Installation & Wiring

1. Power Off: De‑energize the rack before insertion/removal.

2. Rack Installation: Insert into a standard TDC3000 I/O slot and secure.

3. Signal Wiring: Use shielded twisted‑pair cables; separate from high‑voltage lines.

4. Grounding: Single‑point grounding to avoid ground loops.

5. ESD Protection: Wear anti‑static wristbands during handling.

Indicator Description

• PWR (Green, steady): Power supply normal.

• RUN (Green, flashing): Module communicating and operating normally.

• FLT (Red, on): Module fault, communication loss or drive error.

Maintenance Requirements

• Periodic Inspection: Check connections and terminals for looseness or corrosion.

• Cleaning: Wipe surface dust with a dry soft cloth; avoid liquid cleaners.

• Replacement: Use only original Honeywell parts; do not disassemble the board.

• Fault Handling: Address red FLT alarms promptly to avoid process impact.

Safety Notice

• All wiring and maintenance must be performed with power disconnected.

• Do not exceed rated voltage, current, or temperature limits.

• Unauthorized modification or disassembly is prohibited.

• Comply with site safety rules and ESD procedures.
