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

Installation
The installation of an IMx-P must be carried out according to the instructions and
advice given in this manual. Any deviation from these directions can be made only after
consulting with the SKF Condition Monitoring Center Luleå. Installation errors can lead
to a situation where the system does not work as intended and machinery faults go
undetected. Therefore, contact the IMx-P application engineer at the slightest doubt
during the installation.
Note - In general, all cables must be routed as far away as possible from high
voltage cables. If this cannot be done, care should be taken to use high quality
shielded cables.
Sensor Cables
When routing a sensor cable, it is important that the cable is firmly fixed. The cable may
never be allowed to vibrate or oscillate, since this effects the capacitance of the cable,
and thereby the measurement result.
The sensor cable may not be routed or bundled together with supply cables because it
generates strong magnetic fields.
To connect IMx-P to sensors, the following type of sensor cable is recommended:
•Shielded, twisted pair 2 x 2 x 0,5 mm2(FKAR-PG 2 x 2 x 0.50mm2, DUE 4002 or
corresponding)
Power Supply
An external power adapter is used as the power supply. SKF provided power supplies
must be used with IMx-P. Power supplies differ in characteristics in ways that are not
obvious, and there are also physical differences in the DC-plug.
Power Connector
Power connector is a standard main connector.
Cable Shielding
IMx-P sensor inputs are differential type.
Note that the sensor cable screen needs an external ground connection.

Communication Cable
For lengths up to 15 metres, it is recommended to use pre-fabricated Ethernet twisted
pair cable FTP type, CAT5/6.
For longer cable lengths, it is recommended to use S-FTP (screened shielded twisted
pair) Ethernet cable CAT5/6.
Data Communication
IMx-P unit data communications are compliant with the Ethernet standard 10/100
Mbit.
IMx-P has two Ethernet ports which work like an internal switch.
Ethernet Cable
The Ethernet TP cable on the IMx-P is connected to a standard Ethernet RJ45
connector. Both Ethernet ports have auto detection of crossover or straight through
Ethernet cable connection. Basically, IMx-P has a built-in Ethernet switch.
It is possible to connect several IMx-P units in a daisy chain with up to eight units in a
single cable layout.
There are two LEDs on RJ45 connector.
•Yellow LED is the Ethernet traffic indicator which flickers whenever there is traffic
on the network.
•Green LED is the Ethernet link indicator which lights up when the system is
correctly connected to another network device.

external power)
•Digital channels 5 to 8 have trigger level 10 V (power off for 12 to 24 V pulse with
external power)
Network Configuration
All IMx-P units must have an identity number between 1 and 255, unique to the
database to which it is connected.
It also requires network settings and the IP number and port number of the @ptitude
Observer Monitor or Analyst IMx Service to which it should be connected.
The network configuration is done through;
•For Observer clients, On-line Device Configurator in SKF @ptitdue Monitoring Suite.
For detailed information, refer to @ptitude Observer On-line Device Configurator

Network Configuration
There are two ways to configure the network:
•by software: is configured by the software via On-line Device Configurator or
Multilog IMx Configurator.
•by DIP Switches (Hardware): is done by configuring HEX rotary DIP switches
manually.
Configure by DIP Switches (Hardware)
If you have decided to configure the network manually by hardware, the following logic
must be fulfilled.
•The factory default configuration TCP/IP address is 10.0.0.1XY.
•The configuration of DIP switches requires you to set the first three part of the IP
address at Create IMx/MasCon16 Config screen of On-line Device Configurator or
Multilog IMx Configurator.
•However, the last part of the IP address will be controlled by the HEX rotary
switches on the IMx-P unit.
•For example, 10.0.0.1XY, where XY will be derived from HEX rotary switches.
•These last two digits will also form the unit ID.
•The Hex rotary switches for IMx-P are located on the front panel, labeled as HEX1
and HEX2. Refer to IMx-P Front Panel in Drawings chapter for the physical
locations.
•The HEX rotary switches have to be set manually with a small screwdriver.

Key Features
Export ODS Data
The measurement data collected by IMx-P unit can be exported to be used for ODS
(operating deflection shapes) analysis. ODS analysis generates a 3-D model to illustrate
how the structure and machinery respond to the dynamic vibrations. Therefore, points
of excessive deflection, structural weaknesses and resonances can be identified and help
understand how the equipment behaves dynamically under working conditions.
The export of measurement data is done through @ptittude Observer, a function called
Export ODS data which can be found within Measurement Date interface.
Export ODS data exports a selected measurement incident to a universal file format
(UFF) which then can be imported into a software that can do machine movement
animation such as ME' Scope.
For more information on how to use this function, refer to @ptitude Observer User
Manual / System Operation / Measurement Date.
For more information on ODS analysis, for those with the access to SKF Media Finder,
may refer to the publications on NMO ESS.

Example of Diagnostic Expert System Graphic Displays.
Transients
A transient is considered as a non-stationary vibration event due to changes in loads or
process i.e. run-up or coast down events. In these cases, the spectral components are
dispersed in the spectrum making it impossible for analysis.
However, with transient groups in @ptitude Observer/Analyst, it is possible to analyze
this kind of events using an appropriate configuration depending on clients needs.
