Emerson A6110 Dual Channel Shaft Vibration Monitor

Emerson A6110 Dual Channel Shaft Vibration Monitor

Basic Overview

The A6110 dual channel shaft vibration monitor is a module of the A6000 machine monitoring system, controlled by a microprocessor and used in conjunction with two eddy current measurement chains to measure and monitor the relative shaft vibration of various turbines, compressors, fans, gearboxes, and other equipment. Its two channels can be configured to be used as independent channels or interrelated, with multiple operating modes, and characteristic values can be output through the 0/4... 20mA current of each channel.

CSA certification related

Certification Mark: In order for CSA certification to be valid, all devices (IMR 6000/xx and A6000 modules) must be labeled with the corresponding CSA label. Without a label, they will not be certified by CSA.

Acceptance criteria: 24V safe low voltage SELV LPS (C22.2 60950-1) power supply is required, and the voltage comes from an independent power source; The IMR system should be placed in a suitable fire-resistant enclosure; The working environment temperature is between 0 ° C and 45 ° C, and sufficient ventilation space should be provided. If the rack environment temperature exceeds 45 ° C, cooling measures should be taken; When stacking multiple IMR units, a cooling fan bracket needs to be installed in the middle.

Installation related

Installation requirements: According to the IEC 61010 directive, fixed installation systems must be equipped with a power disconnect device, which should be easy for users to operate and labeled.

Installation and assembly: It needs to be installed in a 3U slot or other Intermas compatible housing in a 19 inch rack, and the slot should be equipped with a 48 pin plug connector (DIN 41612, design F 48 M). Before installation, check the slot wiring, push the monitor into the slot and gently press in the plug connector, then tighten the two fixing screws on the front panel.

Jumper setting: The operation of the RS 485 bus requires the installation of electrical terminators on the first and last bus devices, which are achieved through plug-in jumpers on the controller board; The raw signal of the sensor can be switched to the corresponding terminal of the connecting strip through J2 jumper, and the controller board needs to be removed when switching.

Technical parameters

signal conditioning

Two independent signal inputs, with differential voltage amplification input, resistant to open and short circuits.

Sensor signal output, dynamic output, and scaled DC output each have their own nominal range, measurement range, accuracy, frequency range, and other parameters.

The characteristic values form a dependency configuration, with multiple operating modes and corresponding parameters for current output and signal output.

Channel monitoring: continuously monitors sensor signals, system voltage, microprocessor functions, etc. The channel status has three types: normal, error, and release delay. It is displayed through the green LED on the front panel, and also has channel clearing output and external disabled input.

Limit formation and alarm: There are two alarm channels, each with an alarm output ALERT and DANGER, which can be individually set with limit values. There are alarm delay and alarm blocking functions, and the alarm status is displayed through a red LED. The alarm output is the collector/emitter segment isolated by optocouplers.

Communication interface: includes RS 232 interface (for connecting laptops/computers for configuration and visualization) and RS 485 interface (for communicating with MMS 68xx epro analysis and diagnostic system and configuration software).

Power supply: Two redundant diodes decoupled input, nominal+24V, with allowable voltage range and power consumption requirements. The sensor power supply is separated from the power supply voltage, and has corresponding parameters such as voltage, ripple, and current.

Environmental conditions: There are clear regulations on application category, environmental temperature, storage and transportation temperature, working altitude, vibration, impact, shell protection level, electromagnetic compatibility, allowable pollution level, and usage environment.

Mechanical structure: The PCB is in European standard format, with specific parameters for width, plug connectors, front panel components (LED, SMB socket connectors, mini DIN circular socket connectors), and weight.

Other information

Repair and maintenance: No maintenance is required during operation, and repair or calibration can only be carried out by Emerson. For repairs, relevant guidelines must be followed, RMA numbers must be obtained, and necessary information must be provided.

Version revision: A PI revision list is provided, which records the dates, changes, and chapters of different versions.

CE Conformity Declaration: Declare that the product complies with relevant EU directives and standards. Modifying the product without explicit permission will result in the invalidation of conformity and operating permits. Non professionals should check the conditions and requirements of the usage area before putting it into operation.
