed
[Key operation]
When the board carried in from the IN buffer is detected by the WAIT sensor, the
IN buffer is internally latched as "board loaded" condition. Therefore, in this
case, carriage is completed normally as board B is detected as expected after
board A is carried out.
However, if board size is large, or depending on the position where board B is
placed, the space between A and B is small, and this can be a cause of backup
error. The backup error in this case is regarded as normal as software, and this i
s
noted in the operation manual for the users.

CENT buffer error
[Key operation]
When the board carried in from the IN buffer is detected by the WAIT sensor, the IN
buffer is internally latched as "board loaded" condition. If board B is removed in this
condition, a timeout error occurs expecting board B to be carried in at the centering
station after board A is carried out.

This chart shows that production of
board B has been completed, waiting for
board A to be carried out.
[Key operation]
There is no latch operation of "board loaded" condition for the OUT buffer
though it is available with the IN buffer. Therefore, when the board on the
OUT sensor is moved out, the next board can be carried in, disregarding the
board carriage completion by turning the motor. Because the OUT sensor
can be installed in a wide range of position, it is noted in the operation manual
to adjust the sensor position for the board which has slits.
