Theory of Operation

The Single-Axis Automatic Tilt Mechanism can tilt the dispensing valve in one of the following positions:
• Vertical
• Counterclockwise (CCW)
• Clockwise (CW)
The tilt angle can be adjusted 10, 20 or 30 degrees.
The tilt bracket can be mounted in two ways:
• Front and rear tilt
• Right and left tilt
The tilt bracket is driven by a three position air cylinder, where the top port controls whether a center stop
is enabled or not. In order for the cylinder to reach the center position, the top and bottom ports must be
energized at the same time. To create the proper center holding force, the air pressure on the top port
must be about twice as much as the pressure on the bottom port. To create this pressure difference,
there is a small regulator mounted on the left side of the bulkhead. This regulator should be set to 40 psi.
The angle of tilt is determined by where the stops are located. After the tilt system has been set up, the
user is able to select a tilt direction in the Fluidmove software. After setting a tilt angle instruction in
Fluidmove, all subsequent instructions are performed at the specified tilt until a new tilt instruction is
added. See
