Trang 2The rising table moves up and down within the machine supporting the product board, via the tooling, and accurately positions the height of the rails at several different pre-determined heights during the print cycle The rising table contains the attachment points for the transport rails and the drive for the moving rear rail, for more information refer to the Transport Rails chapter.
The rising table heights, determined by the software and referenced from the home position, are as follows:
• Home Position
• Transport Height
• Vision Height
• Print HeightThe rising table homes only when the machine initialises, this is achieved at power up or when exiting diagnostics Transport height is preset in the product file allowing clearance for the board to clear the tooling whilst entering and leaving the machine Vision height brings the board into the camera focal length for the vision system The board is paused at this height whilst screen alignment
is achieved The rising table is taken up to print height for the board to be printed
The rising table also supports the remote board stop which is used for ing large or heavy boards
position-NOTE
1 Currently, there are two types of standard transport rail system: The Rail System (RS) and the Modular Transport Rail (MTR) The rising table home vanes are set at different heights for both types.
2 The Rapid Throughput Conveyor (RTC) printer option has its rising table home height 10mm lower than that of a standard printer.
Trang 4ADJUSTMENTS AND SETTINGS
Rail to Table Height
Two rail systems are available: The Modular Transport Rails (MTR) and the standard Rail System (RS) The rail to table height settings differ for both types.Refer to the Transport Rails or High Throughput Conveyors (HTC) chapters for the rail to table height

Configuring the
Remote Board
Stop
Two board stop options are available:
• Camera board stop
• Remote board stopThe camera mounted option is used to stop small, comparatively lightweight products in the correct print position where they are clamped The remote board stop is mounted on the rising table and provides a more robust unit for larger, heavier products
Configuring the remote board stop should only be carried out when called for in one of the following procedures:
Camera to Remote Board Stop - LHS ration Change from using the camera mounted board stop to the remote board stop The
Configu-remote board stop is mounted on the left side
of the rising table.
Camera to Remote Board Stop - RHS ration Change from using the camera mounted board stop to the remote board stop The
Configu-remote board stop is mounted on the right side of the rising table.
Remote Board Stop - LHS to RHS Configuration Change the remote board stop location from
the left to the right side of the rising table Remote Board Stop - RHS to LHS Configuration Change the remote board stop location from
the right to the left side of the rising table Remote Board Stop - Same side configuration Change the remote board stop position when
switching between products with different board widths.
Trang 8LHS Configuration The remote board stop is configured for the LHS when:
• The board stop rotates anti-clockwise to the raised position and faces the rear of the machine when lowered, (as shown below)
• The reed switch is positioned between the fixed stop and the adjustable stop
To achieve this carry out the following:
1 With the board stop in the position shown below, slacken the two grub
screws using a 2mm Allen key.
2 Without moving the drive shaft, rotate the rotary arm and board stop 90 degrees clockwise, so that the board stop is vertical Tighten the two grub screws
3 Using the access hole in the side of the remote board stop assembly,
Trang 9slacken the adjustable stop securing screw.
4 Rotate the reed switch and adjustable stop clockwise until the reed switch abuts the fixed stop
5 Tighten the adjustable stop securing screw through the access hole
6 Continue with the appropriate one of the following procedures:
• Camera to Remote Board Stop - LHS Configuration
• Remote Board Stop - RHS to LHS Configuration
Trang 10RHS Configuration The remote board stop is configured for the RHS when:
• The board stop rotates clockwise to the raised position and faces the rear
of the machine when lowered, as shown below
• The adjustable stop is positioned between the fixed stop and the reed switch
To achieve this carry out the following:
1 With the board stop in the position shown below, slacken the two grub
screws using a 2mm Allen key.
