User Manual
Model PCS
Pneumatic Motion Control System
TYPICAL APPLICATIONS
The PCS system is ideal whenever increased flexibility and adaptability is needed in a process; for example, in
order to accommodate various size parts and assemblies, or to add control for improved consistency, quality,
and productivity. Typical applications are listed below.
Flow Gate
The PCS system can control the position of a flow gate, controlling the rate of product that flows to downstream
processes. The position of the gate can be changed to allow more or less product flow depending on the
requirements of the process. Sometimes this is controlled manually, resulting in wasted manpower and less
control.
Robotic End Effector
The PCS system can control the open position of an end effector for a robotic arm. If the robotic arm is picking
and placing differently sized products, the cycle rate can be increased if the open position is automatically
adjusted to be only slightly larger than the product itself, reducing the time it takes to grasp the product.
Exhaust Control
The PCS system can control the position of exhaust dampers used in process control systems for increased
control in plant emissions, smoke houses, and similar applications.
Labeling
The PCS system can position differently sized parts under a label applicator, allowing the labeling process to
continue without any down time for a setup change to adjust for product size.
Animatronics
The PCS system can produce lifelike movements of puppets and figures, such as those used in amusement
and entertainment industries. Using an industrial computer or PC, movements can be changed without a
hardware change, simplifying new shows and edits.
GLOSSARY OF TERMS AND FORMULAS
For clarity, please review the definitions below. Descriptions for linear motion actuators (PFCN, PFC, PFCNL,
PFCL) are often different from descriptions for rotary actuators (PTF).
ZERO (ZERO Position)
When the PFC rod is fully retracted or the PTF shaft is rotated fully counterclockwise (CCW), it will reach a
mechanical stop, due to either a mechanical limit in the application or the actuator’s end of stroke or rotation.
The PCS’ Zero adjustment allows you to adjust the position of the cylinder at 0 VDC control voltage input.
Adjustment range is from the fully retracted mechanical limit to approximately 50% of the full actuator stroke or
rotation. Refer to the installation section for a description of the adjustment procedure.
