INNPM22 ABB Module

1. Pre-Operation Preparation

1.1 Safety Verification

• Confirm power supply disconnection before installation
• Verify grounding resistance ≤4Ω using a megohmmeter
• Check ambient temperature (-20°C to +60℃) and humidity (<85% RH) compliance

1.2 Hardware Configuration

• Signal Wiring:

  Analog Input: 4-20mA (max 250Ω load) / 0-10V (impedance ≥1MΩ) Digital Interface: RS-485 terminals (A+/B-) for Modbus RTU

• DIP Switch Settings:
  • SW1: HART protocol enable/disable
  • SW2: Channel isolation mode (single/dual)

2. Commissioning Procedure

2.1 Power-Up Sequence

1. Apply 24V DC power (18-36V range)
2. Observe STATUS LED:
   • Solid green: Normal operation
   • Flashing red: Configuration error

2.2 Software Configuration

• Parameter Initialization:

  a. Connect to ABB Control Builder via USB/RS-485 b. Import device description file (DDF) for HART/Modbus mapping c. Set scaling coefficients (e.g., 4mA=0%, 20mA=100%)

• Diagnostic Test:
  • Force input range violation to trigger alarm relay (NC→NO transition)

3. Runtime Monitoring

3.1 Signal Validation

• Use multimeter to verify output deviation ≤±0.1% FS
• Monitor communication errors via Modbus exception codes (e.g., 0x04 = input failure)

3.2 Maintenance Actions
