Important Messages and Requirements
The following messages are important information which require special care in order
to have a safe and reliable IMx-T system.
Important messages, instructions and information in this manual must be
carefully followed. Otherwise, harm might occur to equipment and/or personnel.
In order to ensure a safe system, installation, configuration and maintenance of
the system must be done by trained personnel only.
IMx-T unit contains circuit boards that are static sensitive. Therefore, use
appropriate precautions to prevent ElectroStatic Discharge (ESD) when handling
circuit boards.
Different types of card must be positioned correctly in the rack. The positions of
the different types of cards are shown in Front Panel with Labels within
Drawings and Connections section.
In general, all signal cables must be routed as far away as possible from the high
voltage cables.
It is recommended to always use high quality shielded cables and care must be
taken to ensure shield is properly connected to eliminate interference and noise.
Grounding procedure must be handled with special care to prevent ground loops.
In general, it is recommended to connect shield to ground in only one side of the
senor/signal cable to avoid ground loops to occur.
IMx-T must be connected to protective earth since surge suppressors are
connected between network terminals and protective earth.
Make sure that protective earth is properly connected before connecting any of
the input or output terminals of the unit.
IMx-T unit must be situated in a cabinet with a metal bottom or plastic bottom
with flammability classification of at least V-1. The cabinet must fulfill at least IP
20.
All wires and cables connected to input and output terminals shall have a
flammability rating VW-1, FT-1 or fulfill the requirements according to IEC
60332-1-2 or IEC 60332-2-2.
Because of the redundant power supply, both supply circuits must be
disconnected before maintenance.

Introduction
Important Messages and Requirements
SKF Multilog On-line System IMx-T1-6
User Manual, Revision F
DIP switch settings must be handled with special care to prevent any damage to
IMx-T unit:
·Do NOT change DIP switch settings while the IMx-T unit is powered-up, as
this may cause damage and void warranty.
·Before powering up the IMx-T unit, make sure that DIP switch settings are
properly set to match the recommendations for the connected sensors.
Incorrect settings may cause permanent damage to the IMx-T unit.
IMx-T is a Class A equipment intended for use in an industrial environment.

System Overview
User Manual, Revision F
System Overview
IMx-T is a part of the SKF Multilog On-line System product range. IMx-T is the next
generation of powerful, cost-effective solutions for a variety of condition monitoring
applications.
In conjunction with SKF @ptitude Observer or Analyst software, Multilog IMx-T provides
a complete system for 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, IMx-T with @ptitude Observer/Analyst
The picture above illustrates how IMx-T units are linked together in a network that is
connected via a LAN (it can also be a modem or GPRS router) 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.
@ptitude Observer or Analyst clients can also be installed on the same computer as
@ptitude Observer Monitor or Analyst IMx Service login 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 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-T together with IMx-S and/or MasCon systems.

Figure 1-2: SKF Multilog On-line System IMx-T
The above picture shows a SKF Multilog On-line System IMx-T with two redundant
power supplies and two CPU/IO pair cards mounted.
Designed to fit into a 19" rack enclosure, a Multilog IMx-T is equipped with the following
components:
Power supply units
·Two redundant power supply units
CPU/IO pairs
·Up to four pairs of CPU/IO cards
·Analogue channels
16 to 64 analogue signal inputs.
The dynamic signal inputs are configurable for a side variety of sensors.
Signals, such as acceleration, velocity and displacement or other
parameters are easily adopted. Each input can be configured for standard
accelerometers, 4–20 mA or ±25 V.
Several measurement points may be attached to one channel and both AC
and DC measurements can be measured on the same channel
·Digital channels
8 to 32 digital channels which may be used for measuring speed, trigger or
digital status e.g. indicating when a measurement can take place.
Storage Capacity
Each IMx-T unit has 8 MB flash memory used for the following:
·2 MB for firmware, configuration files, etc.
·2 MB for trend value buffer
üAbout 13 000 vibration trend values can be buffered
üSpeed and process data use half the space of vibration
·4 MB for spectra and time signal buffer
üAbout 250 spectra using 1 600 lines with phase and time signal can
be buffered

User Manual, Revision F
üIf you use more lines, the number of spectrum is reduced.
üIf you use less lines, the number of spectrum is increased
·When the buffer gets full, the oldest data is thrown away.
IMx-T's Unique Features
·Individual conditions for alert and danger may be set for each
measurement point.
·Each channel has indicators for alert and danger. Alert and danger levels
may be controlled by machine speed or load. However, it is also possible to
manually bypass the alert and danger functionality.
·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.
Initiating IMx-T
Initiating an IMx-T is simple to carry out.
·This is done through an initiating program, @ptitude Observer or Analyst
software, and a (portable) computer using RS232 serial interface.
·All initial network configuration parameters, such as IP address, IMx
identification number, etc. are stored first in a separate configuration file,
then transferred to the IMx-T memory.
·The configuration is retained in the event of power losses, so that the
IMx-T can start automatically when power returns.
