Optos

When fitted to the machine rails the diffuse sensors switching threshold can be

adjusted by means of a sensitivity control switch. This ensures that when a board

is fed into the machine (via the transport belts), the sensor output switches to ON.

To achieve an optimum setting carry out the following procedure:

1. Place a board on the rails covering the sensor.

2. Turn the sensitivity control fully anti-clockwise, ensure that the green LED

is extinguished.

3. Re-adjust the sensitivity control clockwise until the green LED illuminates.

4. Remove the board from the rails and confirm that the green LED extin-

guishes and the red LED illuminates.

5. Turn the board 90° and position back onto the rail system (so that the board

lies on top of the rail system as shown in the figure below). Confirm that the

red and green LED’s are extinguished. (If the green LED illuminates, turn

the sensitivity control anti-clockwise until the green LED extinguishes.)

6. Remove the board. Position the board back on the rail system, as in Step 1,

and confirm that the green LED illuminates. Carry out Step 4.

Front Rail Parallelism

WARNING

BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN

WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID

INJURY. THE FOILS ON THE FRONT AND REAR BOARD CLAMPS

ARE VERY SHARP.

NOTE

Ensure Camera X Axis Parallelism (Camera and Vision Systems Module Chap-

ter refers) has been carried out prior to commencing this procedure.

1. In Camera Diagnostics, home the Camera X and Y axes. Select Drive to

Board Stop Position the camera carriage is driven to the rear of the front rail.

2. Raise the printhead and insert the head prop.

3. Select Close System to power down the machine.

4. Carry out either of the following:

a. Remove the camera (refer to Camera and Vision Systems Module Chapter,

Camera and Optical Unit Assembly Removal).

b. If available fit a spare camera assembly bearing to the right hand end of

the camera rail.

5. Fit a Dial Test Indicator (D.T.I.) to the camera carriage bearing.

6. Using the D.T.I. check the front rail parallelism to camera carriage rail over

the length of the 'O' ring support plate to ±0.2mm.
