Introduction

Whats new in version 1.80?

• The information which should be displayed in the file
manager can be selected.
• Long lists have a scrollbar which indicates the cursor
position in the list.
• 2-channel measurement with automatic switch (VIB
5.466): The channel (A/B) in the results screen can be
switched over.
• MultiMode: The evaluation setup can be activated/
deactivated in a saved measurement file.

What’s new in Version 1.60?

• Zoom function in the trend display
• Route functions, ‘Production line speed’ and ‘Aggregate
RPM’:
The RPM is calculated and stored for each measurement
location in a production line or on an aggregate. This
function saves the RPM measurement before every shock
pulse measurement (for normalization) or before every
FFT spectrum (display of RPM-dependent characteristic
damage frequencies).

Changes in the VIBSCANNER setup:

• Time format: 0-24h / 1h-12h (am/pm)
• Channel A/B switch:
When using the automatic switch, channel A or channel
B can be controlled individually to, e.g. carry out a test
measurement on a channel.
• Unit of ‘(Prod.) line speed’
• Registration: 30-hour trial operation of new ‘Analysis
module’ without any password.

Description

Power supply
The VIBSCANNER is supplied with a NiMH battery that is
charged by a battery charger (VIB 5.420). During the
charging process, the VIBSCANNER is switched off and the
battery remains inside the instrument. Reserve batteries
can also be charged outside the instrument.

F
Note
The NiMH battery loses 1- 2% of its charge (self-
discharge) per day when the VIBSCANNER is switched
off. If you do not need the VIBSCANNER for a longer
period of time (> 3-4 weeks), please remove the
battery and leave it connected to the charger (not in
the intrinsically safe version). Before you reinsert it,
recharge the battery.

When VIBSCANNER is switched on and the battery

charger is connected, the charging process is interrupt-
ed and...
• VIBSCANNER is supplied with mains power.
• VIBSCANNER (intrinsically safe) is supplied with
battery power.

Measurements are not allowed with the charger con-

CAUTION! nected because this can result in measurement errors.
After approx. 10 minutes, the VIBSCANNER loses the
time and date setting if the battery is removed.
Rechargeable batteries must not be charged in explo-
sive environments!

Charging the battery

• Open the protective cap on the battery.
• Connect the battery charger to the battery and to the
power supply.
Before charging, the battery should be discharged as much
as possible. The maximum charging time is approx. 6 hours
(approx. 10 hours for intr. safe battery).

Description

Operating state during charging

The charge level of the batteries is indicated by two LEDs:
• Red lights up: battery is being charged
• Green lights up: battery is charged
• Red flashes: battery is defective or initialization (only
beginning to charge; can flash for several minutes).

Protective cap Level of charge

LED (red, green)

Charge level of the battery

The charge level of the battery appears at the bottom right
of the VIBSCANNER display:

Level of charge
(black= battery full)

Even if the battery exhibits only a very slight memory

effect, it should only be charged when it is completely
discharged. Otherwise, the display of the charge level can
vary from the actual charging status after several ‘incom-
plete’ charging cycles and the following message appears:

Information: BATTERY LEVEL INACCURATE!

VIBSCANNER 09.2003

The battery level display may be inaccurate....

12
Description

In order for the display to show the actual charge level of

the battery again, proceed as follows:
• Leave the VIBSCANNER switched on until the battery is
almost fully discharged when the message appears:
Battery empty

F
Note
If the message appears during a measurement, you
have approximately another 30 minutes time to termi-
nate your work and save the data.

• Recharge the battery again.

When the VIBSCANNER is switched on, the message
‘Battery level inaccurate...’ appears again.
• Discharge the battery again as described above, and
recharge it again.
Only when this step has been completed is the display of
the charge level correct.

Handling VIBSCANNER batteries correctly

1. Never deeply discharge the battery
If the battery is nearly empty, VIBSCANNER automatically
switches off to avoid deeply discharging the batteries. Since
a low residual current flows even when the battery is
switched off, the battery should be taken out of the
instrument if it is to be stored for a lengthy period of time
and charged at regular intervals (1 month) to avoid a
complete self-discharge.
2. Charge and discharge the battery completely:
Repeated incomplete discharging/charging leads to a re-
duction of the battery capacity through the so-called
memory effect and to an imprecise loading status display.
However, this can be remedied by a number of complete
charging and discharging cycles (‘Battery empty’).
3. Store the battery in a cool place
The self-discharge of the batteries increases greatly at
VIBSCANNER 09.2003

higher temperatures. Therefore, the battery should be

stored as cool as possible (0-25°C) or, if the storage
temperatures are higher, it should be recharged more
often. Batteries that are not intrinsically safe should always
be connected to the charger during charging (‘conservation
charging’)

Operation

Program structure
The VIBSCANNER application program is graphic-oriented
and menu-driven.

Graphic-oriented
a) The measurement tasks are started via corresponding
icons on the screen.
b) In the basic version the measurement tasks are stored in
two screens that are opened via the screen icon S1 or S2:
The S1 screen contains measurement tasks for overall
vibration and other important variables (see page 16).
The S2 screen contains measurement tasks for overall
vibration that are optimized for specific machine types
and RPM ranges. The first line depicts the machine types
and the left column defines the RPM range (see page
32).
c) A corresponding selection screen exists for the optional
program modules ‘FFT analysis’, ‘Balance’ and ‘Signal
Analysis’ (details of the optional modules are given in
the ‘VIBSCANNER - FFT analysis and balancing’ operat-
ing manual - VIB 9.664.G).

