Installation & Configuration Guide
Stage 1: Pre-Installation Preparation (Approx. 15–20 minutes)
⚠️ Before replacing any vibration-related board, place the turbine control system into approved maintenance condition.
- Notify operations and turbine maintenance teams
- Transfer machine to safe shutdown state
- Isolate cabinet power supplies
- Wait minimum 5–10 minutes before handling electronics
Required tools:
- Anti-static wrist strap
- Fluke 115 multimeter
- Terminal screwdriver set
- Label markers
- Engineering laptop with Mark VI diagnostic tools
Backup recommendations:
- Photograph terminal wiring layout
- Record cable labels and terminal positions
- Save current alarm and vibration trend data
- Verify cabinet grounding condition
One thing experienced turbine technicians always do:
Take close-up photos of terminal wiring before disconnecting anything. Vibration channels can become confusing surprisingly fast during reassembly.
Stage 2: Removal of Existing Module (Approx. 10 minutes)
- Confirm cabinet power isolation
- Label all field vibration cables
- Disconnect terminal wiring carefully
- Remove mounting hardware
- Extract terminal board slowly from rack position
⚠️ Important:
Do not pull signal wiring aggressively. Vibration monitoring cables are sensitive to shielding and grounding integrity.
