BARGRAPH
ESA
ESTRO has a bargraph with five leds indicating the
flame value detected in a range of 0µA to 90µA. If the
detection current is greater than 90µA the upper led is
kept on. The flame detection signals generated by elec-
trodes (ionization) are sensibly lower that compared with
the signals generated by the UV probe, however, in both
cases the stability of the indication on the bargraph is
related to the stability of the signal detected by the bur-
ner flame.
DISPLAY STATUS DESCRIPTION
FIXED
Programming phase from serial input via the special configuration software.
During this phase it is not possible to carry out any other operation.
FIXED
Programming phase from infrared input via the special programmer. Fase di
programmazione da ingresso infrarosso tramite l’apposito programmatore.
During this phase it is not possible to carry out any other operation.
Configuration
LOCAL BUTTON
ESA ESTRO allows the configuration of the local button
according to the application needs (see Configuration
Parameter paragraph). The button can carry out the lock
and manual stop functions as well as only lock or only
manual stop or else it can be disabled with the possibility
of being activated by serial communication.
The button action differs depending on the function:
¾
¾Unlock:
the local button must be kept pressed for 1 to
3 seconds and when released ESA ESTRO unlocks the
condition. If pressed for less or longer than specified, the
command is not accepted.
¾
¾Halt in manual stop: as soon as the local button is
pressed, ESA ESTRO activates the halt.
