Just as with device check and nozzle check, the START button will not be enabled if the

stopper position is not set.

The following screen appears when the board distance check function is entered.

Action of the function keys

SET : Press this key after moving the mid-stopper position or reference pin

position to the specified position. This completes the setup.

▲ : Press to move the cursor up

▼ : Press to move the cursor down

RETURN : Press to return to the command selection screen (Page 000).

Note: The information related to the reference pin will only display if the reference pin specification

has been set in Proper data.

For reverse flow machines the display message is as follows.

“Extend IN-carrier when changing conv width

Raise main conv at IN-conv loading position”

When automatic changeover is carried out using HELPS, the above mentioned message

does not display since the conveyors are linked automatically (both standard and reverse

flow).

1.18 Two Camera System

Because some parts require highly accurate placing, the vision processing system uses

two cameras: a wide view and a narrow view camera.

1.18.1 Camera Mounting Position

The position of cameras are shown below.

1.18.2 Wide View Camera and Narrow View Camera

(1) Wide View Camera

The wide view camera has a field of view as described below.

• Using backlighting with an S22 back light disk

The camera can handle a rectangular-shaped part with dimensions of up to 19 mm x

20 mm.

• Using frontlighting with a B22 back light disk

The camera can handle a square-shaped part with dimensions of up to 20 mm x 20

mm.

Generally speaking, the wide view camera can handle parts between size 4532 and SQFP

48 pin. It can also handle parts smaller than 4532 but with reduced placing accuracy.

(2) Narrow View Camera

The field of view for the narrow view camera is up to 9 mm x 9 mm.

This camera can handle parts from as small as 0603 to 3216.

The narrow view camera takes a small part and magnifies the picture so that high

accuracy placement can be carried out.

The narrow view camera can handle parts larger than 3216, but since it computes highly

accurate placing coordinates, vision processing on larger parts takes more time.

0603 (in. 0201) Parts Compatible Camera (Option)

It is possible to mount 0603 (in. 0201) size parts by exchanging the Narrow View Camera

for the optional camera.

Cautions with software

• Use vision software V 2.94 or a later.

• A center measurement cannot be performed using a 0.4 mm nozzle with the Wide

View Camera.

• If a 0.4 mm nozzle is specified as the No. 1 nozzle in the nozzle layout table, a program

transmission error will occur. (Error Code: 11011327).

(3) Data Necessary to Use the 2 Camera System

To make use of the 2 camera system, the following data must be entered into Proper and

Part Data.

Necessary Proper Data

137. Narrow Camera: Use

Set to “Use” when using a NARROW VIEW CAMERA.

Necessary Part Data

To use the wide camera for vision processing, set this entry in vision data to

"Wide_view", and to use the narrow camera set it to "Narrow_view." Use the NARROW

VIEW CAMERA for 3216 or smaller parts.
