BGN 540 LX / LX-V ELECTRODES ADJUSTMENT DIAGRAM
INSTRUCTIONS LFL 1.... CONTROL BOX
Control box for burners of average and high power, with forced draught, intermittent service (*), 1 or 2 stages, or
modulating types, with supervision of the air pressure for controlling the air damper.
This control box bears the EC mark, in accordance with the Gas and Electromagnetic Compatibility Directive.
* For reasons of safety, it is necessary to make at least one controlled stop every 24 hours!
As regards the standards
The following LFL1... features exceed the standards, offering a high level of additional safety:
- The flame detector test and false flame test start immediately after the tolerated post-combustion time. If the valves remain
open, or do not close completely after adjustment stops, a lock-out stop is triggered at the end of the tolerated post-combustion
period. The tests will end only at the end of the pre-ventilation time of the next start-up.
- The validity of working of the flame control circuit is checked each time the burner starts up.
- The fuel valve control contacts are checked for wear during the post-ventilation time.
- A built-in fuse in the appliance protects the control contacts from any overloads that may occur.
As regards the burner control
- The equipment allows operation with or without post-ventilation.
- Controlled activation of the air damper to ensure pre-ventilation with nominal airflows. Positions checked: CLOSED or MIN
(position of ignition flame on start-up); OPEN at the beginning and MIN at the end of the pre-ventilation time. If the servomotor
does not position the air damper at the points described, the burner does not start-up.
- Ionization current minimum value = 6mA
- UV cell current minimum value = 70mA
- Phase and neutral must not be inverted.
- Any place may be used for installation and assembly (IP40 protection).
