3 Basic instructions
3.1 Documentation
These installation instructions contain all data necessary for placing and
commissioning the weighing bridges KERN KKP V40M.
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 balance you purchased is intended to determine the weighing value of material
to be weighed. 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.

KKP_V40-IA-e-1811 4
3.3 Improper Use
Do not leave permanent load on the weighing bridge. This may damage the
measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
bridge, minus a possibly existing tare load, must be strictly avoided. This could cause
damage to the weighing bridge.
Never operate in an explosive environment. The serial version is not explosion
protected.
The structure of the weighing bridge may not be modified. This may lead to incorrect
weighing results, safety-related faults and destruction of the balance.
The weighing bridge 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.

6 Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The weighing bridges 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 at the installation site must be able to carry safely the weight of the
maximally loaded weighing bridge at the resting points. At the same time it
should be sufficiently stable, that no vibrations may occur during weighing
work.
•In the installation site possibly no vibrations, e.g. by neighbouring machines
should occur.
•Do not use the weighing bridge in an explosive environment.
•Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight.
•Protect the weighing bridge against direct draughts e.g. due to open windows
and doors.
•Use weighing bridge only in dry environment, protect it against high humidity,
vapours and dust.
•Do not expose the device to extreme dampness for longer periods of time.
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 goods to be weighed or 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.
•Major display deviations (incorrect weighing results) may be experienced
should electromagnetic fields (e.g. due to mobile phones or radio equipment),
static electricity accumulations or instable power supply occur. Change
location or remove source of interference.

7 KKP_V40-IA-e-1811
6.2 Unpacking, Scope of delivery
+Danger for the back!
The weighing bridge is relatively heavy. Always use a suitable
lifting device to lift it out of the packaging or to transport it to
the required installation site.
+Do not step under the suspended load, risk of injury!
Scope of delivery:
•Weighing bridge with assembled connection cable
•4 weighing cell feet
•Operating manual
Ensure that the contents of package is complete.
According to the version, for assembling the weighing bridge the following accessories
(optional) must be available:
(A) 2 access ramps
or
(B ) 1 access ramp and 1 foot plate set
or
(C) 2 foot plate sets

KKP_V40-IA-e-1811 8
6.3 Assembly, levelling
Accurate weighing results require a weighing bridge with perfect horizontal
alignment. During initial installation and after each change of work area it is
necessary to level the weighing bridge.
Placing the weighing bridge:
1. Prior to the final placing, install the four weighing cell feet.
2. Place the weighing bridge equally on the installation site and check if it is in an
even position and all four feet are in contact with the floor. Level the weighing
bridge by turning the weighing cell feet. For this purpose use an external levelling
appliance, e.g. a water level.
3. Ensure that the connecting cable is not damaged or squeezed during lifting and
placing.
Placing the weighing bridge with access ramps and/or foot plates:
Prior to step 2 (see Placing the weighing bridge) mark and fix the position of the
ramps or the foot plates.
Place the weighing bridge equally on the installation site. In the area of the
installation site of the weighing bridge, especially in the area of the weighing cell
feet, observe the evenness and the horizontal alignment of the foot plates and
ramps. Compensate minor height differences with the help of the adjustable
weighing cell feet. For this purpose use an external levelling appliance, e.g. a
water level.
Ensure that the connecting cable is not damaged or squeezed during lifting and
placing.
+The weighing bridge must be aligned with the help of a water
level.
+All setting feet must rest equally.
Verified weighing systems:
In case of verified weighing systems the weighing bridge must be firmly
fixed on the floor. This is essential for the reproducibility of the measuring
results. Optionally using two access ramps or two pairs of foot plates or a
combination of both.

9 KKP_V40-IA-e-1811
6.5 Cleaning
For cleaning or maintenance of the floor balance the weighing plate can be opened
by two retractable hand grips easily and without health risk for the back. (s. fig.)
6.6 Connecting a display unit
Attention
Put the connecting cable to the display unit in a manner that it is protected against
damage.

7.2 Operation with access ramps
•The load plate of the weighing bridge is an active weighing element, the access
ramps are passive, i.e. during the weighing process all wheels of the conveying
vehicles must rest on the load plate.
•The air gap between the load plate and the access ramps must be free. Especially
for weighing of grainy or small-piece weighing goods, the gap should be controlled
regularly and kept clear.
7.3 Load/unload weighing bridge
•Place the load on the scales using a lifting truck, a crane or a forklift truck. Ensure
that the load is not swinging when it is placed onto the scales.
•Lift the load first vertically at least 10 cm above the scales before it is removed or
newly placed.

9.2 Check and adjustment of the corner load
Check of the corner load:
•Place the test weights in the centre of the load plate
and tare.
•The balance displays -0-.
•Place the test weights successively on all four
corners.
•Now the deviations are displayed with sign, write
down the values. If there are deviations out of the
tolerances (see chap. 9.1), an adjustment will be
necessary.
Adjustment of corner load:
Preparation:
•For a better control of the modifications which occur
during adjustment, select in the configuration menu
the highest readability for control purposes.
•Open connection box
Adjustment rule:
The corner (weighing cell) with the biggest negative
deviation must be set to zero. Do not re-
adjust this corner
even after several adjustment sequences.
