1. Introduction. Warranty conditions
In this documentation there is no service and diagnostic information such as
schematic diagrams or diagnostic clues related to UG-S/A. The manufacturer
guarantees high quality and reliability of device. In case of any defects resulting
from mistakes in the assembling process, during the warranty validity period,
customer has the right to request for unpaid repair. All defects should be
reported to the manufacturer. Warranty period is extended by number of days
needed to repair device, which are counted from delivery to manufacturer to send
off day. In case of any failures, repairs are made only by manufacturer, the
repairs are free of charge if failures are caused by manufacturer and if warranty
period hasn't expired. If failures are caused by user then the repairs are charged.
Customer isn't allowed to open and make any changes or repairs in the
equipment.
This warranty does not cover any defect caused by an accident, misuse, improper
installation or operation, unauthorized repair or maintenance and damage caused
by improper supplying device (voltage lower than 180V and higher than 240V).

2.3 Destination
UG-S/A generator is designed to power the ultrasonic ceramic transducers by
sinusoidal voltage/current with frequency in range 18 - 22kHz. This frequency is
manually adjustable with 1Hz interval or automatically in automatic mode, where
device is working in selected frequency range. This range is related to resonant
frequency of the transducer. Generator enables measurement of frequency
characteristic of the transducer in frequency range 18 – 22kHz, which helps to
find optimal work frequency and matching impedance.
1. Frequency of the output signal could be changed
in range 18-22kHz with 1Hz maximum resolution. This range depends
on device version and it is possible to obtain larger (1 -60kHz). Output
signal is based on quartz generator.
2. Maximum output power is 00W and it is regulated by change
output voltage. This is done by driving power stage by PWM signal.
Pulse width is defined as ratio of time t and T. This is shown on the
following picture:

Do not cover the fans, this may damage the generator!
3.2 Guidelines for user
Before power ON please check:

7
• accuracy and confidence of connections
• condition of cable insulation
• use only mains socket with fully efficient grounding pin
• to attach load (ultrasonic transducer or model resistance), use only
cables with appropriate insulation class
If the device is in operation:
• do not touch /do not short load (ultrasound transducer) connectors
• do not leave working generator without supervision
• signal output must be disabled before changing the load (ultrasound
transducer); it must be done in all operating modes (spectrum analyzer,
power analyzer, continuous work); switch button F1 in STOP position (the
color will change to red) and check if LED indicator (“Output”) on front panel is
deactivated
• do not change the fuse
• do not disconnect mains cable
• do not disconnect RS232 cable
Before replacing the fuse the generator must be turned off – exit the program
(F10), turn off the PC, turn off the device and disconnect mains cable.
Replace the fuse only with identical one (see the description below the fuse
socket) (glass body x20mm 6.3A 2 0V (quick-acting)).
WARNING!
FAILURE TO FOLLOW THESE RULES MAY CAUSE SERIOUS INJURY OR
DEATH.
The user is responsible for any damages or injuries caused by the
improper use of the device.
3.3 Installation and first use
1. Before turning on the PC – connect RS232 cable and screw it down to avoid
disconnection during work.
2. Turn on the PC.
3. Install software from included CD/DVD: click on setup.exe to start Wizard
installation program and follow the steps.
4. After installation (before first start of UG-S/A) reset your PC
. Check if the load (ultrasound transducer) is connected properly.
6. Turn on the generator (4th socket on back panel)
7. Start UG-S/A software (UG-S/A.exe)
If the software is properly installed the following files are created as in the example:
<root> UG_SA

3.4 Software description
After starting UG-S/A software, main panel appears on the screen. It is shown
below:

7. Generator condition panel
8. Function buttons
• Measurements anel
This panel shows actual data measured by the generator.
• Settings anel
This panel is used to set generation parameters: power and frequency. UG-
S/A software allows the generator to work in two modes: automatic or
manual frequency setting. In automatic mode the generator automatically
adjusts to the resonance frequency of the transducer and keeps it. In
manual mode user sets desirable frequency.
• Generator condition anel
Below the main panel, is located a status bar of RS232 port where user
may found actual status information.
In case of transmission errors, appropriate information will be shown on
this panel. If this happens, user should check if generator is on, if the

1
device and PC are connected properly and if some other applications are
using this communication port. After this kind of error occurs, the user
should re-detect the device (F8 button and then “Find”).
On this panel user also may found indicators:
• Unite connected – the device is detected and is configured properly,
• Voltage too high - voltage exceeded the maximum permitted level,
• Current too high - current exceeded the maximum permitted level,
• Power too high – power exceeded the maximum permitted level,
• Tx line of RS232 active – the PC is sending some data to the
generator,
• Rx line of RS232 active - the generator is sending some data to the
PC.
•
Function buttons
There are two ways of using function buttons. User may click on them using the
mouse or use function buttons on his keyboard (F1 – F10).

After start, the software automatically detects the generator. If it is done, the
yellow indicator (“Unite connected”) on the generator condition panel is lighted.
If the generator isn't connected properly or the power is off, the „Characteristic”
function gets blocked. In that case user should re-detect device - “Find” button.

Normal working mode.
• set desirable output voltage level (%) and start frequency
• run the generator by START button (or F1 button)
• during work the user may change voltage and frequency
• if power, voltage or current exceed the maximum permitted level,
generator is stopped (as STOP/F1)
Measuring load frequency res onse.
To measure load frequency response click „Characteristic” (F ) button on main
panel. From that time, device works as analyzer.

If you click START (F1) button for chosen range and frequency with declared
interval (s) (6 part), the characteristic measurement starts.
On this graph, user may chose (by cursor in white color) limits of frequency range
for option „Setting for automatic control”.

„interval” parameter describes time duration between two single steps (frequency
changes) of the scan. The smallest value of this parameter is 0 ms.
In the window described as „Setting for automatic control“ the user may found
values, which are changeable by cursor. They are used in automatic mode (tuning
to the resonance). When user set the desirable phase, generator will be trying to
change frequency to keep selected phase. Phase could be set to 0, but that choice
could be difficult to realize. In this mode generator changes frequency in range
selected by cursor.
In the left, on the bottom of the window, there is shown a table with measured
values. User could choose any of them by selecting by the cursor.
It is possibility to archive measured data (2nd part): voltage, current, power,
impedance and phase. There are creating files in Excels format:
phase: filename_____fi.csv
current: filename ____I.csv
power: filename____P.csv
voltage: filename____U.csv
impedance: filename____Z.csv
frequency: filename____F.csv

The procedure is the same as for the characteristics in frequency domain (paragraph
above)
Fig. 13. Panel of impedance graph in Power domain
Characteristic measurement is started by START (F1) button for selected range of
output voltage and with selected intervals. After scan started, generator is changing
“Out. Voltage Level [%]” with declared step and with declared time intervals (Delay
[s]), on the graph there are printed out impedance and power values.
In the lower left window is shown table with measured values.
The user may set desirable range of X and Y axes (Range).
Also there is possibility to save measured data from the table on hard drive
(voltage, current, power, impedance and phase). They are saved as Excel files:
