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 GEO­Wert 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”.

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.

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.
