Introduction 

Dear Customer, 

Thank you for purchasing this Weber Ultrasonics product. You have chosen a first-class product 

that was developed using the latest technology. 


It is vital that you read these operating instructions and follow them carefully before installing 

or commissioning your product. Failure to observe these instructions can present a risk to life. 

Units may be operated by trained personnel only. Failure to comply with this will result in a loss 

of warranty rights. 

The device may only be operated and maintained by personnel who have read and understood this operating 

manual and are familiar with the applicable legal regulations for accident prevention and workplace safety. 

Safety instructions 

Before starting up your device, please read through the following instructions carefully, both for your own safety and for 

the safety of the device. 

Keep this manual where it can be readily accessed by all systems users. 

Installation is to be carried out by qualified technical personnel only! 

The ultrasonic generator is to be operated by properly trained personnel only! 

Due to the way it operates, additional safety measures must be taken if the device is to be used in areas posing an 

explosion risk. 

Ultrasonics energy is converted into thermal energy during operation. It is essential to ensure that this heat is able to 

dissipate. Depending on the cleaning medium in use, an unchecked heat build-up could result in the formation of explosive 

or readily combustible vapors! 

Only use bath liquids which comply with environmental standards and are tested and approved 

for use in ultrasonic cleaning systems. 

The electromagnetic compatibility corresponds to the standards and regulations listed in the specifications. 

All necessary settings were either made in the factory or are described in this handbook. However, should problems occur 

on start-up, please do not make any prohibited adjustments to the device, as this would endanger your warranty rights. If 

in doubt, please contact our technical service staff. 

Please contact our technical service if at all in doubt. 

Never allow ultrasonics to run in a dry or partially filled bath! 

Always check that the bath is filled up to the proper level marking.


Display:

Never run the transducers dry. The liquid surrounding the transducers should never exceed a maximum temperature 

of 90°C. It may only contain chemicals which do not attack stainless steel 1.4571. The maximum chloride content 

of this liquid may not exceed 40 ppm, as pitting corrosion may otherwise occur. 

Work inside the device may only be carried out to the extent described and, as with the electrical connection, should only 

be performed by skilled personnel. When performing such work, the ultrasonic generator must be completely disconnected 

from the mains (unplug the mains connection). 

Inputs or outputs that are used for controlling or monitoring purposes should be twisted and shielded. 

The device must not be in close proximity to electrically charged components or cables. 

The shielding should be connected to the generator‘s earth on one side of the generator. 

Attention: All connections for the signal or control lines are galvanically connected to the generator. 

Always observe any warnings or instructions given on the device itself. 

The device must always be disconnected from the mains before cleaning or when installing/uninstalling an option. 

Do not use liquid cleaners or sprays. Only use a damp cloth. 

Never operate the device in areas where moisture could penetrate the device. 

The platform for the device must be sufficiently stable, as the device being jolted or falling could cause severe damage. 

Ensure that the power supply specifications given on the device are met. 

Only those transducers which have the correct frequency, power output and dimensions may be used with this generator. 

HF cables from the generator to the transducer as well as mains cables to the generator may not be rolled up if they are 

too long. Instead, they must be shortened to the required length due to the risk of overheating. 

With the exception of the permitted tasks listed in the handbook, you should never attempt to repair or modify 

the device yourself. 

In the following cases you should disconnect the device from the mains and contact a qualified service engineer: 

· If the mains cable or plug is damaged 

· If liquid has penetrated into the device 

· If the device has fallen over or the housing is damaged 

· If the device displays noticeably different behaviour than standard operation 

Attention: Repairs and modifications may only be carried out by competent, skilled personnel.

Notes on the installation location 

During operation the generator will get very hot. If the generator cannot dissipate this heat sufficiently, it will 

display an error message due to excess temperature (see also the “OVERTEMPERATURE” error description). 

In addition, ambient temperatures of over 30°C should be avoided. 

Choose a suitable location that will protect the device from moisture, water, excessive sunlight and heat. 


Attention: 

• Choose a location that will prevent steam or any other aggressive vapours 

from penetrating the device. 

• Over a period of time, chemically contaminated ambient air can lead to 

the device being irreparably damaged. 

Power supply 

The ultrasonic generator draws its power (230 V AC and 50/60 Hz) via the connection cable. 

It has an internal main fuse (10 AF). 

If you need to change the fuses, unscrew the bottom of the housing. 

ATTENTION: 

• For safety reasons, always disconnect the unit from the mains before changing fuses 

• Plug racks into earthed sockets only 

• Always replace blown fuses with new fuses of the same type 

• This should only be performed by qualified, skilled personnel

INTERFACE DESCRIPTION 

1.) Signal “+15 Volt Out” DSUB PIN 1 

A voltage of 15 V is available at this output. This voltage can be loaded with max. 100 mA 

and can, for example, be used to output a voltage for the function HF-DA and/or “Error”. 

This voltage can also be used to switch on the generator on the “Input FS-24 V”. 

2.) Signal “POUT” DSUB PIN 2 

At this output a voltage proportional to the power output of between 1 and 10 V 

(= 0 – 100% power output) is available. 

Reference point = GND. 

3.) Signal “P-EXT.-IN” DSUB PIN 3 

By connecting a voltage between 5 V and 10 V, the output of the generator can be set to between 50% and 100% 

of its nominal amplitude or power. To activate this function, go to the Settings menu (password 6354) and select 

the “external voltage” setting under “Pwr.src”. 

Reference point = GND. 

10


4.) Signal “HF-DA ERROR” DSUB PIN 5/9 

Shared in/output for the internal relays “HF-DA” and “ERROR” 

(these PINs are connected internally). 

5.) Signal “HF-DA” DSUB PIN 6 

If the ultrasonic generator has been switched on via either of the signals “FS-24 V”, “FS-GND” or with the test button 

on the front panel and is emitting HF voltage (i.e. there is no malfunction), an internal floating relay contact is closed. 

(between PIN 6 und PIN 5/9). 


The “root” of this relay contact leads through to a PIN 5/9 (these pins are connected internally) in the DSUB socket. 

This relay contact can now be queried by an external control system. A voltage connected to Pin 13 / X1 can, of course, 

also be switched through (max. 24 V/100 mA). 

It is useful to query this contact when a timer operation is being carried out and the generator switches off automatically 

when the time is up (normally closed contact default setting). The contact can also be switched over to reverse polarity 

in the Settings menu. 

Standard factory setting: Contact closed when the generator outputs HF voltage. 

6.) Signal “Error” DSUB PIN 7 

This is the output of an internal relay (root to PIN 5/9). 

This relay reports generator malfunctions. 

This means that if the generator is switched on and, for some reason, the power output does not 

correspond to the set level, this relay is activated. 

Factory default settings: Closed in the event of a malfunction. It is possible to change the polarity 

in the Settings menu under the heading I/O Polarities (“Error detect”). 

An external voltage connected to “HF-DA-Error” can, of course, also be 

switched through here (max. 24 V/100 mA). 

7.) Signal “FAN-ON” DSUB PIN 12 

At this output, there is a control voltage (12 Volt) for monitoring the fan function 

when the internal fan is running. 

8.) Signal “FS-24Volt” DSUB PIN 13 

Switching on the generator (Ultrasound On) by connecting a voltage between 15 – 24 Volt 

between PIN 13 and GND (PIN 4/15) 

9.) Signal “FS-GND” DSUB PIN 14 

Switching on the generator (ultrasound ON) with a relay contact or switch by connecting 

PIN 14 on the DSUB socket to GND (PIN 4 /15). 

10.) Signal “ Nominal” DSUB PIN 11 

Not used in this version. Please keep the PIN free. 

11.) Signal “GND” DSUB PIN 4, 15 

The GND signal is available on multiple pins of the DSUB socket. 

It is the common reference point for all input and output signals.

the test button). 

The LCD display 

Various screens and functions are available in the LCD display: 

1. Power output indicator in “Watts” 

The current power output is displayed. After switching off the device, 

the maximum power output reached is saved until the next time the 

device is switched on. 

2. Output setting 

Here, the “Select” encoder can be used to set the desired power output to between 

50% and 100% of the nominal generator amplitude. The desired amplitude is set 

by pressing and then turning the encoder. Pressing the encoder again applies 

the selected amplitude. 

3. Timer function 

A time of up to 180 minutes can be set by pressing the encoder. This time starts running 

when the generator is switched on, either via the interface or the test button. No error 

message is displayed when the time expires. When the generator is switched on using 

the test button and the time expires, the generator switches off and remains in this 

state until it is switched on again. The end of the expired time can be determined via 

the interface by requesting the “HF-DA” signal. If an “OFF” time is also set, the generator 

switches on and off continuously. 

4. Contrast setting 

The contrast of the LCD display can be adjusted by pressing and turning the encoder. 

Pressing the encoder again applies the set value. Set the contrast in such a way that the 

LCD display can be easily read. 

14


5. Display backlight 

The display‘s backlight can be turned on and off by pressing 

and turning the encoder. For optimum readability, we recommend 

turning the backlight on. 

6. Settings 

You can access the Settings menu by entering the password “6354”. 

