Parameterization
Siemens supplies the LME39… burner controls with the factory settings as specified in
«Type summary».
The OEM can change the Siemens default settings to meet its own requirements.
With the LME39…, the burner control’s characteristics are determined primarily through
parameterization. Every time the unit is recommissioned, the parameter settings must be
checked. The LME39… 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 staff
.
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 set-
tings and compliance of the respective application with the relevant national and inter-
national standards and safety regulations, such as EN 676, EN 267, EN 1643, etc.
Siemens, its suppliers and other Group Companies of Siemens Ltd. 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 unit accordingly and to include at least the list of device
parameters and settings in the burner’s documentation.
Siemens also recommends attaching an additional mark on the LME39… in the form of
an adhesive label. As specified in EN 298, the label should be easy to read and wipe
proof.
The label with a maximum size of 70 x 45 mm can be attached to the upper part of the
housing.
Example of label:
