Air / gas adjustment and output modulation
The air/gas regulator and output modulation system equipping
RS series burners performs a number of integrated functions to
optimise burner function, in both individual installations and in
combination with other units (e.g. double furnace boiler or multi-
ple heat generators in parallel).
The basic system functions control:
1
The dosage of the air and fuel through positioning using
direct servocommands of the relevant valves eliminating the
possible play in the calibration systems with mechanical
cam lever mechanisms, used on traditional modulating
burners.
2
The modulation of the burner output in accordance with the
load required by the system, with maintenance of the pres-
sure or temperature of the boiler at the operating values set.
3
The sequence (cascade adjustment) of more than one
boiler through the suitable connection of the various units
and the activation of the internal software of the individual
systems (option).
Further interfaces and communication functions with computers,
for remote control or integration in central supervision systems
are available on the basis of the configuration of the system.
The first start up and every further internal setting
operation of the adjustment system or the expan-
sion of the base functions require access by
WARNING
means of password and are to be carried out by
service personnel who are especially trained for
the internal programming of the instrument and
the specific application created with this burner.
The first start-up and curve synchronisation manual is supplied
with the burner.
At request, the complete manual for the control and setting of all
parameters is available.
