5.4

Compatibility of modules

In case of composition of modules, WELMEC 2 (Issue 5) 2009, paragraph 11 shall be satisfied.
6.

Special conditions for verification

6.1

Composition of modules

The environmental conditions should be taken into consideration by the composition of modules for a
complete weighing instrument, for example instruments with load receptors placed outdoors and hav-
ing no special protection against the weather.
The composition of modules shall agree with section 5.4.
An example of a declaration of conformity document is shown in section 10.
7.

Securing and location of seals and verification marks

7.1

Securing and sealing

Seals shall bear the verification mark of a notified body or alternative mark of the manufacturer ac-
cording to ANNEX II, section 2.3 of the Directive 2009/23/EC.
7.1.1 Indicator
Access to the configuration and calibration facility requires that a calibration jumper is installed on the
main board.
Sealing of the cover of the enclosure - to prevent access to the calibration jumper and to secure the
electronics against dismantling/adjustment - is accomplished with a brittle plastic sticker. The sticker
is placed so access to one of the screws of the enclosure is prohibited (see figure 3, 4 & 5).
7.1.2 Indicator - load cell connector - load receptor
Securing of the indicator, load receptor and load cell combined is done in one of the following ways:
•
Sealing of the load cell connector with the indicator by a lead wire seal
•
Inserting the serial number of the load receptor as part of the principal inscriptions contained on the
indicator identification label
•
The load receptor bears the serial number of the indicator on its data plate.
7.1.3 Peripheral interfaces
All peripheral interfaces are "protective"; they neither allow manipulation with weighing data or legal
setup, nor change of the performance of the weighing instrument in any way that would alter the legal-
ity of the weighing.
7.2

Verification marks

7.2.1 Indicator
A green M-sticker shall be placed next to the CE mark on the inscription plate.
The sticker with verification marks may be placed on or next to the inscription plate or on the front of
the indicator.
