COMMAND AND CONTROL EQUIPMENT LFL
1.333 series 02
Command and control equipment for forced air burners with
medium to high capacity (intermittent service
*) for 1 or 2 stages or modulating burners with air pressure
supervision for controlling the air gate. The command and
control equipment feature the EC mark according to the
Gas and Electromagnetic Compatibility Directive.
* For safety reasons make at least one controlled stop every 24
hours!
As regards the standards
The following LFL1.... features fully comply with the Stan-
dards and ensure an extremely high safety level:
- The flame detector test and the false flame test start immediately
after the allowed post-combustion time. If the valves remain
open, or do not close immediately after the adjustment stop, a
shutdown is triggered at the end of the allowed post-combustion
time. The tests finish only at the end of the pre-ventilation time
of the next start-up.
- The operation validity of the flame control circuit is verified upon
each burner start-up.
- The fuel valve control contacts are checked for wear during the
post-ventilation time.
- One fuse integrated in the equipment protects the control con-
tacts against possible overloads.
As for the burner control
- The equipment allows operation with or without post-ventilation.
- A i r g a t e c o n t r o l l e d a c t i v a t i o n t o e n s u -
r e p r e - v e n t i l a t i o n w i t h n o m i n a l a i r f l o w r a t e .
Checked positions: CLOSED or MIN (ignition flame position
upon start-up), OPEN at the beginning, and MIN at the end of
the pre-ventilation time. If the servomotors fails to position the
air gate in the preset points, the burner does not start.
- Ionization current minimum value = 6µA
- UV cell current minimum value = 70µA
- Phase and neutral must never be inverted.
- Any place may be used for installation and assembly (IP40
protection class).
