Maintenance

  • Routine inspection: Check module LED status, backplane connector and redundancy sync cable condition every 6–12 months
  • Clean module surface with dry compressed air; liquid solvent cleaning is strictly prohibited
  • ESD protection must be adopted during disassembly, anti-static wristband required
  • If redundancy switchover alarm triggers, check sync cable, Ethernet connection and CPU health status
  • 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 redundant processor kit

 

Installation

  1. Follow DCS safety operation procedure; hot-swap replacement can be executed under safe operating condition or cut off cabinet power supply.
  2. Wear anti-static wristband to prevent electrostatic damage to PCB components.
  3. Install TP830 baseplates on rack slots, insert two PM864A processor modules and lock fastening latches.
  4. Connect redundancy synchronization cable between the two CPUs.
  5. Connect shielded Ethernet cables to onboard RJ45 ports for control network.
  6. Configure controller parameters, redundancy settings and download control program via engineering software.
  7. Restore power supply, verify CPU synchronization and redundant switchover status.
  8. Perform loop test and commissioning; validate bumpless failover function between primary and standby CPU.
