General
nmas® is a registered trademark of Nome LTD. nmas® is an abbreviation of
Nome Monitoring and Analyzing System.
This manual describes the usage of nmas hardware on unit. More info can be

Product description
Nmas is an on-line condition monitoring system. Nmas can be used to monitor
different sensors and signals. System can be used as an individual signal
converter or as a collector and data analyzer.
Safety information
Information in this manual should be followed carefully to avoid electric
hazards and dangerous situations. Misuse of hardware may lead to equipment
or human damage. Wrong settings can lead to false signal scaling,
disinformation or might cause machine failures. Please use professionals for
configuration changes.
Manufacturer recommends twisted and shielded pair cable or other sensor
manufacturer's recommended cable for all the sensor connections.
Do not install the sensor cables near high voltage cables.
Unconnect the sensors from the cables when welding or other high voltage
operations are occuring near the sensors. Make sure that high voltage
operations near the sensors do not damage the sensors.
Manufacturer is not responsible for damages made during installations.
If sensor is not connected, set the channel off to avoid any false diagnosis.
Intended use
Nmas is a condition monitoring device. It has multiple different features so
usage may vary. Nmas should not be used as security device without
consulting the manufacturer.

Terminology
Measurement interface (MI)
Nmas supports multiple signal and sensor connections. Some of these are
sensors but nmas has no limitation of the input type. All data entered to nmas
comes from Measurement Interface.
Examples of mesurement intefaces:
•acceleration sensor (IEPE type)
•pulse sensor
•pressure sensor
•oil particle counter
•modbus interface
•digital sensor
Signal
Some measurement interfaces provide timebase data. This data is described as
signal in nmas. Signal is sample of data during limited time frame. Signal is
used for further analysis and can be stored for later analysis. Signal is typical
for acceleration and voltage inputs.
Picture 1: Signal from acceleration sensor.
Figure
All trend data is handled as figures. Figures are single number values
representing data from measurement interface. User can attach multiple
figures to same signal. Typically figures have relation to physical quantities.
At least one figure should be linked to every measurement interface. Figure
names are used in data views and reporting.

nmas Simple
Picture 2: Figures
Nmas supports figure calculations in two levels. Levels are defined as
hardware level and software level. Difference between levels is that
calculation of hardware level figures are done immediately when data is
measured. Software level figures are calculated when data is stored to
database. Software level figures can also be calculated anytime after data has
been stored.
Nmas hardware level figures can be related to peak, mean or rms values of
relating data. Software level figures have no limitations. Data in nmas storage
can be manipulated, recalculated and associated to other signals as desired.
Please note that some software level figures have to be specially added to nmas
and are not included in standard user interfaces.
Warning and Alarm
Nmas warnings and alarms are always related to figures. All figures can have
individual warnings and alarms. As in figures nmas supports two levels of
warnings and alarms. Levels are defined as hardware level and software level.
When using warnings and alarms it is important to notice that only hardware
level warnings and alarms are calculated immediately when data is measured.
When warning or alarm information demand immediate actions they should be
configured as hardware level warnings and alarms.
Nmas hardware level warnings and alarms can be related to peak, mean or rms
values of data.
Picture 3: Trend data with warning and alarm limit.

Warning and Alarm onfigurations
Warning and alarm configuration allows user to define how warnings and
alarms are treated in measurement hardware and software. Common to all
''warnings and alarms'' is that they have multiple triggering levels. Basic set up
of levels is two. These two levels can be understood as warning and alarm
level.
Passing ''hardware level warnings and alarms'' always triggers data storage. If
action is related to ''figure'' calculated from ''signal'' all related data is also
automatically stored. With this operation user can always verify the reason for
alarm action.
Nmas can be configured to react on every ''figure'' level passing. This is usually
not desired since it can lead to very high amount of data storage. Usually at
least one direction of level passing should be set to values higher than 10. In
typical condition monitoring situation both passing counter values should have
values higher than 10. Due to this behavior data in trend can be higher than
warning or alarm limit without any triggered warning or alarm actions.
Reacting on level passings is controlled with configuration parameters count-
up and countdown. Count-up defines how many times figure value has to be
higher than level before level actions are triggered. Countdown amount defines
how many times figure value has to be lower than set level before level actions
are triggered.
Picture 4: Figure is higher than alarm level in five su sequent measurements and alarm is
triggered with count-up value of five.

Picture 5: Figure is higher than alarm level in three su sequent measurements and alarm is
not triggered with count-up value of five.
Nmas Hardware
nmas Simple
In nmas Simple hardware components Sensor Unit (SU) and Local Data (LD)
are combined in one housing. Other hardware components can be added as
external units.
Nmas Hardware omponents
SU (Sensor Unit)
Sensor Unit (nmas SU) is used to measure data from different kinds of sensors.
Data can be vibration sensor data or data from any other sensor providing
signal between 0 - 30 VDC. Data can be processed inside unit to enable
characteristic value outputs. SU uses Ethernet or radio for communication.
Unit can be configured for different measurements. Configuration is stored in
LD.
LD (Local Data)
Local Data (nmas LD) is a unit to locally store and display measurement data.
LD can store up to 500 MB of measurement data. This is usually more than six
months of measurements.
Data samples from nmas SU are stored as raw signals. Also selected
characteristic values are stored for faster analysis. All raw signals can be
downloaded and processed for more accurate analysis afterwards.
When database is coming to it's size limitations cleaner activates and removes
parts of oldest data.
nmas LD communicates to nmas SU with wired Ethernet or wireless radio
(special orders).

nmas Simple
LD can be equipped for remote connections and analysis. Remote connection
can be made via wired or wireless Ethernet.
LD is used as a cloud server for measurement data and software components in
local network.
RD (Remote Display)
Remote Display (nmas RD) is unit to display data in local network. Typical
usage is to present data in control rooms. RD units do not store data. All
visible data is downloaded from nmas-cloud. Data clouds can be in nmas
server or nmas LD. Remote Display can show data from multiple nmas-clouds.
WR (Wireless Router)
Wireless Router (nmas WR) is used for routing data in wireless nmas-network.
Routing can be a combination of Ethernet, wlan or gsm data transfer.
Server
All nmas units can operate individually. Nmas server can be used for central
data storage, long time data storage, remote access, database manipulation and
big data analysis. In small installations nmas server is usually not needed.
Nmas Software
All nmas softwares need Java 7 or higher to run.
nmas Simple software
nmas Simple is shipped with “LD View” and “View” software. nmas Simple
unit is used for hosting “View" software in local network.
nmas RD software
nmas RD is shipped with “View” software.
nmas Server software
Server is used for hosting all software components.
Nmas Software omponents
LD View
nmas LD view software is used to display latest results on small displays. Most
typically LD view software is used on nmas LD unit. Software allows user to
view latest results as a list and a trend. LD View user interface also allows user
to change some values related to measurements.
View
nmas View software is used for viewing data. It can be used for viewing data
in different formats. Basic view is to follow measurements as trend data. nmas
