Assembly
The assembly is fitted to the sequencer block and logic plate which is secured
to the left hand side of the central rear upright of the lower frame of the printer,
and connected to the printer air supply via the operator interface. Mounted on
this panel are the components used to control the sequence of raising FormFlex
pins and produce vacuum to the pins. This panel routes pneumatic pressure
from the operator interface to the manifold assembly.

Air Pilot Valves These devices are used to connect the vacuum ejector with the tooling modules,
applying vacuum to lower the FormFlex pins.

Vacuum Ejector This device also known as a venturi vacuum pump provides vacuum to the
FormFlex tooling system to lower the FormFlex pins during product changeover.
Pneumatic Timers These devices are used to control the sequence of raising the FormFlex pins
and control the output to the pneumatic indicator during product setup. The
timers are connected in series and four of these each control a pair of tooling
modules. Each of the timers introduce a 20 second cumulative delay in raising
the tooling pins. The fifth timer controls the visual indication to the operator that
all the FormFlex pins have risen.

Pneumatic Logic
Components
The pneumatic logic components consists:
• OR Gate
• NOT Gate
• YES Gate
These components are fitted to a base unit located above the pneumatic
sequencer and peripherals assembly on the sequencer block and logic plate.
These components produce a pneumatic hold on circuit for the operator switch
allowing the operator to release the operator switch during raising of the
FormFlex pins.
