CONFIGURATION PARAMETERS
The configuration defines the ESA ESTRO functioning
mode, adapting it to the needs of the plant. Certain confi-
guration parameters are defined and blocked by the fac-
tory in conformity to the related application norms. Others
instead, can be altered by the user with the aid of suitable
equipment. The modification of the parameters is accep-
ted by the ESA ESTRO when it is in the manual stop con-
dition and can be done with a portable programmer or
dedicated software via a serial interface card. The porta-
ble programmer communicates via infrared interface and
allows the serial communication parameters to be altered.

VALUE DESCRIPTION
N° NAME
/
Address
Segment
0 ÷ 9 and
A ÷ Z
capital letters
With “Address Segment” the device is indentified for serial communica-
tion. The ECS protocol identifies the zone or the group to which it
belongs. With Modbus-RTU protocol the address tens are defined (0÷F
for 0÷16 tens).
/ Address Node
0 ÷ 9 and
A ÷ Z
capital letters
With “Address Node” the device is indentified for serial communication.
The ECS protocol identifies the unit inside the zone or group. With
Modbus-RTU protocol the address units are defined (0÷9 units).
2 Cycle start
Automatic ignition
Autostart
When powered the instrument automatically starts the ignition cycle, at
less than one block before shut down. This configuration is useful when
controlling the burner through the power of the instrument.
Standby
At power on the instrument does not start the ignition cycle but waits for
the local or remote ignition command. This configuration is useful when
controlling the the burner through serial communication to avoid simulta-
neous ignitions or for applications that require operator action every time.
3 Prepurge time
0 ÷ 99 sec
2 ÷20 min
Chamber purge or waiting time before burner ignition. In applications
with air shutter or flow control, the timing starts at maximum opening or
with target purge flow (FSL).
5
Regulation
delay time
2°safety time
0 ÷ 25 sec
Waiting time following the stability check phase of the 1st gas stage, after
which air valve regulation is allowed (ESTRO-A and expansions). For the
ESA ESTRO-B version this time corresponds to the second safety time
(2nd gas stage ignition), for which the parameter is blocked and cannot
be changed. Furthermore, when this time has expired, the 1st gas stage
shuts down when it is interrupted.
7
Behaviour at
flame failure
Lockout
The instrument determines shut down in burner lockout, caused by flame
signal extinction for longer than the time set in the “Reaction time” para-
meter (reset is required).
Recycle
The instrument performs a sequence of complete ignition (including pre-
purge) after the flame signal has disappeared. When burner ignition has
taken place correctly, at the next flame extinction, the instrument per-
forms another ignition sequence.
The software installed on the pc instead, communicates
via the ECS serial interface and allows all the non bloc-
ked parameters to be altered. With the aid of the softwa-
re, the user can block other parameters, with the restric-
tion that the blocks can only be removed by the manufac-
turer or by the person who entered them. Configuration
via the ECS serial interface is allowed for one instrument
at a time, and it is compulsory to disconnect the network
on field and connect it directly to the ECS interface card
connected to the PC.
