The status that the WAIT sensor is set on is reliable. Therefore, when th
e
WAIT sensor is set on, the IN buffer is set in "board loaded" condition eve
n
if the board is not carried into the IN buffer. However, this status is not
latched and if board B is removed during production of board A, the IN
buffer is set in "board unloaded" condition.

There is no latch status for the OUT buffer such as for the IN buffer,
and detection is made simply by on and off of the OUT sensor.

has been carried in from the IN buffer is removed.
This chart shows that board B once removed is placed
between the IN sensor and the WAIT sensor.

[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, after board A is carried out, carr
y
in operation to the centering station is performed by expecting board
B.
