-
Control Tuning: Tune active control algorithms during commissioning.
-
Dynamic Analysis Baseline: Review baseline FFT and transfer functions.
-
Adaptive Filter Testing: Verify filter performance with known inputs.
-
LED Diagnostics: Green = normal; Amber = fault; Red = module fault.
-
Fault Log: Access 750-event log via Toolbox ST—review vibration snapshots.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware Updates: Ensure the GE IS215UCVDH1A is in “standby” mode.
-
ESD: Handle by edges with grounded wrist strap.
