t2', t3', t3':
These times are valid only for series 01 or LFL1.335,
LFL1.635, LFL1.638 burner control and command
equipment. They are not valid for types of Series 032,
since they involve simultaneous activation of cams
X and VIII.
Working
The above diagrams illustrate both the connection cir-
cuit and the sequencer mechanism control program.
A Consensus for start-up by means of installa-
tion thermostat or pressure switch "R".
A-B Start-up program
B-C Normal burner operation (on the basis of "LR"
power regulator control commands)
C Stop controlled by "R"
C-D Return of programmer to start-up position "A",
post-ventilation.
During periods of inactivity of the burner, only
the command outputs 11 and 12 are powe-
red, and the air damper is in the CLOSED
position, determined by limit switch "z" of the
air damper servo motor. During the probe test
and false flame test, the flame supervision
test is also powered (terminals 22/23 and
22/24).

Safety standards

• In association with the use of QRA..., earthing of
terminal 22 is compulsory.
• The power cables must conform to existing natio-
nal and local standards.
• LFL1... is a safety device, and it is therefore for-
bidden to open it, tamper with it or modify it!
• The LFL1... device must be completely insulated
from the mains before carrying out any operations
on it!
• Check all the safety functions before activating
the unit or after replacing a fuse!
• Provide protection against electric shock on the
unit and all electric connections. This is ensured
by following the assembly instructions correctly!
• During operation and maintenance, prevent infil-
tration of condensate into the command and con-
trol equipment.
• Electromagnetic discharges must be checked on
the application plan.
Control program in the event of stopping, indicating position
of stop
As a rule, in the event of any kind of stop, the fuel flow is cut off
immediately. At the same time, the programmer remains immobi-
le, as does the switch position indicator. The symbol visible on the
indicator reading disk indicates the type of fault.
No start-up, because of failure in closing of a contact
or lock-out stop during or at the end of the command
sequence because of external lights (for example: flames
not extinguished, loss at the level of the fuel valve, defects
in the flame control circuit, etc.)
Start-up sequence stops, because the OPEN signal was
not sent to terminal 8 by limit switch contact "a". Terminals
6, 7 and 15 remain powered until the defect is eliminated.
P Lock-out stop, because of lack of air pressure signal.
Any lack of pressure from this moment onwards will
cause a lock-out stop!
Lock-out stop because of flame detection circuit malfun-
ction.
Start-up sequence stops, because the position signal
for low flame was not sent to terminal 8 by auxiliary switch
"m". Terminals 6, 7 and 15 remain powered until the fault
is eliminated.
1 Lock-out stop, due to lack of flame signal at the end of
the first safety time.
2 Lock-out stop, because no flame signal was received at
the end of the second safety time (main flame signal with
pilot burners at intermittent operation).
Lock-out stop, due to lack of flame signal during burner
operation.
If a lock-out stop occurs at any moment between the start and
pre-ignition without a symbol, the cause is generally to be attribu-
ted to a premature or abnormal flame signal caused, for example,
by self-ignition of
a UV tube.
