Set min. output 1st stage:
•
Set burner to low load 1st stage and correct
exhaust gas values at "N".
for GG20-M-L-LN:
To do so, set the output controller to min. output
(contact from "T6" to "T7" in socket unit X32).
for GG20-Z-L-LN:
Set 1st/2nd stage switch to 1st stage.
•
Adjust nozzle pressure by adjusting cam
ST1/min. according to the table.
•
Correct the exhaust gas values at "N".
•
For the positioning drive to approach the newly set
cam position, the output controller must be set to
max. output requirement for a few seconds (contact
from "T6" to "T8").
The positioning drive moves up.
•
Reset the output controller to min. output request again (contact from "T6" to "T7").
The positioning drive moves to the newly set min. position.
On the 2-stage sliding version, set the switch 1st/2nd stage briefly to 2nd stage and then reset to 1st
stage.
•
Correct the exhaust gas values at "N".
•
If necessary, repeat adjustment procedure of cam position ST1/min. output as described above until
desired nozzle pressure is achieved.
•
As the adjustments "V“ and "N“ mutually influence each other, the burner must be run up and down
several times between max. and min. heat requirement of the 1st/2nd stage output controller.
•
For max. output, correct 2nd stage exhaust gas emission by adjusting "V“ and for min. output correct
1st stage by adjusting "N“.
•
Start the burner; if the burner does not start, alter "N“ in direction "+“ and start burner again. Check
exhaust gas emission and, if necessary, alter 1st stage min./start output.
