Air Flow Rate Adjusting Procedure
Adjusting procedure
• Set the selector switch to its "Manual"
or "Hand" position.
Air flow rate adjustment
The air control curve of the compound
controller is factory-set so that the air
damper is closed in minimum position
and open in maximum position.
The combustion air flow rate required
for proper fuel combustion is controlled
by an electronic fuel-air compound con-
trol system over the full load range. A
check is made by analyzing the exhaust
gases.
For the gradual adjustment of the
load points (fuel flow rate, air flow
rate), a procedure should be used as
described in the operating instruc-
tions for the electronic compound
control system.
A fuel test should be made at each point
if possible.
