Surround plate setup
Note
setup, soft lift land and pitch adjustment checks must have been completed
before this stage.
• If not already done loosen all fasteners that hold the top and bottom surround plate to the
bearings. (Screw Thread engagement still needed but both plates must be free to move)
• With the TRP in home position and table at transport height
• Load a tray with substrates
• Drive TRP over rails
• Apply TRP pressure
• Toggle vacuum on
• Drive table to Vision height
• Check that the four TRP height adjustment screws are not in contact with the rail cap and
that the TRP is flat against the surround.
• Toggle on the Z lock
• Toggle on the active surround
• Drive TRP to home position
• All substrates should be sat within the surround and surround referencing the substrates into
the top left corner of the top surround plate.
• Using your finger check for movement in all substrates in X and Y direction.
• If any movement is found manual adjustment is needed to the position of the top surround plate.
• After observing the movement in the substrates determine the movement needed in the
to apply equal pressure to the side walls of each substrate in each position.
• With one hand manually apply pressure to the top surround plate moving it in the direction desir
e
• With you other hand check for movement across all substrates and continue to apply
pressure until movement has been removed.
• Visually check that no gaps can be observed between the substrates sidewalls and surround
plates top and bottom
• Whilst still applying force to the top surround plate; In a circular motion tighten all surround
plate screws, this doesn’t need to be over tightened and should be equal to 1.8Nm
