Introduction

System Overview

IMx-P is a part of the SKF Multilog On-line System product range. IMx-P is a powerful,

versatile device designed to meet the needs of vibration analysts, service providers, and

condition monitoring professionals.

In conjunction with SKF @ptitude Observer or Analyst software, the IMx-P provides a

complete portable solution for temporary installations and troubleshooting activities.

The IMx-P system helps provide early fault detection and prevention, automatic advice

for correcting existing or impending conditions and advanced condition-based

maintenance to improve machine reliability, availability and performance.

Figure 1 - 1.

System Overview with @ptitude Observer/Analyst.

The picture above illustrates how IMx-P units are linked together in a network that is

connected via a LAN to a @ptitude Observer Monitor or Analyst IMx Service. The

@ptitude Observer Monitor or Analyst IMx Service in turn can be connected to e.g. a

LAN network making it possible for several of @ptitude Observer or Analyst clients to

link to this network.

Figure 1 - 2.

IMx-P Connected to a Laptop.

However, most likely scenario of IMx-P setup would be to connect an IMx-P unit directly

to a laptop and use SKF Multilog On-line System temporarily, taking advantage of the

portability.

@ptitude Observer or Analyst clients can also be installed on the same computer as the

@ptitude Observer Monitor or Analyst IMx Service software. Through a general

interface, also known as ODBC (open database connectivity), it is possible to link

@ptitude Observer Monitor or Analyst IMx Service login computer to an existing

database for an existing control or processing system, if desired. The @ptitude Observer

Introduction

IMx-P Unit

Monitor or Analyst IMx Service, @ptitude Observer or Analyst clients and the database

can be separated from each other as long as they are on the same network where

ODBC calls can travel freely.

It is also possible to connect different types of on-line units in the same network, for

example, IMx-P together with IMx-S and/or MasCon systems.

Portable and Battery Powered

The SKF Multilog On-line System IMx-P unit is portable and battery powered.

•The built-in battery with four hours of operation time makes it possible to use in

places with no available main voltage.

•It is possible to use the on-line system temporarily in order to perform

troubleshooting for intermittent faults, installation checkouts for conformity to

purchasing agreements, startups and etc.

•The battery has a capacity of 8,5 Ah, 12 V. The charging time of an empty battery is

about 16 hours (longer charging time is allowed but not recommended).

Analogue Channels

Each IMx-P unit has 16 analogue channels (dynamic and DC).

•The analogue signal inputs are configurable for a wide variety of sensors.

•Any signals such as acceleration, velocity, temperature, and displacement or other

parameters are easily adopted.

•Each input can be configured for standard accelerometers, accelerometer sensor

power on/off by software, and process inputs (±25 V DC).

Introduction

IMx-P Unit

Digital Channels

Each IMx-P unit has 8 digital channels.

•The digital channels may be used for measuring speed, trigger or digital status

indicating when a measurement can take place.

•Digital sensor power is software controlled.

Measurement Points

Each IMx-P unit is capable of configuring measurement points.

•Several measurement points may be configured per channel.

•In addition, Bias Output Voltage (BOV) can be measured and recorded for checking

sensor/cable faults for standard accelerometers.

•Individual conditions for warning and alarm may be set for each measurement

point.

•Warning and alarm levels may be controlled by machine speed or load.

Auto-diagnosis System

Each IMx-P unit contains an uniquely built-in hardware auto-diagnosis system.

•The unit's unique built-in hardware auto-diagnosis system continuously checks all

sensors, cabling and electronics for any faults, signal interruption, short circuits, or

power failure.

•Any malfunction triggers an alarm.

•If the main voltage fails or for some reason is disconnected, the battery power

automatically takes over.

Storage Capacity

Each IMx-P unit has 8 MB flash memory used for the following:

•2 MB for firmware, configuration files, etc.

•2 MB for trend value buffer

–About 13 000 vibration trend values can be buffered

–Speed and process data use half the space of vibration

•4 MB for spectra and time signal buffer

–About 250 spectra using 1 600 lines with phase and time signal can be

buffered

–If you use more lines, the number of spectrum is reduced.

–If you use less lines, the number of spectrum is increased

•When a buffer gets full, the oldest data is thrown away.

Initiating IMx-P

Initiating the IMx-P is simple to carry out.

•This is done through an initiating program through @ptitude On-line Device

Configurator or Multilog IMx Configurator tool and a (portable) computer using

RS232 serial interface.

•The Network Configuration parameters, such as IP address, IMx identification

number, etc. are stored in a separate configuration file first, then transferred to the

IMx-P memory.

LED Indicators

IMx-P has LED indicators on the front panel.

•The functionality of battery level indication is controlled by Firmware 2.0 or later

in conjunction with IMx-P upgrade.

•The IMx-P upgrade has been implemented for the Serial Number 1048 and later.

•It takes a minute in a stable condition to get the battery level indication state.

•For the older versions of IMx-P units:

–to get the battery level indication functionality, units must be upgraded

–the battery level indication of not upgraded units is not reliable
