1.6 Setting and parameter setting notes
•
When adjusting the electronic fuel / air ratio control system integrated in the
LMV5..., allow for sufficient amounts of excess air since – over a period of time –
the flue gas settings will be affected by a number of factors (e.g. density of air,
wear of the actuating devices, etc.). For this reason, the flue gas values initially set
must be checked at regular intervals
•
To provide protection against inadvertent or unauthorized parameter transmission
between the parameter backup memory of the AZL5... display and operating unit
and the LMV5... basic unit, the OEM ¹) must enter an individual burner identification
(ID) for each burner. Compliance with this regulation is mandatory to ensure that
the LMV5... system will prevent parameter sets from other plant (with unsuited and
possibly dangerous parameter values) to be transmitted to the LMV5... basic unit
via the backup memory of the AZL5... (also refer to the description of burner
identification in chapter 7 Display and operating unit AZL5...)
¹) OEM = burner or boiler manufacturer
•
With the LMV5..., it is to be noted that the unit's characteristics are determined
primarily by the specific parameter settings rather than by the type of unit. This
means that, among other things, each time a plant is commissioned, the parameter
settings must be checked and the LMV5... may not be transferred from one plant to
another without adapting the parameter settings to the new plant
•
In the case of dual-fuel burners and oil-firing, the short preignition (Phase 38)
parameter OnTmeOilIgnition is to be selected and a magnetic clutch is to be used,
thus ensuring that there will be no oil pressure until this phase is reached. Then,
the long preignition (from Phase 22) must be parameterized
•
When using the ACS450 PC software, the safety notes given in the relevant
Operating Instructions (CC1J7550) must also be observed
•
A password protects the parameter setting level against unauthorized access. The
OEM allocates individual passwords to the setting levels he can access. The
standard passwords used by Siemens Landis & Staefa must be changed by the
OEM. These passwords are confidential and may only be passed on to persons
authorized to access such setting levels
•
The responsibility for setting the parameters lies with the person who – in
accordance with his access rights – has made changes to the respective setting
level
In particular, the OEM will assume responsibility for the correct parameter
settings in compliance with the standards covering the specific applications (e.g.
EN 676, EN 267, EN 1643, etc.).
