3.3 Block Skip Specifications
The specifications of the block skip function for the FCP IV-3 are as
follows:
• Block Number Restrictions
Block numbers can be set from 0 to 255.
• Managing the Skip Sequence in the Program
When a skip sequence is set in the program using the MCS/2H Editor,
there is no distinction made between a block and device sequence.
Moreover, the skip sequence cannot be cancelled at the FCP IV-3.
• Marks Permissible On One Board
Including fiducial marks, a maximum of 255 marks are permissible.
• Block Skip Mark Restrictions
Size: Set in MCS/2H.
Mark color: The mark should contrast with the board color so that the
camera can read it easily.
Location: Same as fiducial marks.
• Conditions Under Which Block Skip Marks Are Read
When the letter "B" has been entered into the sequence data device
type (W) column, the machine looks for block skip marks.
• Conditions Under Which Block Skip Is Carried Out
An area of a certain size (Size_X, Size_Y) centered around the
coordinate location is inspected. If all this area matches the color
specified for the block skip mark, the corresponding block is skipped.

Chapter 3 Block SkipPart 2
3.4 Points to Remember When Using Block Skip
It is possible for a block skip mark sequence to reference a fiducial mark,
but the fiducial mark sequence must be placed before the block skip mark
sequence.
A block skip that is set using the machine command keys is valid until
cleared by the operator if the program being run does not have block skip
mark sequences. For programs which do have block skip mark
sequences, the block skip flags set at the machine are cleared before each
new board is produced.
If a board which uses block skip marks, is cleared off in the middle of
production and a new board is then added by hand, production on the
new board will continue using the original block skip information of the
previous board. On the other hand, if a new board is loaded into the
machine using the [LOADER] or [AUTO] function then block skip marks
will be read again and the block skip function will be carried out using
this new information.

Chapter 4 Device CheckPart 2
4. Device Check
When parts are replenished or changeover takes place devices that have been
set can be verified, one by one on the display in order to prevent parts from
being mounted incorrectly. This function is referred to as device check. It is
also possible to set this function such that operation does not begin again until
every device has been checked.
4.1 Method and Function
There are two methods of carrying out the device check function. Device
check can be performed on the machine using the command keys or it can
be done with the use of the [PARTS SET] CANCEL/COMPLETE switch.
4.1.1 Performing Device Check on the Machine
The device check function can be made mandatory with the
commencement of automatic operation or it can be carried out as a
command key operation. When device check is to be made
mandatory with the start of automatic operation, the Proper data
item 70: Device Check SW must be set to either "Parts", "Miss", or
"Error". When device check is carried out as a command operation,
setting values in Proper data is not necessary.
When a mandatory device check is carried out with the start of
automatic operation, device check is carried out in accordance with
the setting made in Proper data item 70: Device Check SW.
Furthermore, anytime the production program is changed, device
check is carried out when automatic operation begins again.
Operation is not possible until the device check is completed.
To perform device check as a command operation on the machine
press the following command keys;
[Program] → [Device] → [Check]
Note: For information concerning the command operation procedure
refer to Part 3, "FCP IV-3 Commands".
