THE IR AND UV SETTINGS MENUS
Each MANUAL CONFIG menu contains two sub-menus, IR SETTINGS and UV SETTINGS. In
the IR and UV SETTINGS menus, the user may manually adjust the individual sensor values.
Each heading begins with five characters, for example “R1AIR”. The first two characters (R1 or
R2) indicate which relay (FR1 or FR2) is selected. The third character (A,B,C, or D) indicates which
file is selected. The last two characters (IR or UV) indicate which sensor's settings are being edited.
The following descriptions refer to the FR1 IR SETTINGS menu for file A.
R1AIR - BAND (Freq)
There are twenty-one choices of flame-flicker-frequencies (BANDS): 23, 31, 39, 46, 54, 62, 70, 78,
85, 93, 101, 109, 117, 125, 132, 140, 148, 156, 164, 171 and 179Hz.
R1AIR-USER GAIN
Adjust the sensor gain (1-31) so that the flame ON signal strength is well above the flame relay ON
threshold, and the flame OFF signal strength is well below the flame relay OFF threshold.
Each upward step in the User Gain setting will increase the Signal Strength number for the selected
sensor by approximately 50%. Each downward step in the User Gain setting will decrease the Signal
Strength number for the selected sensor by approximately 33%.
Example 1: Assume that you observe an IR Signal Strength of "080" when the IR User Gain set-
ting is 12. If you then increase the IR User Gain setting from 12 to 13 you should expect to see the
IR Signal Strength increase to approximately "120".
Example 2: Assume that you observe an IR Signal Strength of "240" when the IR User Gain set-
ting is 20. If you then decrease the IR User Gain setting from 20 to 19 you should expect to see the
IR Signal Strength decrease to approximately "160".
R1AIR FEG LRNED
(LEARNED)
The Front End Gain value stored when LEARN ON was performed. Possible values (5-255).
R1AIR MIN FEG
If the real-time Front End Gain value falls below this setting, the IR flame signal will be driven to
zero. Possible values (5-255), default (5).
R1AIR MAX FEG
If the real-time Front End Gain rises above this setting, the IR flame signal will be driven to zero.
Possible values (5-255), default (255).
Note: On the FEG settings screens, the current “real-time”
FEG value is also shown on the left side of the display.

MANUAL SET-UP IN MANUAL CONFIG FR1 & FR2 MENUS
In Manual Configuration, the user may set values for FR1 and FR2. Separate displays show the
BAND (Freq), User Gain (1-31), FEG Learned, FEG Min and Max for the IR and UV sensor.
In the Manual Config Menu with the target flame ON
(at low fire), record the sensor signal
strength and stability at each of the 21 modulation BANDS: 23, 31, 39, 46, 54, 62, 70, 78, 85, 93,
101, 109, 117, 125, 132, 140, 148, 156, 164, 171 and 179Hz. The signal strength range is 0-999.
