COMMAND AND CONTROL EQUIPMENT
FOR GAS BURNERS LFL 1...
Command and control equipment for mid and large output blown-
air burners
(intermittent service *) for 1 or 2 stage burners or for modulating
burners with air pressure monitoring for air shutter control. The
command and control equipment feature the EC mark according
to the Gas and Electromagnetic Compatibility Directive.
* For safety reasons, it is important to perform a controlled stop
each 24 hours!
As regards the standards
The following LFL1.... features fully comply with the Standards
and ensure an extremely high safety level:
• 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 immediately after the regulation stop, a
shutdown in lock condition 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 validity of operation of the flame control circuit is checked
every 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 for the burner control
• The equipment allows operation with or without post-ventilation.
• Air shutter controlled command to ensure pre-ventilation at
nominal air flow. Controlled positions: 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 servomotors fail to
position the air damper in the preset points, the burner does
not start.
• Ionization current minimum value = 6mA
• UV cell current minimum value = 70mA
• Phase and neutral must not be inverted.
• Any assembly position and place (IP40 protection)
