6. Installation Notes & Maintenance Best Practices
   Pre-installation considerations
   Ensure proper backplane seating and confirm channel allocation matches the control strategy. Verify load impedance and wiring for each channel to avoid excessive load or crosstalk. Plan cabling routes to minimize EMI, keeping power and signal lines separated where possible. Validate the calibration procedure in GE’s documentation and align with the controller’s firmware baseline to prevent drift or mismatch.

Maintenance best practices
Schedule periodic calibration checks for each channel to maintain accuracy, and monitor channel health via the GE diagnostics tools. Check for signs of thermal stress or connector looseness during inspections. Keep firmware and configuration backups and ensure spare ALG392 units are available for fast field replacements. Document calibration data, channel-by-channel performance, and any load changes in the asset management system for audits and upgrades.
