Signal paths support integration-based velocity derivation, 1X synchronous tracking for rotational harmonics, and band-pass filtering for broadband excitation components. Each channel pair can be bound to independent Keyphasor references, enabling phase-resolved vibration vector calculation under variable turbine speed profiles.\u003c\/p\u003e\n\u003cp\u003eAlarm logic supports up to 8 configurable threshold sets per channel pair, allowing condition-specific switching between operational states without hardware reconfiguration.

Route low-level vibration signals away from power conductors and switching devices to reduce electromagnetic coupling. Cable shields must be grounded at a single rack-end point.\u003c\/p\u003e\n\u003cp\u003eDuring commissioning, verify correct sensor type assignment and filter configuration before enabling alarm logic.
