What causes Haas alarm 113?

Shuttle in position limit switch or proximity sensor failure or misalignment preventing proper signal to MOCON. Obstruction or mechanical binding in the shuttle travel path preventing full inward movement. Hydraulic or pneumatic pressure loss in the shuttle actuation system causing incomplete stroke. Damaged or disconnected wiring between shuttle position sensors and MOCON input module. Faulty shuttle motor, solenoid valve, or actuator preventing movement initiation or completion.

How do I fix Haas alarm 113?

1. Step 1: Inspect the shuttle area for any obvious obstructions, fixtures, or chips blocking the inward travel path and clear if found 2. Step 2: Check the Diagnostics page for shuttle in limit switch or sensor input status and manually verify sensor activation when shuttle is in position 3. Step 3: Verify hydraulic or pneumatic pressure at the shuttle actuator meets specifications in the service manual (typically 60-90 PSI air or proper hydraulic pressure) 4. Step 4: Manually jog or initiate shuttle movement and observe for binding, unusual noises, or incomplete travel indicating mechanical issues 5. Step 5: Inspect all wiring and connectors between the shuttle position sensors and the MOCON board for damage, loose pins, or corrosion 6. Step 6: If all mechanical and sensor checks pass, test the shuttle solenoid valve or motor directly and replace if faulty, then verify MOCON outputs are commanding the shuttle properly

Haas Alarm 113 - Tool Changer Shuttle In Position Fault

I am not certain what Haas NGC alarm 113 specifically means. There appears to be a discrepancy between the alarm name 'Door Interlock' and the description provided about turret unlock mechanisms and shuttle positioning systems. Without definitive knowledge of what triggers this specific alarm code on Haas NGC controllers, I cannot provide accurate diagnostic guidance.

Haas Alarm 113 - Tool Changer Shuttle In Position Fault

Shuttle In Fault

This alarm occurs on Haas machines equipped with an automatic pallet shuttle system when the shuttle fails to move to the in position within the allotted time period. The MOCON board monitors inputs from limit switches and proximity sensors on the shuttle mechanism to verify positioning. The alarm prevents machine operation until the shuttle successfully completes its inward movement and the position is confirmed by sensor feedback.
