Pneumatic Diagrams

Air circuit and valve manifold references for service and troubleshooting.

1. Scope

Use this section to locate pneumatic diagrams, valve manifold layouts, and air circuit references.

⚠ WARNING Isolate and vent the air supply before disconnecting tubing or working on actuators. Stored energy can remain in cylinders and tooling.

2. Air preparation and isolation (typical)

Most i5 machines follow this chain:

1. Air inlet and isolation valve.

2. Filter / regulator (and gauge).

3. Soft-start and dump (safety) valve.

4. Distribution to valve manifolds and point-of-use regulators.

Confirm supply pressure and flow before troubleshooting valves or cylinders.

3. Valve manifolds

The machine typically uses one or more valve manifolds.

For each manifold, document:

• Location on the machine.

• Manifold ID and valve/coil numbering.

• Coil voltage.

• Manual override method.

Match PLC outputs to:

• Solenoid coil ID.

• Valve position (NC/NO where applicable).

• Actuator function.

4. Air circuits (examples)

Depending on machine build, circuits may include:

• Tool clamp / tool lift.

• Sealing head lift and dwell functions.

• Conveyor stops and product handling.

• Film brake / film clamp (where fitted).

• Blow-off and purge air.

• Gas flush enable/actuation (where fitted).

5. Diagram set (attach or link)

Attach or link the latest approved pneumatic documentation set:

• Pneumatic schematic (full circuit).

• Manifold layout(s) with valve numbering.

• Tubing schedule / from-to list (if available).

• Point-of-use regulator settings (if specified).

If you are storing diagrams in the manual downloads area, keep a link to the latest approved set:

6. Pneumatic troubleshooting pointers

• If multiple functions fail, suspect supply air, dump valve state, or manifold power.

• If one function fails, check the solenoid command, then the valve, then the cylinder.

• If motion is slow, check exhaust restrictions, silencers, and regulator settings.
