Var ’n Warning

Level

While the machine is running, the score for every fiducial located is monitored.

If for a given fiducial, the score from one fiducial to the next varies by more than

the Variation Warning Level, but does not fall below the minimum accept score,

a message window is displayed, warning that the score of the screen/board

fiducial is fluctuating. Fiducial relearning is advised if the problem persists.

Fiducial Search The parameter enables an auto search to be selected if a screen fiducial or board

fiducial are not found. The feature also enables a machine to run a product setup

on another machine, options are:

Setup If Custom is selected, an Adjust option becomes available on the menu bar:

On selecting Adjust from the menu, a Fiducial Search Strategy window opens:

The menu bar changes to:

The Next and Previous keys move the cursor between the two parameters.

The Incr. and Decr. keys change the value of the highlighted parameter.

The Exit key returns to the set preferences menu.

Autosearch This parameter sets whether an automatic search can be selected following a

Fiducial Not Found Error Message. The options are:

The option Auto Search (F2) is added to the menu bar as follows:

Depending on the setting, the option Auto Search (F2) is available for the 1st

board or all boards of a batch, following a Fiducial Not Found Error Message.

If Auto Search is selected, the machine uses the following strategy to search for

the fiducial. The sequence continues until the fiducial is found:

1. The camera starts in the nominal fiducial position, determined by the product

file.

2. The camera attempts to locate the fiducial within its field of view.

3. The camera stays in position and repeatedly searches for the fiducial, each

time using a different adjustment of the camera lighting.

4. The camera moves to another position in the search window area.

5. If the whole search window area has not been covered, the sequence returns

to Step 2.

6. If the the whole search window area has been covered with no fiducial being

found, the camera moves to the nominal position and an error is generated.

NOTE

If 2D board inspection is enabled on a machine this feature searches for screen

fiducials only.

Window Size This parameter sets the size of the window area that is searched around the

nominal fiducial location.

Local Product File The offset values (differences between the product file and set up of the

machine) are stored locally on the hard disk in an offsets file called local.lpf. For

each product file, any offset values required are stored added to the offsets file.

The addition to the offsets file is made when the first board is run and only if

Custom is selected.

Because the product file is not updated other machines are able to share the

product file.

Loading a Product When a product is loaded, if Custom is selected and a corresponding entry in the

offsets file (local.lpf) exists, the parameters are read from the offsets file and

added to the corresponding parameters from the product file, the sum of the two

values for each fiducial offset is used as the new parameter. The chase offsets

are calculated for the first board and are saved to the local.lpf file.

Actuator Limits If due to the new fiducial positions the actuators are required to go close to their

limits a warning is generated. If the actuator would need to travel beyond its

limit an error is generated and the red beacon is illuminated.

Board Stop X

Offset

This parameter allows a value to input which compensate for variations in the

focal lengths of the vision systems between machines.

This parameter has no function while remote board stop is fitted.

Run on Delay This parameter sets a delay of up to one second for the print station belts to stop

once the board is detected at the camera board stop. Effectively this prevents

any board ’bounce back’ which may occur when belt speeds are high.

Parameter settings for run on delay are:

NOTE

This parameter is for the High Throughput Conveyor option only.

Remote Board Stop Sets whether the remote board stop facility is to be used, options are:

Fiducial Finder This parameter is used, while Feature Licensing asserts that use of Fiducial

Finder 2 is authorized, to specify which fiducial finder is to be used, options are:

Auto Fiducial

This parameter sets whether the facility to automatically learn fiducials is to be

used, options are:
