[Key operation]
When the board carried in from the IN buffer is detected by the WAIT sensor, the I
N
buffer is internally set as "board loaded" condition. If board B is removed in this
condition, and is carried into the IN buffer, board B is carried to the WAIT position
while keeping Ready OUT set off (busy). (This operation can be repeated as
necessary.)
If there are slits or the like at the position where board B is stopped after it is
detected by the WAIT sensor, there are two possibilities.
1. Board carry in is stopped for line by setting Ready OUT to off (busy).
2. For manual operation, even if the WAIT sensor is off, the operator confirms th
e
WAIT position. (It shall be noted in the operation manual that a board shall
not be placed in the IN buffer when there is a board at the WAIT position.))
Therefore, when the WAIT sensor is off, there is no problem for the board which is
detected at the IN buffer to be carried to the WAIT
p
osition.

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.
