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).

ESA ESTRO is provided with a solid case in thermosetting composition, ready to seat the ignition

transformer and the output wires for external connections.

Dedicated Expansion cards can be connected to each release of ESA ESTRO, in order to implement

additional features or specific serial communication modes. The installation of an expansion card into the

ESA ESTRO device obliges to install the ignition transformer into an external thermosetting case named

ESA TRAFO.

Hereinafter the expansion cards available are described according their main features:

• EXP-2: dedicated to “package burners” controls the air valve or blower start, verifies the air pressure

switch signal and operates the initial purging and burner ignition procedures.

Expansion card EXP-2 could be also adopted to simply operate the air valve (for device releases

different from ESTRO–A).

• EXP-3: developed to implement serial communication with the most common fieldbus standards.

For detailed information please refer to the technical bulletin E7015.

E7014

• EXP-4: provided with four digital inputs, four digital outputs, one analog input, one analog output and a

serial interface in order to allow remote card control.

ALPHANUMERIC VISUALIZATION AND PUSHBUTTON

DISPLAY

ESA ESTRO displays through several symbols the status of the burner control device. Fixed characters

indicate the normal operating conditions or some instruments’ failures that cannot be restored, while

lockout conditions or restorable failures are indicated with blinking symbols.

Normal operation stages

DISPLAY INDICATION DESCRIPTION

FIXED

Self-diagnosis phase; the equipment controls the efficiency of its

components. It is shown every time the equipment is powered or when

the burner is re-started (it lasts near 2 sec).

BLINKING

Manual lockout. The equipment is waiting for the operator’s reset

command via the local, remote or serial button. It is shown every time

the equipment is powered in case the parameter “Power on” is

configured as “Stand-by".

FIXED

Burner shutoff caused by the temp controller. The instrument leads the

burner in “off” mode, close the air valve and disables others exits.

FIXED

Air pressure switch signal waiting phase after air valve activation (or

blower start), or burner shutoff during operation in case of incorrect air

pressure signal. It is shown with expansion cards in case the parameter

“Air switch” is configured as “Waiting”.

FIXED

Initial purging: air valve is opening and the maximum opening position

is not yet reached (position switch). It is shown with expansion cards in

case the parameter “Air damper” is configured as “Local o Remote".

FIXED

Purge or waiting time before burner ignition. For applications with

controlled cooling slope, only the air valve is open in this phase. At this

stage the device verifies the presence of illegal flames and eventually

generates a shutoff reaction.

FIXED

Initial purging: air valve is closing and the minimum opening position is

not yet reached (position switch) to warrants ignition at minimum firing

rate. It is shown with expansion cards in case the parameter “Air

damper” is configured as “Local o Remote".

FIXED

Burner ignition at 1

stage gas, it lasts as the first safety time. The

device activates the ignition transformer and the 1st stage gas valve,

then deactivates the transformer and verifies the flame presence.

FIXED

Check of flame stability at 1

stage gas, followed by the flame’s

amplifier control. This phase is shown also in case of shutoff of the 2

stage burner.

FIXED

Normal operation stage for ESTRO-A, ESTRO-C and ESTRO-Q. For

ESA ESTRO-B release it signals the 2

stage gas burner and it lasts

as the second safety time. In this phase both 1

and 2

gas valve are

activated. This is the normal operation stage also for ESA ESTRO-B in

case the parameter “1st stage gas” is configured as “Intermittent”.

FIXED

Normal operation stage for ESA ESTRO-B with only 2

stage gas

burner activated. The device closes the 1st stage gas valve. This phase

is present only in case the parameter “1st stage gas” is configured as

“Interrupted”.

E7014

FIXED

Normal operation stage with air valve activated. In case the parameter

“Air switch” is configured as “Lockout or Waiting" the device waits the

signal of the air pressure before to show this stage, while when

configured as “Disable” the switch to this stage coincides with the air

valve opening. This phase is present only in case the parameter “Air

flow control type” is configured as “Discontinue or Pulse”.

