Step Action
Adjust the variables for the internal pressure regulators
Steps 6 to 8 should only be performed if the analyzer module does not
automatically start operation at the pressure values indicated on the
analyzer data sheet. If the internal pressure controller values do not
match these values, the pilot pressures must be changed.
6 Instrument air: Use the external pressure regulator to set the
variable to approx. 60 % (max. 70 %).
Variable too large ⇒ reduce pressure.
Variable too small ⇒ raise pressure.
Input
(The
7 Combustion air: Use the external pressure regulator to set the
variable to approx. 50 % (max. 60 %).
Variable too large ⇒ raise pressure.
Variable too small ⇒ reduce pressure.
8 Combustion gas: Use the external pressure regulator to set the
variable to approx. 35 % (max. 40 %).
Variable too large ⇒ raise pressure.
Variable too small ⇒ reduce pressure.
