ADJUSTING THE SOFT TOUCH VALVE SYSTEM
Set the CLOSE pressure regulator inside the enclosure so that the CLOSE
1.
PRESSURE gauge on the door is at approximately 3psi.
Set the OPEN pressure regulator inside the enclosure so that the OPEN PRESSURE
2.
gauge on the door is at approximately 12 psi.
3.
Turn the TEST switch TO TEST CLOSE. The riveting mandrel should close. If it
doesn't, increase the CLOSE pressure regulator. Check the force between the
riveting mandrel and decrease this pressure slightly if the force is great enough to
crush a wood pencil more than 1/16" in depth.
4.
Adjust the OPEN pressure regulator so that when the TEST switch is turned to
TEST OPEN, the riveting mandrel open smoothly. Use the lowest setting on this
OPEN pressure regulator that will smoothly open the riveting mandrel. This will
produce the fastest mandrel closing time.
