3 Basic Information (General)
3.1 Documentation
These installation instruction contain all data necessary for placing and
commissioning the weighing beams KERN KFA V20.
In combination with a display unit, described below as weighing system, for operation
configuration, please refer to the operating instructions of the display unit.
3.2 Proper use
The weighing beams are designed for weighing of large, voluminous or long loads.
They are designed to be used as “non-automatic scales“ As soon as a stable
weighing value is reached the weighing value can be read.
3.3 Improper Use
Do not leave loads permanently on the weighing beams. This may damage the
measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
beams, minus a possibly existing tare load, must be strictly avoided. This may
damage the weighing beams.
Never operate in an explosive environment. The serial version is not explosion
protected.
Do not modify the construction of the weighing beams. This may lead to incorrect
weighing results, safety-related faults and destruction of the weighing beams.
The weighing beams may only be used according to the described conditions. Other
areas of use must be released by KERN in writing.
3.4 Warranty
Warranty claims shall be voided in case
• Our conditions in the operation manual are ignored
• The appliance is used outside the described uses
• Structural changes of the device
• Mechanical damage and damage caused by media, liquids
• Natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• Overload of the measuring system

3.5 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
weighing system and, if applicable, the testing weight, must be checked regularly.
The responsible user must define a suitable interval as well as type and scope of this
test. Information is available on KERN’s home page (www.kern-sohn.com with
regard to the monitoring of weighing system test substances and the test weights
required for this. In KERN's accredited DKD calibration laboratory test weights and
weighing systems may be calibrated (return to the national standard) fast and at
moderate cost.
4 Basic Safety Precautions
4.1 Pay attention to the instructions in the Operation Ma nual
Carefully read this operation manual before setup and commissioning,
even if you are already familiar with KERN balances.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
The installation of a display unit must only be carried out by a well acquainted
specialist with the workings of weighing balances.
5 Transport and stora ge
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly
required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.
