1.Preface
Dear users,
Thank you for using SONIC ultrasonic systems, a smart, digital control ultrasonic power
supply developed by our company.
Before using this product, please read this manual carefully and be familiar with the
operation regulations and parameter scopes.
Only Professional technicians or trained personnel can commission or maintain this
product.
2.Precautions:
Please read this manual in details before operation to guarantee a smooth operation and
self-safety.
Only professional personnel is allowed to install this system. Operators must be trained
before work.
Protection measures have to be taken for operation in hazardous environment. As some
energy will be transformed into heat during the operation, be cautious that the
accumulation of heat will lead to explosion or burning without any protection.
Peripheral electric device electromagnetic compatibility must meet the requirement of
the related country. All the operation parameters can be set by user, but the parameters
protected by passwords shall be kept at factory default parameters. For any support,
please contact our technical personnel. It is strictly prohibited to turn on the machine
with a loose welding horn.
When moving or maintaining the device, it has to be handled by professional personnel
under condition when power is off.
For repairing or maintaining the generators dust has to be removed by compressed air
blower or brush. Please don’t use cleansing reagent to clean the case or LCM interface.
Cloth with slight water can be used for rubbing the dirt.
High-load driving cables can control or signal monitoring cables shall be screened
stranded conductors. Please don’t install it close to high-current devices. The screened
cables shall be connected to power supply grounded line. All the driving cables can
control cables shall be grounded, and the generator’s ground line shall be connected to
the ground line of power supply.
Pay more attention to the malfunction codes on the generator to facilitate early action to
prevent expansion of the malfunction.

The generator shall be installed in correct direction to assure firmness without loosening.
Power supply specs must meet the demand of the generator.
Select generators as per the load specs (such as frequency, power, etc. ). On-load high
frequency driving cables and the temperature sensor cables shall not be too long, and
shall not be rolled up, otherwise the temperature will go up to affect the accuracy.
Professional personnel shall be in charge of the repair or maintenance if any of following
happens:
After turning off the power:
When any liquid or metal or conductive material goes into the generator;
When cable connection is loose or damaged;
When the power supply is installed loose;
When the displayed contents is obviously different from normal conditions.
Attention: Please do the maintenance with prior agreement of chief technician.

3.Installation Place
The generator will produce heat during work, over-heat will lead to over-heat protection (see
details in “Over-heat malfunction”, so we used strong cooling system. The distance between
generator vent port and other obstacles shall be kept in 10cm. The temperature shall not exceed
40℃and moisture shall be exceed 75%.
Please do not make metal or vapor go into the generator case. Long time exposure to the
chemicals will damage the electronic elements in the generator.
4.Power Supply
Input: AC 220V, 50/60Hz.
Grounded 3-core cables shall be used to connect with generator.
Power supply fuse is inside the generator. When it is needed to replace the fuse, the generator
case has to be opened.
Attention: Input power has to be cut off when replace fuse. Please use the fuse with same specs
to replace the damaged one. See “Power Supply Specs”.