FIXED

The device verifies the flame’s complete extinguishment in maximum

20 sec. after burner shutoff; otherwise a lockout signal for illegal flame

presence is activated.

FIXED POINT

Furnace purging with air (or waiting phase) after burner shutoff.

During this phase the device doesn’t accept any command and shows

the symbol referred to the phase or block that activated the shutoff

procedure.

FIXED

Burner shutoff phase requested by temp. controller. The device hold the

burner in “OFF” mode waiting for a new start signal, keep closed the air

valve and deactivate the output signals.

BLINKING POINT

High Temperature Operation mode active. During this phase the device

shows the fixed code related to the active phase.

Lockouts or failures

DISPLAY INDICATION DESCRIPTION

BLINKING

Manual burner shutoff, executed through local or remote push button

during the normal operation stage. The device holds the burner in “OFF”

mode waiting for a new start signal.

BLINKING

Lockout due to a signal of illegal flame presence, before the burner

ignition or after burner shutoff. The causes could be related to the

detection device (failure) or to a fuel gas leaks through the interception

solenoid valves.

BLINKING

Lockout due to a failed burner ignition attempt at 1

stage gas. The

causes could be related to the ignition devices (electrode and/or

transformer), to wrong air/fuel ratio gases, or to the flame detection

device (probe or wiring failure). On the first mentioned case the burner

is not ignited, vice versa on the second the flame is present but ESA

ESTRO is unable to detect it.

BLINKING

Lockout due to a missing flame presence signal during the normal

operation stage. The causes could be related to a wrong air/fuel ratio

(too fast flows variation or ratios out of the flame stability range), or to

the flame detection device (probe position or cleanliness).

BLINKING

Lockout due to the extended absence of serial signals from the remote

controller, for a period of time longer than the parameter set as

“Communication timeout”.

The causes could be related to wrong connections or to the serial

communication management.

FIXED

Malfunction due to the presence of the air pressure switch signal before

the blower activation. The causes could be related to a wrong pressure

switch wiring or in its failure.

E7014

BLINKING

Lockouts due to a malfunction of the inner circuit for air pressure switch.

In case after a reset procedure attempt the indication is still present, the

device has to be sent back to the manufacturer for inspection

BLINKING

Lockout due to the missing signal from the air pressure switch during

normal operation stage. The causes could be related to a pressure

switch failure or to some problems related to the air flow (i.e. filter

obstruction).

BLINKING

Lockout due to the presence of the signal of air valve complete opening

(“maximum” position switch) before the device allowed the valve

opening. The causes could be related to a wrong electrical wiring or to a

wrong air valve switches regulation.

BLINKING

Lockout due to the presence of the signal of air valve complete closure

(“minimum” position switch) before the device allowed the valve closure.

The causes could be related to a wrong electrical wiring or to a wrong

air valve switches regulation.

BLINKING

Lockout due to the missing closure of the air valve after the initial

purging phase. The device waits for a maximum of 150 sec. from the

closing command the signal generated by the “minimum” valve position

switch. The causes could be related to a wrong electrical wiring or to a

wrong air valve switches regulation.

BLINKING

Lockout due to the missing electrical absorption from the ignition

devices connected to ESA ESTRO ( ignition transformer or solenoid

valves). The causes could be related to an electrical connection

interruption, to the failure of one of the ignition devices or to a protection

fuse failure.

BLINKING

Lockout due to a malfunction of the flame detection probe. The causes

could be related: to a probe failure, to a short circuit between the probe

or his connection to ground (burner body), to the reverse connection of

UV tube ESA UV-2, to a wrong or connection of the ground at the

device, or to strong current on the furnace ground (welding in progress).

BLINKING

Lockout due to a malfunction of the inner flame amplifier. In case after a

reset procedure attempt the indication is still present, the device has to

be sent back to the manufacturer for inspection.
