More Information

Overview Manuals Flame Detection Display and Diagnostics System Interfaces Application
  • The Limelight DFI-100 platform discriminates between ignitor Flame and No Flame conditions
  • The self-contained electronics mount in an ignitor control cabinet or nearby junction box
  • The DFI-100 platform supports flame-rod and optical-detector sensing arrangements

DFI-100-340F is an ALSTOM Limelight diagnostic flame indicator for ignitor flame proving.

Manufacturer DFI-100 documentation describes a self-contained unit that analyzes a flame-rod or optical signal, indicates flame quality and faults, and provides relay and process interfaces to the surrounding burner system.

Because the accessible manufacturer manual describes the DFI-100 family rather than the complete -340F suffix, verify the physical nameplate, supply, terminal diagram, sensing method, configuration, and replacement revision before service.

Availability, condition, price, and shipping time for DFI-100-340F are confirmed during quotation.

  • The DFI-100 is designed to discriminate between ignitor Flame and No Flame conditions
  • A flame-rod installation evaluates the changing flame-current signal produced by flame conductivity
  • An optical installation converts flame light through a compatible detector head for signal analysis
  • Front indicators report power, flame state, reliability, and detected fault conditions
  • The LED bar graph can represent intensity, frequency, AC value, or flame quality
  • The display and pushbuttons support local review and configuration of DFI operating information
  • The DFI-100 family provides flame and auxiliary relay interfaces for the burner system
  • Four dry-contact digital inputs are documented for ignitor-run and combustion permissive signals
  • A loop-powered 4-to-20-milliampere analog output is documented for external indication
  • Ignitor flame proving in utility and industrial burner-management systems
  • Flame-quality indication and troubleshooting for flame-rod sensing installations
  • Optical ignitor-flame monitoring with a compatible detector head and validated configuration
Description
DFI-100-340F is an ALSTOM Limelight diagnostic flame indicator used to determine ignitor Flame and No Flame conditions.

The DFI-100 architecture analyzes flame-rod or optical-detector signals, presents flame-quality and fault information, and exchanges status through relay, digital-input, and analog-output interfaces.

Before installation or replacement, confirm the complete -340F nameplate, input supply, sensing method, terminal diagram, relay logic, configured thresholds, burner permissives, and approved revision compatibility.

Technical notes
DFI-100-340F is an exact catalog identity, but the accessible ALSTOM manual covers the DFI-100 family and a later revision. Verify the -340F nameplate, supply rating, sensing method, and terminal diagram before installation or replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the flame-proving relay behavior be verified on ALSTOM DFI-100-340F?
ALSTOM DFI-100 documentation defines the main relay as energized when flame is proven and de-energized when flame is lost. Confirm the DFI-100-340F terminal diagram before connecting this relay to the ignitor trip logic.
Can ALSTOM DFI-100-340F parameters be edited locally and remotely at the same time?
The documented DFI-100 interface uses an interlock to prevent simultaneous editing. If local program mode is requested while remote editing is active, a warning is displayed and the unit returns to normal mode.
Which RS-485 communication settings are documented for the ALSTOM DFI-100-340F family?
Later DFI-100 documentation specifies Modbus RTU communication at 19200 baud with 8 data bits and no parity. The Modbus slave address is configurable; confirm that these settings apply to the installed DFI-100-340F revision.
How does the documented First Out function relate to ALSTOM DFI-100-340F?
The DFI-100 First Out function can monitor the ignitor-run, combustion-air, trip-valve, and fuel-flow or pressure inputs. It records the first enabled input that opens before flame is lost and ignores an input that closes again before flame loss.
What happens when a documented internal self-test fails on ALSTOM DFI-100-340F?
ALSTOM DFI-100 documentation states that a failed self-test removes power from both output relays and initiates a reboot. If the fault remains, the unit continues cycling between reboot and self-test.
Which grounding details should be checked when wiring ALSTOM DFI-100-340F?
The DFI ground terminal must connect directly to cabinet ground. For a flame-rod installation, the wire-train ground must also connect directly to cabinet ground and must not be connected to the DFI ground terminal.
What should be checked before replacing ALSTOM DFI-100-340F?
Confirm the complete label, supply, sensing method, terminal diagram, relay logic, configured thresholds, burner permissives, and approved revision compatibility.
