3. ⚙️ Installation & Maintenance
Installation Guidelines
- Mount the unit on a flat, vibration-free surface using appropriate screws.
- Ensure proper grounding of the chassis to avoid electrical interference.
- Route input and output cables separately from high-power lines to minimize noise.
- Use the recommended wire gauge for all relay outputs to prevent overheating.
- Verify that the supply voltage matches the nominal requirement before powering the unit.
Maintenance Tips
- 🔄 Periodic Inspection: Check terminals for looseness, corrosion, or damage every 6 months.
- 🧹 Cleaning: Keep the unit free from dust and debris; use dry compressed air only.
- 🔋 Voltage Monitoring: Ensure stable supply voltage to prevent relay chatter or failure.
- 🔧 Relay Replacement: Use original WOODWARD relay parts for consistent performance.
- 📝 Log Checks: Record any unusual relay operations to diagnose potential issues early.
