6. Installation Instructions

1. Power Off: Disconnect power to the Momentum I/O base.

2. ESD Protection: Use anti‑static wristband when handling.

3. Mounting: Align adapter with I/O base connector; press firmly until seated. Tighten screws.

4. RS‑232 Wiring: Connect DB9 cable to HMI/SCADA; configure baud rate, data bits, parity, stop bits.

5. Power Up: Apply 5 V DC. Check LEDs: PWR ON, RUN blinking (program execution), COMM blinking (activity).

6. Programming: Download LL984 program via Concept, ProWORX 32, or Modsoft.

7. Compatibility

• I/O Bases: All 170XTS series Momentum discrete/analog I/O bases

• Network: Modbus RTU/ASCII (RS‑232 slave only)

• Replacement: Superseded by 171CCS76000 (RS‑485) or 171CCC96030 (Ethernet + RS‑485)

8. Safety & Handling

• Installation/maintenance by qualified personnel per local codes.

• Disconnect power before wiring/service to avoid electric shock.

• Avoid water, moisture, corrosive substances, direct sunlight.

• Use ESD protection to prevent static damage.

• Do not open casing; no user‑serviceable parts inside.

9. Maintenance & Troubleshooting

• Inspection: Quarterly check for cracks, loose screws, damaged connectors, LED status.

• Cleaning: Dry, lint‑free cloth only; no solvents/abrasives.

• Common Issues:

  • PWR Off: Check 5 V DC supply from I/O base.

  • FLT On: CPU fault; re‑seat adapter, reload program, check I/O base.

  • COMM No Response: Verify RS‑232 wiring, baud rate, parity, slave address.

  • No Program Execution: Ensure program downloaded, RUN mode active, no fatal faults.
