5. INSTALLATION INSTRUCTIONS

1. Power OFF (Recommended): Switch off CNC and I/O rack power.

2. Rack Slot: Insert module into empty ABU10A/ABU05A slot.

3. Secure Module: Tighten front panel screws (2×M3, 0.8–1.0 N·m).

4. Field Wiring:

   • Connect 24 VDC common to pin 1 (positive) and pin 50 (negative).

   • Wire input signals to pins 2–33 (32 points).

   • Use shielded cable; ground shield at one end only.

5. Power ON: Restore I/O rack and CNC power.

6. Configuration:

   • Set CNC parameter for I/O rack address (e.g., X0–X31).

   • Enable input monitoring in CNC diagnostic screen.

7. Test: Activate each input; verify corresponding LED and CNC status.

6. MAINTENANCE & TROUBLESHOOTING

Maintenance

• Monthly: Check LED indicators; clean front panel.

• Quarterly: Inspect wiring terminals for tightness; check for corrosion.

• Annual: Verify input response time via CNC diagnostics.

Common Issues

• No input response:

  • Check 24 VDC supply (±10%).

  • Verify wiring (common and signal pins).

  • Check for broken wire or faulty sensor.

• False triggering:

  • Improve cable shielding; separate from power cables.

  • Check for ground loops; ensure single‑point grounding.

• LED on but CNC no input:

  • Check CNC parameter settings (I/O address mapping).

  • Verify module seating in rack; re‑seat if needed.
