INNPM22 ABB IN STOCK

‌ABB INNPM22 Operational Workflow‌

‌1. Pre-Startup Checks‌

• Verify power supply: ‌24V DC ±10%‌ (label: TB1 terminals 1/2).
• Inspect field wiring for ‌shielded twisted-pair cables‌ (max. length: 500m).
• Confirm ‌DIP switch settings‌ (SW1) match network protocol (e.g., Modbus RTU: SW1.1=ON).

‌2. Configuration‌

• Use ABB Automation Builder (v3.1+) to:
  • Set ‌node address‌ (range: 1–247 for Modbus).
  • Assign ‌I/O mapping‌ (default: 4–20mA inputs = registers 40001–40008).
  • Enable ‌diagnostic alarms‌ (e.g., over-range = register 40100).

‌3. Calibration‌

• Zero adjustment: Short-circuit inputs → Trigger ‌CAL0‌ command (register 40200).
• Span calibration: Apply ‌20mA reference‌ → Trigger ‌CAL20‌ command (register 40201).

‌4. Diagnostics‌

• LED indicators:
  • ‌PWR (Green)‌: Steady = Normal.
  • ‌COM (Yellow)‌: Blinking = Data traffic.
  • ‌ERR (Red)‌: Fault (check register 40100).

‌5. Maintenance‌

• Quarterly: Clean ventilation slots (compressed air, ≤0.3MPa).
• Annually: Verify calibration drift (<±0.1% FS).

‌Troubleshooting‌

• ‌No communication‌: Check termination resistors (120Ω for RS-485).
• ‌Invalid data‌: Reinitialize I/O mapping in software.
