f. Move the test board to create a small leak and ensure the sensor switches and the output
changes (NODE2 GROUP 0 ) to detect the leak. This is to replicate displaced or poorly located
substrates on the tooling.
g. Repeat this test 5 times once you have set the sensor.
h. If switch “chattering” occurs during operation increase the hysteresis setting to further separate
the OFF and ON settings.
i. Initialise the machine and load a screen.
j. Cycle the machine and deliberately cause a leak by not covering the vacuum tube. The
machine will stop and display an error message on the screen.
k. Cover the end of the pipe and press retry, the machine should carry on with the cycle.

3. VACUUM SENSE TESTING (V10 SOFTWARE)
a. In machine Software select – Maintenance – Machine set up - Vacuum Tooling Sensor
b. Select Fitted and Accept
c. In Diagnostics, select Rising Table - Sensors Tab.
d. Select Vac Tooling On button to confirm correct operation.
e. Block the end of the vacuum pipe with the Alignment test board and activate the vacuum unit.
f. Turn the pressure-setting trimmer (SET) clockwise to its limit, and then turn anti-clockwise until
the switch changes from OFF to ON (LED indicator lights).
g. Move the test board to create a small leak and ensure the sensor switches and the output
changes to detect the leak (Green circle to Red circle). This is to replicate displaced or poorly
located substrates on the tooling.
h. Repeat this test 5 times once you have set the sensor.
i. If switch “chattering” occurs during operation increase the hysteresis setting to further separate
the OFF and ON settings.
j. Cycle the machine and deliberately cause a leak by not covering the vacuum tube. The
machine will stop and display an error message on the screen
