Parameter level
:
The parameters stored in the basic unit can be displayed or changed on the parameter
level. The change to the parameter level requires entry of a password.
Siemens supplies the burner control LMO39… with the factory settings according to
Type summary
.
The OEM can change the Siemens default settings to meet its own requirements.
With the LMO39…, the burner control’s characteristics are determined primarily through
parameterization. Every time the unit is recommissioned, the parameter settings must
be checked. The LMO39… 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
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. If this is not observed, there is a risk of loss of safety functions.
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 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 LMO39… 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:
