INTRODUCTION

Dear Customer,

Thank you for your purchase of the product.

This ultrasonic SONOWELD-generator has been developed using the latest technologies to allow for greater

overall performance and stability.

Please read and follow these operating instructions carefully before installing or commissioning your

product. As with any electrically powered device, failure to observe these instructions can present a risk to

life.

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. Failure to comply with this will result in a loss of warranty rights.

General information

This ultrasonic generator is a device which is used for ultrasonic plastic- and metal-welding applications as well

as for different special applications such as: Sieving, atomizing, etc.

The main features are:

Autotuning circuit to tune automatically to the resonant frequency of the connected horn.

Fully digital frequency generation.

High speed microcontroller to control all functions of the generator.

LCD-display with rotary encoder

Modbus on all generators

Constant / adjustable amplitude 0 –100 %

Protected against : Short circuit

Overtemperature

Overload

SAFETY INSTRUCTIONS

Symbols in manual:

Immediate imminent danger –health and live

(bad injuries or dead)

hot surface.

Do not Touch!

Possible damage,

without danger for people

Electrical voltage!

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!

This 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.

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. Please see the last page.

Inspection or diagnostic 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 main power source. (unplug

the mains connection).

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.

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 provided on the device itself.

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

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

INSTALLATION & ENVIRONMENT

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

The selected location for the device should be in an area where ambient temperatures do not exceed 40°C.

If the generator cannot dissipate the heat sufficiently, it will display an error message due to excess

temperature (see also the “OVER TEMPERATURE” error description).

Power supply

The ultrasonic generator draws its power (210-250VAC/50-80Hz) via the connection cable with Power socket.

It has an internal main fuse (10 AF).

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

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

vapours from penetrating the device. Ambient temperatures of over 30°C should

be avoided.

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

the device being irreparably damaged.

•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.

•Only use cables with sufficient cross-section.

•Minimum cross-section: 1.5 mm2.

HF connector

HF OUTPUT

HF connector is Lemo connector

Can be modified according to

customer request.

•Output voltage could be between 600V and 1200V AC.

•Only use cables specified by the manufacturer.

•Use only shielded transducer connection cables.
