Part 1
• STN 11: Nozzle Change
A nozzle that is compatible for picking the next part is selected
and the nozzle change operation is carried out accordingly.
• STN 12: Nozzle Change Check
A check is carried out to confirm that the appropriate nozzle
has been selected.
If a nozzle change alarm has occurred then the head that has
caused the alarm will stop here.
6.2.5 Parts of the Board Loader System
The FCP IV-3 has three conveyor systems to transport boards and a
table to hold the board during production. These conveyors are
called the in conveyor, the main conveyor and the out conveyor. It
is possible to have one board on each conveyor. Although the
board usually moves from left to right as shown, it is also possible
for the board to move the other way. In this case, the names of the
conveyors remain the same, as do their loading capacities.

6.3 Changing the Original Table
The original device table (that is, the table which is used first) is selected
automatically when a new production program or table mode is selected.
The conditions under which the original table will change are listed
below.
6.3.1 Change Due to Change of Production Program
The original table is determined according to the table mode when
the new production program is selected, as follows:
• Changeover mode (1A 2B)
The original table changes depending on the setting in
Original_table in Machine data, as explained below.
Machine_data
37. Original_table (Non, Table1, Table2)
Non :The table other than the table used until now is
the original table. If table 1 had been used, table 2
will be the original table, and vice versa.
Table1 :When the program has been changed and
foreground transmission has been carried out
table 1 will be the original table.
Table2 :When the program has been changed and
foreground transmission has been carried out
table 2 will be the original table.
When Original_table is specified and many programs have
used the same devices, then parts must be replaced and the
original table specified manually.
• Device Change Mode (1A 2A)
The table other than the table used until now is the original
table. If table 1 had been used, table 2 will be the original table,
and vice versa.
• Joint Mode (JOINT)
There is no original table.

6.3.2 Change Due to Change of Table Mode
• When changing from joint mode to changeover mode, or to
device change mode, table 1 will automatically become the
original table. Note that if the original table is specified in the
program in device changeover mode, that table will be used.
• When changing from changeover mode or device change mode
to joint mode, there will be no original table.
• When changing from changeover mode to device change mode
the original table will remain the same.
When dealing with the operations described in 7.3.1 and 7.3.2, the
next original table number will be displayed. Press [SET],
[STATUS] and [TABLE MODE] to reach command Page 514/000 to
set the original table.
6.4 Device Tables: Part Pickup Position and Resupply Position
There are 2 separate device tables each with 80 device positions. Each
table can be resupplied at its respective resupply position.
If only one device table is used for production, parts for a different
program can be set on the other device table by moving this device table
to its resupply position.
There are 3 possible table modes that can be set to determine how the
device table is to be used. During operation the device table will move
automatically to either its part pickup position or to its resupply position
depending on the following conditions.
