Check Air Pressure Supply

Verify main air pressure is 80-100 PSI at the machine inlet. Check pressure gauge on pneumatic panel.

Ensure machine is in EMERGENCY STOP before checking pneumatic connections.

Inspect Pneumatic Cylinder

Visually inspect parts catcher cylinder for air leaks, damaged seals, or bent rod. Listen for air leaks during operation.

Spray soapy water on fittings to identify small air leaks.

Test Manual Operation

Use MDI mode to manually command parts catcher movement with M-codes to isolate cylinder operation from control logic.

Check parameter 310 (Parts Catcher Enable) is set to 1 before testing.

Replace Pneumatic Components

Replace faulty cylinder, air lines, or solenoid valve if leaks or mechanical damage are found.

Lock out air supply and depressurize system before component replacement.

Check Sensor LED Indicators

Observe proximity sensor LED status while manually moving parts catcher. LED should change state when target approaches.

Most Haas proximity sensors have built-in LED indicators for quick diagnosis.

Clean Sensor Face

Clean proximity sensor face with compressed air and lint-free cloth to remove metal chips, coolant residue, or debris.

Do not use harsh solvents that may damage sensor housing.

Verify Sensor Gap

Check sensor-to-target gap is within specification (typically 2-4mm for inductive sensors). Adjust mounting bracket if necessary.

Use feeler gauges to set precise sensor gap for consistent operation.

Test Sensor Signal

Monitor sensor input signal in CURRENT COMMANDS > INPUTS screen while triggering sensor manually.

Document input bit number for future reference during troubleshooting.

Visual Inspection for Obstructions

Open machine doors and inspect parts catcher area for jammed parts, tangled chips, or foreign objects blocking movement.

Ensure spindle is stopped and machine is in EMERGENCY STOP before reaching into work area.

Clear Physical Blockages

Remove any parts, chips, or debris blocking catcher movement. Use appropriate tools to avoid damaging mechanism.

Keep a dedicated set of non-marring tools for clearing delicate mechanisms.

Check Catcher Alignment

Verify parts catcher is properly aligned and not binding on guide rails or mounting hardware.

Apply light machine oil to guide rails if binding is detected.

Test Full Range of Motion

Manually cycle parts catcher through full range of motion to ensure smooth operation before returning to automatic mode.

Keep hands clear of pinch points during manual testing.

Check Parameter 310

Navigate to SETTING > PARAMETERS and verify Parameter 310 (Parts Catcher Enable) is set to 1 for enabled operation.

Parameter changes require EMERGENCY STOP cycle to take effect.

Verify Timeout Parameters

Check parts catcher timeout parameters to ensure adequate time is allowed for mechanism operation.

Increase timeout values if catcher operates slowly due to low air pressure.

Reset Parameters to Default

If parameters appear corrupted, restore parts catcher related parameters to factory defaults and reconfigure as needed.

Document current parameter values before resetting to defaults.

Inspect Electrical Connections

Check all electrical connections to parts catcher solenoid and sensors for looseness, corrosion, or damage.

Disconnect power and lock out electrical panel before inspecting connections.

Test Continuity

Use multimeter to verify continuity from control cabinet to parts catcher components through wire harnesses.

Check continuity with connectors both connected and disconnected to isolate connection issues.

Clean and Secure Connections

Clean corroded connections with electrical contact cleaner and ensure all connections are properly tightened.

Apply dielectric grease to outdoor or high-moisture connections for long-term reliability.
