10 Duties of the authorized inspector

Prior to approval, the manufacturer must state the assigned DIN registration number
and product ID number confirming that the LMV51... burner management system
complies with the type-tested system.
Also, only the components specified for use with the LMV51... system (AZL51...,
actuating devices, flame detectors, transformer and bus cable) may be used.
Flame detectors QRB...
Flame detector QRI...
Actuators SQM4...
Operating and display unit AZL51...
Transformer AGG5...
The mechanical links between the actuators and the fuel and air actuating devices and
any other actuating devices used must be rigid.
In addition, following must be checked:
The parameterized values and the breakpoints of the curves that describe the fuel / air
ratio control system must be documented by the plant manager after installation and
commissioning.
As long as it is not possible to print with the PC software tool, the parameters and
breakpoints need to be documented in some other form (handwritten on forms) and
attached to the plant documentation.
The values and curves parameterized on the plant must be presented to the authorized
inspector.
The following parametes are of particular importance:
Fuel / air ratio control system
The setting values (curve parameters) for the actuating devices, the types of fuel and
the combustion air across the burner's load range must be stored in adequate numbers.
While considering the combustion chamber pressure, fuel pressure as well as
temperature and pressure of the combustion air, assignment of the selected setting
values of fuel and combustion air must be made such that correct operation with
sufficient amounts of excess air is ensured across the entire burner load range.
Proof of this must be delivered by the burner / boiler manufacturer by measuring the
combustion characteristics.
Burner control section
Fuel train parameterization (G, Gp1, Gp2, LO, HO, LOgp, HOgp, refer to chapter «Fuel
trains») must be checked prior to commissioning to ensure it agrees with the fuel trains
implemented on the burner and to make certain the valves are correctly assigned to the
valve outputs on the LMV51... .
