NOTICE
Whenever CO control malfunctions, you can switch smoothly to O
2
trim. That means you have
to set and activate both CO control and O
2
trim (see Chapters 8.9.1 Activating CO/O2 Control
Activating CO Control).
You need access level 1 for this purpose.
Factory setting:
CO control is an adaptive optimisation of the electronic ratio control. Control parameters and
setpoint values do not have to be set.

8.9.2 Access Levels
The parameters are subdivided into four different access levels depending on their function or
security classification:
Operating level (level 0)
No password required. Parameters which are not security-related and that can be changed
during operation.
Commissioning level (level 1)
Accessible using a password which can be changed. Access to parameters which require spe-
cialist knowledge, are set for the specific system and cannot be changed during operation.
Factory setting = 0000
Service level (level 2)
Accessible with a fixed password but only to personnel specifically trained in parameter as-
signment. Access to all parameters which are not set on the basis of standards and technical
rules.
Password = customer-specific (if necessary ask the supplier/manufacturer of the burner soft-
ware; LAMTEC identification code for customers is required).
Production level (level 4)
Access to all parameters (by LAMTEC only).
NOTICE
Each parameter level is protected by means of a separate checksum. We recommend that
you note these checksums on completion of commissioning. They serve as proof that no
changes have been made. Alternatively, back up the data set.
