It provides flame/no-flame indication and diagnostic information for the documented Limelight burner-management channel.

Which supply should be verified for DFI-100-340F?

Confirm a nominal 24 V DC supply within the documented 18 to 32 V DC range and preserve polarity and grounding.

How are field connections handled on DFI-100-340F?

Record every position on the pluggable terminal strip before removal and restore the same field-circuit and shield assignments.

What communication interface is documented for DFI-100-340F?

The authorized exact-model source identifies an integrated CANbus interface; record the connection and configuration before replacement.

What should be captured from the display of DFI-100-340F before service?

Record the alpha-numeric operating state and any diagnostic or fault code before isolating the module.

How should DFI-100-340F be commissioned after replacement?

Verify supply, terminal mapping, CANbus communication and stable diagnostics before the burner is permitted to enter a controlled light-off test.

Which safety test is required for DFI-100-340F?

Prove both flame-present recognition and flame-absent response, including the documented safe fuel-shutdown action.

What maintenance record should be retained for DFI-100-340F?

Retain the module identity, wiring map, supply measurement, CANbus state, diagnostic display record and final burner proof-test results.

Information

Overview Manuals Common Applications Product Precautions

DFI-100-340F provides local flame-state indication and diagnostic reporting within the documented Limelight burner-management arrangement.

Reports flame and no-flame operating states
Provides local alpha-numeric diagnostic indication
Communicates through the integrated CANbus interface
Uses a removable terminal strip for documented field connections

The module is connected to the existing flame-sensing circuit, 24 V DC supply, CANbus and burner-management logic through its pluggable terminal strip. Commissioning retains wiring identity and proves both flame recognition and safe no-flame response.

Important Notice: Confirm DFI-100-340F, the assigned Limelight burner-management channel, hardware execution, pluggable terminal strip, 24 V DC polarity, flame-sensor wiring, shields, grounding, CANbus configuration, displayed diagnostic state and controlled flame-failure test before commissioning.

Apter Power DFI-100-340F Manuals and Guides

The first document is the model-specific technical and system reference. The second is a distinct field workbook for installation, wiring, commissioning and acceptance records.

Burner flame supervision

Provides the documented flame-state indication used by the burner-management sequence.

Boiler light-off verification

Supports controlled confirmation of flame recognition during ignition testing.

Flame-circuit diagnostics

Uses the local status display and communication record to investigate abnormal response.

Module replacement validation

Reproduces the recorded terminal, supply and CANbus arrangement before a proof test.

Read the applicable Alstom installation instructions before work. Verify DFI-100-340F, the installed host system and all configured field interfaces before isolation, wiring or commissioning.

Confirm DFI-100-340F on the module marking and the assigned burner-management channel.

Place the fuel train and burner in the approved safe maintenance state.

Isolate the 24 V DC supply and apply ESD controls before handling the module.

Record every pluggable-terminal position, polarity, shield and field-circuit identifier.

Record the CANbus connection and alpha-numeric diagnostic status before removal.

Restore the approved burner-management configuration and documented supply range.

Verify stable power, communication and flame-state diagnostics before enabling fuel.

Complete controlled flame-present and flame-absent proof tests and verify safe shutdown action.

Alternative Names

Limelight DFI; Diagnostic Flame Indicator

Technical notes

Record the DFI-100-340F terminal strip, CANbus connection, power polarity, flame-sensor interface and displayed diagnostic code before removal. Restore the approved 24 V DC supply and burner-management configuration, then verify flame/no-flame response, fault reporting and safe burner shutdown under the controlled commissioning procedure.
