Basic hardware explanatory notes
We would like to explain a few terms in the beginning of this manual.
The Adash DSP board
The Adash DSP (Digital Signal Processing) board is the most important part of the instrument. The
special chip provides all necessary operations, which are required for achieving of 4 channel
synchronous data.
4-20mA current loops and its industrial use
For industrial process control instruments, analog 4–20 mA current loops are commonly used for
analog signaling, with 4 mA representing the lowest end of the range and 20 mA the highest. The key
advantages of the current loop are that the accuracy of the signal is not affected by voltage drop in the
interconnecting wiring, and that the loop can supply operating power to the device. Current loop
outputs of actual value are then used in control systems (PLC).
The current loops used in the A3716 are isolated from measuring circuits. They must be externally
powered (they use passive mode).
Relay outputs
Two relay initial states exists. Energized and de-energized. Energized relay is initially powered and its
internal connections are as seen on the picture below (NO-normally opened, NC-normally closed,
COM-common are standard electrical terms). De-energized relay is initially not powered. Internal
connections are seen on the pictures.
Latched relay
We describe it on example:
The factory initial state of the relay is de-energized (i.e. NC and COM is connected). The ISO RMS
(10-1000Hz) value is measured on the machine. When the RMS value will exceed 2 mm/s, then the
relay will switch on the red light in a control room. When the vibration value will decrease under the
2mm/s, then the relay will switch off the light.

If the LATCH function is chosen, then the relay will not switch off the light when the vibration
decreases less than 2mm/s. The relay keeps the switch ON until it is manually switched off ( through
the use of REL–RST).

A3716 IP address setting (the same for the
A3800)
A3716 rack basically behaves as a local PC and it has its own IP address under which it is recognized
in your network. Most common situation is that you will need to change the A3716 rack IP address
because of your company’s policy.
Remark: If you don’t need to change the rack IP address, skip to chapter: Network for data transfer
There are two ways how the setup the IP address.
A3716 (A3800) as a stand alone computer
Windows OS is installed on A3716 measurement unit, so it is possible to connect with it like to a
common PC. Connect USB keyboard, mouse and monitor (VGA interface or HDMI interface). In
Windows login as a "remote" user with "remote" password and follow the chapter IP address setting.

Now you should create required database (tree) structure. The following hierarchy has to be done
MachinePointData Cells.
See DDS manual about how to create the tree structure. All data cells in the tree will be used for
online readings.
If you have not installed the MySQL connector odbc (part of Adash server, see previous chapter), then
the Online item is not displayed.
Microsoft SQL Server can be also used for data.base. Set the Global Setting/ General/ Other/ Allow
MS SQL to yes.
Measuring unit and database connection
After measurement point creation you have to assign the A3716 unit.

The readings will not appear immediately after you start the data collection. The data download is
arranged in batches of many readings. The interval between downloads is set in the Global settings in
the Online tab, Data Tansfer item. Do not use short interval (less 60 sec), the server may be
overloaded.
Graph refresh time interval
The graphs are refreshed manually (Manual button) or automatically (check the Auto box).
Refresh interval is edited in the global settings in the Online tab. Use Auto Refresh Interval.
Remember that graph refresh does not make any new reading. Refresh makes new reading from the
database only

Conditional measurements
The Adash allows to set up a conditional measurement of the controlled data cell by the value of the
controlling data cell. For example: When the Order analysis data cell is set that its controlling data cell
(ID parameter of controlling data cell) is speed data cell and valid interval is 2500-3500 RPM (Min and
Max parameters), then the measurement of order analysis will be take only in this interval. Data saving
is then controlled by Adaptive algorithm (see Adaptive algortihm chapter).
The ID parameter of target data cell then indicates that all data of the data cell will be stored into data
cell with specified ID.
Temporary stop of readings
You can simply stop readings for whole A3716 unit or for one point (it means one channel) or for one
data cell.
Push the A3716 Units button. Select the A 3716 unit. Push Edit button. Uncheck the Enable box and
push OK. All readings made by this unit will be stopped. When you check back the Enable box then
the readings will be taken again.

As the units A3716 are accessible to all users in network, the more users can use the unit at the same
time. To avoid this situation we use the functions Lock/Unlock. When you use the Lock function, your
computer and database is registered in the A3716 unit as the only one computer which can have
access to online data collection. The other users cannot change the configuration in the unit.
The Lock function of the unit is used automatically when data collection is started.
The Lock or Unlock can be done manually (Advanced function).

