6 Operational-Modes

Operational-Modes

SF910i uses three modes of operation. In each mode, the SF910i operates to provide

the optimal user interface.

Operational-Modes are:

–

First-time power-up mode

–

Normal-Mode (Live data view)

–

Configuration-Mode (Programming)

Except for the first-time power-up, the modes of operation are not mutually exclusive.

For instance, when configuring, the SF910i maintaining its operability belonging to the

normal mode (i.e., it continues to detect the flame, if it was in normal mode before entering

the configuring mode). In other words, the SF910i is "online configurable".

6.1

First-time Power-up Mode

When the SF910i is factory new or when the user make a complete reset of the

configuration to factory defaults or when the configuration stored in non-volatile memory

is not recognized as a valid one, it operates in a mode called "First-time power-up".

The most important feature of this mode is to prevent flame-relay from energizing

until authorized user performs a configuration/tuning.

In this mode:

–

Flame-relay is not energized (even if the flame algorithm votes for flame-ON).

–

Flame LED is blinking red (slow).

A distinction must be done at protocol level:

–

Factory default and manual reset of the configuration, both bring the unit in MODBUS

mode speed of 38.400 b/s, and station address equal to one.

–

Reset to default configuration driven by the detection of a configuration error

maintains the protocol that was active before the configuration error was.
