Emerson A6220 is a dual-channel AMS 6500 monitor for shaft eccentricity and bow during low-speed machine operation.
It accepts supported PR642x eddy-current measuring chains and provides independent channel processing, proportional outputs, buffered signals and protection alarms in one hot-swappable rack slot.
Before replacement or commissioning, preserve probe and converter identities, cold gap, slow-roll reference, channel scale and polarity, alarm logic, relay assignments, bypass state and the saved rack configuration.

A6220 is intended for dual-channel slow-roll eccentricity and shaft-bow verification during startup, shutdown and turning-gear operation.
Selection depends on the installed PR6422, PR6423, PR6424 or PR6425 probe-converter chains, their scale and polarity, and the saved alarm and relay assignments.
Before removing the card, record raw signals, gap voltage, channel settings and every active bypass.
