Check whether a problem has arisen in the offset of the compo-

nent recognition camera. *4

If the offset has a problem, the component recognized by the camera

will deviate from the correct position when placed.

Confirm that the offset data of the component recognition camera is

correctly set.

Note: Although the offset data of the component recognition cam-

era can be taught at the “OFFSET TEACH” display, it is

required to re-teach a series of device offset data. (Hierarchi-

cal Sequence: “SPECIAL SEL.” Display → “OFFSET

TEACH” Display)

A special jig is also required for the teaching operations.

Whenever it is necessary to perform the teaching operations,

consult our sales personnel for details.

Check whether fiducial marks are proper in size. *1

If the set mark does not match the actually captured image in size, it

will result in false recognition, positional deviation, etc.

Check whether the set mark is proper in size.

Check for dust and dirt on the lenses. *2

Dirt and dust accumulated on the lenses may cause false recognition

frequently.

Check that dirt and dust are not included in the captured images.

If necessary, clean the lenses with a lens cleaner.

Check whether the gain and level offset data for the P.E.C. cam-

era is proper, using an actual P.C.B. (P.C.B. on which component

are actually placed). *3

It is required to check the gain and level offset data for the P.E.C.

camera every time the current program is changed to another one.

The gain and level may also differ depending on each production lot

of P.C.B.’s.

Make a P.E.C. recognition test and confirm that P.C.B.’s can be rec-

ognized normally.

If the contrast between the mark and the background is not sufficient,

stable recognition cannot be expected.

While changing the gain and level data, check how the recognition is

made and determine appropriate parameters which enable stable rec-

ognition. Then, enter the parameters in the device offset data.

Check whether the lamps for P.E.C. recognition are “ON”. *4

Check whether the power voltage for lighting is proper.

Open the "P.E.C. RECOG LIGHTING" display and turn on the lamps

for P.E.C. recognition. (Hierarchical Sequence: “SPECIAL SEL.”

Display → “UNIT ADJUSTMENT” Display → “RECOGNITION

LIGHTING” Display → “P.E.C. RECOG LIGHTING” Display)

(Perform the checking for both “CAM-A3” and “CAM-B3”.)

• Confirm that the lamps for P.E.C. recognition lighting are “ON”.

• Confirm that the output voltages of power supply “G21” and “G22”

on Beams A and B are 5.0 ± 1.0 V when the lamps for P.E.C.

recognition are “ON”.

Check whether a problem has arisen in the offset of the P.E.C.

recognition camera. *5

If the offset has a problem, it will result in overall positional devia-

tion of placement.

Confirm that there is no problem in the offset of the P.E.C. recogni-

tion camera.

Note: Although the offset data of the P.E.C. recognition camera can

be taught at the “OFFSET TEACH” display, it is required to

re-teach a series of device offset data. (Hierarchical Sequence:

Perform the operation check on Control DC Power

Supply Units G01, G02, and G03.

The control board may be in abnormal condition.

Check how the connector is connected.

Replace the control board with a new one.

YES

Press the [POWER ON]

button for approximately 2

seconds to re-supply power

to the machine.

[Release the

[POWER OFF]

button.

Check whether the switch on the rear side of the LCD touch

screen is turned "ON".

Check whether the circuit protector of the LCD touch screen is

tripped.

Check whether Fuse F111 or F112 has melted, breaking the

circuit.
