level
The parameters stored in the LME7 can be displayed or changed at parameter level.
The change to the parameter level requires entry of a password.
Siemens supplies the LME7 with the factory settings according to
Type summary
.
The OEM can change the Siemens factory settings to match its own requirements.
With the LME7, the burner control’s characteristics are determined primarily through
parameterization. Every time the unit is recommissioned, the parameter settings must
be checked. The LME7 must never be transferred from one plant to another without
matching the parameters to the new plant.
Caution!
Parameters and settings may only be changed by
qualified personnel
.
If parameters are changed, responsibility for the new parameter settings is assumed by
the person who – in accordance with the access rights – has made parameter changes
on the respective access level.
After parameterization, the OEM must check to ensure that safe burner operation will
be warranted.
The OEM which made the settings is always responsible for the parameters, their
settings and compliance of the respective application with the relevant national and
international standards and safety regulations, such as EN 676, EN 267, EN 1643,
EN 746-2 etc.
Siemens, its suppliers and other Group Companies of Siemens AG do not assume
responsibility for special or indirect damage, consequential damage, other damage, or
damage resulting from wrong parameterization.
Warning!
If the factory settings are changed, all changes made must be documented and
checked by the OEM.
The OEM is obliged to mark the LME7 accordingly and include at least the list of unit
parameters and settings in the burner documentation.
Siemens also recommends attaching an additional mark on the LME7 in the form of an
adhesive label. According to EN 298, the label should be easy to read and wipeproof.
The label with a maximum size of 50 mm x 40 mm can be attached to the upper part of
the housing.
Example of label:
OEM logo
Type / part no.: 1234567890ABCD
