Maintenance

  • Routine inspection: Check LED status, fiber connector cleanliness and fiber cable integrity every 6–12 months
  • Clean optical fiber end face with professional fiber cleaning tools; do not use liquid solvent
  • ESD protection must be adopted during disassembly, anti-static wristband required
  • If optical link loss occurs, inspect fiber for breakage, dirt or bending damage
  • Do not plug/unplug optical fiber while the module is powered on
  • Do not energize the module if PCB corrosion, burn marks or condensation are found
  • We support function testing, refurbishment and spare replacement service for this optical media converter

 

Installation

  1. Cut off the 24VDC power supply before operation; hot swap is not supported.
  2. Wear anti-static wristband to prevent electrostatic damage to PCB and optical components.
  3. Clip TB826 module onto 35mm DIN rail inside cabinet and lock the mounting buckle.
  4. Connect HCS versatile link fiber to the module local port; connect SC single-mode field fiber to long-distance port.
  5. Ensure fiber connectors are clean and fully inserted, avoid excessive bending radius of optical cable.
  6. Restore 24VDC power supply.
  7. Check LED status to confirm optical link establishment.
  8. Verify ModuleBus data communication between controller and remote I/O, complete commissioning.
