11 Configuration Parameters in Flame Explorer
The configuration needs to know, if the sensor is single or dual (this information is needed
to the Flame Calculation Algorithm). No details on the sensor spectral sensitivity are
needed at this point. The sensor type is automatically recognized by the firmware residing
on the SF910i. The sensor type can be read from the tool accessing to the unit's advanced
status page (see Show Sensor Type) in this section.
Alternative Flame Logic (for DUAL Sensor Modules only)
This field is editable only, if the SF910i is working with a dual sensor. In this case, it is
possible to configure the unit to vote flame conditions by calculating an OR or an AND
of the flame condition detected independently by the two sources.
– Selecting OR, the unit will vote FLAME ON if at least one of the two sources detects
flame presence.
– Selecting AND, the unit will vote FLAME ON if both sources detect flame presence.
Operating Mode
Operating mode can be:
– Wall Industrial (default)
– Lighter
– Turbine
– Corner
– Pyrometer
Active Function Set
This gives information about which function sets are active. "FSA" is displayed for single
sensor. "FSA and FSC" are displayed for dual sensor. Other function sets are not used
and could not be changed for SF910i.
Safe Relay Usage
Safe relay can be used in four different ways. Refer to
Analog Output
Use the Analog Output function to specify the type of information that will be transmitted
to the 4 to 20 analog output. This information can be related to:
Intensity
This option will output the intensity value in a range of 4 to 20 mA = 0 - 100%.
