Parameter Settings
The parameter level can be accessed by turning to the ’Parameter’ selector switch position.
When working on level 1 ... 4, this works only with the burner stationary (i.e. no signal on the
digital inputs). Only level 0 is accessible with the burner running.
NOTICE
As a rule, the factory parameter settings are precisely tuned for the installation for which the
unit has been designed. Therefore, it is only necessary to change parameter settings in ex-
ceptional cases.
4.3.2
Access Levels
The parameters are divided into four different access levels according to function and safety
classification:
•
Operating level (Level 0)
Accessible without password, non-critical parameters that may possibly have to be altered
during operation.
•
Customer level (Level 1)
Accessible with modifiable password (on delivery set at ’0000’), access to parameters, ad-
justment of which calls for technical knowledge, which are tailored to the system and
which are not altered during operation.
•
Service level (Level 2)
Accessible with a fixed password, but only to personnel specially trained in parameterisa-
tion. Access to all parameters that are not fixed on the basis of standards and technical
regulations.
•
Production levels (Level 3 and 4)
Access to all parameters (only possible through LAMTEC)
Each parameter level is protected by its own checksum. This checksum serves to show that
no changes have been made.
