REGULATION OF EMISSIONS
STEP 1 – LAMBDA ADJUSTMENT
In the technician menu, move the cursor to
Production
by using the
▲▼
buttons and press
OK
on the user interface.
Use the
▲▼
buttons to enter the lambda adjustment page.
Operate the flue gas analyser in line with the manufacturer’s instructions
and measure the flue gas emission.
If the flue gas emissions are outside the required range, adjust the settings
under Lambda adjustment.
CO: max. 75 ppm
NO
X
: max. 50 ppm
If the CO values are too high/low, press:
CO
ADJUST
= Lambda adjustment decrease by -1
NO
X
ADJUST
= Lambda adjustment increase by +1
When reducing CO and/or NOx values it takes a couple of minutes before
the change stabilises on your flue gas analyser. Only make small adjust-
ments at a time in order to achieve the correct values.
STEP 2 – RECOMMISSIONING

®
