Scenario
It is important to assess and evaluate the current site where the system is to be
installed.
Before getting started, draw a plan on a piece
of paper how you would like this
installation to look like after it is completed, then consider if it is possible to achieve.
Among other things, consider lengths of cables, where electrical power to the IMx-S
units can be connected, where the @ptitude Obs
erver Monitor or Analyst IMx Service
should be installed and positioned and who should analyse the data measured. Good
and thorough planning is the basis for a successful solution and installation.
Make a detailed layout of the equipment, the network, and distances between
components. Include specifically the IMx-
S units, the @ptitude Observer Monitor or
Analyst IMx Service computer, the database server computer and all hubs/routers in the
network. Specify network configuration of each components, such as IP addresses and
subnet masks. SKF application engineers and service engineers need these information
in order to assist.
Note that a CAT5/6 Twisted Pair (TP) Ethernet cable has maximum working distance of
100 m. If longer cable lengths are needed, fibre optic cables may be used along with
needed converters such as converters for fibre optic to CAT5/6 (TP) Ethernet and vice
versa.
When GPRS is used, the GPRS routers should be reconfigured as a part of the
application to run a lifeline connection with the Ob
server Monitor or Analyst IMx Service
computer.
Important - Failure of this communication path will force the GPRS router to
reboot itself constantly, and can hamper the success of the application. This is
especially valuable to consider when the GPRS forms a part of the customers
internal IP network (VPN). In such case, SKF must be informed of this before
ordering the GPRS, so that SKF can disable the lifeline functionality of the GPRS
router.
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 since it
generates strong magnetic fields.
Important - In general, all cables must be routed as far away as possible from the
high voltage cables. If this cannot be done, care should be taken to use high quality
shielded cables, such as S-FTP (screened shielded twisted pair) CAT6 for the
network. In difficult cases, it is the safest to use fibre optic cables.
