Fast/Normal Mode For a conveyor to operate in fast transfer mode, both Fast Transfers Disabled
buttons must be OFF (LED extinguished). The LCD screen on the PLC displays
‘Fst.Trans.’ on the bottom line for 5 seconds on power up or when the button is
switched to OFF.
For a conveyor to operate in normal transfer mode, both Fast Transfers Disabled
buttons must be ON (LED lit). Normal transfer mode is not displayed on the
PLC.

Board Clamps A board clamping arrangement is utilized to secure the board during the print
process and to minimize board distortion. A pneumatically operated piston, (via
a 24V switched solenoid 16SOL10 from the machine controller), lowers the
board clamp and foil, trapping the board on the transport belts. On completion
of the print stroke the board is released by activation of the pneumatic solenoid.
An in-line pneumatic exhaust ensures quick release of the board clamps.

to the board edge.
The adjustable snugger plate, rear rail guide and fixed snugger plates are
interchangeable with similar units to facilitate differences in board thickness.
This system caters for 0.8mm, 1.0mm and 1.6mm board thickness.
To clamp the board in position for the printing process, the board is gripped
between the fixed and adjustable snugger plates by action of the pneumatically
operated piston. Pneumatic operation utilizes the existing board clamp circuit,
(via a 24V switched solenoid 16SOL10 from the machine controller).
On completion of the print stroke the pneumatic solenoid is de-activated allow-
ing the actuator pistons (sprung loaded), to retract the adjustable snugger plate
away from the board.

Foil-less Clamps This option is used on thin boards which are populated with components too
close to the edge of the board for traditional board clamps. The board is secured
during the print stroke by the use of vacuum. The clamps are perpendicular to
the board maintaining a good gasket between the board and the stencil. The