Adaptive algorithm for readings
The A3716 can take readings (setting using the DDS) completely different way than other systems.
Let's explain it on example. In the past the time interval between readings must have been defined.
E.g. if 1 minute was defined, then the reading was triggered every minute. The time length of reading
was e.g. 1 second. If the change in vibration level occurred during this minute, it was not captured.
The new adaptive system measures continuously. If one reading length is one second, then new
reading is taken every second. You can not miss any change in vibration level.
If all these readings would be continuously stored, then the size of the database would enormously
grow. Hard drive size would be filled very quickly and the access to the database would be very slow.
That is not allowable.
Therefore the adaptive algorithm was developed. This software is installed in each A3716 unit. It
controls, which reading will be saved to database and which will not. The basic rule is that it is not
necessary to store the reading that is the same as the previous one.
How does the algorithm work?
We will demonstrate the algorithm function now. We want to measure the static value (overall value).
Each reading is checked whether it is valid ( ICP error, overload). The invalid reading is removed.
When the system runs for the first time the first reading is always saved.
The capture of local extremes follows. Let's suppose that last values are 3.5 and 3.8 mm/s. It is the
increasing trend (3.8 is higher then 3.5). We want to capture local extremes. If next reading is 3.1mm/s
then the 3.8 is the local extreme and it is saved to database.
The basic function of the algorithm is to save significantly different readings. Significant change is
evaluated on the basis of two relative limit levels (e.g. 5%) and absolute (0.1 mm/s). If the value of the
current measurement differs from the last stored by more than 5% and also more than 0.1 mm/s, then
it is the significant change and the reading is saved. The reasonable amount of readings should be
saved. If the vibrations are oscillating, then the relative limit level is increased. When the vibrations
again becomes stable, then the level is decreased. The special procedure is used for runup and coast
down.
The next thing algorithm is checking is time interval between last saved reading and current. If this
interval exceed the allowed value, then the current reading is saved. Even if there is no significant
change.
Large dynamic readings processing
When the user defines large dynamic readings (too many lines or samples) then the readings are
saved only when the time interval between expired defined value.
Data saving example
Next graphs contains examples of trend with various relative limit levels. The first graph contains full
data and next are taken with 5%, 10%, 20% and 50% relative limit level. As you can see, no
information is lost.

Variable settings of data collection
All control parameters are saved in A3716 unit in file c:\A3716\data\online.cfg. The factory setting
uses the adaptive algorithm, but you can use also user modified collection control. It is strictly
recommended to create backup copy of file before modification. Please, modify only the items, which
you fully understand.
You can modify this file via DDS. In A3716 units list use right-click and Download online.cfg. You
save it and you can edit it by Notepad. Use the Upload online.cfg to send it back to A3716 unit.
New parameters are applied after the project is restarted ( or A3716 unit is restarted).
Regulator section
Find the section [Regulator] and modify parameters.
all readings
0 = adaptive algorithm or time interval savings is used for data storing (dilution).
1 = all data will be saved to database (only for limited time recommended, the disc can be
full filed very quickly)
adaptive
0 = adaptive algorithm is disabled
1 = adaptive algorithm is enabled
short dynamic max samples
the maximum samples number, which is allowed for adaptive algorithm on dynamic
measurements (called short dynamics). Longer measurements are saved only in
long dynamics interval save
statics interval save
the number of seconds
if the adaptive algorithm is used, then it is the max time interval between saved static
measurements
if the time interval saving is used, then it is the time interval between every saved static
measurements
short dynamics interval save
the number of seconds
the same meaning as previous item, but used for short dynamic measurements
long dynamics interval save

algorithm is never used for long dynamics
Examples
To save all data
all readings=1
Note: All readings (measurements) will be saved (according to measurment length). Beware that this
option can fill the hard drive very quickly.
To save data only in defined intervals
all readings=0
adaptive=0
statics interval save=60
short dynamics interval save=180
long dynamics interval save=3600
Note: Adaptive algorithm is disabled. Static readings (measurements) will be saved every minute,
short dynamics every 3 minutes and long dynamics every hour.
Use adaptive algorithm
all readings=0
adaptive =1
statics interval save=21600
short dynamics interval save=21600
long dynamics interval save=21600
Note: Adaptive algorihm is enabled. Static values, short dynamics and long dynamics are saved every
6 hours if there is no change according to adaptive algorithm.
