3 Basic Information (General)
3.1 Documentation
These installation instructions contain all data necessary for placing and
commissioning the platform KERN TKFP V30-A.
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 platform purchased by you is intended to define the weighing value of weighed
goods. It is intended to be used as a “non-automatic balance”, i.e. the material to be
weighed is manually and carefully placed in the centre of the weighing pan. As soon
as a stable weighing value is reached, the weighing value can be read.
3.3 Improper Use
•Our balances are non-automatic balances, not provided for the use in dynamic
weighing processes. However, the balances can also be used for dynamic weighing
processes after verifying their individual operative range, and here especially the
accuracy requirements of the application.
•Do not leave permanent load on the weighing pan. This can damage the measuring
mechanism.
•Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. The weighing
system could be damaged.
•Never operate the weighing system in explosive environment. The serial version is
not explosion protected.
•Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the balance.
•The weighing system unit may only be operated in accordance with the described
default settings. 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 beyond the described intended use
•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.
6 TKFP-V30-A-IA-e-2312
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 Manual
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 staff.
The installation and maintenance must only be carried out by a well acquainted
specialist with the workings of weighing balances.
5 Transport and storage
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.
Reattach possibly supplied transport securing devices.
Secure all parts against shifting and damage.

6 Unpacking, Installation and Commissioning
6.1 Installation Site, Location of Use
The platforms are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast if you select the right location for your weighing
system.
On the installation site observe the following:
•Place the weighing system on a firm, level surface. The floor must be able to
carry safely the weight of the maximally loaded platform at the resting points. At
the same time it should be sufficiently stable, that no vibrations may occur during
weighing work. This is to be considered too when the platform is installed in
conveyor systems and similar.
•In the installation site possibly no vibrations, e.g. by neighbouring machines
should occur.
•Do not use the weighing system in an explosive environment.
•Avoid extreme heat as well as temperature fluctuation e.g. caused by installing
next to a radiator or in the direct sunlight.
•Protect the weighing system against direct draughts e.g. due to open windows
and doors.
•Use weighing system only in dry environment, protect it against high humidity,
vapours and dust.
•The platform must have been stabilized to room temperature, before power
supply is switched on.
•Do not expose the appliance to heavy moisture over a longer time period. Non-
permitted condensation (condensation of air humidity on the appliance) may
occur if a cold appliance is taken to a considerably warmer environment. In this
case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
•Avoid jarring during weighing.
•Avoid static charge of weighed goods and weighing container.
•Keep away chemicals (such as liquids or gasses), which could attack and
damage the balance inside or from outside.
•Keep IP protection of the device.
•If electromagnetic fields (e.g. by mobile phones or radio equipment), static
charges (e.g. when weighing or countings plastic parts), as well as instable
current supply occur, the displayed indications may differ considerably (wrong
weighing results, damage to the balance). Change location or remove source of
interference.

6.2 Unpacking, Scope of delivery
Remove the underconstruction and the weighing plate from the package, remove
packaging material and place the devices at the planned workplace. Check if all parts
of the scope of delivery are present and free of damage.
Scope of delivery:
•Underconstruction (lacquered steel)
•Weighing pan (stainless steel)
•Transport securing (depending on model, see chap. 2)
•Installation Instructions
6.3 Placing
1. Remove transport securing (see chap. 6.3.1).
2. Put the weighing plate on the underconstruction.

6.3.1 Transport Securing
General hints for transport securing
•Please consult the Technical Data whether your balance is equipped
with a transport securing, chap. 2.
•There are different types of transport securings in KERN balances.
Please see the indications explained in this chapter.
•Never remove other screws than these for the transport securing as
otherwise the balance could be damaged.
•The sealed screws (1) must not be unscrewed. The sealed screws
can be recognized by the sealing varnish (different colours).
•Do not remove the off-centre load attachments (2) as otherwise the
balance could be damaged. The off-centre load attachments are
located between the upper and the lower part of the platform. They
consist of a screw and a nut.

Variant 1:
Note on transport securing
Type of transport securing
•1 x hexagon screw on the upper side
with nut
•1 x threaded pin with inner hexagon on
the lower side with nut
1. Remove the weighing plate.
2. Turn the scale over so that the bottom is facing you.
3. The position of the transport securings is marked by an arrow.
4. Remove the nuts of the transport securings on the lower side.
5. Remove the threaded pin on the lower side.
6. Turn the balance over so that the top is facing you.
