4. Installation & Wiring Operating Instructions

4.1 Installation Steps

1. Cut off the power supply of the target control rack backplane before installation and maintenance;

2. Align the golden finger connector of P0916TQ with the reserved FCM slot of the main controller rack, push horizontally until the side lock buckle clicks to lock tightly;

3. Fix the side fixing buckle to prevent module loosening caused by cabinet long-term vibration;

4. Insert one end of single-mode ST fiber jumper into the optical port of P0916TQ, and connect the other end to the fiber communication module of remote FBM rack;

5. Arrange optical cables separately from strong current power cables, fix cable ties to avoid excessive bending of optical fiber (minimum bending radius ≥30mm);

6. Restore cabinet redundant power supply, observe RUN and LINK indicators to confirm normal optical communication connection.

4.2 Wiring & Optical Cable Requirements

• Must use industrial single-mode optical fiber jumpers with ST connectors, multi-mode fiber cannot reach 10km transmission distance;

• Optical fiber shall not be twisted, squeezed or bent sharply to prevent fiber core breakage and signal interruption;

• Separate optical cable routing and high-current power wiring, maintain spacing above 15cm to avoid mechanical extrusion;

• Do not touch the end face of the optical fiber connector with bare hands, use special alcohol cotton to clean dust before plugging;

• All wiring and optical cable laying must comply with local industrial electrical safety codes.

5. Commissioning & Daily Operation Guide

1. After power-on, the green RUN light keeps steady on, indicating the module obtains normal backplane power supply;

2. The green LINK light lights up to represent normal optical signal handshake between local and remote fiber modules;

3. TX/RX indicator flashes synchronously, proving bidirectional fieldbus data transmission is normal;

4. If red FAULT light flashes continuously, cut off power supply first to check optical fiber breakage, loose optical port or remote module power failure;

5. Complete remote I/O rack address matching and bus communication configuration through I/A Series engineering software;

6. Perform 72-hour continuous communication test after commissioning to confirm no intermittent signal disconnection or communication loss.

6. Routine Maintenance & Troubleshooting Guide

6.1 Regular Daily Maintenance

• Clean dust on module front panel and optical port with dry dust-free cloth every 3 months;

• Inspect optical cable bending state and connector locking tightness monthly;

• Do not install P0916TQ close to heat sources such as power modules and transformers in the cabinet.

6.2 Common Fault Diagnosis & Solutions

1. Module RUN light off: Check rack 24VDC redundant power circuit, confirm backplane power output is normal;

2. LINK light off with RUN light normal: Pull out and reinsert optical jumper, clean optical port end face, replace broken optical fiber;

3. FAULT light flashing frequently: Check whether remote FCM module loses power, eliminate ground loop potential difference fault;

4. Intermittent communication dropout: Increase optical cable bending radius, avoid parallel laying with high-frequency strong current cables.

7. Safety Warning Clauses

1. P0916TQ is only allowed to be installed in indoor sealed industrial control cabinets; outdoor open-air installation is prohibited;

2. All disassembly, optical cable replacement and maintenance operations must be completed by certified DCS automation engineers with power isolation measures;

3. Unauthorized disassembly of the module shell is forbidden; internal circuit damage caused by private disassembly is not covered by official warranty;

4. Avoid direct eye contact with the optical port transmitting laser to prevent permanent eye damage;

5. Discard waste communication modules in accordance with local electronic waste recycling regulations, random disposal is prohibited.
