Eclipse 5603-32 Veri-Flame Control VF560332AA

Eclipse 5603-32 Flame Monitoring Control

The Eclipse 5603-32 Flame Monitoring Control (MPN: VF560332AA / 560332) is a microcomputer based high reliability burner management system for single burner applications. This instrument, a member of the Eclipse Veri-Flame family, provides accurate solid-state flame monitoring, controlling essential ignition timing sequences and safety shutoffs to protect industrial processing plants and marine auxiliary boilers.

The 5603-32 is designed for native 240 VAC operation and is ideal for systems that require reliable performance at high voltage, outside the scope of ordinary household power grids. Configured as a No-Purge control unit, it allows for fast, on-demand start sequences, with pre-purge cycles being controlled by upstream master logic or bypassed entirely according to process flow profiles. The controller offers field-selectable Trial For Ignition (TFI) intervals of 5 or 10 seconds so engineers may exactly match timing to fuel gas or oil light-off standards. This unit is primary safety defence against flame failure and is designed to interface with UV or self checking ultra violet scanners.

Technical Specifications: Eclipse 5603-32

Features

1. High Voltage Architecture 240 VAC: Designed for plants and vessels using 240V distribution networks, eliminating the requirement for step-down control transformers.
2. Field-Selectable TFI Windows: Compliant burner lighting can be achieved by using internal multi-position DIP switches to set either a 5-second or 10-second Trial For Ignition parameter.
3. Versatile sensor integration: Interfaces seamlessly with high-performance Eclipse 5600-90A and 5600-91 series Ultraviolet (UV) and Self-Check UV scanners for comprehensive flame monitoring fidelity.
4. Automated System Safety Lockout: The system shuts power to the fuel valve terminals within 3 seconds (+/- 0.5 seconds) when a loss of flame signal is detected, to prevent build-up of volatile gas.
5. Plug-In Base Mounting System For use with standard low profile wiring bases (such as 5602-10P or 5602-40 series) to facilitate rapid modular module changes without affecting existing terminal wiring enclosures.

Uses

• Marine Auxiliary & Exhaust Gas Boilers: Flame protection for ships’ oil-fired auxiliary boilers and thermal fluid heaters in automated machinery rooms.
• Industrial Hot Water & Steam Generators: Single-burner setups for thermal generation equipment in commercial and manufacturing settings, safely controlled.
• Process Air Heaters & Dryers: For textile, paper and food matrix processing ovens needing constant direct-fired heat inputs.
• Crucible & Smelting Furnaces Supervises safety criteria of the burner foundry ladle stations and secondary aluminum melting hoods.

Professional Insights from the Engine Room

• Interlock String Diagnostics: The 5603-32 features an internal safety protocol that monitors the air switch and combustion limit line inputs. If your controller drops out exactly 10 seconds into a startup sequence accompanied by a flashing failure state, do not immediately suspect the UV scanner. This is typically caused by a failure of the combustion air pressure switch failing to prove loop continuity within the assigned 10-second safety window.
• Scanner Maintenance Matrix: When matching this module to self-checking UV scanners (Model 5602-91), always verify the internal shutter operation cycle. In high-ambient temperature applications, UV lenses build up a micro-layer of soot or carbon film. Clean the optical face quarterly using an lint-free technical wipe dampened with pure isopropyl alcohol to keep the flame signal micro-amp readings well within steady-state limits.

Frequently Asked Questions

What does the “No-Purge” configuration mean for the Eclipse 5603-32?

A “No-Purge” configuration indicates that the control unit does not execute an automated pre-ignition air purging cycle when a call for heat is received. Instead, it immediately proceeds to the Trial For Ignition (TFI) stage. This module is designed for systems where the purging sequence is managed by an external Programmable Logic Controller (PLC) or where the process loop requires immediate ignition without delays.

How do I switch the Trial For Ignition (TFI) timing between 5 and 10 seconds?

• Timing adjustments are configured using the internal DIP switches located on the printed circuit board inside the module’s housing.
• To adjust the timing, isolate the main 240 VAC power supply and remove the control module from its wiring base.
• Locate the dual-position switch bank on the internal board.
• Toggle the designated switch according to the timing matrix printed on the internal label to select either the 5-second or 10-second safety window.

Can the Eclipse 5603-32 handle 120 VAC power input?

No. The Eclipse 5603-32 (MPN: VF560332AA) is wound and engineered strictly for 240 VAC (+10% / -15%) at 50/60 Hz. Applying 120 VAC will result in undervoltage faults, causing the internal safety relays to chatter or fail to pull in. If your system runs on a 120V line, you must use the corresponding 120V model in the Veri-Flame series (such as the 5603-12) or install a step-up control transformer.

What causes an immediate safety lockout on startup with a flame failure alarm?

If the unit locks out almost instantly when the ignition cycle begins, check the following variables:

• False Flame Signal: The controller checks for a flame signal before opening the fuel valves. If the UV scanner detects ambient light or an actual lingering flame before ignition, the unit will fault out.
• Improper Grounding: Flame monitoring circuits rely heavily on a solid electrical ground reference. Ensure the burner chassis and the control base share a common, low-impedance ground path.
• Faulty Scanner Alignment: If the UV scanner cannot view the root of the flame during the 5 or 10-second TFI window, the main fuel valve output (Terminal 5) will be instantly de-energized.

Is the Eclipse VF560332AA drop-in compatible with older 5603 series bases?

Yes. The VF560332AA utilizes the standard Eclipse Veri-Flame low-profile edge connector configuration. It is completely drop-in compatible with existing 5602-10P and 5602-40 mounting bases. You can swap the module without altering the field wiring terminations, provided the line voltage matches the 240 VAC requirement.

What is the exact Flame Failure Response Time (FFRT) for this control?

The nominal FFRT for this module is 3.0 seconds. If the flame signal drops out during steady-state operation, the internal microcomputer registers the loss and cuts power to the safety shutoff valves within a window of 2.5 to 3.5 seconds, preventing unburned fuel accumulation.
