Pneumatic Supply The pneumatic air supply offers a positive force to the ProFlow system during
the print cycle providing a continuous supply of print material to the stencil.
NOTE
This force should not be confused with system pressure which is the force
applied to the ProFlow unit by the printhead mechanism stepper motor.
Software Control System air pressure is applied to the piston crosshead enabling the pressure
actuators. ProFlow pressure is factory set at 2.0 bar, however this can be
adjusted under edit data.
The Idle Paste Pressure parameter applies a light pressure onto the piston
crosshead and print material system whilst the ProFlow unit is idle, but remain-
ing on the stencil surface. (Refer to Adjustments and Settings - Software
Pressure Adjustment Section of this chapter for further details.)
An SMC SCAR is used on GSX and Lt machines and a Norgren SCAR on all
other machines.

ELECTRICAL DETAIL
For electrical detail on Infinity, Horizon and ELA machines refer to the
respective Technical Reference manual. For GSX and Lt machines only, a
PCADADIO card is used. The PCADADIO card is a multi-purpose I/O board
with the following functions:
• 8 Differential Multiplexed Analogue Inputs.
• Two Analogue Outputs.
• 16 Digital I/Os.
• 3 Counter-timer Channels.
The operation of these functions are controlled using the PC XT bus and link
options.
