Notice
Certified balances and balances used for legal applications have the EU type approval. The year of the initial verification is
shown next to the CE mark. Such balances are verified in the factory and carry the „M“ mark on the actual balance. The
year of initial verification is shown next to the CE mark. The GEO value of verified balances explains for which location of
use the balance has been verified. This GEO value is shown on the balance itself and on the packing. Further details see
GEO value table.
Hinweise
Für geeichte/eichpflichtige Waagen liegt eine EU Bauartzulassung vor. Das Jahr der ersten Eichung ist neben dem CE
Zeichen aufgeführt. Solche Waagen sind ab Werk geeicht und tragen die Kennzeichnung „M“ auf dem Gerät. Der GEO-
Wert gibt bei vom Hersteller geeichten Waagen an, für welchen Aufstellungsort die Waage geeicht ist. Dieser GEO-Wert
befindet sich auf der Waage sowie der Verpackung. Genaueres ist der GEO-Wert-Tabelle zu entnehmen.
Remarques
Il existe une homologation UE pour les balances étalonnées/soumises à l´obligation d´étalonnage. L’année du premier
étalonnage est indiquée à côté de la marque CE. Ces balances sont vérifiées à la sortie d´usine et portent la marque „M“
sur l’appareil lui-même. Dans le cas des balances étalonnées par le fabricant, la valeur GEO indique le lieu d’utilisation
pour lequel la balance été étalonnée. Cette valeur GEO se trouve sur la balance ainsi que sur l’emballage. Vous trouverez
plus de détails dans le tableau de valeurs GEO.
Notas
Las balanzas verificadas/verificables cuentan con una aprobación de modelo UE. El año de la primera verificación está
indicado al lado del distintivo CE. Estas balanzas están verificadas en fábrica y llevan la designación „M“ sobre el propio
aparato. El valor GEO indica el lugar de ubicación por lo cual la balanza está verificado. El valor se encuentra sobre la
balanza así como sobre el embalaje. Por favor toman demás detalles de la tabla GEO.
Avvertenza
Per le bilance sottoposte/sottoponibili a verifica esiste un’approvazione CE del tipo. L’anno della verifica prima è riportato a
fianco del contrassegno CE. Queste bilance sono sottoposte a verifica in fabbrica e sono marcate con contrassegno ”M“. Il
valore GEO nelle bilance verificate in fabbrica indica il luogo d’impiego per il quale la bilancia è stata verificata. Questo
valore GEO è riportato sulla bilancia e sull’imballo. Ulteriori dettagli si possono ricavare dalla tabella “valori GEO”.

influences such as sea water and unsuitable cleaning material are also excluded
from warranty.

FIS-BA-def-0411 67
When installing the equipment or changing equipment settings, always
carry out a test run with the known test weight at cyclic intervals. This avoids
incorrect results and evaluations.
Ensure that only trained personnel operate and take care of the equipment.
Please check that our products are handled appropriately.
Our products are regularly subjected to further development and are governed by
various regulations specific to the country. Illustrations and graphics used in the
operating instructions may differ from the model supplied.
3.3 Safety information
The equipment may only be opened by trained service engineers in compliance
with KERN directives.
Please disconnect the equipment from the mains before opening.
Warranty is forfeited if the equipment is opened.
The FIS weighing system may not be used in hazardous areas.
3.4 Important information
The measured values are stabilised by a short warm-up period lasting a few
minutes after switching on. Apply the items to be weighed carefully. Do not place
a permanent load on the weighing plate. Be sure to avoid knocks and
overloading in excess of the maximum load (max.), as this can cause damage to
the balance.
Switch the balance off for a short period of time following a disturbance in
programme sequence. The weighing process must now be repeated.
Check the balance regularly using external test weights.
Guarantee/warranty are forfeited if the balance is opened and following use
of the balance outside the prescribed directives.
Keep the packaging in case if should be necessary to return the equipment. Only
use the original packaging to return the equipment.

