Maintenance

  • Routine inspection: Check PCB dust accumulation, backplane connector and LED status every 6–12 months
  • Clean board surface with dry compressed air; liquid solvent cleaning is strictly prohibited
  • ESD protection must be adopted during disassembly, anti-static wristband required
  • If excitation regulation abnormality or communication fault alarm occurs, power off and check backplane connection and bus cable
  • 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 PPC907BE processor board

 

Installation

  1. Cut off all high voltage and auxiliary power supply of excitation cabinet, confirm zero voltage before operation.
  2. Wear anti-static wristband to prevent electrostatic damage to processor and peripheral chips.
  3. Open excitation cabinet door, release the locking mechanism of old board.
  4. Pull out the Eurocard module gently, avoid scratching backplane pins.
  5. Insert new board along cabinet guide rail and lock firmly.
  6. Confirm backplane bus connection and inter-module cables are fully seated.
  7. Restore power supply, perform excitation system self-test and bus communication verification.
  8. Download excitation parameters, carry out no-load excitation test, verify AVR regulation performance and protection interlock before commissioning.
