MICROPROCESSOR OPERATED BURNER CONTROL DEVICE
ESA ESTRO is a microprocessor operated device, designed to
control gas and oil fired burners, discontinuously operated.
This device warrants the safe operation of combustion unit at
one or two stages (pilot and main burners), it controls the air
flow rate and allows the detection of flame presence through
ionization (electrodes) or UV radiation (UV-scan).
ESA ESTRO is equipped for serial communication, allowing a
remote burner control and operation. The thermal resistant
case of ESA ESTRO allows its installation on burner proximity,
provided the environment temperature will remain below 60° C.
One or two stages (pilot and main) discontinuous burners;
-
Flame detection by means of rod, unirod and UV scan (also
-
combined);
Packaged burners managing a complete ignition cycle
-
(blower, air damper, air pressure switch);
Burners with air valve control for furnace purging, burner
-
ignition and thermoregulation (heating/cooling) via external
regulation device;
-
Combustion plant with burners controller via digital signal or
ECS serial communication;
Customized burners operation through programmable
-
expansion cards.

- Page 3 E7014 DESCRIPTION ESA ESTRO is a device based on microprocessor technology, provided with input and output connections, suitable to control discontinuous burners operation (at least one burner shutoff each 24 hours). The instrument is available in four different releases. • ESA ESTRO- A: single stage burner (one gas valve) with air valve operation control The configuration software allows the proper definition of the air valve operation.
- Page 4 E7014 • ESA ESTRO-Q: single stage burner (one gas valve) dedicated to combustion unit controlled via serial communication modes. IGNITION REMOTE TRANSFORMER CONTROL ESTRO GAS VALVE FLAME SIGNAL Moreover the release ESTRO-A, ESTRO-B and ESTRO-C allow to set an output signal for burner lockout and a digital input signal.
- Page 5 E7014 On its front panel ESA ESTRO mounts a programmable push button, an alphanumeric display of status indication, a bargraph flame signal indicator and the infrared communication port for “on field” instrument’s configuration. Dedicated configuration software allows the definition of several operation parameters, according process requirements, like the control of the air valve, the lockout output signal, the scheduled time for each phase (according the ranges defined by the reference norms).