4 Installation and commissioning, operating instructions
4.1 Conditions applicable to the place of installation
- Level installation surface
- It must be ensured that the location is free from vibrations and that
installation is carried out in as dry an area as possible that is not subjected
to drafts.
- Arrange the equipment in such a way as to facilitate operation, working
procedures and service.
- As far as systems subjected to compulsory calibration are concerned, the
person weighing must have an unobstructed view from the evaluation
equipment to the place of weighing.
The weighing system is not suitable for the following environmental areas:
- Potentially explosive areas
- Areas subjected to vibrations and jarring
- External temperature ranges with temperatures below -10°C or
above +40°C
4.2 Installation of the weighing system
Unpack the weighing system carefully at the place of installation paying special
attention to the connecting cables.
Weighing belts or roller conveyor tracks may only be installed on the load carrier
after consulting with KERN.
Moving parts must not be able to re-charge.
Power-driven weighing belts or roller conveyor tracks must comply with the
requirements of the 98/37/EC directive on machinery.
4.3 Function test/ready-to-operate
An automatic function test is carried out as soon as the FIS is connected to the
mains supply.
The weighing terminal is operative when a weight value is displayed.
Maximum weighing accuracy is reached following a short warm-up period.
It is favourable to leave the weighing terminal connected to the mains voltage
for the entire working day.
A consistent operating temperature and highest possible balance accuracy are
achieved in this way.
Please be sure to observe chapter 13 on calibration (CAL).

4.4 Scope of delivery
The weighing system is supplied with the following components:
- Load carriers
- FIS weighing terminal
- Operating instructions
4.5 Levelling the weighing system
The weighing system is levelled in the factory using the foot screws. Please
check that all 4 foot screws rest evenly on the supporting area.
The bubble level may also be installed underneath the load plate on small load
carriers.
Please compensate for any unevenness by adjusting the foot screws.
4.6 Mains connection
A separate mains switch is not available.
Maximum weighing accuracy is reached following a short warm-up period. It is
favourable to leave the weighing terminal connected to the mains voltage for
the entire working day.
A consistent operating temperature and highest possible balance accuracy are
achieved in this way.
4.7 Power supply
4.7.1 Installation of the power supply by the customer
Installation of the power supply for the connection of our equipment must be
carried out in compliance with the international standards and the regulations
deriving from these. They mainly include the recommendations of at least
one of the following commissions:
- International Electrotechnical Commission (IEC)
- European Committee for Electrotechnical Standardisation (CENELEC)
- Association of German Electrical Engineers (VDE)
Our equipment is designed according to VDE protection class III (protective low
voltage ).

5 Calibration Information
Weight symbol flashing:
Calibration switch (hardware seal) is not in secured condition.
Calibration switch (=equalising plug)
Traditionally, backup of the data relevant to calibration is carried out by means of
hardware backup (equalising plug on the circuit board in the terminal).
Equalising plug

Status
Plug not inserted Calibration data not saved
Plug inserted Calibration data saved
The calibration switch (equalising plug) can be seen through the right-hand window
on the terminal. This switch is secured by means of a sticker (stamp) when in
calibrated condition.
Balance calibration is not valid without the valid sticker.
The four screws on the rear side of the terminal must be opened in order to reach
the calibration switch (equalising plug).
Caution: Please remove the mains plug before opening the terminal.
The GEO value can only be changed or the balance calibrated if the calibration
switch (equalising plug) has been pulled out.

Position of the security mark above the calibration switch (equalising plug)
Balances that are subject to compulsory calibration must be taken out of
operation if:
- The weighing result of the balance is outside the error limit. Therefore,
apply a known test weight (approx. 1/3 of the nominal load) to the balance at
regular intervals and compare with the display value.
- The recalibration deadline has been exceeded.

5.1.1 Information on recalibration
A balance is recalibrated according to the legal requirements applicable to the
individual countries. For instance, the calibration validity period for balances in
Germany is normally 2 years. The period of time for calibration validity begins
when the balance is put into operation (installation and commissioning). Also see
the identification plate (2002 in the preceding example as designated CE 2002).
5.1.2 Calibration information for non EU countries
The statutory provisions of the relevant countries are to be observed.
5.1.3 Levelling device
The FIS is fitted with a bubble level. This must be checked following every
change in location and the balance re-levelled if necessary.
The bubble level may also be installed underneath the load plate on small load
carriers.
