3.6.7 Connecting the pneumatic lines
• Use blanking plugs to seal connections not required for the functional reliability of the MPA-S valve
terminal.
Position of the pneumatic ports
If the MPA-S valve terminals are equipped with flat plate silencers, the exhaust air ( 3/5)
and (82/84) will be vented through the flat plate silencers.
On the MPA-S valve terminal with exhaust plates, the pilot exhaust air is vented on at
least one supply plate via connection (82/84).
• Make sure that the proportional pressure regulator is supplied w ith a constant pressure.
A constant supply pressure is necessa ry for good control quality. To guarantee t his, each
proport io nal pressure regulator must be connected t o a separate pressure supply.
• Mount the fitting or the silencer in accordance with Tab. 3.8. Then lay the tubing lines.
