THE MANUAL CONFIG MENUS
There are two MANUAL CONFIG menus, one for each flame relay, FR1 and FR2.
In each MANUAL CONFIG menu, the user may select the appropriate Flame-Failure-Response-
Time (FFRT) for the flame relay as well as the on-time-delay setting. The user may also manually
adjust the relay's Flame ON and Flame OFF thresholds, if desired.
Each MANUAL CONFIG menu contains two additional sub-menus, IR SETTINGS and UV SET-
TINGS, (described on the following pages). In the IR and UV SETTINGS menus, the user may man-
ually adjust the sensor Flame Flicker Frequency (BAND), the sensor's USER GAIN, and the sensor's
front-end-gain (FEG) settings, if desired.
Each heading begins with three characters, in this example “R1A”. 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
memory file is selected.
The following descriptions refer to the MANUAL CONFIG FR1 menu.
R1A-SENSOR SLECT
(SELECT)
This option allows the user to select the type of sensor to be used for R1 file selected (A, B, C, D).
Choices include: IR & UV sensors, IR sensor only, UV sensor only. This parameter is used to manu-
ally select which sensor(s) are used in a particular file. Factory default is IR & UV sensors. The
active file that this option will affect is identified in the third position (e.g. R1B is active file “B”).
R1A-FFRT
When the Flame Quality drops to or below the Flame Relay OFF Threshold, the relay will de-ener-
gize after the selected Flame Failure Response Time (FFRT). The choices are 1 to 6 seconds. The
maximum
allowable
FFRT setting is determined by local safety code. The default is 1 second.
Any FFRT selection greater than 4 seconds violates the FM Class 7610 Approval and is therefore
not FM Approved.
R1A-ON THRESHLD
(THRESHOLD)
This refers to the “pull-in” threshold of the internal Flame Relay FR1, in terms of “Flame Quality”.
The ON Threshold can be set from 5 to 100. The ON Threshold must be at least 5 units higher than
the OFF Threshold. Factory default value is 40.
R1A-OFF THRESHLD
(THRESHOLD)
This refers to the “drop-out” threshold of the internal Flame Relay FR1, in terms of “Flame Quality”.
The OFF Threshold can be set from 0 to 95. The OFF Threshold must be at least 5 units lower than
the ON Threshold. Factory default value is 20.
When the Flame Quality is equal to or less than the OFF Threshold (for a time equal to the “Flame
Failure Response Time” setting, see below), the flame relay will de-energize.
R1A- On Time Dely
(DELAY)
When the Flame Quality rises to or above the Flame Relay ON Threshold, the relay will energize
after the selected On Time Delay (OTD). The choices are 1 to 6 seconds. The default is 1 second.
SELECT to Enter FR1 IR Settings
This option allows the user to select IR Band (Frequency default is 179Hz), User Gain (default is 1),
FEG Learned (5), MIN FEG (5), and MAX FEG (255) values for the current active file.
SELECT to Enter FR1 UV Settings
This option allows the user to select UV Band (Frequency default is 179Hz), User Gain (default is 1),
FEG Learned (5), MIN FEG (5), and MAX FEG (255) values for the current active file.
SELECT to Exit to Previous Menu
Return to top of the Config Menu.
