Minimising production stoppages and reducing
maintenance costs part of our objectives as well
as important conditions for your profitability.
To meet this target, we have designed MOVISCAN, first
system associating :
local protective monitoring of machines with in situ
or remote diagnosis
Monitoring machines with steady or variable
operating conditions
A double interface : for one for Process control
(alarm status), the other one for maintenance
department (vibration data for diagnosis).
All this with an architecture dedicated to reduce
installation and cabling costs.
More than a new monitoring spectrum. MOVISCAN is a
new monitoring concept.

MOVISCAN is a unique system designed
to monitor your machines automaticallyand provide pertinent
information to
maintenance personnel on their status :
A SINGLE CABLE :
3 uses :
Continuous monitoring
Automatic datacollection
Remote diagnostic
HIGH-PERFORMANCE
AND USER-FRIENDLY :
MOVISCAN uses high-technology components
enabling to monitor and analyze complex
machinery : spectrum, envelope, Kurtosis, synchro-
nous analysis, etc.
MOVISCAN is equipped with an RS232 or
RS485 interface for local operation and a
modem link for remote operation
A single software application, the DIVADIAG,
is used for MOVISCAN configuration, machine
monitoring, data storage, trend analysis anddiagnostics.
EASY AND ECONOMICAL
TO INSTALL :
the system's architecture minimizes the length of
the sensor/MOVISCAN cables via the use of :
eight-channel SCANBOX multiplexers
connected to the sensors installed on the
machines to be monitored
a SCANBUS bus enabling sensor signals to
be relayed to the MOVISCAN

D E S I G N E D T O C O N T R O LCOMPLEX MACHINES
8 command inputs enable machine operating
conditions to be taken into account automatically ;
as the system is entirely automatic, it must be
capable of taking into account machine operating
conditions :
in order to manage monitoring tasks efficiently
(the system's resources are entirely dedicated
to operating machines and ignore machines
which are not in operation)
in order to analyze data, as machine operating
conditions are often essential to a reliable
diagnostic.
8 Trigger for synchronous analysis
Multiplexing bus interface enabling the
connection of up to 128 sensors using a single
cable
4 relays are triggered in case of alarm or
monitoring system defect
Modem Link for remote dialog with a DIVADIAG
control and analysis station (remote diagnostic).

FLEXIBILITY
Each MOVISCAN can carry out differentfunctions according to how
its is pro-
grammed by DIVADIAG software :
Continuous monitoring : MOVISCAN scans all
the sensors continuously and computes the
parameters of the defects to be monitored
(unbalance, alignment, gear meshing, bearings,
etc.). If the tolerated thresholds are reached, the
monitoring parameter values are sent to the PC
and the alarm or danger relays may be triggered
Automatic data collection : further to anautomatic request sent
by the PC, data such as
overall vibration level, spectrum etc. are sent to
the DIVADIAG software for trend follow-up and
analysis
Remote diagnostic : periodic measurements
can be programmed at any time if additional
information is required for a diagnostic. These
measurements intervene momentarily in the
continuous monitoring cycle.
HIGH-PERFORMANCE
Multiprocessor structure : MOVISCAN is designed
around a PC which manages the various data
transmission and management tasks, associated
with a special processor for signal acquisition
and processing
Measurements are accurate thanks to the 16-
bit analog-to-digital converter and the 32-bit
floating-point digital signal processor.

EASY AND ECONOMICAL
TO INSTALLThe MOVISCAN's structure makes for easy
ins tal lat ion : a single SCANBUS cable enables
the connection of up to 16 SCANBOX multiplexers
per MOVISCAN. By placing the multiplexers near
the machines, wiring costs are reduced. In
addition, as the multiplexers and accelerometers
are supplied by the same SCANBUS cable, no
power supply source is required near the
machines.
USER-FRIENDLY
The data measured is analyzed using the DIVADIAG
software. Its user-friendly interface enables easy
access to the various configuration, monitoring,
trend analysis and diagnostic functions.
DIVADIAG is also compatible with portable data
collectors for the monitoring of less strategic
machines. It also enables oil-analysis result
management. You can also choose to carry out
multi-technique monitoring of your entire machinepark using the
same tool and the same database.
The telephone modem link enables analysis data
from several MOVISCAN modules to be sent to
your vibration analysis center, at any location.
The monitored information is also available locally
via front panel leds, relay outputs and an
RS485/Modbus link with Process Control.

Monitoring of paper machine using acce-
lerometers and temperature sensors located
at strategic points (press, drying rollers, etc.).
Advantages offered by MOVISCAN :
- measurements always done in identical
conditions (e.g. speed), thereby facili-tating diagnostic
- placing SCANBOXES near the
machine minimizes wiring and
installation costs
- use of envelope detection for
low-speed roller diagnostic.