This is also done by turning the encoder. After selecting the correct number 

each time, confirm by pressing the encoder. 


Functions in the Settings menu 

Controll Assignment 

Here you can set how the generator is to be controlled. 

Internal Front means control via the front control panel, Front & ext. Voltage 

means that the generator can also be operated via an external voltage 

(see pin assignment of the interface) and RS232 means that the generator 

can be controlled via the RS232 interface (available as an option). 

Frequency Range 

You can set the frequency range of the generator here. 

The preset frequency range depends on the frequency 

of the transducer system. 

Recommendation: Do not change the factory settings. 

I/O POLARITIES 

Remote IN: 

Symbol “H”: 

Symbol “L”: 

Error out: 



The polarity of the remote control input 

can be altered by changing this value. 

Factory default settings: 

A closed contact switches the generator on. 

When the contact is closed, the generator is switched on. 

When the contact is open, the generator is switched on. 

The polarity of the internal error relay can be switched over 

by altering this value. 

Factory default settings: 

Closed contact is an error. The polarity of the internal error relay 

can be switched over by altering this value. 

Closed contact is an error. 

Opened contact is an error. 

If the polarity is altered in such a way that a closed contact reports an error, you should be aware 

that the contact is open when there is no mains voltage at the generator or if the generator displays 

complete failure. 

RF detect: 



The status signal HF-DA (generator is emitting HF voltage) 

can be altered by changing this value. 

Closed contact – generator emits HF voltage. 

Open contact – generator emits HF voltage. 

Please note that when the generator is not connected to the mains or there is a complete failure, 

this contact is open. 

Recommendation: Do not change the factory settings.

Error messages and troubleshooting 

The following error messages may appear in the display: 

A – PROTECTION ACTIVE 

The electronic overcurrent fuse has detected an error 


Possible causes: 

Remedy: 

Transducer is defective 

Power supply or plug is defective 

Unscrew the transducer connection on the housing 

Switch on the generator without the transducer connected 

a.) Error message still displayed: 

Generator is defective 

b.) Error message no longer displayed: 

Check the transducer and power supply 

NO RF – DETECTED 

The electronic overload/short-circuit fuse has detected an error. 

No output voltage. 

Causes and remedy: see “A-PROTECTION ACTIVE” 

The monitoring device in the generator detects all malfunctions occurring during 

operation, except the highly unlikely event of a single transducer element becoming 

detached from the transducer membrane. This could lead to a drop 

in the ultrasonic output in the near field, i.e directly on the membrane. 

OVER TEMPERATURE 

The generator is too hot 

Possible causes: 

Remedy: 

• The generator‘s ventilation slits are blocked 

• Unsuitable location for the generator 

• The transducer is defective 

• The fan is defective 

• Check the fan! When the mains power is switched on, the 

fan should briefly start running 

• Check the air flow to and from the generator 

• Check the transducers

Notes on our transducer systems: 

Please also observe the safety instructions! 

Maximum cable length: 15 meters 

Special lengths can be used following consultation with our Sales Department. 


Cleaning medium: 

Viscous media with a dynamic viscosity of >1000 mPAs at room temperature may not be used. 

Bending radius of the stainless steel hose: 

The minimum bending radius of the stainless steel hose is 32 mm. Tighter radiuses will irreparably 

damage the stainless steel hose. 

Minimum distances (spacing) of the transducer system: 

Minimum distance to the surface of the liquid: 50 mm 

Minimum distance to heating elements: 50 mm 

Minimum distance between two facing transducers: 200 mm 

The surface of the transducer must be treated with care. Scratches accelerate the appearance of pitting 

corrosion and shorten the service life. 

Special notes on rod-style transducers: 

Rod-style transducers made of titanium alloy are not resistant to hydroxides or inorganic acids and their salts. 

Temperature resistance: HD series: up to 95°C 

Non-HD models: up to 85°C 

Maximum pressure: 10 bar 

Rod-style transducers should never be operated dry. 

Should they repeatedly be operated dry at short intervals, this can damage the transducers irreparably. 

Special notes on submersible transducers: 

The inside of the transducer must be protected from moisture. The transducer must be attached to the mounting 

fixtures provided. No additional boreholes may be drilled, as this can lead to irreparable damage and also 

invalidates the warranty. 

Maximum pressure: 0.3 bar 

Maximum negative pressure: 0.1 bar 

The liquid in which the transducers are located may only contain chemicals that do not attack stainless steel 1.4571. The maximum 

chloride content of this liquid may not exceed 40 ppm, as pitting corrosion may otherwise occur. 

Should you have other corrosion protection requirements, please get in touch with our Sales Department.