Measurement tasks are selected

via icons.
The selection screens are
opened via the screen icon at

Shock pulse measurement (bearing condition)

F
Note
To measure high frequency shock pulse signals, use
either the internal vibration transducers, the TIPTEC-
TOR, the VIBCODE hand-held probe or industrial
transducers with a resonant frequency of 36kHz from
PRÜFTECHNIK AG.
Mount the transducer at the location with the strongest
signal within the load zone. The signal path to the
measuring location should be direct and include only
one material transition. For measurement with the
internal transducer or the TIPTECTOR, the measure-
ment location should be prepared with the countersink
bit (VIB 8.610).

• Click on the shock pulse symbol in the main window:

• Enter the parameters required for normalization of the

measured values. The ‘Mode’ parameter can be set by
repeatedly pressing the joystick.
If you do not want to make normalized measurements,
set the ‘Mode’ parameter to ‘No normalization’.

F
Note
The RPM and shaft diameter determine the initial
value (dBi). External influences on the signal are taken
into account in the adapted value, dBa. Both factors
result in the adapted initial value, dBia:

dBia = dBi(RPM; Ø) + dBa

The normalized shock pulse value (dBn) is given by:

dBn = dBsv - dBia ; dBsv: measured value

Adapted measurement tasks - selection screen S2

A reliable assessment of the vibration status of a machine
can be carried out with the aid of suitable variables. It has
been shown that - independent of the machine type and
RPM range - only certain vibration values can be used.
For example, the shock pulse value provides satisfactory
results for high-speed and medium high-speed running
bearings, but, for slow-speed bearings (n<120 min-1), the
vibration acceleration should be recorded.
For these cases VIBSCANNER has adapted measurement
tasks ready that are located in the 2nd selection screen.

RPM-dependent parameters
The RPM is required as an additional parameter in the
following measurements:
• Shock pulse measurement ->
for the normalization of carpet and maximum value
• FFT spectrum ->
for the display of RPM-dependent (damage) frequencies
in OMNITREND
So that the RPM does not always need to be recorded
before each of these measurements, VIBSCANNER together
with OMNITREND provides the following functions for the
route mode:
• Aggregate RPM
• Production line speed

Aggregate RPM
For a single aggregate (e.g. motor-gear-pump), a reference
RPM is always recorded first. The RPM value is then
converted for all measurement locations on the aggregate
and saved together with the results of the measurements
listed above. The conversion factors are defined in OMNI-
TREND and take into account the different RPM relations in
the aggregate (e.g. in gearing).

Production line speed

A production line consists of several aggregates. In the case
of a paper machine, it consists of an aggregate, e.g. the
drive motor, the gear, the bearing roller and associated
bearings.
The RPM at any measurement location can be calculated
from the line speed in a production line (e.g. paper
machine, conveyor belt,...) and the diameter of the in-
dividual bearings. In addition, the different RPM conditions
(e.g. due to gears, slip,...) are taken into account for each
bearing (see previous section ‘Aggregate RPM’).
The bearing diameter and RPM conditions are set up in
OMNITREND, and the production line speed is entered in
VIBSCANNER before the measurement on site.
Example:
Shock pulse measurement and envelope spectra on rolling
bearings with different RPMs.

Before the measurement, you must change the transducer

selected in the transducer setup (see the ‘External vibration
VIBSCANNER 09.2003

transducer’ section on page 58).

Pt 100 An external Pt100 probe is connected to the analog socket
marked in blue using the cable supplied (VIB 5.439). In
order to compensate for the line resistance, an appropriate
offset value must be entered in the transducer setup.

External RPM transducers

... are required for
- externally triggered vibration measurements
- measurement locations that are difficult to access
- 1-/ 2-plane balancing
- Orbit and Phase measurement

Connect the external RPM transducer (VIB 6.630) to the

yellow channel with the supplied cable (VIB 5.432-2,9).

The transducer type is not automatically recognized

when the transducer is connected to yellow channel.
Therefore, before the measurement, check the trans-
FNote

ducer in the transducer setup and, if necessary, change

the setting (see the ‘External vibration transducer’
section on page 50).

* If the machine shafts are very

shiny (polished), the trigger
sensor should not be mounted
vertically to the surface, but at
an angle of less than approx.
10°-15° to the perpendicular.

 67
Appendix

d. To display the current firmware version:

• Switch the instrument off.
• Push the joystick up towards the display and keep it
pressed. The VIBSCANNER info window appears:

SERNO: 00105 04.02.2002 13:04:35

MAIN: 150 (0220) BOOT: 106 (0028)

SERNO: Serial number of the instrument * = Subversion

MAIN: Firmware version (build number*)
BOOT: Boot program version (build number*)

e. To carry out permanent measurements

If you hold down the joystick after starting the measure-
ment, VIBSCANNER measures permanently without car-
rying out any averaging. Only when you leave go of the
joystick does the actual measurement begin with the
selected averaging number.
Application example: Initially, heavily fluctuating values
are measured on a machine that stabilize after a certain
amount of time. This measurement function lets you
trace the incoming values on the screen and to start
recording the data only when the values have stabilized.

f. Signal check (2-channel measurement)

To check the signal before a measurement with the
automatic switchbox (VIB 5.446) on each channel (A/
B), proceed as follows:
• Activate the ‘Display channel A/B’ display option in
the device setup (see page 19).
• Click on ‘A<>B’ in the Setup menu, and select the
channel. Start the measurement.
