14.3 TEST CYCLES
Carry out the following procedure to access the Test Cycles:
► Select Maintenance.
► Select Test Cycles.
► The following options are displayed:
●
Dry Align Test
●
Accuracy Test
●
Data Logging On/Off
14.3.1 Dry Align Test
Selecting this function initiates the machine to run Dry Alignment accuracy tests.
With data logging set to On, all test data is output to a Test.log file. With data logging set to Off, all
test data is output to a Test.dat file.
14.3.2 Accuracy Test
Selecting this function commences a series of 4 tests:
●
Operation of the vision camera
●
Movement of the camera
●
Repeatabiltiy of the rising table and rail system
●
Operation of the chase clamps.
With data logging set to On, all test data is output to an atest.dat file that can be imported into a Lo-
tus spreadsheet to assist in determining the cause of location accuracy problems associated with
camera positioning, chase clamping and table movement. Pressing the Stop Run key at any time
during the sequence of tests terminates the cycle on completion of the respective test and return to
the previous menu.
To recommence the test cycle select Accuracy Test, this starts the tests at Test 1 again and not
where the test cycle was previously terminated.
14.3.3 Data Logging On/Off
Selecting this function enables/disables data logging from within the main menu without the neces-
sity of entering the diagnostics mode.
With data logging enabled, the following data files are created on the PC hard drive giving informa-
tion on certain machine functions:
●
Camera.dat
●
Fiducial.dat
●
Inspect.dat
●
Pressure.dat
●
Ptest.dat
●
Screen.dat
14.3.3.1 Camera.dat
This file is created when cycle camera system is running in diagnostics and records fiducial loca-
tions for each camera cycle.
14.3.3.2 Fiducial.dat
This file is created at the end of the calibration function and records fiducial detection data for the
50 locations.
14.3.3.3 Inspect.dat
This file is created by SPC and records 2Di paste results in a raw data format.

14.3.3.4 Pressure.dat
This file is created in run mode and records squeegee pressures during the print stroke.
14.3.3.5 Ptest.dat
This file is created when calibrating the squeegee reference height with pressure hardware en-
abled. The file records the amount of steps the squeegee is driven down with the pressure
achieved.
14.3.3.6 Screen.dat
This file is created when cycle alignment system is running in diagnostics and records positional
deviations of the stencil fiducial.
