conditions (e.g.: Flame On = 10, Flame Off = 40, difference = 30). The lower the value, the stronger
the flame signal. During Flame On, a lower number is desirable; during Flame Off, a higher number
is desirable. This setpoint also calculates the automatic gain adjustment. See Setup Procedure.
Note: This setpoint is not programmable.
Note: See Caution below.
Learn a “New” Flame On Signature (L ON NEW)
- Learns a new
Flame On
signature profile
(See Programming Primer, Publication CU-33). During the “learn” mode, the signature profile is
stored in EDIT memory, erasing any existing
Flame On
signature profile already in EDIT memory.
Note: To display L ON NEW, press the change key (
▲
)
when L ON ADD is displayed in order to
toggle back and forth between L ON NEW and L ON ADD
Note: Signature profile must be saved to a file (A, B, or C) before use.
CAUTION: If the setpoints FFRT, BFRT, Fuel Type, or Burner Type have been changed
after the flame signature was learned, or the scanner was re-aimed, the user must perform
“Learn Flame ON and Off New” procedures again to insure safe and proper operation.
Learn and Add to an Existing Flame On Signature (L ON ADD)
- Learns another
Flame On
signature profile (See Programming Primer, Publication CU-33).
Note: To display L ON ADD, press the change key (
▲
)
when L ON NEW is displayed in order to
toggle back and forth between L ON NEW and L ON ADD.
During the “learn” mode, the signature profile is stored in EDIT memory, adding to and modifying
any existing
Flame On
signature profile already in EDIT memory. Additional
Flame On
information
may improve flame detection.
Note: Signature profile must be saved to a file (A, B, or C) before use.
Learn a “New” Flame Off Signature (L OFF NEW)
- Learns a new
Flame Off
signature profile
(See Programming Primer, Publication CU-33). During the learn mode, the signature profile is stored
in EDIT memory, erasing any existing Flame Off signature profile already in EDIT memory.
Note: To display L OFF NEW, press the change key (
▲
)
and L OFF ADD is displayed in order to
toggle back and forth between L OFF NEW and L OFF ADD.
Note: Signature must be saved to a file (A, B, or C) before use.
Learn and Add to an Existing Flame Off Signature (L OFF ADD)
- Learns another Flame Off
signature profile (See Programming Primer, Publication CU-33).
Note: To display L OFF ADD, press the change key (
▲
)
when L OFF NEW is displayed in order to
toggle back and forth between L OFF NEW and L OFF ADD.
During the learn mode, the signature is stored in EDIT memory, adding to and modifying any exist-
ing Flame Off signature profile already in EDIT memory. Additional Flame Off information may
improve flame out detection.
Note: Signature profile must be saved to a file (A, B, or C) before use.
Save a Signature to a File (SAVE)
- Saves a reference signature profile to a file (A, B, or C). This
also saves the values of all of the other setpoints as well (e.g. FFRT. Type of Fuel, etc.).
Run the Reference Signature from a File (RUN)
- Once a signature profile has been saved to a file,
this command selects the reference signature profile (and the values of all the other setpoints saved
as well, e.g. FFRT, Type of Fuel, etc.) stored in the indicated file for comparison against the moni-
tored flame. This command sends the flame signature profile to RUN memory.
Abort and Exit the Setpoints Menu (ABORT)
- Exits the Setpoints Menu.
