SETTING LOW FIRE
NOTE:
As soon as a servo position is altered, the servo will move to that position.
Only change servo settings by a maximum of 0.5° at a time before verifying
combustion.
1. Go
to
Params&Display >RatioControl >GasSettings>CurveParams.
2. Wait for the spinning line on the left to disappear. Press Enter. The number
1 should appear to the right of the cursor, this is the Point Number.
3. Press
Enter once. Select ChangePoint by pressing the arrow keys to
highlight and then press Enter to select. This will cause the servo motors to
move to this low fi re point.
4. Check combustion and adjust the servo motors as required. To adjust
a servo motor, arrow to it and press Enter. Then adjust the setting as
required and press Enter. You can now adjust another servo motor if
needed.
5. When combustion is properly set for that point, press Escape. If it asks you
to store the point, press Enter. Note the AZL will only ask to save if either
servo value has been altered.
6. Low
fi re is now set and stored.
SETTING THE COMPLETE RANGE
1. Remember it is only necessary to approximate the setting through the
modulation range until high fi re conditions are established.
2. Press
Enter once more to have access to the point number fi eld. Increase
the point number by one and press Enter. Select ChangePoint and press
Enter. The servos will now move to that point.
3. Verify combustion is satisfactory.
4. Measure input or monitor last elbow pressure. Verify that these points are
in general correspondence with the test fi re sheet. Repeat step 2 until the
point position has a load value of 100%.
5. You are now at high fi re. Verify combustion is per test fi re sheet.
6. Once at high fi re, adjust the incoming gas pressure at the main gas
regulator to match the test fi re report. Adjust the gas servo motor to
change the last elbow pressure to match the test fi re report.
7. Adjust the air servo motor to adjust the emissions as needed.
8. Repeat step 2 but start at the high fi re point number. Continually decrease
the point number after combustion has been verifi ed at each point.
9. Once all the points have been verifi ed, press Escape until you are back to
the main menu.
10. You can observe the status of the burner by going to OperationalStat
