More Information

Overview Manuals Transducer Chain Protection Logic Commissioning Application
  • Use only for shaft-relative vibration with a compatible eddy current chain
  • Preserve both channel modes, filters, alarms and relay assignments before a swap
  • Manage protection bypasses even though the 3U card is hot-swappable

Emerson A6110 is a two-channel AMS 6500 protection monitor for shaft vibration measured relative to the bearing housing.

It accepts supported PR642x eddy current measuring chains, processes channels independently or in combined modes, and provides alarm, buffered and proportional outputs in one 3U rack slot.

Before replacement or commissioning, preserve the channel mode, sensor and converter types, gap and scale, filter settings, alarm and trip logic, relay assignments, bypass state and rack configuration.

Availability, condition, price, and shipping time for A6110 are confirmed during quotation.

  • Match each PR642x probe to its documented CON converter
  • Verify sensor gap and bias before comparing vibration
  • Confirm channel polarity and units from the saved configuration
  • Retain Alert and Danger setpoints and delay behavior
  • Preserve relay voting, limit multiply and trip-bypass assignments
  • Document every active bypass before and after maintenance
  • Check front and rear buffered signals
  • Verify 0/4 to 20 mA and 0 to 10 V assignments
  • Perform controlled alarm-path checks before returning protection to service
  • Relative shaft vibration protection on steam, gas and hydro turbines
  • Sleeve-bearing compressor shaft-vibration monitoring
  • Critical rotating-machine protection integrated into an AMS 6500 rack
Description

A6110 is an Emerson AMS 6500 dual-channel monitor for shaft-relative vibration protection using compatible eddy current measuring chains.

It supports independent and combined channel modes, configurable filters, alarms, relay logic, buffered outputs and proportional outputs in one 3U rack slot.

Before replacement, record probe bias, converter identity, channel polarity, scale, filter settings, alarm and trip logic, relay assignments, bypass state and rack configuration.

Technical notes
A6110 measures shaft motion relative to the probe mounting. Do not treat it as an absolute casing-vibration monitor; confirm the complete eddy current chain and saved AMS 6500 configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should Emerson A6110 be used instead of a casing-vibration monitor?
Use it when the required protection variable is shaft motion relative to the bearing housing, especially on sleeve-bearing machinery; casing vibration is a different measurement.
Can Emerson A6110 accept an arbitrary proximity probe?
No. Confirm a supported PR6422, PR6423, PR6424 or PR6425 sensor and the documented CON011/91, CON021/91 or CON041/91 measuring chain.
What must be preserved when replacing an Emerson A6110 card?
Save both channel modes, ranges, filters, alarm and danger setpoints, voting or relay logic, current-output assignments, bypass state and the exact slot configuration.
Can the two channels on Emerson A6110 be configured differently?
The monitor supports independent or combined monitoring modes, but the selected mode, transducer chain and machine protection strategy must be recreated exactly.
Why can Emerson A6110 show high vibration immediately after a card replacement?
Check probe bias and gap, converter pairing, channel polarity, scale, filter range, monitor units, grounding and whether the channel was restored in the correct independent or combined mode.
Is hot swapping Emerson A6110 risk-free?
No. Although the module is hot-swappable, machine protection, relay voting, bypass authorization and channel outputs must be managed according to the site procedure before removal.
What acceptance checks matter after installing Emerson A6110?
Verify each bias voltage and buffered signal, simulate or safely compare known vibration, confirm current and voltage outputs, exercise Alert and Danger paths, and document restoration of every bypass.
